OIL AND FUEL INFORMATION

RECOMMENDED OIL TYPE

Using the proper type and weight of oil in the crankcase is extremely important.

Check the oil before each use and change the oil regularly. Using incorrect or dirty oil can cause premature engine wear and failure.

Use a high-quality SAE 30 weight oil of API (American Petroleum Institute) service class SF, SG, SH.

ADDING OIL TO CRANKCASE: INITIAL USE

NOTE: This unit is shipped without oil in the crankcase.

In order to avoid damage to the unit, put oil in the crankcase before attempting to start unit.

Your unit is supplied with one 3.4 fluid oz. (100 ml.) bottle of SAE 30 SF, SG, SH oil (Fig. 5).

NOTE: Save the bottle to measure the correct amount

for future oil changes. See Changing the Oil.

NOTE:

Your new 4-Cycle cultivator is shipped for operation in conditions above 40°F (4°C). For cold weather operation, where temperatures fall below 40°F (4°C), use a high-quality SAE 10W30 weight oil of API (American Petroleum Institute) service class SF, SG, SH.

1. Unscrew the oil bottle top and remove the paper seal

covering the opening. Replace the top and cut the tip off the funnel spout (Fig. 5).

2. Place the unit on a flat level surface with the

cultivator in a horizontal position (Fig. 6).

3. Remove the oil plug / dipstick from the crankcase

(Fig. 7).

4. Pour the entire bottle of oil into the oil fill hole

(Fig. 8).

NOTE: Never add oil to the fuel or fuel tank.

5. Wipe up any oil that may have spilled and reinstall

the oil fill plug / dipstick.

OVERFILLING OIL

CRANKCASE MAY CAUSE PRODUCT DAMAGE. Check and maintain the proper oil level in the crank case; it is important and cannot be overemphasized. Check the oil before each use and change it as needed. See Changing

the Oil.

CAUTION:

Add fuel in a clean,

well ventilated outdoor area. Wipe up any spilled fuel immediately. Avoid creating a source of ignition for spilt fuel. Do not start the engine until fuel vapors dissipate.

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 fuel cap

slowly to avoid injury from fuel spray. Never operate the unit without the fuel cap securely in place

WARNING:

RECOMMENDED FUEL TYPE

Old fuel is the primary reason for improper unit performance. Be sure to use fresh, clean, unleaded gasoline.

NOTE: This is a four cycle engine. In order to avoid

damage to the unit, do not mix oil with 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 form acids when stored. When using alcohol-blended fuel, use fresh fuel that is less than 60 days old.

Using Blended Fuels

If you choose to use a blended fuel, or if its use is unavoidable, follow recommended precautions:

• Always use fresh unleaded gasoline

• Use Craftsman Fuel Stabilizer or an equivalent

• Drain tank and run the engine dry before storing unit

Using Fuel Additives

The use of fuel additives, such as Craftsman Fuel Stabilizer or an equivalent, will inhibit corrosion and minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful deposits in the carburetor for up to six (6) months. Add 0.8 oz. (23 ml.) of fuel additive per gallon of fuel to an approved gas container according to the instructions on the container. NEVER add fuel additives directly to the unit's gas tank.

OIL AND FUEL INFORMATION

FUELING THE UNIT

NOTE: Fill or add fuel to the tank only when the

cultivator is in a horizontal position (Fig. 9).

1. Remove fuel cap. Remove the tag from the fuel tank neck.

2. Place spout of gas container into the fill hole on the fuel tank and fill tank.

NOTE: Do not overfill tank.

3. Wipe up any gasoline that may have spilled.

4. Reinstall the fuel cap.

5. Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine.

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. 18).

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).

NOTE: Careless adjustments can seriously damage your

unit. For carburetor adjustments, take your unit to a Sears or other qualified service dealer.

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.
