charged battery: 1st gear: 0-370 r.p.m., 2nd gear:
0-1380 r.p.m., 3rd gear: 0
ತ

CAUTION
To avoid damage to the power tool, the switch must
be released (switched off) if the motor is stalled for
more than 2-3 seconds. After stalling, the power tool
must be allowed to run for 2 minutes under no load.
The speed of the power tool can be controlled
smoothly (increased from zero to maximum) by
pressing the control switch gradually.

CAUTION
In the event of the drill bit sticking, the power tool will
pivot about its own axis. Always use the power tool
with the side handle fitted and hold it securely with
both hands.
CAUTION
Use clamps or a vice to secure the workpiece. The
workpiece is thus held more securely than by hand
and both hands remain free to operate the power tool.
