AIR FILTER MAINTENANCE

Cleaning the Air Filter

To avoid serious personal injury, always turn your trimmer off and allow it to cool before you clean or do any maintenance on it.

Clean and re-oil the air filter every 10 hours of opera- tion. It is an important item to maintain. Not maintain- ing the air filter will VOID the warranty.

1.Remove the carburetor/air filter cover by pushing on the tab on top of the cover (Fig. 6-9).

2.Remove the air filter (Fig. 6-10).

3.Wash the filter in detergent and water. Rinse the filter thoroughly and allow it to dry.

4.Apply enough clean SAE 30 motor oil to lightly coat the filter (Fig. 6-11).

5.Squeeze the filter to spread and remove excess oil (Fig. 6-11).

6.Reinstall the filter (Fig. 6-10) and air filter cover (Fig. 6-9).

NOTE: If the unit is operated without the air filter, you will VOID the warranty.

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable by the screw next to the air filter cover (Fig 6-12).

NOTE: Careless adjustments can seriously damage your unit. An authorized service dealer should make carburetor adjustments.

Check Fuel Mixture

Old and/or improperly mixed fuel is usually the reason for the unit not running properly. Drain and refill the tank with fresh, properly mixed fuel prior to making any adjustments. See Section 5, Oil and Fuel.

Clean Air Filter

The condition of the air filter is important to the opera- tion of the unit. A dirty air filter will restrict air flow and change the air/fuel mixture. This is often mistaken for an out of adjustment carburetor. Check the condition of the air filter before adjusting the idle speed screw. See Section 6, Maintenance.

Adjust Idle Speed Screw

The cutting attachment may be spinning during idle speed adjustment. Wear protective clothing and observe all safety instructions to prevent serious personal injury.
