AIR FILTER MAINTENANCE

Cleaning the Air Filter

Clean and re-oil the air filter every 10 hours of operation. It is an important item to maintain. Failure to maintain your air filter properly can result in poor performance or can cause permanent damage to your engine.

WARNING: To avoid serious personal injury,

always turn the unit off and allow it to cool before you clean or service it.

1.Open the air filter cover. Push the tab on the left side of the cover in, swing the air filter cover out and off the air filter housing (Fig. 19).

2.Remove the air filter and the screen that sits behind it (Fig. 19).

5.Squeeze the filter to spread and remove excess oil (Fig. 21).

6.Replace the filter (Fig. 19).

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

7.Reinstall the air filter cover. Position the hooks on the right side of the air filter cover into the slots at the right side of the air filter housing.

8.Swing the cover to the left until the tab on the air filter cover snaps into place in the slot on the left side of the air filter housing (Fig. 19).

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable. An idle adjustment screw is reached though a hole in the top of the engine cover (Fig. 22).

Check Fuel

Old fuel is usually the reason for improper unit performance. Drain and refill the tank with fresh fuel prior to making any adjustments. Refer to Oil and Fuel Information.

Clean Air Filter

The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict air flow. This is often mistaken for an out of adjustment carburetor. Check the condition of the air filter before adjusting the idle speed screw. Refer to Air Filter Maintenance.

Adjust Idle Speed Screw

WARNING: This unit needs to run during idle

speed adjustment. Wear protective clothing and observe all safety instructions to prevent serious personal injury.

If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed screw as follows:

1.Start the engine and let it run at a high idle for a minute to warm up. Refer to Starting/Stopping Instructions.

NOTE: Ensure the tines are not in contact with the ground when adjusting the idle.
