Always pull the plug out of the power socket
before carrying out any work on the machine, before changing the grinding tool and in periods of non-use.
Always run the power cable away from the back of
the machine to guard it from damage.
For outdoors work use only suitably approved
extension cables with a minimum conductor cross section of 1.5 mm
2
. The plug connectors must
have earthing contacts and be rain-water-proof.
Keep the machine in a safe place and out of the
reach of children.
Always wear goggles, safety gloves and ear muffs
when using the machine for grinding, brushing and cutting purposes. Wear a breathing mask on dusty jobs.
For safety reasons the right-angle grinder is only

Operating instructions for right-angle grinders
The machine is light, handy, totally insulated and designed in compliance with the international specifications CEE 20. Provided it is serviced as described in these instructions, the machine will serve you for a long time.
VOLTAGE
Before you use the machine for the first time, check that the voltage marked on the rating plate is the same as your mains voltage. Under no circumstances is the mains voltage to differ from the rated voltage by more than 10%.
SWITCH
To help prevent accidents, the right-angle grinder is equipped with a safety switch. To turn on the machine, push the switch forward and push down until it latches in place. To turn the right-angle grinder off, push the switch down. It will then jump back to its original position.
REPLACING THE GRINDING WHEEL Pull out the power plug.
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. Change the grinding or cutting wheel and tighten the flange nut with the face spanner.
Important! Only ever press the spindle lock
when the motor and grinding
spindle are at a standstill! 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 flange nut with the flat side facing the grinding or cutting wheel.
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 fitted in place. Vibrating wheels are to be replaced immediately.
MOTOR
It is vital for the motor to be well ventilated during operation. Be sure, therefore, to keep the ventilation holes clean at all times.
CARBON BRUSHES
Carbon brushes that are burned, broken or shorter than 5 mm are to be replaced by original replacement brushes. Always replace the carbon brushes in pairs.
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 wheel´s rated speed must be higher than the idle speed of the right-angle grinder.
Use only grinding and cutting wheels that are approved for a minimum speed of 11,000 rpm and a peripheral speed of 80 m/sec.
OPERATING MODES Rough grinding:
For the best rough grinding results, hold the grinding wheel at an angle of between 30° and 40° to the workpiece surface and guide back and forth over the workpiece in steady movements.
Cutting:
When you use the right-angle grinder for cutting purposes, avoid tilting it in the cutting plane. The cutting wheel must have a clean cutting edge. A diamond cutting wheel is best used to cut hard stone.
It is prohibited to use the machine on asbestos materials!
Never use a cutting wheel for rough grinding.
