3.Wash the filter in detergent and water (Fig. 31). Rinse the filter thoroughly and allow it to dry.

4.Apply enough clean SAE 30 motor oil to lightly coat the filter (Fig. 32).

5.Squeeze the filter to spread and remove excess oil (Fig. 33).

6.Replace the filter (Fig. 34).

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

7.Reinstall the air filter cover. Position the slots on the top of

the air filter cover onto the tabs at the top of the back plate (Fig. 30).

WARNING: To prevent extensive engine wear and damage to the unit, always maintain the proper oil level in the crankcase. Never operate the unit with a low oil level.

The importance of checking and maintaining the proper oil level in the crankcase cannot be overemphasized. Check oil before each use:

1.Stop the engine and allow oil to drain into the crankcase.

2.Place the engine on a flat, level surface with the cutting head shield hanging off a work bench or table to get a proper oil level reading (Fig. 24).

3.Keep dirt, grass clippings and other debris out of the engine. Clean the area around the dipstick before removing it.

4.Remove the oil fill plug.

5.Look into the oil fill hole, use a flashlight if needed. The oil should be just touching the inner most thread (Fig. 25).

6.If the oil level is not touching the inner most thread on the oil fill hole, add a small amount of oil to the oil fill hole and recheck (Fig. 25). Repeat this procedure until the oil level reaches the inner most thread on the oil fill hole.

NOTE: Do not overfill the unit.

NOTE: Make sure the O-ring is in place on the oil fill plug when checking and changing the oil (Fig. 26).

CHANGING THE OIL

CAUTION: Wear gloves to prevent injury when handling the unit.

For a new engine, change the oil after the first 10 hours of operation. Change the oil while the engine is still warm. The oil will flow freely and carry away more impurities.

1.

Unplug spark plug boot to prevent accidental starting.

2.

Remove the oil fill plug.

3.

Pour the oil out of the oil fill hole and into a container by

 

tipping the unit to a vertical position (Fig. 27). Allow ample

 

time for complete drainage.

4.

Wipe up any oil residue on the unit and clean up any oil that

 

may have spilled. Dispose of the oil according to Federal,

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable. An idle adjustment screw is between the air filter cover and the engine starter housing (Fig. 35).

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

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: The cutting attachment may spin during idle speed adjustments. 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.

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

NOTE: The cutting attachment should not rotate when the engine idles.

3.If the cutting attachment rotates when the engine idles, turn the idle speed screw counterclockwise 1/8 of a turn at a time (as needed), to reduce idle speed.

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:

 

State and local regulations.

5.

Refill the crankcase with 3.04 fluid ounce (90 ml) of SAE 30

 

SF, SG, SH oil.

NOTE: Use the bottle and spout saved from initial use to measure the correct amount of oil. The top of the label on the bottle measures approximately 3.04 ounces (90 ml) (Fig. 29).

Check the level, See Checking the Oil Level. If the level is low, add a small amount of oil and recheck. Do not overfill (Fig. 25).

6.Replace the oil fill plug.

7.Reconnect the spark plug boot.

AIR FILTER MAINTENANCE

WARNING: To avoid serious personal injury, always turn the unit off and allow it to cool before you clean or service it.

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.

Have the carburetor adjusted by an authorized service dealer.

ROCKER ARM CLEARANCE

WARNING: To avoid serious personal injury, always turn the unit off and allow it to cool before you clean or service it.

This requires disassembly of the engine. If you feel unsure or unqualified to perform this, take the unit to an authorized service center.

NOTE: Inspect the valve to rocker arm clearance with a feeler gauge after the first 10 hours of operation and every 25 hours of operation.

•The engine must be cold when checking or adjusting the valve clearance.

•This task should be performed inside, in a clean, dust free area.

1.Remove the six (6) screws on the back of the engine cover with a Flat-head or T-25 Torx screwdriver (Fig. 36).

2.Disconnect the spark plug wire.
