The side grip is convenient for downward drilling or chip-
ping operations. Screw the side grip on the tool securely.
The side grip can be installed on either side of the tool for
right or left hand operation.
Installing or removing the bit
Insert the bit into the tool holder as far as it will go. Pull
out and turn the tool retainer 180 degrees. Then release
it to secure the bit.
CAUTION:
• Never use A-type shank bits. They can cause dam-
age to the tool.

OPERATION

Hammer drilling operation
Set the change lever to the
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light pres-
sure gives best results. Keep the tool in position and pre-
vent 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 bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
CAUTION:
• There is a tremendous and sudden twisting force
exerted on the tool/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 con-
trol of the tool and potentially severe injury.
Blow-out bulb (optional accessory)
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
