• Do not use any fuel stored in a drum can and such for a long period of time.
• Use only the fuel purchased from the authorized dealers.
[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 sideways (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 resulted from long-term storage; employ the first-in
first-out 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 a long-term use hinders its smoothness.
• 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 in responses to harsh operating environments or
the amount of oil 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 overheat.
Do not use non-potable 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.
See “Maintenance 8.11 Every 1000 Hours Maintenance [2] Cleaning Engine Cooling System”
for the mixing proportions.
• In the event of overheating, replenish coolant with the engine cold.
• The machine low in coolant may cause overheating and corrosion attributed to aeration.
• Use the lubricant compliant to one of the SAE J814, SAE J1034, ASTM D3306 or JIS K2234
standard.
• LLC (Long Life Coolant) must be mixed with soft water.
• The concentration of LLC should be 30 – 60 %.
