6.4 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.
6.5 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 11,500 rpm
and a peripheral speed of 80 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.
6.6 OPERATING MODES
6.6.1 Rough grinding
Caution: Use the safety device for
sanding/grinding
(included in items supplied)
.
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.
6.6.2 Cutting
Caution: Use the safety device for abrasive
cutting
(available as accessory, see 8.4)
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.
