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 you can continue drilling operation.
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 rein-
forcing 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, and maintain good balance
and safe footing. Failure to do so may result
in the loss of control of the tool and potentially
severe injury.
