When it is difficult to insert the bit, pull the sleeve
•
and insert it into the sleeve as far as it will go.
After inserting the bit, make sure that it is firmly
•
secured. If it comes out, do not use it.
Hook
014996
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw.
To remove, loosen the screw and then take it out.

•
for cooling down oil unit and motor during
operation. Failure to do so may cause the tool
excessive heat and damage.

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.
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.
•
For tightening bolt, select the soft or T mode
•
impact force grade.
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.
