Dust cup

and on yourself when performing overhead drilling
operations. Attach the dust cup to the bit as shown in the
figure. The size of bits which the dust cup can be
attached to is as follows.

Set the action mode changing knob to the
Position the 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 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
operations. Failure to do so may result in the loss of
control of the tool and potentially severe injury.
