Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the out-
put 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
►

Power-ON indicator lamp (green)
2.
Service indicator lamp (red)
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 car-
bon 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

Side grip
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

Bit grease
Clean the bit shank and apply bit grease before install-
ing the bit.
Insert the bit into the tool. Turn the bit and push it in until
it engages.

Chuck cover
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.

Pointer
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
symbol.
Turn the bit to the desired angle.
Depress the lock button and rotate the change lever so
that the pointer points to the
symbol. Then make sure
that the bit is securely held in place by turning it slightly.
Depth gauge

Clamp screw
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
►

Dust cup
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.
Bit diameter
Dust cup 5
6 mm - 14.5 mm
Dust cup 9
12 mm - 16 mm
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
symbol.
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light pres
-
sure 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.
