4. Motor and rotor
The carbon dust accumulated in the motor and brush housing should be removed every 100 hours.
The motor's rotor should be permanently clean with a uniform surface (light bronze colour).
5. Gear box
Change grease every 500 operating hours. After dismounting the machine, oil all mechanisms to
eliminate old grease. Remove parts with dry compressed air and apply new grease with clean hands.
Do not use any dissolvents. Approximately 300 grs. of grease is needed for a correct lubrication. An
excessive amount of grease is not recommended as it can increase the temperature of the machine.
Grease type: LGMT2 by SKF or similar. We recommend that this operation be carried out by an
authorized after-sales service.
6. Dismounting the gear box
Before dismounting the cover of the gear box, never introduce sharp objects such as tips, screwdrives,
etc. between the body and cover's connecting faces. The correct procedure is to tap the front of the
octagon gently with a plastic hammer.
7. Machine maintenance and repair should be done by a specialist
All repairs should be carried out by a specialist and only original parts should be used.
