OIL AND FUEL INFORMATION

RECOMMENDED OIL TYPE

Using the proper type and weight of oil in the crankcase is extremely important. Check oil before each use while the engine is cold and change the oil every 25 hours of operation. Failure to use the correct oil, or using 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 order to avoid damage to the unit, put oil in the crankcase before you attempt to start the unit.

Your unit is supplied with one 3.04 fluid oz. (90 ml.) bottle of SAE 30 SF, SG, SH oil (Fig. 9).

NOTE: Save the bottle of oil. It can

be used to measure the correct amount during future oil changes (Fig. 9). See Changing the Oil.

1. Unscrew the top of the bottle of oil and remove the paper seal covering the opening. Replace the top. Next, cut the tip off the funnel spout (Fig. 9).

2. Remove the oil fill plug from the crankcase (Fig. 10).

3. Tilt the unit backwards 30° (Fig. 11).

4. Pour the entire bottle of oil into the oil fill hole (Fig. 11).

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.

Check oil before each use while the engine is cold and change the oil every 25 hours of operation. Refer to Checking the Oil Level.

CHECKING THE OIL LEVEL

Check the oil only when the engine is off and cool.

1. Place the unit on its stand on a level surface.

2. Remove the oil fill plug from the crankcase (Fig. 10).

3. Look into the oil fill hole (Fig. 10). If the oil level comes up to the first thread, then the oil is full (Fig. 12). If it does not, fill with oil until it does.

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 and oil separate or form acids when stored. Use fresh fuel (less than 60 days old), when using alcohol-blended fuel.

Using Blended Fuels

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

• Always use fresh unleaded gasoline

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

• Drain tank and run the engine dry before storing unit

Using Fuel Additives

The use of fuel additives, such as STA-BIL® Gas 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 according to the instructions on the container. NEVER add fuel additives directly to the unit's gas tank.

FUELING THE UNIT

1. Remove the fuel cap.

2. Place the gas container’s spout into the fill hole on the fuel tank (Fig. 13) and fill the tank.

NOTE: Do not overfill the 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.

NOTE: Dispose of the old gasoline in accordance to Federal, State

and Local regulations.

Fig. 11

WARNING:

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:

OVERFILLING OIL CRANKCASE MAY CAUSE SERIOUS PERSONAL INJURY. Check and maintain the proper oil level in the crank case; it is important and cannot be overemphasized. Check the oil before each use while the engine is cold and change it as needed. See Changing the Oil.

1. Remove the eight (8) screws on the back of the engine cover with a Flat-head or T-25 Torx screwdriver (Fig. 30).

2. Disconnect the spark plug wire.

3. Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8 in. socket counterclockwise.

4. Remove the engine cover (Fig. 30).

5. Clean dirt from around the rocker arm cover. Remove the screw holding the rocker arm cover with a large flat blade screwdriver or Torx T25 bit (Fig. 31). Remove the rocker arm cover and gasket.

6. Pull the starter rope slowly to bring the piston to the top of its travel, (known as top dead center). Check that:

• The piston is at the top of its travel while looking in the spark plug hole (Fig. 32).

• Both rocker arms move freely, and both valves are closed.

If these statements are not true, repeat this step.

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 (Figs. 24 & 28).

8. Swing the cover down until the tab on the air filter backplate snaps into place in the slot on the air filter cover (Fig. 28).

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. 29).

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

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. 29). 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.

MAINTENANCE AND REPAIR INSTRUCTIONS

7. Slide the feeler gauge between the rocker arm and the valve return spring. Measure the clearance between the valve stem and rocker arm (Fig. 32). Measure both the intake and exhaust valves.

The recommended clearance for both intake and exhaust is .003 – .006 in. (.076 – 0.152 mm). Use a standard automotive .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. See Figures 32 and 33.

8. If the clearance is not within specification:

a. Turn the adjusting nut (Fig. 33) using a 5/16 inch (8 mm) wrench

or nut driver.

• To increase clearance, turn the adjusting nut counterclockwise.

• To decrease clearance, turn the adjusting nut clockwise.

b. Recheck both clearances, and adjust as necessary.

9. Reinstall the rocker arm cover using a new gasket. Torque the screw to 20–30 in•lb (2.2–3.4 N•m).

10. Check the spark plug and reinstall. See Replacing the Spark Plug.

11. Replace the spark plug wire.

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

REPLACING THE SPARK PLUG

Use a replacement part number 753-05255 spark plug. The correct air gap is 0.025 in. (0.635 mm.). Remove the plug after every 25 hours of operation and check its condition.

1. Stop the engine and allow it to cool. Remove the eight (8) screws on the back of the engine cover with a Flat-head or T25 Torx screwdriver (Fig. 30).

2. Grasp the plug wire 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.

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

0.025 in. (0.635 mm.) using a feeler gauge (Fig. 34).

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.
