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.

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.

Use the optional drill chuck assembly. When installing it,
refer to "Installing or removing the bit" described on the
previous page.
Set the action mode changing knob so that the pointer
points to the symbol.
CAUTION:
Never use "rotation with hammering" when the drill
•
chuck assembly is installed on the tool. The drill
chuck assembly may be damaged. Also, the drill
chuck will come off when reversing the tool.
Pressing excessively on the tool will not speed up
•
the drilling. In fact, this excessive pressure will
only serve to damage the tip of your bit, decrease
the tool performance and shorten the service life
of the tool.
