MAINTENANCE
9VX3
1. Keep sand and dust out of the hydraulic system
by keeping the reservoir filler cap tight and
servicing the hydraulic system filters frequently.
2. The fuel system should be kept free of sand and
dust by keeping the tank filler cap tight and
servicing the fuel filters frequently.
3. The engine breathers and air cleaner should
also be serviced frequently to prevent sand and
dust from entering the engine. The engine oil
and oil filter should be changed at shorter than
normal intervals to ensure a clean oil supply to
the engine's moving parts.
4. When lubricating the machine, thoroughly clean
each grease fitting before attaching the grease
gun. Pump generous amounts of grease into all
lubrication points, using the fresh grease to
pump out old.
5. Adequate ground bearing support may be
required for the tracks when operating in soft
sand. Be alert for signs of track digging into sand
during operations. It may be necessary to back
off and fill in area where tracks dig in.
The increased frequency of lubrication and
service discussed above should be determined
by observations made at the work site.
Inspection will determine how long it takes for
lubricants, breathers and filters to accumulate
unacceptable amounts of sand or dust. The
frequency of lubrication and service should be
adjusted accordingly.
■ High Humidity or Saltwater
In some locations, such as coastal areas, the
machine may be exposed to the deteriorating effects
of salt, moisture, or both. To protect exposed
metallic surfaces, wiring, paint and other items, keep
them dry and well lubricated where salt or high
humidity are encountered. Follow the
recommendations below when operating in these
conditions.
1. Make frequent inspections for rust and
corrosions and remove them as soon as they
are detected. Dry and paint exposed surfaces
after rust and corrosion have been removed.
2. W here paint may not be applied, such as on
polished or machined surfaces. Coat the area
with grease or lubricant to repel water.
3. Keep bearings and their surrounding surfaces
well lubricated to prevent the entry of water.
4. Never use saltwater in the cooling system.
Internal corrosion will occur and all parts will
have to be replaced.
5. Hose down the machine periodically when
working in saltwater. If necessary, use an oil
soaked cloth to clean moving parts.
6
. If the machine is submerged, be sure it is never
submerged in water deeper than upper crawler
belt.
If the machine exceeds this limit, disassemble,
clean and lubricate the lower.
■ High Altitudes
Variations in altitude alter the fuel-air mixture burned
in the engine and affect the engine's performance.
At high altitudes. Atm ospheric pressures are lower
and less oxygen is available for combustion of the
fuel. Above 1500 meter, the engine fuel setting may
have to be changed to ensure proper performance.
Consult engine manufacturer should this problem
answer.
Keeping the air cleaner clean and free of
obstructions will help alleviate high altitude problems.
At high altitudes, closely monitor the engine
temperature for overheating.
