• The air should be released from the circuit when the machine runs out of fuel or when the fuel filter is
replaced.
• Clean the tank and fuel system if any foreign substances enter the fuel tank.
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 resulted from long-term storage; employ the first-in first-out for
using oil and fuel.
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.
• 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.
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 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.
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.
