Engine Maintenance
Engine Oil
Only use high quality detergent oil rated with API
service classification SF, SG or SH. Select the oil's
SAE viscosity grade according to the expected
operating temperature:
Oil Type
Temperature
Recommended Oil
Straight Grade
Above 32°F
SAE 3OW
Multi Grade
0°F to 32°F
SAE 5W30 or
SAE 10W
Synthetic
Below O°F
SAE 0W30
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 oil level more frequently to avoid possible
engine damage from running low on oil.
IMPORTANT: Refer to the viscosity chart for proper
selection of engine oil. Do not use SAE 10W40 oil.
Checking
Oil Level
1.
Before operating the snow thrower, check the oil
level. With engine on level ground, the oil must be
to FULL mark on dipstick.
2.
Stop engine and wait several minutes before
checking oil level. Remove oil fill cap and dipstick.
3.
Wipe dipstick clean, insert it into oil fill hole and
tighten securely.
4.
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.
1.
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.
2.
When engine is drained of all oil, replace drain plug
securely.
3.
Remove the dipstick from the oil fill. Pour fresh oil
slowly through the plug. Replace dipstick.
4.
Check and make sure that the level of oil is up to
the FULL mark on the dipstick. The oil sump
capacity is 21 ounces or 0.62 liters.

WARNING:
Temperature of muffler and its
nearby areas may exceed 150 ° F(65°C).
Avoid these areas.
Spark Plug
Clean the spark plug and reset the gap to 0.030" at
least once a season or every 100 hours of operation.
See Figure 10. Replace if necessary.
1.
Clean area around the spark plug base.
2.
Remove and inspect the spark plug.
3.
Replace the spark plug if electrodes are pitted,
burned, or the porcelain is cracked. See Figure 10.
4.
For replacement, use Champion J-8C, Autolite 356
or equivalent spark plug.
NOTE: Do not sandblast spark plug. Spark plug should
be cleaned by scraping or wire brushing and washing
with a commercial solvent.
