Oil and Fuel

Section 4

Oil and Gas Mixing Instructions

Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.

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. It forms acids when stored. When using alcohol-blended fuel, use fresh fuel (less than 60 days old).

Using Blended Fuels

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

• Always use fresh fuel mix per your operator's manual.

• Always agitate the fuel mix before fueling the unit.

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

Using Fuel Additives

The bottle of Cub Cadet 2-Cycle oil that came with your unit contains a fuel additive which will help inhibit corrosion and minimize the formation of gum deposits.It is recommended that you use only Cub Cadet 2-Cycle oil with this unit.

If unavailable, use a good 2-cycle oil designed for air-cooled engines along with a fuel additive, such as STA-BIL® Gas Stabilizer or an equivalent. 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.

For proper engine operation and maximum reliability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.

Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in a separate fuel can. Use a 32:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank. See Figure 4-1 for specific gas and oil mixing ratios.

NOTE: One gallon (3.8 liters) of unleaded gasoline mixed with one 4 oz. (118 ml) bottle of Cub Cadet 2-CYCLE OIL makes a 32:1 fuel/oil ratio.

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.

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

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

NOTE: Dispose of the old fuel/oil mix in accordance to

Federal, State, and Local regulations.

Operation (continued)

HOLDING THE TRIMMER

Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating this unit.

Before operating the unit, stand in the operating position (Fig. 5-4). Check for the following:

• The operator is wearing eye protection and proper clothing.

• The right arm is slightly bent, and the hand is holding the shaft grip.

• The left arm is straight, and the hand is holding the D-handle.

• The unit is at waist level.

• The cutting attachment is parallel to the ground and easily contacts the vegetation to be cut without the operator having to bend over.

ADJUSTING TRIMMING LINE LENGTH

The Bump Head cutting attachment allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting attachment on the ground (Fig. 5-5) while operating the trimmer at high speed.

NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as cutting line becomes shorter.

Each time the head is bumped, about 1 inch (25.4 mm) of trimming line is released. A blade in the cutting attachment shield will cut the line to the proper length if excess line is released.

For best results, tap the Bump Head on bare ground or hard soil. If line release is attempted in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.

NOTE: Do not rest the Bump Head on the ground while the unit is running .

Do not remove or alter the line cutting blade assembly. Excessive line length will make the clutch overheat. This may lead to serious personal injury or damage to the unit.

Some line breakage will occur from:

• Entanglement with foreign matter

• Normal line fatigue

• Attempting to cut thick, stalky weeds

• Forcing the line into objects such as walls or fence posts

TIPS FOR BEST TRIMMING RESULTS

• Keep the cutting attachment parallel to the ground.

• Do not force the cutting attachment. Allow the tip of the line to do the cutting, especially along walls. Cutting with more than the tip will reduce cutting efficiency and may overload the engine.

• Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag.

• Cut from left to right whenever possible. Cutting to the right improves the unit's cutting efficiency. Clippings are thrown away from the operator.

• Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forward-backward or side-to-side motion. Cutting shorter lengths produces the best results.

•Trim only when grass and weeds are dry.

• The life of your cutting line is dependent upon;

• Following the previous trimming techniques

• What vegetation is being cut

• Where it’s being cut

For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree.

5. Squeeze the filter to spread and remove excess oil (Fig. 6-11).

6. Reinstall the filter (Fig. 6-10) and air filter cover (Fig. 6-9).

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

SPARK ARRESTOR MAINTENANCE

To avoid serious personal injury, always turn your trimmer off and allow it to cool before you clean or do any maintenance on it.

1. Turn the powerhead so the back of the engine is facing forward. In this position, the starter rope is to the left (Fig. 6-12).

Adjust Idle Speed Screw

The cutting attachment may be spinning during idle speed adjustment. Wear protective clothing and observe all safety instructions to prevent serious personal injury.

If after checking the fuel mixture 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.

2. Release the throttle trigger and let the engine idle. If the engine stops, insert a small phillips or flat blade screwdriver into the screw next to the air filter cover (Fig. 6-14). 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 mixture, cleaning the air filter, and adjusting the idle speed screw should solve most engine problems.

If not and:

• 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.

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable by the screw next to the air filter cover (Fig 6-14).

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

Check Fuel Mixture

Old and/or improperly mixed fuel is usually the reason for the unit not running properly. Drain and refill the tank with fresh, properly mixed fuel prior to making any adjustments. See Section 5, Oil and Fuel.

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 and change the air/fuel mixture. This is often mistaken for an out of adjustment carburetor. Check the condition of the air filter before adjusting the idle speed screw. See Section 6, Maintenance.

2. Use a needlenose pliers to grasp the collar of the spark arrestor and pull it out of the muffler (Fig. 6-13).

NOTE: Use only a needlenose pliers. Other pliers or tools may damage the spark arrestor.

3. Clean the spark arrestor with a wire brush. Replace if damaged or unable to clean thoroughly.

4. Reinstall spark arrestor. Use the needlenose pliers to gently push the spark arrestor back into the muffler until it snaps into place.

CLEANING

To avoid serious personal injury, always turn your trimmer off and allow it to cool before you clean or do any maintenance on it.

Use a small brush to clean off the outside of the unit. Do not use strong detergents. Household cleaners that contain aromatic oils such as pine and lemon, and such as kerosene, can damage plastic housing or handle. Wipe off any moisture with a soft cloth.

STORAGE

• Never store the unit with gasoline in the tank where fumes may reach an open flame or spark.

• Allow the engine to cool before storing.

• Store the unit locked up to prevent unauthorized use or damage.

• Store the unit in a dry, well ventilated area.

• Store the unit out of the reach of children.

LONG TERM STORAGE

If the unit will be stored for an extended time,

1. Drain all fuel from the gas tank into a container. Do

not use fuel that has been stored for more than 60 days. Dispose of the old fuel in accordance to Federal, State, and Local regulations.

2. Start the engine and allow it to run until it stalls.

This ensures that all gasoline has been drained from the carburetor.

3. Allow the engine to cool. Remove the spark plug

and put 1 oz. (30 ml) of high quality motor 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 trimmer after storage.

4. Thoroughly clean the unit and inspect for any loose

or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. The unit is ready for storage.

TRANSPORTING

• Allow the engine to cool before transporting.

• Secure the unit while transporting.

• Drain the gas tank before transporting.

• Tighten gas cap before transporting.

REPLACING THE SPARK PLUG

Use a Champion RCJ6Y spark plug (or equivalent). The correct air gap is 0.025 inch (0.655 mm). Remove the plug after every 25 hours of operation and check its condition.

1. Stop the engine and allow it to cool. Grasp the plug wire firmly and pull the cap from the spark plug.

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

3. Replace cracked, fouled or dirty spark plug. Set the air gap at 0.025 inch (0.655 mm) using a feeler gauge (Fig. 6-15).

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

4. Install a correctly gaped spark plug in the cylinder head. Tighten by turning the 5/8 inch 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.
