Maintenance
General It is recommended that maintenance be performed on the machine at regular intervals or when the
carbon brushes switch off at the latest.
Cleaning Clean all parts – with the exception of the electrical parts – with cold cleaning agent. Caution! No
cleaning agent should penetrate into the bearing. Clean the electrical parts with a dry brush.
Check for wear Check the disassembled parts for wear (visual inspection) and replace worn parts.
Electrical tests Before reassembling, perform an electrical test on all relevant parts (see chapter Electrical and
Mechanical Test Instructions).
Lubrication Each time maintenance is performed, the machine is to be lubricates as stated in the lubrication plan.
After the machine is fully disassembled, completely remove the old grease and replace with new
grease. The grease must be applied to the machine as indicated in the lubrication plan.
Legend
Distribute the grease type N (125 g) from the maintenance set as follows:
A Thinly daub
BGenerously cover
CFill with 43 g grease
DFill with 28 g grease
Torques Screws in plastic 1.8 Nm
Screws in metal 4.0 Nm
Gear box screws 15.0 Nm
■Use locking agent for all metal housing screws!
