Product Overview

g023144

Become familiar with all the controls before you start the engine and operate the machine.

Engine On/Off Switch

The engine on/off switch allows the engine to run when it is in the RUN position. In the STOP position, it stops the fuel from flowing to the engine and prevents the engine from running (Figure 4 or Figure 5).

g023108
g023113

Choke Lever

Use the choke lever (Figure 6 or Figure 7) to start a cold engine. Before pulling the recoil-starter handle, move the choke lever to the closed position. Once the engine is running, move the choke lever to the open position. Do not use the choke if the engine is already warmed up or if the air temperature is high.

g023107
g023112

Throttle Lever

The throttle lever controls the engine speed. When the lever is in the SLOW position, the engine runs at idle speed. This is also the starting position. When you move the lever to the FAST position, the centrifugal clutch engages, and the shoe of the machine vibrates and compacts.

Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Important: Before operating, check the fuel and oil levels and remove debris from the machine. Also, ensure that the area is clear of people and debris. You should also know and have marked the locations of all utility lines.

Preparing to Use the Machine

  • Check that the ground is free of foreign objects, such as electrical cables, barbed wire, etc.

  • Review all the safety decals on the machine.

  • Use steel-toe shoes, a hard-hat, hearing protection, and eye protection. A mesh visor alone does not provide sufficient eye protection; supplement with protective glasses.

  • Ensure that you are familiar with safety regulations and shutdown procedures described in the Operator’s Manual.

  • Ensure that all guards are in place and in good condition.

  • Ensure that the compactor shoe is in place and in good condition.

  • Ensure that everyone, including children and animals, maintain a distance of at least 15 m (50 ft) from the machine.

Adding Fuel

  • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

  • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.

  • Do not use gasoline containing methanol.

  • Do not store fuel either in the fuel tank or fuel containers over the winter unless a fuel stabilizer is used.

  • Do not add oil to gasoline.

Danger

In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.

  • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.

  • Never fill the fuel tank inside an enclosed trailer.

  • Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows fuel to expand.

  • Never smoke when handling fuel, and stay away from an open flame or where fuel fumes may be ignited by a spark.

  • Store fuel in an approved container and keep it out of the reach of children. Do not use fuel that has been stored for more than 30 days.

  • Do not operate without entire exhaust system in place and in proper working condition.

Danger

In certain conditions during fueling, static electricity can be released causing a spark which can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property.

  • Always place fuel containers on the ground away from your vehicle before filling.

  • Do not fill fuel containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

  • When practical, remove fuel-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

  • If this is not possible, then refuel such equipment on a truck or trailer from a portable container rather than from a fuel dispenser nozzle.

  • If a fuel dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Warning

Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

  • Avoid prolonged breathing of vapors.

  • Keep your face away from nozzle and fuel tank or conditioner bottle opening.

  • Avoid contact with skin; wash off spills with soap and water.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

  • Keeps fuel fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.

  • Cleans the engine while it runs

  • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting

    Important: Do not use fuel additives containing methanol or ethanol.

    Add the correct amount of fuel stabilizer/conditioner to the fuel.

    Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Filling the Fuel Tank

  1. Park the machine on a level surface and stop the engine.

  2. Allow the engine to cool.

  3. Clean around the fuel tank cap and remove it (Figure 9).

    g020337
  4. Add fuel to the fuel tank, until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck.

    Important: This space in the tank allows fuel to expand. Do not fill the fuel tank completely full.

  5. Install the fuel tank cap securely.

  6. Wipe up any spilled fuel.

Checking the Machine-Fluid Levels

Starting the Engine

  1. Move the engine on/off switch to the RUN position (counterclockwise); refer to Engine On/Off Switch.

  2. Move the choke lever to the CLOSED position if you are starting a cold engine; refer to Choke Lever.

    Note: A warm or hot engine may not require choking.

  3. Move the throttle lever to the SLOW position; refer to Throttle Lever.

  4. Pull the recoil-starter handle lightly until you feel resistance, then pull the handle briskly. Gently return the handle to the original position.

  5. After the engine starts, gradually move the choke lever back to the OPEN position. If the engine stalls or hesitates, move the choke lever back to the CLOSED position again until the engine warms up. Then move it to the OPEN position.

Shutting Off the Engine

  1. Move the throttle lever to the SLOW position. If the engine has been working hard or is hot, let it run for a minute. This helps to cool the engine before stopping.

    Important: To shut off the engine immediately, you can move the engine on/off switch to the STOP position before moving the throttle lever to the SLOW position.

  2. Move the engine on/off switch to the STOP position (clockwise).

Transporting the Machine

Caution

If you tip the machine when the engine on/off switch is in the RUN position, fuel can leak out of the fuel tank. A fuel leak could lead to a fire and cause serious personal injury.

Drain the fuel tank or ensure that the engine on/off switch is in the STOP position before tipping the machine.

Important: Before transporting the machine, secure it with straps or chains to prevent it from falling or tipping over. Ensure that the lifting device and straps or chains are properly rated; refer to Specifications.

If possible, keep the machine standing upright when transporting it. Secure it with straps or chains; do not let it fall over.

If you must transport the machine horizontally, do so as follows:

  1. Shut off the engine and allow it to cool for 15 minutes. Ensure that the engine on/off switch is in the STOP position.

    The engine on/off switch is also a fuel valve. Ensuring that it is in the STOP position prevents fuel from leaking out of the fuel tank.

  2. Use a lifting device with adequate lifting capacity (at least 75 kg, or 165.3 lb) to lift the machine into the transport vehicle.

    Important: Attach chains or other lifting-device components to only the lift eye of the machine; refer to Figure 3.

