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
Change engine oil after first two hours of operation and
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.
• Remove the dipstick from the oil fill. For location of
the oil fill, see Figure 17. Pour fresh oil slowly
through the plug. Replace dipstick.

• Remove and inspect the spark plug.
• Replace the spark plug if electrodes are pitted,
burned, or the porcelain is cracked. See Figure 25 .
• Clean the spark plug and reset the gap to 0.030" at
least once a season or every 50 hours of operation.
See Figure 25 .
• Spark plug replacement is recommended at the
start of each season. Refer to engine parts list for
