Setup

Separate instructions for installing the foam marker kit are denoted in each step of the Setup, where specific procedures are different from 1 machine to another. Please look for the heading describing instructions specific to the machine that you are working with before proceeding with each step of the Setup.

Note: This foam marker kit requires a mounting bracket specifically designed for your machine. Before installing this kit, contact an authorized Toro distributor to obtain the Foam Marker Finishing Kit for your machine.

Preparing the Machine

Caution

Chemicals are hazardous and can cause personal injury.

  • Read the directions on the chemical labels before handling the chemicals and follow all manufacturer recommendations and precautions.

  • Keep chemicals away from your skin. Should contact occur, wash the affected area thoroughly with soap and clean water.

  • Wear goggles and any other protective equipment recommended by the chemical manufacturer.

  1. Park the machine on a level surface, engage the parking brake, and shut off the sprayer pump.

  2. Lower the outer booms.

  3. Shut off the engine and remove the key.

  4. Clean the sprayer; refer to Cleaning the Sprayer in the machine Operator’s Manual.

Preparing the Tubing

Parts needed for this procedure:

Foam tubing assembly (bulk)1

  1. Measure the length of tubing from the bulk loop and cut it according to the tables that follow.

    Note: Set aside the remaining tubing.

  2. At each end of the cut tubing lengths, remove 7 to 10 cm (3 to 4 inches) of the black sheath to expose the blue and clear tubing.

    Note: For Multi Pro 5000 Series machines, use only a section of clear tube for the compressor to tank loop.

Operation

Using the Controls

Right boom switch—This switch activates the compressor, generating a flow of water and air to the right boom section.

Left boom switch—This switch activates the compressor, generating a flow of water and air to the left boom section.

Note: You can drop the foam simultaneously from both boom sections.

Indicator markings—These markings are located on the side of the tank; they indicate the solution level in the tank.

Foam regulator adjustment valve—This valve controls the consistency of the foam solution. Adjusting the valve, opening or closing, controls the amount of soap solution delivered to the foam nozzles. Increasing the flow results in larger, more frequent foam drops; decreasing the flow results in smaller, less frequent foam drops.

Note: Use a foam with a watery marker consistency may be helpful on windy days.

Pressure relief valve—Pull the red tab on the tank cap outward to relieve pressure in the tank.

Filling the Tank and Adjusting the Foam Density

Important: Flush the system with clean water after each use, especially after using hard water. Do not apply lubricating oils, grease, or other petroleum products to the compressor motor assembly.

  1. Ensure that the foam compressor On/Off switch is in the OFF position.

  2. Pull out on the red pressure-relief tab, and remove the black cap from the tank.

  3. Pour the proper amount of water into the tank, and then add foam concentrate through the opening in the top of the tank according to the manufacturer’s instructions.

    Important: Extreme pH levels (hardness or softness) of the water will affect the amount of foam concentrate needed.

  4. Install the cap on the tank and tighten it by hand.

  5. For the initial operation, open the foam density adjustment valve 1/8 to 1/4 turn counterclockwise ().

    g207605

    Figure 23

    1. 1/4 turn open

  6. Start operating the marking system and make a test pattern on the ground.

    Note: When you first start the marking system, allow 1 to 2 minutes for the foam to flow through the line.

  7. Adjust the foam density adjustment valve to obtain the desired consistency and spray as normal.

    Note: If you leave the foam in the line for more than 2 hours, it may become watery. Before operating after a break of 2 or more hours, run the machine for 1 to 2 minutes to remove the excess water.

    If the foam in the machine is very watery, do the following:

    1. Close the foam density adjustment valve completely.

    2. Operate for 2 minutes.

    3. Wait 1 minute and then check the consistency of the foam.

    4. Adjust the foam to achieve the desired consistency.

Maintenance

Winterizing

  1. Move the vehicle onto a level surface, engage the parking brake, stop the pump, and shut off the engine.

  2. At the tank cap, pull out on the red pressure-relief tab.

  3. Remove the tank cap from the tank.

  4. Remove the hairpin that secures the strap and tank to the compressor.

  5. Empty the tank of all soap and liquids.

  6. Assemble the tank to the compressor with the strap and hairpin.

  7. Assemble the cap onto the tank and tighten the cap.

  8. Start the foam-marker compressor and run each foam-marker nozzle for 5 minutes.

    Note: This removes the solution from the solenoids and prevents damage from freezing.

  9. Shut off the foam-marker compressor, and remove the key from the key switch.

  10. Disassemble the foam nozzles and replace the foam sponges.

Storage

  1. Move the vehicle onto a level surface, set the parking brake, stop the pump, shut off the engine, and remove the key.

  2. Relieve pressure within tank by opening the tank fill cap, install the tank fill cap, and hand tighten it.

  3. Disconnect the air and liquid tubing from the tank.

    Note: Replace air and liquid tubing together with the supplied tubing coupler.

  4. Disassemble the foam nozzles and replace the foam sponges.

  5. Empty the tank of all soap and liquids to avoid damaging the tank from freezing.
