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.

_i_ 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.
