UNLEADED GAS
TROY-BILT 2 CYCLE OIL

1 US. GALLON

(3.8 LITERS)

Fig. 4-1

4.0 FL. OZ.

(118 ml)

MIXING RATIO - 32:1

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 TROY-BILT 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 TROY-BILT 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.

CAUTION

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 TROY-BILT 2-CYCLE OIL makes a 32:1 fuel/oil ratio.

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

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

Fig. 5-1

STARTING INSTRUCTIONS

WARNING

Operate this unit only in a well ventilated area outdoors. Carbon monoxide exhaust fumes can be lethal in a confined area.

WARNING

Avoid accidental starting. Be in the starting position whenever pulling the starting rope. To avoid serious personal injury, the operator and unit must be in a stable position while starting.

4. Place the choke lever in the START (A) position (Fig. 5-2).
5. With the unit on the ground, squeeze the throttle control and hold. Pull starter rope briskly (Fig. 5-3). Continue pulling until the engine sounds as though it wants to run (normally 2 to 5 pulls).

NOTE: Squeeze the throttle control until the engine has started and warmed up.

1. Place the choke lever in the RUN (B) position (Fig. 5-2).
2. Pull starter rope briskly 1 to 3 times to start the engine (Fig. 5-3).
3. If the engine does not start, repeat steps 4 through 7.

NOTE: If the engine floods while trying to start, place the choke lever in the RUN (B) position. Squeeze the throttle control. Pull the starter rope briskly. The engine should start within three (3) to eight (8) pulls.
9. Squeeze the throttle control to warm up engine for 5 to 10 seconds. Place the choke lever in the RUN (B) position (Fig. 5-2).

NOTE: Choking is unnecessary when starting a warm engine. Put the On/Off Stop Control in the START (I) position (Fig. 5-1), and the choke lever in the RUN (B) position (Fig. 5-2).

STOPPING INSTRUCTIONS

1. Release your hand from the throttle control (Fig. 5-3). Allow the engine to idle.
2. To stop the engine, put the On/Off Stop Control in the STOP [O] position (Fig. 5-1).

HOLDING THE TRIMMER

WARNING

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.

CAUTION

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.

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all vegetation around trees, posts, fences, etc.

Rotate the whole unit so that the cutting attachment is at a 30^ angle to the ground (Fig. 5-6).

Section 6

MAINTENANCE

NOTE: Some maintenance procedures may require special tools or skills. If you are unsure about these procedures take your unit to an authorized service dealer.

MAINTENANCE SCHEDULE

These required maintenance procedures should be performed at the frequency stated in the table. They should also be included as part of any seasonal tune-up.

LINE INSTALLATION

This section covers both Membrane line and standard single line installation.

Always use manufacturer's 0.095 inch (2.41 mm) replacement line. Line other than specified may make the engine overheat or fail.

WARNING

Never use metal-reinforced line, wire, chain, or rope, etc. These can break off and become a dangerous projectile.

There are two methods to replace the trimming line.

• Wind the inner reel with new line
  Install a prewound inner reel

Winding the Existing Inner Reel

1. Hold the outer spool with one hand and unscrew the Bump Knob clockwise (Fig. 6-1). Inspect the bolt inside the Bump Knob to make sure it moves freely. Replace the Bump Knob if damaged.
2. Remove the inner reel from the outer spool (Fig. 6-1).
3. Remove spring from the inner reel (Fig. 6-1).
4. Use a clean cloth to clean the inner reel, spring, shaft, and inner surface of the outer spool.
5. Check the indexing teeth on the inner reel and outer spool for wear (Fig. 6-2). If necessary, remove burrs or replace the reel and spool.

NOTE: Membrane line can only be used with the inner reel with the slotted holes. Single line can be used on either type of inner reel. Use figure 6-3 to identify the inner reel you have.

NOTE: Always use the correct line length when installing trimming line on the unit. The line may not release properly if the line is too long.

Single Line Installation

Go To Step 8 for Membrane Line Installation

1. Take approximately 40 feet (12.2 m) of new trimming line, loop it into two equal lengths. Insert each end of the line through one of the two holes in the inner reel (Fig. 6-4). Pull the line through the inner reel so that the loop is as small as possible.
2. Wind the lines in tight even layers, onto the reel (Fig. 6-5). Wind the line in the direction indicated on the inner reel. Place your index finger between the two lines to stop the lines from overlapping. Do not overlap the ends of the line. Proceed to step 11.

Membrane Line Installation

1. Take approximately 20 feet (6.1 m) of new trimming line. Insert one end of the line through one of the two holes in the inner reel (Fig. 6-6). Pull the line through the inner reel until only about 4 inches is left out.
2. Insert the end of the line into the open hole in the inner reel and pull the line tight to make the loop as small as possible (Fig. 6-6).
3. Before winding, split the line back about 6 inches.
4. Wind the line in tight even layers in the direction indicated on the inner reel.

NOTE: Failure to wind the line in the direction indicated will cause the cutting attachment to operate incorrectly.

1. Insert the ends of the line into the two holding slots (Fig. 6-7).
2. Insert the ends of the line through the eyelets in the outer spool and place inner reel with spring inside the outer spool (Fig. 6-8). Push the inner reel and outer spool together. While holding the inner reel and outer spool, grasp the ends and pull firmly to release the line from the holding slots in the reel.

NOTE: The spring must be assembled on the inner reel before reassembling the cutting attachment.

1. Hold the inner reel in place and install the Bump Knob by turning counterclockwise. Tighten securely.

INSTALLING A PREWOUND REEL

1. Hold the outer spool with one hand and unscrew the Bump Knob clockwise (Fig. 6-1). Inspect the bolt inside the Bump Knob to make sure it moves freely. Replace the Bump Knob if damaged.
2. Remove the old inner reel from the outer spool (Fig. 6-1).
3. Remove the spring from the old inner reel (Fig. 6-1).
4. Place the spring in the new inner reel.

NOTE: The spring must be assembled on the inner reel before reassembling the cutting attachment.

1. Insert the ends of the line through the eyelets in the outer spool (Fig. 6-8).
2. Place the new inner reel inside the outer spool. Push the inner reel and outer spool together. While holding the inner reel and outer spool, grasp the ends and pull firmly to release the line from the holding slots in the spool.
3. Hold the inner reel in place and install the Bump Knob by turning counterclockwise. Tighten securely.

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.

Adjust Idle Speed Screw

WARNING

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. 6-12). 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.

1. 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.

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 50 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. 6-13).

CAUTION

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

1. 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.

CLEANING

WARNING

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.

1. 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.
