Rotation only
For drilling in wood, metal or plastic materials, depress
the lock button and rotate the action mode changing
knob to the
symbol. Use a twist drill bit or wood bit.
Hammering only
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, scal-
ing 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 mecha-
nism, 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 prema-
ture 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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out
any work on the tool.
Side grip (auxiliary handle)
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.
Insert the bit into the tool. Turn the bit and push it in until
it engages.
