INTRODUCTION
------------
Why computerize the preventive maintenance and work order
system? If your operation handles more than a couple of hundred
work requests per week, it is very easy for many to "fall through
the crack" or get lost in a paperwork system. Once a work
request arrives and is passed on to the appropriate trade
supervisor, you have no immediate record of the request or
control over the prioritization or scheduling.
Have you ever wondered how much output you are getting from
your employees? Does it take an inordinate amount of time to dig
up information on how much was spent on repairs for a particular
piece of equipment? Can you easily document how much was spent
on repairs for a certain department due to the department's
neglect or abuse of equipment? Once set up does your preventive
maintenance system keep an employee occupied pulling cards or
writing up preventive maintenance work orders? Do you know what
your corrective and preventive maintenance backlogs are? Have
you ever had to hunt through file drawers to find a part number
or lubricant type for a piece of equipment? Do you know how many
of the outstanding work requests are 1 week, 2 weeks, 1 month, or
2 months old? Do you know how much spare parts inventory is
sitting on the shelf? Do you have too many last minute parts
purchases because someone forgot to tell you when the supply got
low? Do you have $3000-$15,000 to spend on a commercial
maintenance software package?
If you honestly answered the above questions, then you
should begin to think about how the PC MECHANIC MAINTENANCE
MANAGEMENT SYSTEM may be an organizational tool to help you.
How? Because a computerized work order and preventive
maintenance system can do the necessary number crunching and
menial tasks such as retrieving records, printing work
assignments, posting to records, and report generation that may
be too much for your present staff.
The PC MECHANIC is an application written in the dBASE
programming language. Although dBASE is a very powerful database
management program, it can be very difficult for people to use.
To use the PC MECHANIC, you don't have to know the first thing
about dBASE. I've done the hard work writing a totally menu-
driven system that is E A S Y to use. The menus and input
screens almost make these instructions unnecessary. Depending on
how most people will need information in reports, I've built in a
lot of flexibility to search based on different criteria.
Since we touched on the subject of programming, let me tell
you a little about myself. I don't claim to be a programmer as
can be evidenced by a look at some of my source code. It might
PC MECHANIC
Page 3
not be pretty, but it somehow manages to work. I do think I know
a little about maintenance and computerized maintenance systems.
My full-time employment is in the area of energy management and
maintenance for a major U.S. hospitality company. I am involved
every day with building maintenance personnel and have been
exposed to a number of maintenance software packages over the
past few years. My two main gripes about most maintenance
software are the high cost and complexity for the typical user.
Armed with a rebellious spirit to stick it to the greed-
mongers charging thousands, a desire to better learn dBASE
programming, and a wild fantasy that I might actually be able to
keep my wife in mink and diamonds, I set out to write a shareware
maintenance management program that would be easy to use. What
is shareware? I like to think of it as "test drive before you
buy". Try it. If you don't like it, throw it away or burn it.
You haven't lost anything. If you do find you like it and it
benefits your operation, then most shareware authors request that
you send in a registration payment to the author to reward him
for his efforts. Most shareware authors urge you to spread
copies of their program around to friends, associates, user
groups, or bulletin boards. Some authors warn that if you
continue to use their program and don't send in the registration
payment, you will suffer from bad Karma, guilt trips, or swarms
of locusts.
I think I am a little more reasonable and to the point. I
hold the copyright to this program. If you think it is lousy,
don't use it. Better yet, drop me a note telling me your beef
and I will do my best to incorporate your suggestions into the
program. If you do like it and use it, I would suggest a
registration payment of $50.00 or whatever amount you would like
to contribute to my wife's mink and diamonds fund. In all
seriousness, let me say that I have invested many, many hours of
my free time writing the PC MECHANIC. I would like to think that
someone appreciates it enough to register, or at least enough to
send a note with comments. Registered users will be notified of
future updates, which will be available at minimal cost. For
everyone, I will be available for help and questions. My home
telephone number is (312) 869-0114. I can also be reached on
Compuserve, user ID# 71121,2014. If it is during the day and it
is an emergency, my wife can give out my office number, but I
prefer to keep this to a minimum. Registration payments or
questions can be sent to:

Whether you become a registered user or not, I hope you find
that the PC MECHANIC provides many of the functions of commercial
PC MECHANIC
Page 4
maintenance management software in an easy-to-use, inexpensive
package.
