Preparation For Storage - Komatsu 930E-2 Shop Manual

For long term idle periods, proper preparation will pay
large dividends in time and money when future opera-
tion of the vehicle is scheduled.
1. Engine should be prepared for storage according
to instructions found in the engine manufacturer's
manual.
2. The vehicle should be in top operating condition
with all discrepancies corrected. Paint should be
in good condition, no rust or corrosion, all ex-
posed, machined or unpainted surfaces should
be coated with a good rust preventative grease.
3. After the vehicle has been parked in its storage
location, all hydraulic cylinders, including Hydrair
suspensions, should be retracted as much as
possible (steering cylinders centered). Wipe the
exposed portion of all cylinder rams clean and,
coat (including seals on ends of barrel) with good
preservative grease.
4. If long term storage is anticipated, the vehicle
should be blocked up with the tires clear of the
ground or floor to remove vehicle weight from the
tires. Lower air pressure in the tires to 15-25 psi
(103-172 kPa). Completely cover the tires with
tarpolins to minimize rubber oxidation and dete-
rioration.
5. Clean the radiator; refer to Engine Service Manual
and the Vehicle Service Manual for the proper
cleaning instructions.
6. The cooling system should be completely drained,
chemically flushed, and refilled with a conditioned
water/antifreeze solution suitable for the lowest
temperature anticipated.
Refer to Section "P", Fluid Specifications and
Charts, for the proper anti-freeze and conditioner
concentrations. After refilling the system, always
operate the engine until the thermostats open to
circulate the solution through the cooling system.
NOTE: NEVER store a vehicle with a dry cooling sys-
tem.
