FULL mark on dipstick.
• Stop engine and wait several minutes before
checking oil level. Remove oil fill cap and dipstick.
• Wipe dipstick clean, insert it into oil fill hole and
tighten securely.
• Remove dipstick and check. If oil is not up to the
FULL mark on dipstick, add oil.
Changing Oil

every 25 hours thereafter.
In order to change the oil, you will have to first drain the
spent engine oil from the engine and then refill with

cap located at the bottom of the recoil starter of the
engine. Catch oil in a suitable container.
• When engine is drained of all oil, replace drain plug
securely.

the oil fill, see Figure 17. Pour fresh oil slowly
through the plug. Replace dipstick.
