NOTE:
• When installing or removing the dust cup, the
cap may come off the dust cup. At that time, pro-
ceed as follows. Remove the bellows from the
attachment and fit the cap from the side shown
in the figure with its flat side facing upward
so that the groove in the cap fits in the inside
periphery of the attachment. Finally, mount the
bellows that has been removed.
NOTE:
• If you connect a vacuum cleaner to your ham-
mer, cleaner operations can be performed. Dust
cap needs to be removed from the dust cup
before the connection.

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
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.
NOTE: Eccentricity in the bit rotation may occur while
operating the tool with no load. The tool automatically
centers itself during operation. This does not affect
the drilling precision.

CAUTION:
Always use the side grip (auxiliary handle) and
firmly hold the tool by both side grip and switch
handle during operations.
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. Failure to do so may result
in the loss of control of the tool and potentially
severe injury.
