mode changing knob to the
symbol. Use a tung-
sten-carbide tipped bit.

Hammering only
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 mech-
anism, be sure that the action mode changing
knob is always positively located in one of the
three action mode positions.
•
Do not force the action mode change knob or do
not move it from
symbol mode to
symbol
mode (or vise versa) at once. It may damage
the tool. When turning the knob from
sym-
bol mode to
symbol mode (or vise versa),
stop it at
symbol mode once. And rotate the
chuck clockwise (looking from the chuck side)
half turn or until it clicks. Then turn the knob to
the desired mode. If it is still difficult to turn the
knob, rotate the chuck again.
Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the out-
put 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)

Grooves
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 lon-
ger service life.

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.
