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.
Set the action mode changing knob to the
Position the drill 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 drill bit partially from the hole.
By repeating this several times, the hole will be cleaned
out and normal drilling may be resumed.
NOTE: Eccentricity in the drill bit rotation may occur
while operating the tool with no load. The tool auto-
matically centers itself during operation. This does not
affect the drilling precision.
Chipping/Scaling/Demolition
Set the action mode changing knob to the symbol.
Hold the tool firmly with both hands. Turn the tool on
and apply slight pressure on the tool so that the tool will
not bounce around, uncontrolled.
Pressing very hard on the tool will not increase the
efficiency.
