OPERATION
CAUTION:
Always use the side handle / side
grip (auxiliary handle) and firmly hold the tool by
both side handle / side grip and switch handle
during operations.
CAUTION:
Always make sure that the work-
piece is secured before operation.
Failure to prop-
erly secure the workpiece may cause the workpiece
to move resulting in injury.
CAUTION:
Do not pull the tool out forcibly
even the bit gets stuck. Loss of control may
cause injury.
CAUTION:
Do not leave the tool stabbed in
the workpiece.
Otherwise the tool may starts unin
-
tentionally and cause an injury.
NOTE:
If the battery cartridge is in low temperature,
the tool’s capability may not be fully obtained. In this
case, warm up the battery cartridge by using the
tool with no load for a while to fully obtain the tool’s
capability.
Hammer drilling operation
CAUTION:
There is tremendous and sudden
twisting force exerted on the tool/drill bit at the time of
hole break-through, when the hole becomes clogged
with chips and particles, or when striking reinforcing
rods embedded in the concrete.
Always use the side
grip (auxiliary handle) and firmly hold the tool by
both side grip and switch handle during opera-
tions.
Failure to do so may result in the loss of control
of the tool and potentially severe injury.
Set the action mode changing knob to the
symbol.
Position the drill bit at the desired location for the hole,
then pull the switch 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, then remove the drill bit partially from the hole.
By repeating this several times, the hole will be cleaned
out and normal drilling may be resumed.
