MAINTAINING THE AIR FILTER

Failure to maintain the air filter can result in poor performance or can cause permanent damage to the engine. Engine failure due to improper air filter maintenance is not covered by the product warranty.

Cleaning the Air Filter

1. Open the air filter cover; unscrew the cover screw and swing the air filter cover to the right (Fig. 20).
2. Remove the air filter (Fig. 21).
3. Wash the air filter in detergent and water. Rinse the air filter thoroughly and allow it to dry.
4. Lightly coat the air filter with clean SAE 30 oil.
5. Squeeze the air filter to spread and remove excess oil.
6. Reinstall the air filter (Fig. 21).

NOTE: Make sure the metal screen is seated in the air filter housing before reinstalling the air filter (Fig. 20).

NOTE: Operating the unit without the air filter and air filter cover will Void the warranty.

1. Close the air filter cover: insert the hooks on the air filter cover into the slots on the air filter housing. Swing the air filter cover to the left and align the cover screw with the cover screw hole (Fig. 22). Tighten the cover screw to secure the air filter cover.

NOTE: Do not over tighten as this may strip the screw.

ADJUSTING THE IDLE SPEED

WARNING: The blade may spin during idle speed adjustments. Wear protective clothing and observe all safety instructions to prevent serious personal injury.

If the engine will not idle properly:

1. Start the engine. Refer to Starting and Stopping.
2. Release the throttle control and let the engine idle.

NOTE: Make sure the blade is not in contact with the ground when adjusting the idle speed.

• If the engine stops, increase the idle speed. Use a small Phillips screwdriver to turn the idle speed screw clockwise, 1/8 of a turn at a time, until the engine idles smoothly (Fig. 23).
• If the blade spins when the engine idles, reduce the idle speed. Turn the idle speed screw counterclockwise, 1/8 of a turn at a time, until the blade stops moving (Fig. 23).

MAINTAINING THE SPARK PLUG

WARNING: Do not sand blast, scrape or clean spark plug electrodes. Grit in the engine could damage the cylinder.

1. Stop the engine and allow it to cool. Grasp the spark plug boot firmly and pull it from the spark plug.
2. Clean around the spark plug. Remove the spark plug from the cylinder head with a 5/8-inch socket, turning counterclockwise.
3. Inspect the spark plug. If the spark plug is cracked, fouled or dirty, replace it with:

USA: replacement part #794-00082, a Champion RDZ4H or an equivalent spark plug.
Canada: replacement part #794-00098, a Champion QDZ4H or an equivalent spark plug.

1. Use a feeler gauge to set the air gap at 0.025 in. (0.635 mm) (Fig. 24).
2. Install the spark plug in the cylinder head. Tighten the spark plug with a 5/8-inch socket, turning it clockwise until snug.

NOTE: If using a torque wrench, torque to:

110-120 in. lb. (12.3-13.5 N·m). Do not over tighten.

1. Reattach the spark plug boot.

CLEANING AND STORAGE

CLEANING

WARNING: To avoid serious personal injury, always stop the engine and allow it to cool before cleaning or maintaining the unit.

• Use a small brush to clean the outside of the unit.
• Do not use strong detergents. Household cleaners that contain aromatic oils such as pine and lemon, and solvents such as kerosene, can damage plastic.
• Wipe off any moisture with a soft cloth.
• Clean the edger blade with water. Wipe the edger blade with a light machine oil to prevent rust.

STORAGE

WARNING: Store the unit out of the reach of children. Lock up the unit to prevent unauthorized use or damage.

WARNING: Store the unit in a dry, well-ventilated area. Never store a fueled unit where fumes may reach an open flame or spark. Allow the engine to cool before storing.

Long-term Storage

1. Remove the fuel cap, tip the unit and drain the fuel into an approved container. Reinstall the fuel cap.
2. Start the engine and allow it to run until it stalls. This ensures that all fuel has been drained from the carburetor.
3. Allow the engine to cool. Remove the spark plug and put 5 drops of any high-quality motor oil into the cylinder. Pull the starter rope slowly to distribute the oil. Reinstall the spark plug.
4. Thoroughly clean the unit and inspect it for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts.

Preparing the Unit for Use after Long-term Storage

1. Remove the spark plug. Tip the unit and drain all of the oil from the cylinder into an approved container. Reinstall the spark plug.
2. Change the oil. Refer to Changing the Oil.

NOTE: Do not use fuel that has been stored for more than 30 days. Dispose of old fuel and oil according to federal, state and local regulations.
