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 M8 or smaller screw, choose a
proper impact force and carefully adjust pressure
on the switch trigger so that the screw is not
damaged.
• Hold the tool pointed straight at the screw.
• If the impact force is too strong 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 for your screw.
