AIR FILTER MAINTENANCE

WARNING:

To avoid serious personal injury, always turn your trimmer off and allow it to

cool before you clean or service it.

WARNING:

Wear gloves to prevent injury when handling unit.

Cleaning the Air Filter

Failure to maintain your air filter properly can result in poor performance or

can cause permanent damage to your engine.

1. To open the air filter cover, push the locking tab on the right side of the

cover inward and pull the air filter cover slightly out and to the left (Fig.

17).

2. Remove the air filter (Fig. 18).

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.

5. Squeeze the filter to spread and remove excess oil.

6. Replace the filter (Fig. 18).

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

warranty.

7. To reinstall the air filter cover, position the hooks on the left side of the

air filter cover into the slots at the left side of the back plate (Fig. 18).

8. Swing the cover to the right and press closed so the air filter cover tab

snaps into the slot on the back plate (Fig. 19).

IDLE SPEED ADJUSTMENT

WARNING:

This unit will need to be running during idle speed adjustment. Wear

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

Also, DO NOT set unit on any surface except a clean, hard area while starting or performing

any adjustments. Debris, such as gravel, sand, dust, grass, etc., could be thrown by the

blower tube and damage property or cause serious injury to bystanders or operator.

The idle speed of the engine is adjustable. An idle adjustment screw is

between the air filter cover and the engine starter housing (Fig. 20).

NOTE: Careless adjustments can seriously damage your unit. An

authorized service dealer should make carburetor adjustments.

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.

2. Release the throttle trigger and let the engine idle. If the engine stops,

insert a small Phillips in between the air filter cover and the engine cover (Fig. 20). Turn the idle speed

screw in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly.

Checking the fuel, cleaning the air filter, and adjusting the idle speed should solve most engine

problems. If not and all of the following are true:

• the engine will not idle

• the engine hesitates or stalls on acceleration

• there is a loss of engine power

Have the carburetor adjusted by an authorized service dealer.

REPLACING THE SPARK PLUG

Use a replacement part number 753-06193. The correct spark gap is 0.025 in. (0.635 mm).

1. Stop the engine and allow it to cool.

2. Grasp the plug boot firmly and pull the cap from the spark plug.

3. Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a

5/8 in. socket counterclockwise.

CAUTION:

Do not sand blast, scrape, or clean electrodes. Grit in the engine could

damage the cylinder.

4. Replace cracked, fouled or dirty spark plug. Set the spark gap at 0.025

in. (0.635 mm) using a feeler gauge (Fig. 21).

5. Install a correctly-gapped spark plug in the cylinder head. Turn the 5/8

in. socket clockwise until snug.

If using a torque wrench, torque to:

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

6. Reinstall the spark plug boot.

Long Term Storage

1. Remove the fuel cap, tip the unit and drain the fuel into an approved container.

NOTE: Do not use fuel that has been stored for more than 30 days. Dispose of the old fuel/oil mix in

accordance with federal, state and local regulations.

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 or

2-cycle oil into the cylinder. Pull the starter rope slowly to distribute the oil. Reinstall the spark plug.

NOTE: Remove the spark plug and drain all of the oil from the cylinder before attempting to start the

unit after storage.

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. The unit is ready for storage.
