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.

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.

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.
