WARNING: OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS PERSONAL

INJURY. Check the oil level before each use. The importance of maintaining the proper oil level cannot be overemphasized. Change the oil according to the Maintenance Schedule.

USING THE RIGHT FUEL

The use of old fuel is the most common cause of performance problems. Use only fresh, clean unleaded gasoline.

Definition of Blended Fuels

Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs water. As little as 1% water in the fuel can make fuel and oil separate, forming acids when stored. ALWAYS use fresh fuel (less than 30 days old).

NOTE: Dispose of old fuel according to federal, state and local regulations. Using Blended Fuels

If using a blended fuel:

• Always use fresh unleaded gasoline

• Use the fuel additive STA-BIL® or an equivalent

• Drain the tank and run the engine dry before storing the unit

Using Fuel Additives

Use a fuel additive, such as STA-BIL Fuel Stabilizer or an equivalent, to inhibit corrosion and minimize gum deposits. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel, according to the instructions on the container. NEVER add fuel additives directly to the unit's fuel tank.

FUELING THE UNIT

1. Position the unit with the fuel cap facing up.

2. Remove the fuel cap.

3. Place the fuel container spout into the fill hole on the fuel tank and fill the tank.

NOTE: Do not overfill the tank.

4. Wipe up any fuel that may have spilled.

5. Reinstall the fuel cap.

6. Move the unit at least 30 ft. (9.1 m) from the fuel container and the fueling site before starting the engine.

WARNING: DO NOT USE E85 FUEL IN THIS UNIT. It has been proven that fuel

containing greater than 10% ethanol will likely damage this engine and void the warranty.

WARNING: Gasoline is extremely flammable. Ignited vapors may explode. Always stop

the engine and allow it to cool before filling the fuel tank. Do not smoke while filling the tank. Keep sparks and open flames at a distance from the area.

WARNING: Remove the fuel cap slowly to avoid injury from fuel spray. Never operate the

unit without the fuel cap securely in place.

WARNING: Add fuel in a clean, well ventilated outdoor area. Wipe up any spilled fuel

immediately. Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate.

6. Remove the screw from the rocker arm cover with a flat-head screwdriver or T-25 Torx screwdriver (Fig. 20). Remove the rocker arm cover and gasket (Fig. 21).

7. Look into the spark plug hole (Fig. 20) and pull the starter rope slowly to move the piston. Make sure:

• The piston is at the top of its travel (top dead center)

• Both rocker arms move freely and both valves are closed If these statements are not true, repeat this step.

8. Use a feeler gauge to measure the clearance between one of the valve stems and its corresponding rocker arm (Fig. 22). Repeat this process for the other valve stem and rocker arm. The recommended clearance is 0.003 – 0.006 in. (0.076 – 0.152 mm). Use a standard automotive 0.005 in. (0.127 mm) feeler gauge. The feeler gauge should slide between the rocker arm and valve stem with a slight amount of resistance, without binding (Fig. 22).

9. If the clearance is not within specification: a. Turn the adjusting nut with a 5/16 inch (8 mm) wrench or

nut driver (Fig. 22).

• To increase clearance, turn the adjusting nut

counterclockwise.

• To decrease clearance, turn the adjusting nut clockwise. b. Recheck both clearances and adjust as necessary.

10. Install a new gasket and reinstall the rocker arm cover. Torque the screw to: 20–30 in•lb (2.2–3.4 N•m).

11. Inspect and reinstall the spark plug. Refer to Maintaining the Spark Plug.

12. Reconnect the spark plug wire.

13. Reinstall the engine cover. Check the alignment of the engine cover before tightening the screws. Tighten the screws.

TINE REMOVAL AND REPLACEMENT

All tines should be replaced at the same time as they will wear evenly through normal use. Work on one side at a time.

1. Make sure the unit is off. NOTE: It may be necessary to lay the cultivator back in a horizontal

position on a flat level surface with the upper handle touching the ground. It may also be necessary to wash any dirt off the tines and shaft for ease of removal.

2. Remove the retainer from the clevis pin that is between the 2 outer tines (Fig. 11).

3. Remove the clevis pin and slide the tines off of the shaft (Fig. 11).

4. Clean and oil the shaft.

5. Slide on the new tines with the hubs facing each other (Fig. 10).

NOTE: Make sure the single tine goes on the tine shaft first with

the double tines on the outside and holes on the outer tines are aligned with the outer hole on the shaft (Fig. 10).

6. Secure the new tines to the shaft by sliding the clevis pin into the holes between the 2 outer tines (Fig. 11).

7. Insert the retainer into the clevis pin to secure the tines.

8. Repeat step 2 through 7 for the opposite side.

WARNING: To prevent serious personal injury, always wear heavy gloves when handling

the tines.

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 by unscrewing the cover screw (Fig. 16).

2. Remove the air filter from inside the air filter housing (Fig. 17).

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 inside the air filter housing (Fig. 17).

NOTE: Operating the unit without the air filter and air filter cover

will VOID the warranty.

7. Insert the hooks on the air filter housing into the slots on the air filter cover (Fig. 17).

8. Swing the air filter cover to the left and align the cover screw with the cover screw hole (Fig. 17). Tighten the cover screw to secure the air filter cover.

CHANGING THE OIL

Change the oil while the engine is still warm. The oil will flow freely and carry away more impurities.

1. Clean the area around the oil fill plug (Fig. 5) to prevent debris from entering the oil fill hole.

2. Unscrew the oil fill plug.

3. Tip the unit vertically to pour the oil out of the oil fill hole and into a container (Fig. 14). Allow ample time for complete drainage.

NOTE: Dispose of the old oil according to federal, state and local

regulations.

4. Wipe up any oil that may have spilled.

5. Pour 3.04 fl.oz. (90 ml) of SAE 30 SJ oil into the oil fill hole.

NOTE: DO NOT overfill. Refer to Checking the Oil Level. NOTE: Use the empty oil bottle saved from the initial use to

measure the correct amount of oil. Fill the bottle to the top of the label to approximate 3.04 fl.oz. (90 ml) of oil (Fig. 15).

6. Wipe up any oil that may have spilled.

7. Reinstall the oil fill plug.

NOTE: Make sure the O-ring is in place on the oil fill plug (Fig. 5).

CHECKING THE OIL LEVEL

1. Stop the engine and allow it to cool.

2. Set the unit on a flat, level surface. Position the unit so that the engine is horizontal (Fig. 12).

NOTE: Failure to keep the engine level may cause the oil to overfill.

3. Clean the area around the oil fill plug (Fig. 5) to prevent debris from entering the oil fill hole.

4. Unscrew the oil fill plug.

5. Look into the oil fill hole; use a flashlight if necessary. The oil

level should just touch the bottom thread of the oil fill hole

(Fig. 13). If the oil level is too low, add oil to the oil fill hole until the oil level touches the bottom thread of the oil fill hole.

NOTE: DO NOT overfill the crankcase.

6. Wipe up any oil that may have spilled.

7. Reinstall the oil fill plug.

NOTE: Make sure the O-ring is in place on the oil fill plug (Fig. 5).

WARNING: OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS PERSONAL

INJURY. Check the oil level before each use. The importance of maintaining the proper oil level cannot be overemphasized.
