8.4 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.
8.5 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 12000 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.
