5. The vehicle engine should be inspected and serv-
iced according to the Engine Manufacturer's Op-
eration And Maintenance Manuals.

eign materials. If water entry is suspected, dis-
connect air tubes at the turbochargers to check
for water damage before attempting startup.

for engine priming.
Have a new safety filter (secondary) filter element
on hand before removing old one. Do not keep
intake system open to atmosphere any longer than
absolutely necessary.
c. Remove and replace both the primary and
safety filter (secondary) elements in the air
cleaners. Check all intake lines between air
cleaners and engine. All clamps must be tight.
Indicating plunger in filter condition indicators
must be free.
d. The tubes in precleaner section of air cleaner
assembly should be inspected, all tubes should
be clear and clean. Use a light to inspect the
tubes. The light should be visible. If clogging is
evident, precleaner must be cleaned. Clean
precleaner according to instructions in Section
"C", of the Komatsu

coolant and inhibitors after checking all lines,
hoses and connections. Refer to Section "P",

Storage Procedures
6. If fuel was left in the tanks, it must be removed. Do
not attempt to use old diesel fuel.
a. With tanks empty, remove inspection plates
and thoroughly check interior of tanks; clean if
necessary to remove sediment and contamina-
tion. If fuel was contaminated, lines should be
disconnected and blown clear.
b. Check all fuel lines for deterioration or damage.
Replace lines as necessary.
c. Replace inspection covers, use new gaskets.
d. Service tanks with specified diesel fuel.
e. Replace fuel filters.
Any operating fluid, such as hydraulic oil or brake
fluid escaping under pressure, can have sufficient
force to enter a person's body by penetrating the
skin. Serious injury and possible death may result
if proper medical treatment by a physican familiar
with this injury is not received immediately.
7. Hydraulic tank should be drained. If oil is not
contaminated and is stored in clean containers, it
may be reused if filtered through 3-micron filter
elements when being pumped back into the tank.
Do not attempt to use contaminated hydraulic oil,
especially if water entry into the system is sus-
pected.
NOTE: If filling is required, use clean hydraulic oil only.
Refer to the Lubrication chart in Section "P", Lubrica-
tion and Service, for proper oil specifications.
a. Replace hydraulic filter elements and clean
suction strainer elements. While suction strain-
ers are removed, inspect and clean interior of
tank thoroughly to remove all sediment and
foreign material.
b. Inspect all hydraulic lines for deterioration or
damage. Replace suspected lines - don't risk
hose ruptures or blow outs.
c. Check hydraulic components (pumps, valves
and cylinders) for damage and corrosion. Se-
cure all mountings and connections. Control
valves must be free moving with no binding.
