ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work
on the tool.
Side grip (Fig. 9)
CAUTION:
• Always use the side grip to ensure operating safety
when drilling in concrete, masonry, etc.
The side grip swings around to either side, allowing easy
handling of the tool in any position. Loosen the side grip
by turning it counterclockwise, swing it to the desired
position and then tighten it by turning clockwise.
Installing or removing the bit
Clean the bit shank and apply bit grease before installing
the bit. (Fig. 10)
Insert the bit into the tool. Turn the bit and push it in until
it engages. (Fig. 11)
If the bit cannot be pushed in, remove the bit. Pull the
chuck cover down a couple of times. Then insert the bit
again. Turn the bit and push it in until it engages.
After installing, always make sure that the bit is securely
held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the way
and pull the bit out. (Fig. 12)
Bit angle (when chipping, scaling or demolishing)
To change the bit angle, depress the lock button and
rotate the change lever so that the pointer points to the
O
symbol. Turn the bit to the desired angle. (Fig. 13)
Depress the lock button and rotate the change lever so
that the pointer points to the g symbol. (Fig. 14)
Then make sure that the bit is securely held in place by
turning it slightly.
Depth gauge (Fig. 15)
The depth gauge is convenient for drilling holes of uni-
form depth. Loosen the clamp screw and adjust the
depth gauge to the desired depth. After adjusting, tighten
the clamp screw firmly.
NOTE:
• The depth gauge cannot be used at the position where
the depth gauge strikes against the gear housing/motor
housing.
Dust cup (Fig. 16)
Use the dust cup to prevent dust from falling over the tool
and on yourself when performing overhead drilling
operations. Attach the dust cup to the bit as shown in
Fig. 16. The size of bits which the dust cup can be
attached to is as follows.
Dust cup 5
Dust cup 9

OPERATION
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. If you can see the red part on the upper
side of the button, it is not locked completely. Insert it
fully until the red part cannot be seen. If not, it may
accidentally fall out of the tool, causing injury to you or
someone around you.
• When operating overhead, always make sure the bat-
tery cartridge is locked securely so that it will not be
fallen out of the tool. If not, it may accidentally fall out of
the tool, causing injury to you or someone around you.
Hammer drilling operation (Fig. 17)
Set the change lever to the H symbol.
Position the bit at the location for the hole, then pull the
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 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.
Blow-out bulb (optional accessory) (Fig. 18)
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Chipping/Scaling/Demolition (Fig. 19)
Set the change lever to the g 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.
Drilling in wood or metal (Fig. 20)
Use the optional drill chuck assembly. When installing it,
refer to "Installing or removing the bit".
Set the change lever so that the pointer points to the
m symbol.
You can drill up to 13 mm diameter in metal and up to
27 mm diameter in wood.
Use a cutting lubricant when drilling metals. The excep-
tion is brass which should be drilled dry.
CAUTION:
• Never use "rotation with hammering" when the drill
chuck assembly is installed on the tool. The drill chuck
assembly may be damaged.
• 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 perfor-
mance and shorten the service life of the tool.
