Checking the Engine Oil Level

Maintenance Service IntervalMaintenance Procedure
Before each use or daily
  • Check the engine oil level.
  • The engine crankcase can hold 0.55 liters (20 ounces) of oil. Use only high-quality SAE 10W-30 weight detergent oil that has the American Petroleum Institute (API) service classification SH, SJ, Sl or higher.

    Note: When the crankcase is empty, pour about 3/4 of the crankcase capacity of oil in the crankcase, then follow the procedure in this section.

    1. Move the machine to a level surface.

    2. Clean around the dipstick (Figure 10).

      g017580
    3. Remove the dipstick by rotating the cap counterclockwise and pulling it out.

    4. Wipe the dipstick clean with a clean cloth.

    5. Insert the dipstick into the filler neck, but do not rotate the cap clockwise to secure it, then remove it.

    6. Read the oil level on the dipstick.

    7. If the oil level reading is below the lower limit mark on the dipstick, remove the dipstick and slowly pour only enough oil into the filler hole to raise the oil level to the upper limit mark on the dipstick.

      Important: Do not overfill the crankcase with oil and run the engine; engine damage will result. Drain the excess oil until the oil level reaches the upper limit mark on the dipstick.

    8. Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight.

    Filling the Fuel Tank with Gasoline

    • Fuel tank capacity: 3.76 L (0.99 US gallon)

    • Recommended 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.

    Important: Do not use fuel additives other than a fuel stabilizer/conditioner. Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.

    Danger

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

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

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

    • Never smoke when handling gasoline, and stay away from an open flame or where a spark may ignite the gasoline fumes.

    • Store gasoline in an approved fuel container and keep it out of the reach of children.

    • Never buy more than a 30-day supply of gasoline.

    Danger

    When fueling, under certain circumstances, a static charge can develop, igniting the gasoline. A fire or explosion from gasoline can burn you and others and damage property.

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

    • Do not fill gasoline 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 gasoline-powered equipment from the truck or trailer and refuel the equipment with its wheels on the round.

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

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

    1. Clean around the fuel tank cap (Figure 11).

      g023850
    2. Remove the cap from the tank.

    3. Fill the fuel tank with unleaded gasoline to within 6 to 13 mm (1/4 to 1/2 inch) from the top of the tank. Do not fill into the filler neck.

      Important: Do not fill the tank more than 6 mm (1/4 inch) from the top of the tank because the gasoline must have room to expand.

    4. Install the fuel tank cap and wipe up any spilled gasoline.

    Starting the Engine

    1. Connect the wire to the spark plug.

    2. Open the fuel valve by turn it in-line with the fuel hose ().

      g017588
    3. Move the throttle control all the way forward to the Choke position (Figure 12).

      Note: Do not use the choke when the engine is warm.

      g016910
    4. Pull the starter handle lightly until you feel resistance, then pull it sharply. Allow the rope to return to the handle slowly.

    5. When the engine starts, move the throttle control to the Fast position.

      Note: The throttle setting governs the maximum drive speed of the aerator.

    Stopping the Engine

    1. Release the traction control lever and allow it to return to neutral.

    2. Move the throttle lever all the way rearward to stop the engine.

    Driving the Machine

    • To move forward, press the control lever forward (Figure 14). The further forward you push it, the faster the machine will travel.

    • To move in reverse, pull the control lever rearward (Figure 14). The further rearward you pull it, the faster the machine will travel.

      Warning

      The aerator tines are sharp and can puncture your feet or other body parts.

      Use extreme care when moving in reverse so that you do not allow your feet to go close to the tines. Watch for and avoid obstacles you could trip over.

    • To turn the machine, move slowly and press down on the handles; turn the machine in the desired direction then resume normal operation.

    • To make zero turns, pull up on the tine ground engagement lever and raise the tines.

      Important: Do not make a zero turn when the tines are down. Turning with the tines down will result in turf tearing.

      Important: Do not drive the machine across pavement or other hard surfaces without first raising the tines. Crossing hard surfaces with the tines lowered will damage the tines.

    Adding Weight

    To ensure that the tines penetrate fully into the soil, you can add weight to the back of the machine. The machine has three weight pockets that hold the weights (Figure 16). When placing weight, ensure that you have a balanced load; if using only one weight, place it in the center pocket and if using two, place them in the side pockets.

    g017584

    Adjusting the Coring Depth

    A coring depth of 6.35 cm (2-1/2 inches) is recommended, but you can change the depth as follows:

    1. Stop engine, wait for all moving parts to stop.

    2. Disconnect the wire from the spark plug.

    3. Loosen the nuts securing the wheel stop on the right side of the machine (see Figure 17).

      g023022
    4. Lower the wheel stop to reduce the depth. Raise it to increase the coring depth and as required.

      Note: To ensure that the tines penetrate fully into the soil, weights can be added to the back of the machine. The machine has three weight pockets that hold the weights. When placing weight, ensure that the load is balanced; if using only one weight, place it in the center pocket and if using two, place them in the side pockets.

      Note: The removable weights are heavy. Use care when lifting them. Make sure that you can hold them securely before lifting them. Use caution when positioning your hands so that you do not set them down on your hands or fingers.

    5. Tighten the nuts securely to lock the wheel stop in place.

    6. Repeat steps 3 through 5 for the wheel stop on the left side of the machine. Use the visual indicator notches in the wheel stop and indicator holes in the frame to set the wheel stops to the same height on each side (see Figure 17).