At some point in the documentation, most folks usually put
some sort of legal disclaimer stating that they are not
responsible for anything. Upon strong legal recommendation, I
have included similar wording at the beginning of this manual. I
have spent a lot of time trying to find all of the bugs in the PC
MECHANIC. It should be relatively bug-free, however, I can't
give a 100% guarantee. What I will promise is that if you find a
bug and notify me, I will do my best to correct it. As far as
liability is concerned, if you manage to blow up a boiler or eat
through the condenser tubes in a chiller, then it's your own damn
fault.
INSTALLATION & HARDWARE REQUIREMENTS
------------------------------------
Hardware & Software:
-IBM or compatible PC, 640K ram memory recommended
-Hard disk drive
-Color monitor recommended
-Dot matrix printer for work orders, reports, listings,
etc.
-DOS 2.0 or above
-Interpreted BASIC (filename BASICA.COM) from your DOS
(Disk Operating System) disk
-Backup and restore programs (filenames BACKUP.COM and
RESTORE.COM), also from your DOS disk
Forms Requirements:
-3.5 inch high continuous feed paper is recommended for
printing of work orders and preventive maintenance work
orders. This is a convenient size as work orders printed
in condensed print easily fit in a maintenance engineer's
shirt pocket. There are probably many possible sources
for this paper, however, 2 that I know of are:
Visible Computer Supply, St. Charles, IL
tel. 312-377-0990
3.5 inch by 5 inch continuous file cards(index card
size), catalog # DP325 TFC, 5000/carton
Moore Business Forms,3.5 inch by 8.5 inch, 2 part
continuous feed paper, 3700 sheets/box, mfg.# FO-450
Installation:
Beginning with this version of PC MECHANIC (version 1.2), it
PC MECHANIC
Page 5
is no longer necessary to use dBASE III Plus or dBASE IV.
PC MECHANIC now runs stand-alone, so you don't need anything
else. Additionally, it runs much faster now than under the dBASE
interpreter. The first time installation of PC MECHANIC should
follow the steps below. If you already have PC MECHANIC running
on your PC, go to step 4 below.
1. Turn on your PC and wait until you have the C> prompt,
or whatever hard disk drive you want to use. During
these instructions I will refer to the C> prompt or the
"C" drive for your hard disk. You could be set up with
a different drive letter so substitute yours
accordingly.
2. Place the PC MECHANIC disk in the "A" diskette drive.
Type in "A:INSTALL" (without the quotes) and hit the
enter key.
3. Put the DOS disk which contains interpreted BASIC
(BASICA.COM) in the "A" diskette drive. Without typing
the quote marks, enter the following:"COPY
A:BASICA.COM" and hit the enter key. This will copy
the BASIC interpreter to your PC MECHANIC subdirectory.
PC MECHANIC uses a short basic program to set the
printer for 3.5 inch high forms/condensed print,
condensed print only, and resets the printer for normal
print. This should work for most Epson/IBM/Okidata
printers. If your printer is different, consult your
printer manual for the proper escape codes to use.
Since most printer manuals give the correct printer
codes with examples in BASIC, I decided to opt for this
and allow users to edit the program (PRINTER.BAS).
If this sounds like Greek, find someone familiar
with BASIC, printer programming, or contact me.
4. With the DOS disk still in the "A" diskette drive, type
in without the quote marks, "COPY A:BACKUP.COM", and
hit the enter key. Next type in without the quote
marks, "COPY A:RESTORE.COM", and hit enter.
5. You have just finished the first part of the
installation process. You now have a subdirectory on
your hard drive called \PCMECH. The PC MECHANIC
executable program and report format files have been
transferred to this subdirectory. Also, you have
copied three files from your DOS disk to this
subdirectory.
PC MECHANIC
Page 6
6. If you already have an earlier version of PC MECHANIC
running on your PC, you just need to copy the PC
MECHANIC disk to the proper subdirectory. Type in
without the quote marks, "CD PCMECH" and hit enter.
Put the PC MECHANIC disk in the "A" drive and type in
"COPY A:*.* and hit enter.
GETTING STARTED
---------------
That's all there is to it. To fire up PC MECHANIC, you must
be at the C> prompt and in the PC MECHANIC subdirectory. To make
sure you are in the correct subdirectory, type in without the
quote marks, "CD PCMECH" and hit the enter key. Then type
"PCMECH" and hit enter. You will soon see the PC MECHANIC title
screen for a few seconds, next the shareware message (otherwise
known as a commercial message from the sponsors), next a prompt
to make sure that you have set the caps lock on, and finally, the
main menu will be displayed.
