PAPER AIR FILTERS

A paper air filter element works by causing any air that is intended to enter the combustion chamber of the engine to pass through a filtering device made with microscopic holes in it. The paper element traps the dirt particles on the outside of the element.

How to change the paper air filter:

  1. Loosen cover screw.
  2. Tilt cover down.
  3. Carefully remove and discard paper cartridge.
  4. Install new cartridge with paper pleat out.
  5. Close cover.
  6. Tighten screw securely.


FOAM AIR FILTERS

This air filter system works by trapping dirt and debris through the use of motor oil spread throughout the foam filter. A dry or non-oiled oil air filter is less efficient and will only trap the largest particles. For optimum performance the air filter MUST be oiled regularly.

How to change the foam air filter:

  1. Remove air filter screw.
  2. Carefully remove air filter assembly and discard foam.
  3. Clean all metal air filter 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 air filter body.
  7. Reinstall air filter assembly carburetor.


DUAL ELEMENT AIR FILTER

Combination 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 two types of filtering mediums providing clean air for the engine.

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.
