Single Stage
If you have a four stroke engine, the air filter needs to be clean and in good condition in order to stop dirt, dust, and debris from getting into the engine. It is recommended that you clean or change the air filter every 25 hours or once a season, whichever comes first. Pleated-paper air filters have to be replaced, they should not be cleaned and reused. Foam air filters can be cleaned with hot water and dish detergent then wrung dry and saturated with engine oil before reinstalling into the mower. If you have a two-stroke engine, you will not have an air filter on a snowblower.

If you have a four stroke engine, the oil level in snowblowers should be checked after 8 hours of use and changed every 50 hours of use or once every season. Fresh oil is a golden or amber color and as it gets old and used it will turn darker. Check your owner’s manual for proper viscosity oil to use during colder climate weather. If you have a two-stroke engine, you will not have engine oil.

Fuel filters can be removed and cleaned of residue, however if there is debris clogging the mesh screen inside the filter it should be replaced. Some fuel filters are located in the fuel line and some are located inside the fuel tank.

Before storing the snowblower, spray a degreaser on greasy and dirty areas, let the degreaser sit for 10-15 minutes then wipe the sprayed area with a clean cloth.

Snowblowers require clean, fresh fuel for best performance from the engine. During the off season when your snowblower is being stored the fuel should either be drained from the snowblower or a fuel stabilizer should be added to prevent clogs in the carburetor.

If the fuel cap air vent holes are blocked replace the fuel cap. During the off season cover or close the fuel cap vent.
