PREPARATION FOR STORAGE
For long term idle periods, proper preparation will
pay large dividends in time and money when future
operation of the vehicle is scheduled.
1. Engine should be prepared for storage accord-
ing to instructions found in the engine manufac-
turers manual.
2. The transmission should be prepared for stor-
age. Refer to the instructions in this chapter.
3. The vehicle should be in top operating condition
with all discrepancies corrected. Paint should
be in good condition with no rust or corrosion.
All exposed, machined or unpainted surfaces
should be coated with a good rust preventative
grease.
4. After the vehicle has been parked in its storage
location, all hydraulic cylinders, including Hyd-
rair 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.
5. 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
deterioration.
6. Clean the radiator. Refer to Section C, Cooling
System, for proper cleaning instructions.
7. The cooling system should be completely
drained, chemically flushed, and refilled with a
conditioned water/antifreeze solution suitable
for the lowest temperature anticipated.
A7-4
Refer to Section P, Lubrication and Service, 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.
Never store a vehicle with a dry cooling system.
8. New hydraulic filters should be installed and the
hydraulic tank fully serviced with type C-4 oil as
specified in Section P, Lubrication and Service.
Any operating fluid, such as hydraulic oil, escap-
ing under pressure can have sufficient force to
enter a person's body by pentrating the skin.
Serious injury and possible death may result if
proper medical treatment by a physician familiar
with this injury is not received, immediately.
9. Disconnect batteries, If possible, batteries
should be removed and stored in a battery shop
or a cool dry location on wooden blocks. Do not
store batteries on a concrete floor. Clean bat-
tery compartment, remove all corrosion and
paint compartment with acid proof paint.
10. Wheel axle housings and final drives should be
fully serviced with prescribed lubricants. Seal all
vents.
11. Exhaust openings and air cleaners should be
covered tightly with moisture barrier paper and
sealing tape.
12. All lubrication points (grease fittings) should be
serviced with the prescribed lubricants.
