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 to start operation.
NOTE:
•
Use the proper bit for the head of the screw/bolt
that you wish to use.
•
When fastening screw M8 or smaller, carefully
adjust pressure on the switch trigger so that the
screw is not damaged.
•
Hold the tool pointed straight at the screw.
•
If you tighten the screw for a time longer than
shown in the figures, the screw or the point of the
driver bit may be overstressed, stripped, damaged,
etc. Before starting your job, always perform a test
operation to determine the proper fastening time
