For chipping, scaling or demolition operations, depress
the lock button and rotate the action mode changing
knob to the symbol. Use a bull point, cold chisel,
scaling chisel, etc.
CAUTION:
Do not rotate the action mode changing knob when
•
the tool is running. The tool will be damaged.
To avoid rapid wear on the mode change
•
mechanism, be sure that the action mode
changing knob is always positively located in one
of the three action mode positions.
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.

CAUTION:
Always use the side grip to ensure operating
•
safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on 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; 0.02 - 0.04 oz.). 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.
