OPERATION
CAUTION:
Always use the side grip (auxiliary
handle) and firmly hold the tool by both side grip
and switch handle during operations.
CAUTION:
Always make sure that the work-
piece is secured before operation.
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.
