Know Your Unit: Components and Applications

Applications

As a trimmer, this unit is used for:

Other optional accessories may be used with the TB75SS. See list of add-ons on page 11.

Unit Components

The TB75SS trimmer includes the following key components:

Assembly Instructions

On some units, the D-handle may be preinstalled and only require loosening the screws and adjusting the D-handle to the operator. Go to step 4 for adjusting the D-handle if preinstalled.

Installing and Adjusting the D-Handle

  1. Remove the screws and bottom clamp piece that were installed on the D-handle for shipping.
  2. Place D-handle over the shaft housing and onto the bottom clamp. Place it a minimum of 6 inches (15.24 cm) from the end of the shaft grip.
  3. Start screws with a large Flat-head or T-20 Torx screwdriver. Do not tighten until you make the handle adjustment.
  4. If it was preinstalled, loosen the screws on the D-handle just enough to move the D-handle.
  5. While holding the unit in the operating position, position the D-handle to the location that provides you the best grip.
  6. Tighten the clamp screws evenly, until the D-handle is secure.

Oil and Fuel Information

Oil and Fuel 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.

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 only Troy-Bilt 2-Cycle Oil be used 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 the table below for specific gas and oil mixing ratios.

NOTE: One gallon (3.8 liters) of unleaded gasoline mixed with one 4 oz. (120 ml.) bottle of Troy-Bilt 2-Cycle Oil makes a 32:1 fuel/oil ratio.

Unleaded GasTroy-Bilt 2 Cycle OilMixing Ratio
1 US. Gallon (3.8 Liters)+ 4.0 Fl. Oz. (120 ml)32:1
1 Liter+ 30 ml32:1

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 spilled 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.

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. Check for the following:

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 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:

Tips for Best Trimming Results

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.

Maintenance and Repair Instructions

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.

WARNING: To prevent serious injury, never do maintenance or repairs with unit running. Always do maintenance and repairs on a cool unit. Disconnect spark plug wire to ensure the unit will not start.

  5. Place muffler with exhaust gasket in place and bolts inserted, against the engine, aligning the bolt holes. Tighten bolts to secure muffler to the engine. If using a torque wrench torque to: 80-90 in. lb. (9-10.2 N-m).

WARNING: If muffler is not tightened securely, it could fall off causing damage to the unit and possible serious personal injury.

  1. Reinstall air filter/muffler cover.

NOTE: Maintenance, Replacement, or Repair of the emission control devices and systems may be performed by any non-road engine repair establishment, individual or authorized service dealer.

In order to assure peak performance of your engine, inspection of the engine exhaust port may be necessary after 50 hours of operation. If you notice lost RPM, poor performance or general lack of acceleration, this service may be required. If you feel your engine is in need of this inspection, refer service to an authorized servicing dealer, or establishment for repair. DO NOT attempt to perform this process yourself as engine damage may result from contaminant's involved in the cleaning process for the port.

Carburetor Adjustment

The idle speed of the engine is adjustable through the Air filter/Muffler cover.

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. Refer to Oil and Fuel Information on page 9.

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. Refer to Air Filter Maintenance on page 16.

Adjust Idle Speed Screw

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. See Starting/Stopping Instructions, page 10.

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

  1. Release the throttle trigger and let the engine idle. If the engine stops, insert a small phillips or flat blade screwdriver into the hole in the air filter/muffler cover. 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 should solve most engine problems.

If not and:

have the carburetor adjusted by an authorized service dealer.

WARNING: When the unit is turned off make sure the cutting attachment has stopped before the unit is set down to prevent serious personal injury.

Replacing the Spark Plug

Use a Champion RDJ7Y spark plug (or equivalent). The correct air gap is 0.020 inch (0.5 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 it from the spark plug.
  2. Clean around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8 in. socket counterclockwise.
  3. Replace cracked, fouled or dirty spark plug. Set the air gap at 0.020 in. (0.5 mm) using a feeler gauge.

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

  1. Install a correctly gapped 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.

Long Term Storage

If the unit will be stored for an extended time, use the following storage procedure.

  1. Drain all fuel from the fuel tank into a container with the same 2-cycle fuel mixture. Do not use fuel that has been stored for more than 60 days. Dispose of the old fuel/oil mix in accordance to Federal, State, and Local regulations.
  2. Start the engine and allow it to run until it stalls. This ensures that all fuel has been drained from the carburetor.
  3. Allow the engine to cool. Remove the spark plug and put 1 oz. (30 ml) of any high quality motor oil or 2-cycle 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.
