Introduction Safety Read this manual carefully to learn how to operate and maintain your product properly. The information in this manual can help you and others avoid injury and product damage. Although Toro designs and produces safe products, you are responsible for operating the product properly and safely. Improper use or maintenance by the operator or owner can result in injury.
Chemical Safety • Never allow other adults to operate the sprayer without first reading and understanding the Operator’s Manual. Only trained and authorized persons should operate this sprayer. Make sure that all operators are physically and mentally capable of operating the sprayer. Warning Chemicals are hazardous and can injure you, bystanders, animals, plants, soils, or other property. • This sprayer is designed to carry only you, the operator. Never carry any passengers on the sprayer.
– The electrical and exhaust systems of the sprayer can produce sparks capable of igniting explosive materials. Never operate the sprayer in or near an area where there is dust or fumes in the air which are explosive. – Fill the fuel tank outdoors, and fill it to about 1 inch (25 mm) below the top of the tank (the bottom of the filler neck). Do not overfill it. – Wipe up any spilled gasoline. – If you are ever unsure about safe operation, stop work and ask your supervisor.
• Be aware that heavy loads increase your stopping distance and reduce your ability to turn quickly without tipping over. • Never drive across a steep hill; always drive straight up or down or go around the hill. • If the engine stalls or you begin to lose headway while climbing a hill, gradually apply the brakes and slowly back straight down the hill. Maintenance • Turning while traveling up or down hills can be dangerous. If you have to turn while on a hill, do it slowly and cautiously.

If the oil level is low, remove the filler cap from the valve cover (Fig. 6) and pour oil into the opening until the oil level is up to the Full mark on the dipstick; refer to Servicing Engine Oil, page 33, for the proper oil type and viscosity. Add the oil slowly and check the level often during this process. Do not overfill. 7.
Recommended Gasoline Checking the Brake Fluid Use fresh, clean, unleaded regular gasoline suitable for automotive use (87 pump octane minimum). Leaded gasoline may be used if unleaded regular is not available. The brake fluid reservoir is shipped from the factory filled with DOT 3 brake fluid. Check the level before starting the engine each day.
Checking the Transaxle/Hydraulic Fluid Filling the Fresh Water Tank The sprayer is equipped with a fresh water tank (Fig. 11) for you to wash chemicals off of your skin, eyes, or other surfaces in the case of accidental exposure. Always fill the fresh water tank with clean water before handling or mixing any chemicals. 1. Position the sprayer on a level surface, set the parking brake, stop the pump, stop the engine, and remove the ignition key. 2.
Vehicle Controls Accelerator Pedal 1 The accelerator pedal (Fig. 12) gives you the ability to vary ground speed of the sprayer. Pressing the pedal increases ground speed. Releasing the pedal will slow the sprayer and the engine will idle. 2 Figure 13 1. Parking brake lever Speed Limiter 1 The speed limiter is a large knob located to the right of the seat (Fig. 14). It allows you to set the maximum downward travel of the accelerator pedal, there-by limiting the maximum speed of the sprayer.
Set the speed limiter as follows: Ignition Switch 1. Press down on the accelerator pedal to obtain the desired speed. The ignition switch (Fig. 15), used to start and stop the engine, has 3 positions: Stop, Run, and Start. Rotate the key clockwise to the Start position to start the engine and release it to the Run position when started. Rotate the key to the Stop position to stop the engine. 2.
Stopping the Engine Note: These tires are different than car tires; they require less pressure to minimize turf compaction and damage. 1. Press the brake to stop the sprayer. • Check all fluid levels and add the appropriate amount of specified fluids, if any are found to be low. 2. Pull the parking brake lever up and back to set it. • Check the brake pedal operation. 3. Move the range selector out of gear into the Neutral position. • Check to see that the lights are working. 4.
Towing the Sprayer 1 1 1 3 4 In case of an emergency, the sprayer can be towed for a short distance. However, we do not recommend this as a standard procedure. Warning 2 Towing at excessive speeds could cause a loss of steering control, resulting in personal injury. Never tow the sprayer faster than 5 mph (8 kph). Towing the sprayer is a two person job. If the machine must be moved a considerable distance, transport it on a truck or trailer; refer to Transporting the sprayer, page 19. 1.
Rate Control Valve This valve, located behind the tank (Fig. 20), controls the amount of fluid that is routed to the booms by directing fluid flow to the booms or the bypass hose to the tank. You can control this valve in two ways: the application rate switch or manually. To control it manually, you need to disconnect the wire connector on the valve, then you can rotate the knob on top of the valve to manually obtain the desired pressure. 2 1 3 1 2 m–7697 Figure 21 1. Agitation control valve 2.
Tank Drain Handle Fresh Water Tank The tank drain handle is located on top of the tank (Fig. 23). Pull the handle out to drain the tank. The fresh water tank is located at the front, left side of the tank (Fig. 25). It supplies you with a source of fresh water for you to wash chemicals off of your skin, eyes, or other surfaces in the case of accidental exposure. Always fill the fresh water tank with clean water before handling or mixing any chemicals. Important Pull the handle gently out until it stops.
Spray Prot Monitor The monitor has an LCD screen that displays the data you select, a selection dial, and 4 buttons for calibrating the monitor (Fig. 27). The Spray Pro monitor displays and monitors various system performance data such as vehicle speed and application rates. It does not control the application rate. 20 US English 20 CE Symbol m–XXXX Figure 27 1. 2. 3. 4. 5.
