SAE viscosity grade according to the expected
operating temperature.

Viscosity Chart

NOTE:

Although multi-viscosity oils (5W30, 10W30

etc.) improve starting in cold weather, these multi­

viscosity oils will result in increased oil consumption

when used above 32° F. Check your snow thrower’s

engine oii level more frequently to avoid possible

engine damage from running low on oil.

Refer to the viscosity chart for proper selection of

engine oil.

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 5W30 oil.

Changing Oi!

Change engine oil after the first two hours of
operation and every 25 hours thereafter.

In order to do that you will have to first drain the spent
engine oii 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.

When engine is drained of all oil, replace drain
plug securely.

Remove the dipstick from the oil fill plug. For

location of the oil fill plug, see Figure 17. Pour

fresh oil slowly through the plug. Replace

dipstick.

Check and make sure that the level of oil is up to

the FULL mark on the dipstick.

A

WARNING:

Temperature of muffler and

nearby areas

may exceed 150° F(65°C).

Avoid these areas.

Spark Plug

Clean area around the spark plug base.

Remove and inspect the spark plug.

Replace the spark plug if electrodes are pitted,

burned, or the porcelain is cracked. See Figure 19.

Clean the spark plug and reset the gap to 0.030"
at least once a season or every 50 hours of

operation. See Figure 19.

Spark plug replacement is recommended at the
start of each season. Refer to engine parts list

for correct spark plug type.

NOTE:

Do not sandblast spark plug. Sparkplug

should be cleaned by scraping or wire brushing and

washing with a commercial solvent.
