PRIMARY MAINTENANCE an illustration of how dirt can ge your engine & how reasonable maintenance can protect it! Snapper uses the best available engines and components in their products in order to provide long, satisfactory service. However, proper care is essential In prolonging engine life.
PRIMARY MAINTENANCE g that dirt will quickly ruin an engine, manufacturers equip their engines with extremely efficient air cleaners to out the harmful dirt. The engine must gulp about 12,000 gallons of air for every gallon of used. Because of Its working environment, the air available to your Snapper engine Is " heavily saturated with airborne dirt particles. As the dirt particles are stopped, they build up and begin to clog the outside of the filter.
PRIMARY MAINTENANCE Air is also needed to keep your engine cool. Dirt, dust & debris build up to restrict and clog cooling air Intake screens and fins. Clean screens and fins at frequent Intervals. The engine blower housing and shrouds should be removed at least once each season or more often under dry, dusty conditions for a thorough cleaning of fins. Generally, wash foam-type filters In a dishwashlng detergent and water solution. Rinse and wring dry, then saturate with oil and squeeze out excess.
PRIMARY MAINTENANCE On 2-cycle engines, lubricaUon must be provided by an exact mixture of gasoline and 2-cycle air-cooled engine oil. A 2-cycle engine that Is mistakenly run on straight gasoline will be ruined in less than 5 mlnutesl If you keep straight gasoline In addition to pre-mixed 2-cycle engine fuel, be sure the containers are clearly marked to avoid mix-up. Snapper 2-cycle engines require a 32 to 1 mixture of gasoline and BIA certified TC-W oil such as Snapper's 2-cycle engine o11.

PRIMARY MAINTENANCE an illustration of how dirt can ge your engine & how reasonable maintenance can protect it! Snapper uses the best available engines and components in their products in order to provide long, satisfactory service. However, proper care is essential In prolonging engine life.
PRIMARY MAINTENANCE g that dirt will quickly ruin an engine, manufacturers equip their engines with extremely efficient air cleaners to out the harmful dirt. The engine must gulp about 12,000 gallons of air for every gallon of used. Because of Its working environment, the air available to your Snapper engine Is " heavily saturated with airborne dirt particles. As the dirt particles are stopped, they build up and begin to clog the outside of the filter.
PRIMARY MAINTENANCE Air is also needed to keep your engine cool. Dirt, dust & debris build up to restrict and clog cooling air Intake screens and fins. Clean screens and fins at frequent Intervals. The engine blower housing and shrouds should be removed at least once each season or more often under dry, dusty conditions for a thorough cleaning of fins. Generally, wash foam-type filters In a dishwashlng detergent and water solution. Rinse and wring dry, then saturate with oil and squeeze out excess.
PRIMARY MAINTENANCE On 2-cycle engines, lubricaUon must be provided by an exact mixture of gasoline and 2-cycle air-cooled engine oil. A 2-cycle engine that Is mistakenly run on straight gasoline will be ruined in less than 5 mlnutesl If you keep straight gasoline In addition to pre-mixed 2-cycle engine fuel, be sure the containers are clearly marked to avoid mix-up. Snapper 2-cycle engines require a 32 to 1 mixture of gasoline and BIA certified TC-W oil such as Snapper's 2-cycle engine o11.
