5.5 Maintenance
5.5.1 Change engine oil
[At 50 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.

Never supply more engine oil than the proper level. Too much oil
could cause white smoke out of the exhaust, and it can cause
damage and accident to engine.
<Procedure>
① Remove the drain plug“1”attached outside the
plane, open a drain valve“2”inside the plane, and
discharge engine oil drain.
② When the oil is completely drained, close a drain
valve“2”after attaching a drain plug “1”, remove
the cap of an engine oil filler port“3”, refill new
engine oil. [Oil supply: about 3.4gal. (13.2 L)]
③ After finishing the oil supply, tighten the cap of oil
filter port“3”firmly.
④ Please be sure to check whether engine oil is
normal oil supply with an oil level gauge before
operating this machine.
