III. PRE-OPERATE INSPECTION
1.Engine Oil
Engine oil is a key factor in deciding the engine’s performance. Do not
apply engine oil with additives or 2-stroke gasoline engine oil, because
they haven’t enough lubrication, and may shorten the engines service life.
Check the engine with it stopped on a level ground.
Engine oil capacity: 125-S/145-S/170-S 0.3L~0.5L
Engine oil recommended: SAE15W-40
As viscosity varies with regions and temperatures, SJ class oil is
recommended.
Check method:
1) Remove the dipstick and clean it.
2) Reinsert the dipstick into the oil Filling hole without screwing it, and
check oil level.
3) If the oil level is too low, add the recommended engine oil up to the
oil upper level.
4) Reinstall the dipstick.
