6.4 Changing the grinding wheels (Fig. 5 / 6)
Use the face spanner (5) supplied to change the 
grinding wheels. The face spanner (5) is stored in 
the additional handle (3). Pull the face spanner (5) 
out of the additional handle (3) when you need it.
Danger!  For safety reasons, the angle grinder 
must not be operated with the face spanner (5) 
inserted in it.
Warning! 
• 
Simple wheel change by spindle lock:
• 
Press the spindle lock and allow the grinding 
wheel to latch in place.
• 
Open the flange nut with the face spanner. 
(Fig. 6)
• 
Change the grinding or cutting wheel and 
tighten the flange nut with the face spanner.
Notice!
Only ever press the spindle lock when the 
motor and grinding spindle are at a stand-
still! You must keep the spindle lock pressed 
while you change the wheel!
For grinding or cutting wheels up to approx. 3 mm 
thick, screw on the fl ange nut with the fl at side 
facing the grinding or cutting wheel.

6.6 Motor
It is vital for the motor to be well ventilated during 
operation. Be sure, therefore, to keep the ventilati-
on holes clean at all times.
6.7 Grinding Wheels
• 
Never use a grinding or cutting wheel bigger 
than the specified diameter.
• 
Before using a grinding or cutting wheel, 
check its rated speed. 
• 
The maximum speed of the grinding or cut-
ting wheel used must be higher than the idle 
speed of the angle grinder.
• 
Use only grinding and cutting wheels that are 
approved for a minimum speed of 8,500 rpm 
and a peripheral speed of 52 m/sec.
• 
Check the direction of rotation when you use 
diamond cutting wheels. The directional arrow 
on the diamond cutting wheel must point in 
the direction in which the tool rotates.
Take special care that the grinding/sanding 
wheels are properly stored and transported. 
Ensure that the grinding/sanding wheels are 
never exposed to shock, jolts or sharp edges (for 
example during transport or storage in a toolbox). 
This could cause damage (such as cracks) to the 
grinding/sanding wheels and place the user in 
serious danger.
