IMPORTANT: Only ever press the spindle lock when the motor and grinding
spindle are at standstill. The spindle lock must be kept pressed while the wheel
is changed.
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 angle grinder to run in idle for at least 1 minute with the grinding or cutting wheel fitted in
place. Vibrating wheel must be replaced immediately.
Motor
It is vital for the motor to be well ventilated during operation. Ensure that the ventilation holes a re
clean and unobtrusive at all times.
carbon brushes
Carbon brushes that are broken, burned, or shorter than 5 mm are to be replaced using the same
spec brushes. Always replace brushes in pairs.
Grinding wheels
Never use the grinding or cutting wheel bigger than the specified diameter. Before using the a
grinding or cutting wheel, check its rated speed. The wheel’s rated speed must be higher than the
idle speed of the grinder.
Use only grinding and cutting wheels that are approved for a maximum 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
work piece surface and guide back and forth over the work piece in steady movements.
cutting:
When you use the 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 asbestos materials.
Never use a cutting wheel for rough grinding.
Overload
The motor of your right angle grinding machine may be damaged when overloaded. This results
from excessive working pressure over a prolonged period Therefore you should not try to accelerate
your working speed by increasing pressure on your machine. The abrasive disks work more
efficiently if only slight pressure is exerted on the grinding machine, thus avoiding a drop in the
grinding speed.
Maintenance
• The protective cover, air slits and motor housing should be kept as free of dirt and dust as
possible.
• Rub off the device with a clean cloth or use compressed air at a low pressure to blowout any dust
or dirt. Excessive amounts of metal dust may result in electricity from the internal components
being conducted on to exposed metal parts!
• Do not subject the grinding machine to any overload! Overloading will lead to a reduction in the
speed and performance and cause the machine to overheat! If this should happen, switch the
grinding machine off and let it cool down for approximately 30 minutes or to room temperature!
NOTE: Turning off the grinding machine while it is being subjected to a load will reduce the working
life of the operating switch!
