Hook (Fig. 3)
The hook is convenient for hooking the tool to your belt. It
can be installed on either side of the tool.
Changing the installation position of hook allows two-way

unplugged before carrying out any work on the tool.
Installing or removing the bit
Loosen the thumb screws which secure the casing. Pull
out the casing in the direction of the arrow. (Fig. 4)
Press the dust cover toward the plane bearing and pull
out the bit. If the dust cover cannot be moved as far as the
plane bearing, try it again after turning the bit slightly.
To install the bit, insert it into the socket while turning it
slightly. After installing, always make sure that the bit is
securely held in place by trying to pull it out. (Fig. 5)
Setting for desired screw length (Fig. 6)
There are 3 positive-lock screw length settings. To obtain
the desired setting, pull out the stopper base while
depressing the lever until you see the number of the
desired screw length (indicated on the plate) appear to
rest on the very top edge of the casing. See the table
below for the relation between the number indicated on
the plate and the respective screw length ranges.

the workpiece.
• Do not apply oil or grease on the sliding surface of the
feeder box.

when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps. (Fig. 20)
