2. Mode of Operation
Always make sure the tool is switched off before plugging.
Main voltage must correspond to the operating voltage marked
on the rating plate.
The Angle Grinders for tensions: 105-240 Volts are equipped
with motor protective plugs. When overloaded it disconnects
the machine.
When the motor protective plug is released, it can again be
connected after 20 or 30 seconds .
Switch must be in the "Off" position, before connecting again
the motor protective plug.
To prevent the overbridging of the insulation no additional
marking plates and signs must be riveted or screwed on the
housing. We recommend the use of transfers only.
Only use grinding wheels wit]]. the approved specifications and
for the approved peripheral speed according to the table (see
ulso
§
5).
3. Maintenance and lubrication
Before carrying out any maintenance work always remember
to pull out the plug.
After 100 duty hours clean cool air openings on the motor
housing. Blow out motor with pneumatic air.
After 300 duty hours renew the gear grease. Use only the Fein
special gear grease FG 9. Do not mix with other greases; for
this purpose grease also the anti-friction bearing in the gear
