Immobilization
7.9.1
Preservation (temporary immobilization )
7.9.2
During immobilization
When the machine is out of use for 6 months, after
this time all assemblies must be brought to operating
temperature and maneuvered for
approx. 15 minutes.
Beforehand, the anti-corrosion coat must be
removed from the piston rods, and the openings of
the air filter system and the exhaust pipe freed.
After the maneuvering cycle, preserve the machine
once more as previously described.
7.9.3
After immobilization
Before putting the machine into operation once
more, the following measures must be carried out:
• Anti-corrosion coat must be cleaned from the
piston rods.
• Seal off the air intake opening of the air filter and
the exhaust pipe opening.
• Check the condition of the air filter main cartridge
and the safety cartridge and replace if necessary.
• Clean the machine with a neutral detergent.
• Check and, where required, re-charge and re-
install the battery.
• Carry out all measures for putting the diesel
engine back into operation listed in the Engine
Operating Manual.
• Lubricate the machine according to the
lubrication plan.
If the machine has been out of use for more than
6 months
– The oil in the assemblies such as axles,
transmission(s), etc. must be changed.
– Replace hydraulic oil filters (suction and return
filters, breathers, if installed).
Machine damage
due to damage from storage (e.g. corrosion
damage) during shutdown periods over three
months.
• Perform the preservation measures.
Preservation measures:
• We recommend keeping the machine in a dry,
dust-free room during the storage period.
• Thoroughly clean the inside and outside of the
machine, including the engine.
• Lubricate the machine according to the
lubrication plan.
• Check the oil levels of all assemblies such as
transmission(s), etc. and top up if necessary.
• Check the hydraulic oil level and top up if
necessary.
• Repair any paint damage.
• Fill the diesel tank completely, to prevent
corrosion of the tank walls.
• Check the antifreeze level in the coolant and
adjust if necessary.
• Perform all preservation measures specified in
the diesel engine Operating Manual.
• Ensure that the crawler chain tension
corresponds to the prescribed value and protect
rubber crawler chains from direct sunlight.
• Treat bare piston rods with a commercially
available anti-corrosion agent.
• Remove and clean the battery and keep it
according to regulations in a dry - in winter, frost-
proof - room. Coat connections with a little pole
grease.
• Seal off the air intake opening of the air filter
system and the exhaust pipe opening.
