8.11 MAINTENANCE EVERY 1000 HOURS
Perform this maintenance in tandem with maintenance every 50/100/250/500 hours.
[1] OIL REPLACEMENT IN HYDRAULIC OIL TANK
• All the parts will be at elevated temperatures immediately after engine operation, which urges
you not to replace the filter. Always perform replacement with the engine cold.
• The oil may spout out when the cap of the hydraulic oil tank is removed.
Loosen the bolts so that the cap is raised a little to allow the release of inner pressure, then
remove bolts and remove the cap.
• Securely tighten mounting bolts of the oil filler cap after refilling with the oil. If the mounting
bolts are loose and then filler cap falls during the operation, the hot oil spouts out of the pan,
causing burns. Also, when attaching the oil filler cap, always fit a rubber packing, otherwise,
when the rubber packing is neglected, the hot oil may spout out of the filler cap fitting, causing
burns.
CAUTION
• See “Maintenance 5.1 Use of Lubricating Oil According to Temperature” for which oil to be
used.
• Place the machine in travel position for oil quantity inspection. Oil quantity inspection with the
machine in working position may deceive your eyes to deem the quantity of oil low. Owing to
improper judgment, the oil may be supplied at an excessive amount.
• The engine must be at halt until piping and hydraulic equipment is filled with oil after
replacement of the hydraulic oil filter.
• Avoid that oil exceeds the level point (red point) of the level gauge.
When the oil goes beyond the correct level, it may spout out from the air breather, during
travelling or crane operation.
• Keep impurities out of the filler cap when replenishing oil.
• Refer to “Operation 1.6 Machinery Cover” and remove the machinery cover in accordance with
the instructions in it, when necessary.
• When replacing oil, use a seal tape to the drain cap screw to prevent leakage and then secure
the oil cap tightly.
•
Oil drain pan: A 30-litre container
•
Quantity of oil for replacement: 20 litres

top of the hydraulic oil tank.
4. Place a drain pan directly underneath the drain plug (P) to
receive drained oil.
