8. Maintenance, care and repair
Goal of the chapter is:
Keeping the nominal state and the operation capacity of the machine.
Increasing the efficiency by avoiding non-planned outage.
Efficient planning of the maintenance work and the maintenance tools.
8.1. Maintenance and inspection, repair
All maintenance and repair work 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 work should be performed in time.
The DVS gives the advice of inspection work after 1 year.
For machines with a specially high usage percentage the testing cycle should be
shortened.
The work should be performed at the WIDOS GmbH company or by an
authorized partner.
Take care that:
- You do not step on any surface marked by this symbol while working within the
machine,
- You do not step onto lines and motion elements.
Inform the operating personnel before the beginning of any maintenance and repair work.
Generally care for cleanness!
Handle the machine with care.
Immediately replace damaged parts, take special care at electric parts.
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.
System parts and pressure hoses should be depressurized before the beginning
of any repair work.
Even if the machine is switched off, pressure may be in the hydraulic
accumulator!
There is a danger of injuring the eyes by hydraulic oil squirting out.
Make a visual inspection of the hydraulic hoses before each work beginning.
The hydraulic oil is inedible!
Damaged hydraulic hoses have to be replaced immediately.
Completely renew the hydraulic hoses every 5 years.
Clean the piston rods
weekly
using an oil-bearing cloth.
Check the hydraulic connectors
weekly
on their leak tightness and retighten them if
necessary.
Do control all screwed connections if being tight.
