For optimal
performance and proper setting of self-drilling screws,
it is important that proper depth location and torque
setting be used. Varying the depth
control is accomplished by rotating the locking collar.
When the nosepiece contacts the fatened material, the
driving clutch disengages and the driver no longer turns
the screw. The torque control limits the torque (power)
output of the Kwik-Tapper screwdriver. The drive motor
will "ratchet" when the desired torque is
reached, helping to prevent overdriving or stripping of
the screw. This becomes very important when fastening
into thin or soft metals as well as using the Flo-Seal
screws.
For
best results, hold the Kwik-Tapper screwdriver
perpendicular to the work surface. Exert only enough
pressure to engage the clutch and then trigger the tool.
In driving, remember that the self-drilling screw must
first perform a drilling operation. This requires only a
nominal amount of pressure--let the Kwik-Tapper and drill
point do the work. The variable speed switch allows you
to control the drill speed to prevent "walking"
of the screwpoint.
