For chipping, scaling or demolition operations, 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 under load. 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.
• When changing from the symbol mode to the
symbol mode, the action mode changing knob
may no longer move in the
symbol position. At
this time, turn the tool on or turn the chuck by hand
in the
symbol position and then rotate 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.
• Bits such as hole saw, which tend to pinch or catch
easily in the hole, are not appropriate for this tool.
This is because they will cause the torque limiter to
actuate too frequently.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Side grip (auxiliary handle)

010713
CAUTION:
• Always use the side grip to ensure operating safety.
Install the side grip so that the protrusions on the grip fit
in between the grooves 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).
This chuck lubrication assures smooth action and longer
service life.
