Long Term Storage - Doosan DL550-5 Operation & Maintenance Manual

LONG TERM STORAGE

When a machine is taken out of service and stored for a time
exceeding thirty (30) days, steps must be taken to protect the
machine. Leaving the machine and work equipment outdoors
exposed to the elements will shorten their 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 waterproof
tarpaulin.
Check that storage site is not subject to flooding or other natural
disasters.
After the machine has been positioned for storage and the
engine stopped, perform the following operations:
Before Storage
Keep the machine in the position to prevent rust of the hydraulic
piston rods.
• Inspect for damaged, loose or missing parts.
• Repaint areas as necessary to prevent oxidation.
• Wash and clean all parts of machine.
• Replace any damaged or missing decals.
• Store the machine in an indoor, stable place. If stored
outside, cover with a waterproof tarp.
• 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 battery from the machine 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
opening to ensure a good seal.