In basic usage, menu selection is made by highlighting the
item with the up and down arrow cursor keys and hitting enter or
by hitting the number key corresponding to the desired choice,
ie: hit 6 to enter the UTILITIES SYSTEM. In fact, that's exactly
what you should do now. Before you can use the system, we have
to enter the UTILITIES SYSTEM and create the database files.
Highlight this menu option and hit enter or just hit the number
6. At the UTILITIES SYSTEM menu, select option 5, which is for
FIRST TIME INSTALLATION. The other menu options will be
explained later. When the installation process has finished, you
will be shown the UTILITIES SYSTEM menu again. Select option 6,
which will return you to the main menu.
Most menus and data entry screens are fairly intuitive as to what
you should type in. When filling in the data entry screens, if a
piece of information is not known, leave the field blank. If you
are ever unsure of an entry or menu option, one of the
enhancements to this version of PC MECHANIC is context sensitive
help. You access this by hitting the F1 function key. Remember,
HELP IS ACCESSED BY HITTING F1. When you complete a field, hit
enter or the down arrow key to position the cursor at the start
of the next field. If you make a mistake and haven't left a
field yet, you have the left & right arrows, backspace, delete,
and insert keys available for editing the data field. Sometimes,
you can move back one field by hitting the up arrowkey. This will
vary due to the usage of dBASE READ commands. Finally, if you
PC MECHANIC
Page 7
make a mistake, continue entering data in the remaining fields.
When you get to the bottom of the screen, you will be asked if
everything is OK. The normal response is Y for yes or N for no.
By hitting N, or just enter since the default is no, you can step
back through the data fields and make corrections where
necessary. If a field is OK, just hit enter to move on to the
next field.
In these instructions, there will be many instances where
you will be told to type in something. The proper keystroke or
keystrokes will be shown within quotation marks, such as these
"". What you type in should be the keystrokes contained within
the quote marks, but not including the quote marks.
UTILITIES SYSTEM
----------------
The UTILITIES SYSTEM is accessed by selecting option 6 from
the PC MECHANIC main menu. When you enter the system, you will
be presented with the utilities menu. The options to select are
as follows:
1. BACKUP DATABASE FILES
2. RESTORE DATABASE FILES
3. REBUILD INDEXES
4. CONVERT FROM PREVIOUS VERSION
5. FIRST TIME INSTALLATION
6. RETURN TO MAIN MENU
Option 1 will perform a DOS backup of all the database
files. You should have several blank formatted diskettes
available to do this. As the size of the databases grow, you
will need additional diskettes. The disks should be labelled in
sequence, ie:Backup #1, Backup #2, Backup #3, etc. It is VERY
IMPORTANT that you keep the disks in sequence. YOU should also
do the backup operation EVERY DAY. It doesn't take very long and
will save your skin one day when your hard disk decides to go off
to never-never land. It should be noted that the program is hard
coded to backup to the "A" diskette drive. If you have violent
problems with this, perhaps, I can re-compile a modified version
for you which will backup to a different drive.
Option 2 performs a DOS restore of all the database files in
the PC MECHANIC subdirectory. If you ever lose your hard disk,
or buy a new computer and want to set everything up on the new
machine, you will be glad to have this option.
Option 3 rebuilds all of the indexes. I won't try to
explain what indexes are-only that they help the system keep
PC MECHANIC
Page 8
records in order. If the indexes should get corrupted by a power
failure or other misfortune, this option should rebuild them
cleanly.
Option 4 allows the user to convert from an earlier version
of PC MECHANIC. Before using this version for the first time,
select the conversion option. When it has finished, you will be
returned to the utilities menu and you will be ready to go.
Option 5 we already covered and should be used before the
very first time PC MECHANIC is run.
Option 6 returns the user to the PC MECHANIC main menu.
INVENTORY SYSTEM
----------------
To enter the inventory system, select #1 at the main menu.
The menu selection items you will be shown are:
1. Enter/Modify/Delete Parts Records
2. Issues/Returns Transactions
3. Vendors Database
4. Purchases Records
5. Reports Menu
6. Return to Main Menu
Enter/Modify/Delete Parts Records:
If you want to set up the inventory system, probably the
first area to enter is the Vendors Database. The reason for this
is that the vendor identification number will be needed for the
parts records. The vendor data to enter is pretty much self-
explanatory. The vendor identification # is generated by the
computer and will be needed in other parts of the program. When
all data inputs have been made,you will be prompted if everything
is OK or not. The response should be "Y" for yes or "N" for no.
When you are satisfied with the inputs and answer "Y" to
everything OK, the next prompt will be a blinking "MORE". This
is asking if you have more entries to make. Again, the proper
response is "Y" for yes or "N" for no.
