2. BASIC MAINTENANCE
[1] OIL HANDLING
• Oil is used under extremely harsh conditions (high temperature, high pressure) in the engine
and working device, which causes the oil to undergo deterioration with operating time.
Always use oil that meets requirements such as grade and operating temperature defined in the
operation manual.
Be sure to perform periodic replacement of oil irrespective of contamination in the oil.
• Oil is equivalent to human blood. Exercise due caution when handling oil, keeping impurities
(such as water, metal powder or dust) out of oil. Most of mechanical failures are attributed to
intrusion of impurities.
Extra caution is required to prevent impurities entering during machine storage and lubrication.
• Do not mix oil with another oil of a different grade or brand.
• Oil lubrication must conform to the designated quantity of oil.
Failure to lubricate with an adequate quantity can lead to a machine failure.
• In the event that oil used in the working device turns cloudy, potential intrusion of moisture or
air into the oil may be considered.
Contact us or our sales service agent.
• When replacing oil, always replace the relevant filter as well.
• Do not use any other hydraulic oil that is not recommended by us. Failure to follow the
instruction may cause the filters to get clogged. A small amount of oil remaining in piping and
cylinders does not cause problems even when mixed with other oil.
[2] FUEL HANDLING
CAUTION
For the fuel, be sure to use diesel fuel.
For the engine of this Machine, an electronically controlled high pressure injection unit
is used to obtain good fuel consumption and exhaust gas characteristics.
Since this
unit is of high part precision and lubricating performance, the use of a low viscosity fuel
having a low lubricating characteristic may markedly spoil the durability.
• The fuel pump is a precision part that becomes inoperative if fuel containing moisture or
impurities is used. Extra caution is required to prevent impurities from entering during machine
storage and lubrication.
• Do not remove the strainer when replenishing fuel.
• Always use oil that meets requirements such as grade and operating temperature defined in the
operation manual.
• Ensure that the fuel tank is filled up after finishing the days work to prevent condensation of the
humid air inside the fuel tank that will result in intrusion of moisture.
• Drain deposits and water out of the fuel tank before starting the engine or approximately 10
minutes after fuel replenishment.
• 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.
