MAINTENANCE
17VX3
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.
UNUSUAL
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.
Where 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. Atmospheric 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.
