7. Maintenance and repair
Goal of the chapter is to:
• keep the nominal condition and the operation capacity of the machine.
• increase the efficiency by avoiding non-planned outage.
• Efficient planning of the maintenance works and the maintenance tools
7.1. Maintenance, Inspection and repair
All maintenance and repair works have to be basically performed with the
machine in off position.
During this the machine has to be secured against unauthorized switching on.
Prescribed maintenance and inspection works should be performed in time. The
DVS gives the advice of inspection works after 1 year.
Should for machines with a specially high usage percentage the testing cycle be
shortened .
The works should be performed at the WIDOS GmbH company or by an
authorized partner.
The linear guides for heating element and planer must be cleaned every week
e.g. with a brush.
Check the linear guide carriages every 3 months and grease them over the
lubricating nipple if necessary. Chips or other impurities in the guides can be the
cause if the heating element or the planer jam or run heavily.
• Clean the piston rods every month with an oily tissue.
• Check the hydraulic connections every month for tightness, tighten again if necessary.
• The operating staff has to be informed before the starting of the maintenance works.
• Check the tightness of loosened screws.
• Check the function of the safety devices after completion of the maintenance works.
Especially insulation, tension resistence and protective cables resistence.
7.2. Planer
• Check the driving chain in the planer from time to time and lubricate it. For that purpose
screw off the housing of the planer.
• Check the cutting ability of the planer, exchange it if necessary (double sided polished
section, max. chip thickness = 0,2 mm!)
