NOTE:
If you connect a vacuum cleaner to your hammer,
•
cleaner operations can be performed. Dust cap
needs to be removed from the dust cup before the
connection.
OPERATION
CAUTION:
Always use the side grip (auxiliary handle) and
•
firmly hold the tool by both side grip and switch
handle during operations.
Hammer 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 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.

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.
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.
Blow-out bulb (optional accessory)

After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

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.
Drilling in wood or metal
CAUTION:
Never use "rotation with hammering" when the
•
quick change drill chuck is installed on the tool.
The quick change drill chuck may be damaged.
Also, the drill chuck will come off when reversing
the tool.
Pressing excessively on the tool will not speed up the

performance and shorten the service life of the tool.
There is a tremendous twisting force exerted on
•
the tool/bit at the time of hole breakthrough. Hold
the tool firmly and exert care when the bit begins
to break through the workpiece.
A stuck 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 firmly.
