8. Maintenance
General rules for all maintenance works:
Pull out mains plug!
Electrical parts to be cleaned without liquids!
Only use original spare parts!
During machine start-up, maintenance works as well as in continuous operation, the
appropriate directions of employer’s liability insurance association on the subject of
accident prevention must be strictly followed.
Please check the connecting cable regularly in view of eventual damage!
We do not accept any liability for damage to persons or machine parts occurred by insufficient
maintenance works or improper greasing.
Please take into consideration that regular and thorough maintenance will increase the lifetime of your
manual welding extruder and avoid unnecessary standstills during production.
For all repairs at the electrical devices please refer to the high-voltage tests as per VDE 0740.
8.1 Cleaning
After 100 service hours or after 3 months at the latest the cooling slots at the motor housing must be
cleaned and the motor blown out with dry compressed air.
8.2 Maintenance works
After 300 service hours or after 6 months at the latest the machine must be thoroughly
cleaned, all gear parts and ball bearings washed with solvents and provided with fresh
grease. The space between inner and outer ring of ball bearings may only be filled with
grease at 1/3 to prevent bearings running hot.
Only use special grease
brand FEIN, Type Sst.I.
After 150 service hours the thrust bearing (item no. 5) of the extruder screw must be
dismounted, cleaned and provided with fresh grease.
For the lubrication of the thrust bearing only use
High temperature grease „Shell“
We recommend further eliminating eventually sticking deposits from the screw, for ex. by means of a
brass brush. When cleaning the screw please take special care not to damage the chrome layer!
Also retighten all screw connections. Missing or faulty parts must be replaced immediately.
Replace carbon brushes not later than when reduced to 7mm length. We recommend to control the
carbon brushes regularly every two weeks, as abrasion of these brushes heavily depends on the
prevailing operating conditions.
After insertion of new brushes it has to be checked whether they can be easily moved in their holding
device.
If, even after insertion of now carbon brushes, a strong sparking occurs within the collector area, the
collector will have to be drawn off. Otherwise there is the danger of heavy wear on the carbon
brushes.
