NOTE: The depth gauge cannot be used at the posi-
tion where the depth gauge touches against the gear
housing/motor housing.
OPERATION
CAUTION: Always use the side grip (auxiliary
handle) and rmly hold the tool by both side grip
and switch handle during operations.
CAUTION: Always make sure that the work-
piece is secured before operation.
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 rmly hold the tool by
both side grip and switch handle during opera-
tions. Failure to do so may result in the loss of control

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.

Drilling in wood or metal
CAUTION: Hold the tool rmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION: A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it rmly.
CAUTION: Always secure workpieces in a
vise or similar hold-down device.
NOTICE: Never use “rotation with hammering”
when the drill chuck is installed on the tool. The
drill chuck may be damaged.
Also, the drill chuck will come off when reversing the tool.
NOTICE:
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 drill bit, decrease the
tool performance and shorten the service life of the tool.
