Range of Air Filter to suit Engines, Trimmers and Chainsaws
About Foam Air Filters
The “foam only” style air filter system works by trapping dirt and debris through the use of motor oil spread throughout the oil foam holding medium. A dry or non-oiled oil foam filter will trap only the largest particles. If the air filter element is foam only, it MUST be oiled and serviced regularly. Your foam filter requires replacement every 3 months or after 25 hours of use, whichever occurs first, more often under dusty conditions.
How to Change a Foam Air Filter
1. Remove air filter.
2. Carefully remove air filter assembly and discard foam.
3. Clean all metal assembly parts.
4. Saturate new foam filter with fresh engine oil.
5. Wrap foam in clean cloth and squeeze to remove excess oil.
6. Assemble foam filter so lip extends over edge of body.
7. Reinstall assembly carburetor.
About Dual Element Air Filters
Combination air filters provide the highest degree of air filtering in the industry. The foam portion is used as a pre-cleaner for the paper element. Pre-cleaning the air increases the life of the more expensive paper element. Air passes through 2 types of filtering mediums providing clean air for the engine.
A dual air filter element will help extend the life of your engine. If you have a combination air filter with pre-cleaner, replace pre-cleaner every 25 hours or every season, and replace cartridge every 100 hours. If you do not have a pre-cleaner replace cartridge every 25 hours or every season, more often under dusty conditions.
How to Change a Dual Element Air Filter
1. Remove knob(s) and cover.
2. Carefully remove foam pre-cleaner, when so equipped.
3. Reinstall cartridge, nut(s), pre-cleaner and cover. Retighten knob(s) securely.
4. Replace if very dirty, damaged, or doesn't fit properly.
If you need to replace the air filter in your small engine, you will need to locate the part number by finding your engine model number, and once you have that you can find your small engine manual.
