Maintenance / storing / transport
Goal of the chapter is:
Keeping the nominal state and teh operation capacity of the machine.
Effecient planning of the maintenance works and the maintenance tools.
Incrasing the efficiency by avoiding non planned outage.
7.1.
General
Replace damaged parts immediately, be particulary cautions with electrical parts - dirt and
wetness are very good current conductors.
Only use original WIDOS-spare parts.
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.
For machines with a specially high usage percentage the testing cycle should
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.
Check the tightness of loosenend screws.
Scheck the function os safety devices after completion of the maintenance works. Especially
insulation, tension resistance and provtective cables resistance.
7.2.
Clamping elements
For a long service life clean and grease regularly the threaded spindles and the joint parts which
are used for clamping the pipes.
7.3.
Planer
Never lay the planer on its blades.
Check the blades of the planer for sharpness, turn them if necessary (grinded on both sides, max.
thickness of the cuttings: 0.2 mm !).
Check the stress of the drive chain in the planer and grease it regularly. The cover of the planer can
be screwed off for this purpose.
