Operation
The proper fastening torque may differ depending upon the kind or size of screws, the type
of materials to be fastened, the condition of the threads, etc. Before starting your job, always
perform a test operation to verify adequate fastening torque.
Hold the tool firmly and place the point of the driver bit in the screw head. Apply forward
pressure
to
the tool to the extent that the bit will not slip off the screw and turn the tool
on. As soon as the screw becomes tight, the clutch will cut in and the motor will stop
automatically. Release the trigger.
NOTE:
Hold the tool pointed straight at the screw, or the screw and/or bit may be damaged.
If the motor will not start even after you pull the trigger, release the trigger. Then pull
the trigger again after turning the bit slightly with your fingers.
