Preparation • Do not touch parts which may be hot from operation. Allow them to cool before attempting to maintain, adjust, or service the machine. Become familiar with the safe operation of the equipment, operator controls, and safety signs. • Never move the machine while the engine is running. • Ensure that all the guards and shields are securely in place • Use only accessories and attachments approved by the manufacturer. before operating the machine. • Wear a respirator or a dust mask.
Hauling 1 2 • Ensure that the transport vehicle has a carrying capacity to handle the weight of the machine and a full tank of fluid—in addition to any other machines or materials that the transport vehicle may need to carry. The mixing system alone requires a carrying capacity of at least 2,268 kg (5,000 lb) for a system that uses a single 1,893 L (500-gallon) tank, up to 9,072 kg (20,000 lb) for a system that uses two 3,785 L (1000-gallon) tanks.

Circulation Valve Product Overview 1 The circulation valve (Figure 10) controls the flow from the pump to the tank. 2 8 Suction Valve 3 7 The suction valve (Figure 10) controls the flow from the tank to the pump. 6 Hopper Valve The hopper valve (Figure 10) controls the flow from the hopper into the mixing system. The hopper valve is most effective when it is just slightly open, as the fluid then creates a vacuum effect and draws the bentonite and other components into the flow.

DANGER WARNING 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. Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. • Avoid prolonged breathing of vapors. • Keep your face away from the nozzle and the fuel tank or conditioner opening.

Place the machine on a flat, level surface, and stop the engine.
Stopping the Engine • To start a cold engine, move the choke lever to the Closed position—all the way to the left (Figure 19); refer to Choke Lever (page 10). WARNING • To start a warm engine, move the choke lever in In an emergency situation, stop the engine immediately. the Open position—all the way to the right. 4. Rotate the engine switch to the On position (Figure 19); refer to Electric-start Switch (page 10).
Ensure that there is enough room for additives in the mixing system. 1 4. Test the pH of the water. If it is below 8, add soda ash until the pH is 8 or higher. Note: Supplies for testing pH are available where swimming-pool supplies are sold. 5. Slightly open the valve at the bottom of the hopper. Note: The valve works more effectively when it is open only slightly; it creates a vacuum effect that allows the dry components to enter the mixer at a faster rate. 2 6.
3. Drain the tank; refer to Draining the Tank (page 16). Operating Tips 4. Drain any remaining fluid from the pump by removing the drain plug in the bottom of the pump (Figure 22). • Use the correct fluid formula for the situation and the soil conditions. • When using fluid with any polymer in it, do not over-mix the fluid, as over-mixing can lower the viscosity of it. Partially close the circulation valve, or decrease the engine speed; refer to Throttle Lever (page 10).
Maintenance Important: Before performing any maintenance procedures, first stop the engine, wait 5 minutes to allow all moving parts to come to a complete stop and cool, and disconnect the spark-plug wire. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 25 hours • Change the engine oil. Before each use or daily • Check the engine-oil level. • Inspect the air-cleaner elements. After each use • Clean the machine.
Premaintenance Procedures Lubrication Preparing the Machine for Maintenance Service Interval: Every 100 hours Lubricating the Pump Grease Type: NLGI #1 heavy-duty EP grease (Toro part 505-162) 1. Park the transport vehicle on a level surface and chock the tires, or remove the machine from the transport vehicle. Use a grease gun to pump grease into the grease fitting on the side of the pump (Figure 24). 2. Ensure that the engine and muffler are cool. 3.
Engine Maintenance 1 Servicing the Air Cleaner 2 Service Interval: Before each use or daily—Inspect the air-cleaner elements. Every 50 hours—Clean the air-cleaner elements. Clean them more frequently in dusty operating conditions. 3 Every 300 hours/Yearly (whichever comes first)—Replace the paper air-cleaner element. Replace it more frequently in dusty operating conditions. 4 Important: Do not operate the engine without the air-filter assembly; extreme engine damage will occur. 1.
Draining the Engine Oil 10. Rinse and dry the foam element thoroughly. 11. Dip the foam element in clean engine oil, then squeeze out the excess oil. WARNING Oil may be hot after the engine has been run, and contact with hot oil can cause severe personal injury. Note: Excess oil in the foam element restricts the air flow through the element and may reach the paper filter and clog it. 12. Wipe dirt from the base and the cover with a moist rag. Avoid contacting the hot engine oil when you drain it.
Filling the Engine Crankcase with Oil 1. Remove the dipstick (Figure 28) and slowly pour oil into the fill hole until the oil reaches the upper-limit mark (bottom edge of the oil-fill hole) on the dipstick. 1 2 3 Figure 29 1. Spark plug 4 2. Wire 4. Clean around the spark plug. 5. Rotate the spark plug counterclockwise using a 13/16 inch (21 mm) spark-plug wrench to remove the plug and the sealing washer (Figure 30).

1 2 3 Servicing the Spark Arrester 4 Cleaning the Spark Arrester Service Interval: Every 100 hours Note: A spark arrester is available as an option. If you require a spark arrester, contact your Authorized Toro Service Dealer. Genuine Toro spark arresters are approved by the USDA Forestry Service. G019300 Figure 31 1. Side electrode 2.

Fuel System Maintenance Servicing the Fuel System 1 G019332 Cleaning the Sediment Cup 2 Figure 33 1. Screen Service Interval: Every 100 hours/Every 6 months (whichever comes first)—Clean the sediment cup. Yearly or before storage—Clean the fuel sediment cup. 2. Brush 6. Install the spark arrester, muffler protector, exhaust deflector, and muffler in the reverse order of disassembly. Underneath the fuel valve is a sediment cup to catch dirt in the fuel. 1.
Electrical System Maintenance 10. Move the lever of the fuel valve to the On position (all the way to the right) and check for leaks. If it leaks, replace the O-ring. Inspecting and Replacing the Fuse The engine has a fuse (Figure 35) that protects the electric-starter relay circuit and the battery-charging circuit. If the fuse burns out, the electric starter will not work. You can still start the engine with the recoil-start handle, but the engine will not charge the battery.
Replacing the Battery Charging the Battery 1. Remove the cover of the battery box. WARNING 2. Disconnect the negative (black) ground cable from the battery post. Charging the battery produces gases that can explode, seriously injuring you or bystanders. WARNING Never smoke near the battery, and keep sparks and flames away from the battery. Incorrect battery cable routing could damage the machine and cables, causing sparks. Sparks can cause the battery gases to explode, resulting in personal injury.
Checking and Cleaning the Battery Cleaning Cleaning the Machine Service Interval: Every 100 hours—Check the battery cable connections. Regular cleaning and washing will increase the life span of the machine. Clean the machine after each use, before the dirt hardens. Keep the top of the battery clean. If the machine is stored in a location where temperatures are extremely high, the battery will discharge more rapidly than if the machine is stored in a cooler location.
Storage Note: Do not install the wire on the spark plug. 10. Grease the machine; refer to Lubricating the Pump (page 19). Storing the Machine 11. Check and tighten all bolts, nuts, and screws. Repair or replace any part that is damaged. 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 dirt and debris from the outside of the engine cylinder-head fins and the blower housing. 12.
Troubleshooting Problem The engine does not start. Possible Cause 1. The fuel-valve lever is in the Off position. 1. Move the fuel-valve lever to the On position. 2. The choke is closed. 2. Open the choke when starting a hot engine. 3. Close the choke when starting a cold engine. 4. Rotate the switch to the On position. 3. The choke is open. 4. The engine On/Off switch is in the Off position. 5. The engine oil level is low (engines with the oil-level switch). 6. The fuel tank is empty. 7.