  3. Carefully position the machine as shown in Figure 10, and secure it with straps or chains to prevent it from moving or tipping.

    Important: Do not lay the machine onto the right or left side; the engine oil can leak into the air intake or the exhaust system. Lay the machine tipped forward only, so that it rests on the front bar.

    g023106
  4. After transporting the machine, stand the machine in an upright position to allow the oil to drain through the engine and settle back into the crankcase.

    Important: Allow the oil to settle for at least 2 minutes after standing the machine upright before you start the engine.

Operating Tips

  • Keep the machine upright so that it contacts the ground with the entire shoe, rather than with just the front or back edge of the shoe.

  • Allow the machine to do the work; pushing downward on the handle limits the effectiveness of the machine.

  • On level surfaces, the machine moves forward in rapid jumps. On uneven surfaces, tilt the machine as necessary to assist the forward movement.

  • The jump height of the machine increases as the ground becomes more compacted.

Maintenance

Note: Determine the left and right sides of the machine from the normal operating position.

Important: You may tip the machine forward, if you drain the fuel tank or move the engine on/off switch to the STOP position, to make cleaning or servicing the machine easier. If you lay the machine onto the side, oil can drain out of the crankcase into the air cleaner or the muffler.Allow the oil to settle for at least 2 minutes after standing the machine upright before you start the engine.

    2. Check the gap between the center and side electrodes (Figure 24).

    3. If the gap is not within the specified range, do the following:

      1. If the gap is too small, carefully bend the side electrode away from the center electrode until the gap between the electrodes is correct.

      2. If the gap is too large, carefully bend the side electrode toward the center electrode until the gap between the electrodes is correct.

    Installing the Spark Plug

    1. Thread the spark plug into the spark-plug hole.

    2. Tighten the spark plug to 27 N∙m (20 ft-lb).

      Important: Ensure that the spark plug is tightened to the specified torque value. A loose spark plug may cause damage to the cylinder, while an overtightened spark plug may cause damage to the cylinder-head threads.

    3. Connect the wire to the spark plug.

    Compactor Shoe Maintenance

    Checking the Compactor Shoe

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the compactor shoe.
  • Among the most critical elements of the machine is the compactor shoe. It is also the most subject to damage and wear. In the course of compacting a wide array of granular objects, the machine encounters numerous abrasives and objects, such as dirt, stones, and occasionally a large rock or buried scrap.

    The wear of the compactor shoe can significantly impair the efficiency and performance of the machine. Therefore, it is important to make frequent checks of the condition of the compactor shoe for leaks and cracks. (Figure 25).

    Cleaning

    Removing Debris from the Machine

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Remove debris from the machine.
  • Regular cleaning and washing will increase the life span of the machine. Clean the machine immediately after use, before the dirt hardens.

    Check before cleaning that the fuel tank cap is properly in place to avoid getting water in the tank.

    Use care when using a high-pressure sprayer because it can damage warning decals, instruction signs, and the engine.

    Storage

    For storage over 30 days, prepare the machine as follows:

    1. Remove dirt and grime from the external parts of the entire machine, especially the engine. Clean all granular objects from the outside of the engine cylinder-head fins and the blower housing.

      Important: You can wash the machine with mild detergent and water.

    2. Add a petroleum-based stabilizer/conditioner to the fuel in the tank. Follow the mixing instructions from the stabilizer manufacturer. Do not use an alcohol-based stabilizer (ethanol or methanol).

      Note: Fuel stabilizer/conditioner is most effective when mixed with fresh fuel and used at all times.

      Important: Do not store stabilizer/conditioned fuel over 90 days.

    3. Run the engine to distribute conditioned fuel through the fuel system (5 minutes).

    4. Shut off the engine, allow it to cool, and drain the fuel tank using a pump-type siphon. Dispose of fuel properly; recycle it according to local codes.

    5. Start the engine and run it until it stops.

    6. Choke the engine.

    7. Start and run the engine until it will not start again.

    8. Service the air cleaner; refer to Figure 13.

    9. Change the engine crankcase oil; refer to Figure 19.

    10. Remove the spark plug and check the condition; refer to Figure 23 and Figure 24.

    11. With the spark plug removed from the engine, pour 30 ml (2 tablespoons) of engine oil into the spark-plug hole.

    12. Pull the recoil-starter handle slowly to crank the engine and distribute the oil inside the cylinder.

    13. Install the spark plug, but do not install the wire on the spark plug.

    14. Check and tighten all bolts, nuts, and screws. Repair or replace any part that is damaged.

    15. Paint all scratched or bare metal surfaces. Paint is available from your Authorized Service Dealer.

    16. Store the machine in a clean, dry garage or storage area.

      Important: Store the machine in the upright position. Do not tip the machine on its side, or leave the machine tipped forward with the front bar down for a long period of time.

    17. Cover the machine to protect it and keep it clean.

    Removing the Machine from Storage

    1. Check and tighten all fasteners.

    2. Inspect the spark plug and replace it if it is dirty, worn, or cracked; refer to the engine Operator’s Manual.

    3. Install the spark plug until it is hand-tight, then an additional 1/2 turn if it is new, otherwise, tighten it an additional 1/8 to 1/4 turn.

    4. Perform any needed maintenance procedures.

    5. Check the engine-oil level; refer to Checking the Engine-Oil Level.

      Important: Store the machine in the upright position. Do not tip the machine on its side, or leave the machine tipped forward with the front bar down for a long period of time.

    6. Check the spring-housing oil level; refer to Checking the Spring-Housing Oil.

    7. Fill the fuel tank with fresh fuel; refer to Filling the Fuel Tank.

    8. Connect the wire to the spark plug.
