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.
