in the
action mode changing knob. Forcing the action
mode changing knob may cause tool damage.
Torque limiter
The torque limiter will actuate when a certain torque level
is reached. The motor will disengage from the output
shaft. When this happens, the bit will stop turning.
CAUTION:
As soon as the torque limiter actuates, switch off
•
the tool immediately. This will help prevent
premature wear of the tool.
Hole saws cannot be used with this tool. They tend
•
to pinch or catch easily in the hole. This will cause
the torque limiter to actuate too frequently.

Side grip (auxiliary handle)
Fig.10
CAUTION:
Always use the side grip to ensure operating safety.
•
Install the side grip so that the protrusion on the grip fit in
between the grooves in the tool barrel. Then tighten the
grip by turning clockwise at the desired position. It may
be swung 360° so as to be secured at any position.
Bit grease
Coat the bit shank head beforehand with a small amount
of bit grease (about 0.5 -1 g). This chuck lubrication
assures smooth action and longer service life.
Installing or removing the bit
Clean the bit shank and apply bit grease before installing
the bit.
Fig.11
Insert the bit into the tool. Turn the bit and push it in until it
engages.
Fig.12
If the bit cannot be pushed in, remove the bit. Pull the
chuck cover down a couple of times. Then insert the bit
again. Turn the bit and push it in until it engages.
After installing, always make sure that the bit is securely
held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the way
and pull the bit out.

Bit angle
(when chipping, scaling or demolishing)
Fig.14
The bit can be secured at the desired angle. To change
the bit angle, depress the lock button and rotate the
action mode changing knob to the O symbol. Turn the bit
to the desired angle.
Depress the lock button and rotate the action mode
changing knob to the symbol. Then make sure that the
bit is securely held in place by turning it slightly.

Depth gauge
Fig.16
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the side grip and insert the depth
gauge into the hole in the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip.
NOTE:
The depth gauge cannot be used at the position
•
where the depth gauge strikes against the gear
housing.
