Checking Oil Level
Before operating the snow thrower, check the oil level.
•With engine on level ground, the oil must be to 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 fresh oil.
•Drain oil while engine is warm. Remove oil drain cap located at the bottom of the recoil starter of the engine. Catch oil in a suitable container.

•Remove and inspect the spark plug.
•Replace the spark plug if electrodes are pitted, burned, or the porcelain is cracked. See Figure 21.
