locking mechanism make sure that these screws are
used, and not longer or shorter ones. Failure to do so will
pose an accident hazard due to blocking of the spindle
wheel or to inadequate fastening of the safety guard.

The additional handle must be screwed in at the left or
right, or in the gearbox head at the top.

tArting current limitAtion
The electronically controlled soft starting provides for jerk-
free starting of the machine. Due to the low machine star-
ting current a 16 A fuse is adequate.

emperAture dependent oVerloAd protection
For protection against overheating, when a critical tem-
perature is reached the electronic safety feature switches
into the cool-down mode. The machine then continues
to run at a speed of approx: 1100min
constant speed control is deactivated. After a cool-down
time of approx. 10 - 20 s the machine is again ready for
operation. Turn the machine off and back on again to acti-
vate the electronic constant speed control. With the tool at
operating temperature the temperature-dependent over-
load protection reacts correspondingly earlier.

nderVoltAge estArting protection
On short-time failure of the power voltage (plug discon-
nected, instable power mains etc.) the machine will stop.
When the power voltage recovers, the machine must be
turned OFF and back ON again. Then the machine is
ready for operation.

otAtion of geArBox heAd
The gearbox head can be rotated relative to the
stator housing in steps of 90° which enables the
ON/OFF switch to be brought into a more easily
accessible position for special work operations.

Place backing flange on the spindle.
Fit the grinding tool. The raised centering rim of the back-
ing flange must engage exactly in the bore of the grinding
tool.
rinding tools
Use only grinding tools whose admissible maxi-
mum speed is equal to or higher than the no-load
speed of the machine.
Use only clean tools!
