Long Term Storage - Doosan DX700LC Operation And Maintenance Manual

LONG TERM STORAGE

When a machine is taken out of service and stored for a time
exceeding 30 days, steps must be taken to protect the machine.
Leaving equipment outdoors exposed to the elements will
shorten its life.
An enclosure will protect the machine from rapid temperature
changes and lessen the amount of condensation that forms in
hydraulic components, engine, fuel tank, etc. If it is not possible
to put the machine in an enclosure, cover it with a tarpaulin.
Check that the storage site is not subject to flooding or other
natural disasters.
After the machine has been positioned for storage and the
engine shut down, perform the following operations:
Before Storage
Keep the excavator in the position shown in Figure 92 to prevent
rust of the hydraulic piston rods.
• Inspect for damaged, loose or missing parts.
• Repaint necessary area to prevent oxidation.
• Wash and clean all parts of machine.
• Store the machine indoor, stable place. If stored
outside, cover with a waterproof tarpaulin.
• Perform lubrication procedures on all grease points.
• Apply a coating of light oil to the exposed plated
metal surfaces (such as hydraulic cylinder rods, etc.)
and to all the control linkage and control cylinders.
(Control valve spools, etc.)
• Remove the battery from the excavator to be fully
charged and stored.
• Inspect the coolant recovery tank and radiator to
make sure the antifreeze level in the system is
correct. Make sure that antifreeze concentration is
enough for the lowest temperature anticipated during
storage.
• Seal all external openings (i.e. engine exhaust outlet,
crankcase and hydraulic breather, fuel vent line, etc.)
with tape wide enough to cover the opening,
regardless of size.
NOTE:
When sealing with tape, be sure to extend
tape approximately one inch (25 mm)
beyond opening to insure a good seal.