Assuming the vendors database has been set up, you will want
to set up the parts records. Select item #1 at the inventory
system menu. You will then be given the options to enter,
modify, delete, or return to the previous menu. Some notes about
PC MECHANIC
Page 9
entering parts records are in order. The Item # is a part number
which YOU assign to each part. You may want to start at 1 and
sequentially number every item, or you may want to devise a
letter and number code to describe the part. Mfg., is the
manufacturer. Cat. # is the manufacturer's catalog or ordering
number. Location is described by storeroom (Strm.), row in the
storeroom, shelf in the row, and bin number on the shelf. The
program allows for two storeroom locations. Desc. is for a
description of the part, and can be 2 lines of 40 characters
each. Value is the total opening value of the item stocked. This
will be updated automatically as you issue material or receive
purchases. Qty.on Hand is the quantity on hand. Reorder at is
the level of inventory the part quantity must fall to before it
is reordered. Reorder Qty. is the amount that should be
reordered based on previous experience. Unit price is the quoted
price the last time the item was ordered. This should be updated
each order. In the section for vendors, you only need to enter
the vendor ID# and the system will bring up the company name of
the vendor. There is space to enter 3 vendors who carry the
particular part. At the end, you will be prompted if everything
is OK and if there are more entries to be made.
Issues/Returns Transactions:
The second selection choice is for transactions such as
issues and receipts of items ordered, and also returns to the
storeroom. To handle receipts, a record must be set up
previously in the purchases section of the inventory system.
When the transactions choice is made, a sub-menu will be shown.
The choices on this menu are parts issued, parts returned,
receipts of items ordered, delete old transactions, and return to
the inventory system menu.
Issues and returns are identical in the data input screen.
The first field is date, which defaults to the current date.
Type over this date or hit enter to accept the date. The next
field is item, where you should enter the part number of the
item. Description is system generated. If you want to track the
transaction to a work order or preventive maintenance work order,
enter the appropriate work order number or PM work order number.
Next, enter the quantity of the part issued or returned to stock.
After the prompt asking if everything is OK, the average cost and
value of the part will be displayed. The quantity on hand and
value of the part will be automatically updated to account for
the transaction.
To enter parts received, the data fields to input are date,
purchase order number (PO#), part #, vendor ID#, and quantity
received. The part description and vendor company name are
generated by the computer. If everything is OK, the value and
updated quantity backordered will be displayed.
PC MECHANIC
Page 10
To delete old transactions, you will be prompted to enter a
cut-off date. All transactions before this date will be deleted
from the database. Only use this option when you are sure you
will not need to access the transaction information again.
The purchases database is used to track items ordered and
purchases by vendor. The data input fields are discussed below.
Date defaults to the current system date. Type over this or hit
enter to accept the date. P.O. # is the purchase order number.
Part # is the part identification number you set up previously.
Vendor ID is the vendor identification number. Description and
vendor name are generated by the system. The next inputs are for
the quantity ordered and unit price to pay. Ext. Cost is the
extended cost and is system generated. The Qty. Backordered is
is the quantity back ordered and is initially set equal to the
quantity ordered.
The reports menu contains selections for a number of
inventory system reports. The parts listing is a basic list of
all parts by part number, description and other information. The
vendor listing is an alphabetic listing of vendors,
identification numbers, contacts, and phone numbers. The reorder
report is a listing of all parts where the quantity on hand has
fallen below or is equal to the reorder level. The consumption
report is a listing of usage over a user specified period of
time, which also includes value of parts used. The purchases by
vendor report gives the breakdown over a period of time of
purchases from each vendor. It could be very useful to see if
any favoritism is being shown to a particular vendor. The
backorder report lists those items where the date promised has
passed and the item has not been received yet. The final menu
choice is to return to the inventory system main menu.
WORK ORDER SYSTEM
-----------------
To enter the work order system, select item #2 from the main
menu. The work order system menu will then display the following
choices:
1. Enter New Work Orders
2. Edit/Display/Reissue Work Orders
3. Close Out Completed Work Orders
4. Reports Menu
5. Delete Old Work Orders
6. Return to Main Menu
To enter new work orders into the system, select item # 1.
