5.5 Maintenance
5.5.1 Change engine oil
[At 250 hours for the first change and every 500 hours thereafter]
When checking, replenishing, and draining the engine oil, be sure
to wait 10 to 20 minutes after engine stops until it cools down.
Engine oil is very hot and highly pressurized during or just after the
operation. Hot oil could blow out and can cause injury.

① Loosen the drain plug“1” located outside the frame to drain the oil. Open the drain valve“2”
provided inside the machine to drain condensate.
② After finishing drainage, close the drain valve “2”securely and install the plug“1”and supply
engine oil through oil filler port“3”. [Oil supply: about 22.5gal.]
③ After finishing the oil supply, tighten the cap of oil filter port“3”firmly.
