5.5 Maintenance
5.5.1 Change Engine Oil
At 50 hours for the first change and every 500 hours thereafter
Caution in filling or draining engine oil
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.
Viscosity of engine oil greatly affects startability, performance, oil consumption of the engine, as well
as wear of the moving parts.
Choose appropriate oil based upon the table below according to the outside air temperature.
Relation between viscosity (SAE) and temperature
SAE Viscosity number Temperature
10W
−22°F to 50°F (−30℃ to 10℃)
30
14°F to 104°F (−10℃ to 40℃)
40
32°F to 122°F (0℃ to 50℃)
15W/40
−4°F to 104°F (−20℃ to 40℃)
Be sure to use CD class engine oil or superior class. (Using engine oil with poor quality may shorten the
life of the engine).
When two or more different brands of oil are mixed, its performance can be deteriorated.
Do not mix oils.
(Procedure)
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”.
③ After finishing the oil supply, tighten the cap of oil filter
port“3”firmly.
