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.
CAUTION:
Do not pull the tool out forcibly even
the bit gets stuck. Loss of control may cause injury.
CAUTION:
The dust collection system is
intended for drilling in concrete only. Do not use the
dust collection system for drilling in metal or wood.
CAUTION:
When using the tool with the dust
collection system, be sure to attach the filter to the
dust collection system to prevent dust inhalation.
CAUTION:
Before using the dust collection
system, check that the filter is not damaged.
Failure to do so may cause dust inhalation.
CAUTION:
The dust collection system col-
lects the generated dust at a considerable rate,
but not all dust can be collected.
NOTICE:
Do not use the dust collection system
for core drilling or chiseling.
NOTICE:
Do not use the dust collection system for
drilling in wet concrete or use this system in wet envi-
ronment. Failure to do so may cause malfunction.
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.
