SANDY OR DUSTY WORK SITES.
The presence of large amounts of sand or dust at the work site can contribute to accelerated component weather. Either
substance win act as an abrasive when deposited on moving parts of the machine.
This problem can be alleviated by increasing the schedule of lubrication and by servicing breathers and fillers at more
frequent intervals. Follow the recommendations below when operating in sand or dust on a regular bases.
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 aII 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.
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.
