Torque limiter
NOTICE:
As soon as the torque limiter actuates,
switch off the tool immediately. This will help pre-
vent premature wear of the tool.
NOTICE:
Drill bits such as hole saw, which tend
to pinch or catch easily in the hole, are not appro-
priate for this tool. This is because they will cause
the torque limiter to actuate too frequently.
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the drill bit will stop
turning.
Electronic function
The tool is equipped with the electronic functions for
easy operation.
• Constant speed control
The speed control function provides the constant
rotation speed regardless of load conditions.
