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
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
NOTE: Do not sandblast spark plug. Spark plug should be cleaned by scraping or wire brushing and washing with a commercial solvent.
