    PAINTING OPERATIONS

    PREPARING TO PAINT

    The Field Marker is now ready to fill with paint. Most field paints are concentrated and require thinning at a 2:1 ratio. This is just a suggested ratio. Refer to any manufacturer's recommendations. This could change depending on the quality of paint used or quality of paint lines desired. Higher quality paints may require a 4:1 ratio of water to paint. The following is an example of how to mix a 2:1 ratio paint mixture.

    1. Mix by filling the Wide Mouth Mixing Jug with concentrate to the 1-1/2 gallon mark, and filling to the 2-1/2 gallon mark with water.
    2. Close the lid tightly, shake vigorously, and pour into the poly tank.
    3. Fill the mixing jug again with only water to the 2 gallon mark and pour into the poly tank.
    4. This procedure provides 4-1/2 gallons of field paint with a 2:1 mixture.
    5. Repeat until both tanks are full.

    IMPORTANT: Additional agitation provides better dilution of the mixture. Failure to follow this procedure results in plugging of the inlet screen on the pickup tube. The thickness or viscosity of paint may affect the flow of paint and nozzle pressure.

    SPRAYING PAINT

    You can spray paint two different ways with your Rider Field Marker. Lines are painted with the Rider by means of the Spray Shoe located under the machine and detailing can be done with the Spray Wand at the rear of the machine.

    SPRAY SHOE OPERATION

    The Spray Shoe is design for painting lines while the Rider is in a forward motion. Backing up the machine while spraying is not recommended. Operate Spray Shoe as follows:

    1. Lower Spray Shoe if in the Raised/Locked position.
    2. Adjust Spray Shoe to the desired width by turning adjusting set screws (2) located on side of Spray Shoes (See Spray Head Adjustment instructions.) with an allen wrench.
    3. Loosen adjusting knobs at front of Rider to set Line Guide to a comfortable position for operator. Tighten knobs securely.
    4. Start Rider and adjust engine speed to the "FAST" position (See Starting instructions.)
    5. Turn the switch located on the control panel to the "ON" position. The pumps will turn on and recirculate paint into the tanks.
    6. Once speed of the Rider is selected (See Wheel Drive instructions) and direction is decided, the spray nozzle applicator can be turned "ON/OFF" any time using the 2-way valve located under the seat on the left side. Moving the handle to the down position will cause the paint to flow to the spray nozzle applicator. Moving the handle to the horizontal position will turn off the paint flow.
    7. Use line guide to follow premarked course to aid in painting straight lines.

    SPRAY WAND OPERATION

    The Spray Wand is designed for painting details on the athletic field. It is recommended that the Rider be in a stationary position while the Spray Wand is in use. Operate Spray Wand as follows:

    1. Uncoil Spray Wand from hanger and hook hose into "Quick-Coupler" located at center of machine below the seat.
    2. Start Rider and adjust engine speed to the "FAST" position (See Starting instructions.)
    3. Apply Parking Brake (See Stopping instructions) and dismount machine.
    4. Turn switch located on the control panel to the "ON" position. The pumps will turn on and recirculate paint into the tanks.
    5. Turn the 2-way valve handle, located under the seat on the left side, up to allow paint to flow to the Spray Wand.
    6. Depress handle on Spray Wand to begin spraying.
    7. Adjust Spray Wand nozzle to give desired cones.

    SPRAY HEAD ADJUSTMENT

    Make a sample stripe to check line width and spray pattern. Adjusting line width is accomplished by loosening the set screws, sliding the spray shoe to desired width, then tightening the set screws. The closer the shoes are set together, the lower the Spray Head should be set. Setting of the Spray Head is accomplished by loosening the setscrew in the collar of the Spray Head with the provided Allen wrench found in the Tool Kit. The spray pattern should not contact more than ONE INCH of the bottom of the spray shoe for best paint usage.

    SPRAY SHOE LIFT

    The Spray Shoe Lift Control is provided to raise the Spray Shoe during transport or spraying over uneven ground.

    1. To lift the Spray Shoe, depress the Spray Shoe Lift Pedal on the right side of the console.
    2. To lock the Spray shoe in the raised position, depress the Lift Pedal and flip open the lock.
    3. Release raised Spray Shoe (take foot off Lift Pedal), depress Lift Pedal and close the lock.

    IMPORTANT: The Spray Shoe is not designed to spray in the Locked/Raised position. Lower Spray Shoe during painting operations.

    FLOW CONTROL VALVE

    The flow control valve is located on the left side of the machine under operator's seat. The valve comes preset from the factory at the full flow position. To restrict the flow, start by loosening the small nut located underneath the brass knurled knob by turning it counter-clockwise. Turn the knurled knob in a clockwise direction until the desired flow is achieved, then tighten down the small nut to prevent the knob from turning during operation.

    IV. MAINTENANCE

    Proper maintenance of this equipment will maintain its efficient performance and prolong the life of all elements of operation.

    CLEANING

    IMPORTANT: The single most important item to emphasize in maintaining this Field Marker is the cleaning of the unit after each use.

    1. Drain unused field paint into a separate container from the poly tanks on the Rider and rinse thoroughly with water. Each tank is equipped with a drain located on the bottom of each tank.
    2. Fill the poly tanks with clean water and flush the system, including the Spray Wand, until the discharged water runs clear (See Spraying instructions.)
    3. Use the balance of the clean water with Spray Wand to rinse the frame, wheels and tires, and Spray Shoe.
    4. Remove the spray nozzles and check valve screens, rinse with water and scrub any dried paint with brush in Tool Kit. When replacing nozzles, adjust direction with wrench in Tool Kit and tighten securely.

    IMPORTANT: When cleaning with use of Spray Wand, DO NOT spray directly into battery and engine compartments. Cleaning of the Paint Spray System is the only maintenance procedure that can be done with the engine running.
