[3] STOCKING AND STORAGE OF OIL AND FUEL
• Store oil and fuel indoors to keep impurities such as moisture or dust out of them.
• When storing oil and fuel in drums for a long time, line the drums horizontally aligning the drum
bungs below the liquid level (to store them away from moisture). Be sure to cover the drums
with a waterproof sheet if unavoidably storing them outside.
• To prevent deterioration of oil and fuel resulting from long-term storage; employ the first-in
first-out system for using oil and fuel.
[4] GREASE HANDLING
• Grease is designed to prevent the joints from rattling and making noise.
• A nipple that is not described in the Periodic Maintenance chapter is used for overhauls, which
requires no grease replenishment.
Grease the nipple if long-term use hinders its smoothness.
• Thoroughly wipe off old grease squeezed out after greasing.
Extra care is required to wipe a part that the adhesion of sands and dust accelerates the
wearing away of the rotating part.
[5] FILTER HANDLING
• A filter is an extremely important part that keeps major equipment free from impurities in oil,
fuel, and the air circuit, which prevents an associated failure. Periodic replacement of the filter
is required in accordance with the Operation Manual.
The replacement period should be shortened if commensurate with harsh operating
environments or the amount of oil and fuel (containing sulfur) used.
• Do not reuse any washed filters (cartridge-typed ones) under any circumstances.
• After replacing an oil filter, check the used filter for any metal powder.
If metal powder is found on the used filter, contact us or our sales service agent.
• Always unpack the replacement filter prior to its use.
• Always use Maeda genuine filters.
[6] COOLANT HANDLING
• The river water contains a large amount of calcium and impurities. Use of the river water results
in accumulation of water stain in the engine and radiator, which causes heat exchange error
leading to overheating.
Do not use non-drinkable water.
• Always use antifreeze following precautions stated in the Operation Manual.
• Keep antifreeze from flame. Antifreeze is a flammable solution.
• The mixing proportion of antifreeze varies with outside air temperature.
For the mixing proportion, refer to the descriptions under "Maintenance 10.3 IRREGULAR
MAINTENANCE [4] CLEANING ENGINE COOLING SYSTEM".
• In the event of overheating, replenish coolant with the engine cold.
• Shortage of the coolant may cause overheating and corrosion of the radiator attributed to air in
the system.
