8.8 MAINTENANCE EVERY 250 HOURS
Perform this maintenance in tandem with maintenance every 30/50 hours.
[1] REPLACEMENT ENGINE LUBRICATING OIL AND OIL FILTER CARTRIDGE
• The drain plug of the engine oil pan is located directly underneath the machine.
Place the outriggers and raise the machine 50mm from the ground for draining engine oil.
Insert square timbers between both rubber track and the ground to gain stability for safety
assurance.
• Make sure the oil level gauge is secured properly after inspection and replenishment of the oil.
Potential fall of the oil level gauge during operation may occur if disregarded, which could
cause boiling oil to gush that results in burns.
• All the parts will be at elevated temperatures immediately after engine operation, which urges
you not to replace oil and the filter cartridge.
Always perform replacement with the engine cold to touch.
CAUTION
• Ensure that no old gasket adheres to the filter stand. Potential oil leak may occur if old gasket
remains on the stand.
• Be sure to use oil specified in section 5.1 “Use of Lubricating Oil according to Temperatures”
in Inspection and Maintenance. Failure to use proper oil may cause the engine to shorten its
useful life. Always use the specified oil for replenishment.
• The engine oil must be maintained at a proper amount.
• The complete draining of oil is disabled if the engine becomes cold completely. Oil draining is
allowed when the engine is cold to touch.
• Keep impurities out of the filler cap when replenishing oil.
• Oil drain pan: An 8-liter container
• Quantity of oil for replacement: 3.1L
1. Place the machine on a level surface.
2. See “Operation 2.14 Outrigger Setting Operation” to set the
outriggers and raise the rubber track for about 50mm from the
ground.
Check the following before crawling under the machine:
• Ensure that the outriggers are extended at the maximum.
• Visually check the level to make sure the machine in a
horizontal position.
• Insert solid blocks between the crawler and the ground to
keep the machine raised.
3. Crawl under the machine and place a drain pan directly
underneath the drain plug (P) at the bottom of the engine oil pan
to receive drained oil.