The first thing to happen is that the BASIC program for setting
PC MECHANIC
Page 11
up your printer will be loaded into memory. To print work orders
in condensed mode and set the form length to 3.5 inches, select
option #1 "SET UP PRINTER FOR WORK ORDERS" and hit enter. Make
sure your printer is turned on to avoid time out errors. You
will then see displayed the data input screen for entering work
orders. The work order number is generated by the computer and
is the reference number you will use later to track the work
order. The current date is the default, so you can accept it by
hitting enter or change it by typing over the date. The other
fields to input are the equipment identification number,
department making the work request or reporting the problem,
location, person requesting the work, and responsible trade for
the job. Priority can be input, as 1,2,3 or A,B,C or whatever
system you may want to use. The work description fields allow
you to enter up to 3 lines, each 40 characters long, which should
be sufficient for most jobs. When you are finished, you will be
prompted if everything is ok. The response should be "Y" for yes
or "N" for no. You will then be prompted if you want to print
out the work order. Again, the response to the prompt is "Y" or
"N", without the quote marks. Next, will be displayed a flashing
prompt with the word "MORE". This is the prompt asking if you
have more work orders to input or if you are finished. The
proper response is "Y" or "N". When you are finished, the BASIC
printer control program will again be loaded into memory. You
can select option #3 to reset the printer to normal printing and
form length.
A word of advice is offered here to avoid future headaches.
Make up a list of standard codes for the various trades you
employ and another list of standard location names or
abbreviations. These should be used to develop consistency in
data input and will be necessary later on when you want to
request a report for a specific trade or location. If an exact
match is not made to what you request, there will be no report or
records will be missed. For example, if part of the time you
enter "CA" as a trade code for carpenter, and part of the time
you enter "CARP", the system will interpret these as 2 separate
trades. If you request a report for all backlogged work
belonging to the trade "CA", all work orders entered for "CARP"
will be overlooked. Be careful.
To edit, display, or reissue (reprint) a work order, select
item #2 at the work order system menu. The input screen is
identical to the new work order entry screen, so there is no
further discussion of this item needed.
To close out completed work orders, select item # 3 from the
work order system menu. Enter the work order # when prompted to
do so. You will then see the original work order data entry
screen,however, there are some additional input fields. Status
should be updated to complete by entering "C" (without the quote
PC MECHANIC
Page 12
marks) in the status field. Date complete and remarks, for any
appropriate comments are self explanatory. There are fields to
enter the identification numbers of up to 3 employees who
participated in doing the job. These are entered one at a time.
You enter the employee's ID# and the system displays the
employee's last name. Enter the number of hours the employee
devoted to the job and the system calculates and displays the
labor cost associated with that particular employee. The system
then totals up the labor cost for the job. You can also enter up
to 3 parts used also. This operates in a similar manner. Enter
the part number, and the system displays a shortened part
description. Enter the quantity used, and the system calculates
and displays the part cost. After entering up to 3 parts used,
the system totals the parts cost. You will then get the familiar
prompt asking if everything is OK or not. Answer with "Y" or
"N". A new prompt will then be displayed asking if you want to
automatically update the inventory files. In a large operation
with a full-time storeroom clerk, you would most likely answer
"N" for no to this prompt as issues will probably be handled from
the storeroom and tracked there. For a smaller operation, I have
added this option so that the inventory quantity and value can be
reduced by the proper amounts without requiring the user to exit
from the work order screen and enter the inventory system. If
you want to update the inventory files, enter a "Y" for yes. Use
a little caution here to avoid "double dipping" or deducting from
inventory at the storeroom and when closing out the work order.
The next prompt will be the flashing MORE?, asking if you have
more to close out. The familiar response is "Y" for yes or "N"
for no.
Selection of item #4 from the work order system menu will
bring up the menu of available reports. Item #1 of this menu is
for a backlog listing of all work orders, sorted by trade. Items
#2,3, or 4 will generate a backlog report for a specific trade,
location, or piece of equipment. The user is prompted to enter
the search string. Item # 5 is for the work order aging report.
By trade, this will list the number of work orders of different
ages, ie: 0-7 days, 8-14 days, etc. Items #6&7 are for work
history reports sorted by a specific location or piece of
equipment. The user again is prompted to enter the search
string. Item #8 returns the user to the work order system main
menu.
After a period of time, the size of the work history
database will probably get quite sizeable. You may determine
that you don't need to keep this information for longer than 3
months, 6 months, or 1 year. To delete old work orders from the
history database, select item #5 from the work order system main
menu. You will be prompted to enter a cutoff date. All work
orders with a completion date before the cutoff date will be
purged from the database. Use this option with CAUTION.
PC MECHANIC
Page 13
Menu item # 6 will return the user to the PC MECHANIC main
menu.
PREVENTIVE MAINTENANCE SYSTEM
-----------------------------
