"hammering only" to "rotation only" or from "rotation only"
to "hammering only". First set the change lever and the
shift lever to "rotation with hammering" mode position
shown in figure. Then set them to the position for
"hammering only" or "rotation only".

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

003137
The green power-ON indicator lamp lights up when the tool is
switched ON. If the indicator lamp is lit but the tool does not
start, the carbon brushes may be worn out, or the electric cir-
cuit or the motor may be defective. If the indicator lamp does
not light up and the tool does not start, the ON/OFF switch or
the mains cord 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 auto-
matically be shut off.
