5. LUBRICATING OIL

5.1 USE OF LUBRICATING OIL ACCORDING TO TEMPERATURES

Use of lubricating oil should vary with changes in temperature.

• A specified oil quantity is defined as a total quantity of oil including that for unit piping, and a replacement oil quantity is defined as a quantity of oil to be replaced at inspection and maintenance.

• Always use SAE15W-40SE or SAE10W-30SE to start the engine with temperature at 0°C or below despite rise in day time temperatures of approx. 10°C.

• Be sure to use our recommended abrasion-resistant hydraulic oil for the hydraulic oil system; ISO VG46 and VG32.

”Nippon Oil Super Highland 32” is adopted for a hydraulic oil system as factory default.

• Be careful not to refuel too much, otherwise, fuel may flood when the machine travels on a slope.

Caution

• Molybdenum disulfide filled grease is to be applied to the boom slide plate (top), both sides and bottom of the boom.

• Do not apply molybdenum disulfide filled grease to the slewing bearing.
