[3] STOCKING AND STORAGE OF OIL AND FUEL
• Stock and store oil and fuel indoors to keep impurities such as moisture or dust out of them.
• For lengthy storage of a drum, it should be laid down so that its tap is below the surface of fuel (to prevent
moisture entering). Be sure to cover the drums with a waterproof sheet if 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 joint from rattling and making noise.
• Any nipple that is not described in the Periodic Maintenance chapter is used for overhauls, which
requires no grease replenishment. Only grease the nipple if 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 will accelerate 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 for the oil and fuel (sulfur content) used.
• Do not reuse any washed filter s (cartridge type one) under any circumstances.
• After replacing an oil filter, check the used filter for any metal powder. If check finds metal powder on the
used filter, contact us or our sales service agency.
• As to a replacement filter, always unpack it immediately prior to its use.
• Always use Maeda genuine filters.
[6] COOLANT HANDLING
• River water contains a large amount of calcium and impurities. Use of the river water results in
accumulation of water sludge in the engine and radiator, which causes heat exchange error leading to
overheating. Do not use any impure water.
• Always use antifreeze following precautions stated in the Operation Manual.
• Keep antifreeze away from flames. Antifreeze is a flammable solution.
• The mixing proportion of antifreeze varies with outside air temperature. See “Maintenance 10.10 Every
1000 Hours [2] Cleaning engine cooling system” for the mixing proportions.
• In the event of overheating, replenish coolant with the engine cold.
• A machine low in coolant may cause overheating and corrosion attributed to aeration.
[7] ELECTRICAL PART HANDLING
• The electrical parts are susceptible to water damage and damaged coating. A current leakage is
developed if the electrical parts are wet or have damaged coating, which causes the machine to go out of
order and malfunction. Exercise due caution for handling the electrical parts.
• Inspection and maintenance include the checking of belt tension, belt damage, and battery fluid level.
• Never remove and disassemble equipment (electrical parts) from the machine.
• Only optional electrical parts that accompany the machine can be installed.
• Keep the electrical parts away from water when the machine is washed and used in the rain.
• When using the machine at the seashore, keep the electrical parts free of water and impurities to prevent
corrosion.
