OPERATION
Hammer drilling operation
Set the change lever to theufl
symbol.
Position the bit at the location for the hole,
then pull the trigger.
Do
not force the tool. Light pressure gives
best results. Keep the tool in position and
prevent it from slipping away from the hole.
Do
not apply more pressure when the hole
becomes clogged with chips
or
particles.
Instead, run the tool at an idle, the remove
from the hole.
By
repeating this several
times, the hole will be cleaned out.
CAUTION:
When the bit begins to break through concrete or
if
the bit strikes reinforcing rods em-
bedded in concrete, the tool may react dangerously. Maintain good balance and safe foot-
ing while holding the
tool
firmly with both hands to prevent dangerous reaction.
Torque limiter
The torque limiter
will
actuate when a certain torque level is reached. The motor will disen-
gage 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 pre-
vent premature weak of the tool.

hipping/Scaling/Demolition
Set the change lever to the symbol. Hold
the tool firmly with both hands. Turn the
tool on and apply slight pressure on the tool
so
that the
tool
will not bounce around,
uncontrolled. Pressing very hard on the tool
will not increase the efficiency.
