7. Maintenance 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 works and the maintenance tools.
7.1. 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.
7.2. Planer
Check the stress of the drive chain in the planer and grease it regularly. Dismount the cover for that
purpose.
Do not 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 function of the safety micro switch.
7.3. Storage
The cylindrical waves of the basic machine are to be kept free from dirtiness and need to be
covered with a thin oil film if they are not being used.
Store dry.
7.4. Used Hydraulic Oil
Only use HLPD 32.
Features: protection against corrosion, resistance to ageing, abrasion-reducing additives, high
carrying capacity and particulary water retending.
The hydraulic oil has to be disposed of properly.
7.5. Checking the Hydraulic Oil-Level
Remove the red screw at the top of the aggregate.
Take out the oil dipstick, clean it and insert it again.
The oil-level must be between the two marks.
