2. BASIC MAINTENANCE
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 to handle 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 other oil of different grade or brand.
• Oil lubrication must conform to the designated quantity of oil.
Failure to lubricate at 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 become clogged. A small amount of oil remaining in piping and cylinders does not
cause problems even when mixed with other oil.
FUEL HANDLING
CAUTION
Always use diesel fuel of the following conditions for the fuel.
• The cetane number of the fuel must be 45 or higher.
• The sulfur content must be less than 1,000 ppm of the total volume (recommended 500 ppm).
For the engine of this machine, a high pressure injection unit is adopted to obtain good fuel
consumption and exhaust gas characteristics. Since this unit is required to have high part
precision and lubricating performance, the use of a low viscosity fuel having a low lubricating
characteristic may markedly spoil the durability.
Up to B7 can be used for biofuels.
• The fuel pump is precision equipment 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 daily 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.
