5.2 Setting the guard (Fig. 3)
Warning!
• 
  Switch off the tool. Pull the power plug.
• 
Adjust the guard (4) to protect your hands 
so that the material being ground is directed 
away from your body.
• 
The position of the guard (4) can be adjusted 
to any specific working conditions. Undo the 
screw (a) and turn the cover (4) into the requi-
red position.
• 
Ensure that the guard (4) correctly covers the 
gear wheel casing.
• 
Retighten the screw (a).
• 
Ensure that the guard (4) is secure.
 Take care that the safety device is secure.
 Never use the angle grinder without the 
guard.
5.3 Test run for new grinding Wheels
Allow the right-angle grinder to run in idle for at 
least 1 minute with the grinding or cutting wheel 
fi tted in place. Vibrating wheels are to be replaced 
immediately.
6. Operation
6.1 Switch (Fig. 4)
  The angle grinder comes with a safety switch 
which is designed to prevent accidents. To switch 
on, push the slide switch (a) to the right while at 
the same time pushing the ON/OFF switch (2) 
forwards and depressing. To switch off  the angle 
grinder, depress the button (2) at the back. The 
switch (2) will jump back into its starting position.
 Wait until the machine has reached its top 
speed. You can then position the angle grin-
