Rotation only (Fig. 7)
For drilling in wood, metal or plastic materials, depress the
lock button and rotate the change lever so that the pointer
points to the symbol. Use a twist drill bit or wood bit.
Hammering only (Fig. 8)
For chipping, scaling or demolition operations, depress
the lock button and rotate the change lever so that the
pointer points to the symbol. Use a bull point, cold chisel,
scaling chisel, etc.
CAUTION:
• Do not rotate the change lever when the tool is running
under load. The tool will be damaged.
• To avoid rapid wear on the mode change mechanism,
be sure that the change lever is always positively
located in one of the three action mode positions.
Torque limiter
The torque limiter will actuate when a certain torque level
is reached. The motor will disengage from the output
shaft. When this happens, the bit will stop turning.
CAUTION:
• As soon as the torque limiter actuates, switch off the
tool immediately. This will help prevent premature wear
of the tool.
Indicator lamp (Fig. 9)
The green power-ON indicator lamp lights up when the
tool is plugged. If the indicator lamp does not light up, the
mains cord or the controller may be defective. The
indicator lamp is lit but the tool does not start even if the
tool is switched on, the carbon brushes may be worn out,
or the controller, the motor or the ON/OFF switch may be
defective.
The red service indicator lamp lights up when the carbon
brushes are nearly worn out to indicate that the tool needs
servicing. After approx. 8 hours of use, the motor will
automatically be shut off.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Side grip (Fig. 10)
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 counter clockwise, swing it to the desired
position and then tighten it by turning clockwise.
Installing or removing the bit (Fig. 11)
Clean the bit shank and apply bit grease before installing
the bit.
Insert the bit into the tool. Turn the bit and push it in until it
engages. (Fig. 12)
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. 13)
Bit angle (when chipping, scaling or
demolishing) (Fig. 14)
The bit can be secured at 24 different angles. To change
the bit angle, depress the lock button and rotate the
change lever so that the pointer points to the
Turn the bit to the desired angle.
Depress the lock button and rotate the change lever so
that the pointer points to the
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 uniform
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 the
figure. The size of bits which the dust cup can be attached
to is as follows.
Dust cup 5
Dust cup 9
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 (Fig. 17)
Set the change lever 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:
• When the bit begins to break through concrete or if the
bit strikes reinforcing rods embedded in concrete, the
tool may react dangerously. Maintain good balance and
safe footing while holding the tool firmly with both
hands to prevent dangerous reaction.
