Important calls attention to special mechanical
information and Note: emphasizes general information worthy of special attention.
Safety
Hazard control and accident prevention are dependent upon the awareness, concern, and proper training of the personnel involved in the operation, transport, maintenance, and storage of the machine. Improper use or maintenance of the machine can result in injury or death. To reduce the potential for injury or death, comply with the following safety instructions.
Keep all shields and safety devices in place. If a shield, safety device, or decal is damaged, repair or replace it before operation is commenced. Also tighten any loose nuts, bolts, and screws to ensure that the machine is in safe operating condition.
Do not operate machine while wearing sandals, tennis shoes, sneakers, or shorts. Also, do not wear loose fitting clothing which could get caught in moving parts. Always wear long pants and substantial shoes. Wearing safety glasses, safety shoes, ear protection, and a helmet is advisable and required by some local ordinances and insurance regulations.
Fill the fuel tank with gasoline before starting the engine. Avoid spilling gasoline. Since gasoline is flammable, handle it carefully.
– Use an approved gasoline container.
– Do not fill the tank while the engine is hot or
running.
– Do not smoke while handling gasoline.
– Fill the fuel tank outdoors and up to about one in.
(25 mm) from the top of the tank, not the filler neck.
– Wipe up any spilled gasoline.
Check the interlock switches daily for proper operation. If a switch fails, replace it before operating the machine. The interlock system is for your protection, so do not bypass it. Replace all interlock switches every two years.
Before Operating
Read and understand the contents of this Operator’s Manual before operating the machine. Become familiar with all of the controls and know how to stop quickly. A free replacement manual is available by sending your complete Model and Serial Number to:
The Toro Company 8111 Lyndale Avenue South Bloomington, Minnesota 55420
Never allow children to operate the machine. Do not allow adults to operate the machine without proper instruction. Only trained operators who have read this manual should operate this machine.
Never operate the machine when under the influence of drugs or alcohol.
While Operating
Do not take an injury risk! When a person or pet appears unexpectedly in or near the working area, stop
aerating.
Keep hands and feet away from the nozzle and roller area. High velocity water jets can penetrate hands and feet. Penetration by the high velocity water jets can cause serious personal injury. If accidental penetration occurs, seek medical attention immediately.
Never use chemicals in the water supply system.
Do not operate the water injection system on concrete
or asphalt because water jets will permanently damage these surfaces.
Start the engine with the parking brake engaged.
Do not run the engine in a confined area without adequate ventilation. Exhaust fumes are hazardous and could possibly be deadly.
Using the machine demands attention. To prevent loss of control:
– Use only in daylight or when there is good artificial
light.
– Watch for holes or other hidden hazards.
– Do not transport machine close to a sand trap, ditch,
creek, or other hazard.
If the machine starts to vibrate abnormally, shut the engine off. Remove the wires from the spark plugs to prevent possibility of accidental starting. Check the machine for damaged parts. Repair any damage before restarting the engine and operating the machine.
search for leaks. Hydraulic fluid or water escaping under pressure can have sufficient force to penetrate skin and do serious damage. If either of these fluids are injected into the skin they must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.
Before disconnecting or performing any work on the hydraulic oil system, all pressure in the system must be relieved by stopping the engine and opening the bypass valve.
Before disconnecting or performing any work on the water system, all pressure in the system must be relieved by stopping the engine and opening the bleed valve. Opening the bleed valve allows any trapped water to escape from the system and also allows the accumulator piston to move to the bottom of the accumulator cylinder.
Do not touch the engine or muffler while the engine is running or soon after it is stopped. These areas could be hot enough to cause a burn.
Before leaving the operator’s position (behind the handle), engage the parking brake.
When leaving the machine unattended, engage the parking brake, shut the engine OFF, and remove the key from the ignition switch.
Maintenance
Disconnect the wires from the spark plugs to prevent accidental starting of the engine when servicing, adjusting, or storing the machine.
If the machine must be tipped to perform maintenance or an adjustment, close the fuel shut-off valve, drain the gasoline from the fuel tank, the oil from the crankcase, and remove the battery.
To reduce the potential for a fire hazard, keep the engine free of excessive grease, grass, leaves, and accumulation of dirt.
Be sure that the machine is in safe operating condition by keeping nuts, bolts, and screws tight. Check all bolts and nuts frequently to be sure that they are tightened to specification.
If the engine must be running to perform a maintenance adjustment, keep hands, feet, clothing, and other parts of the body away from any moving parts.
Make sure that all hydraulic line connectors are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system.
The accumulator in this machine contains high pressure dry nitrogen. Accumulator servicing requires special tools and precautions. Accumulators do not contain user serviceable components. Improper accumulator servicing can cause dismemberment or death. Do not attempt to disassemble a accumulator; have this work done by an Authorized Toro Distributor.
Do not overspeed the engine by changing the governor settings. To be sure of safety and accuracy, have an Authorized Toro Distributor check the maximum engine speed with a tachometer.
The engine must be shut off before checking the oil or adding oil to the crankcase.
Allow the engine to cool before storing the machine in any enclosure such as a garage or storage shed. Make sure that the fuel tank is empty if the machine is to be stored in excess of 30 days. Do not store the machine near any open flame or where gasoline fumes may be ignited by a spark. Always store gasoline in a safety approved, red metal container.
When storing or transporting the machine (trailering), make sure that the fuel shut-off valve is closed.
Perform only those maintenance instructions described in this manual. If major repairs are ever needed or assistance is desired, contact an Authorized Toro Distributor. To ensure optimum performance and safety, always purchase genuine Toro replacement parts and accessories. Never use “will-fit” replacement parts and accessories made by other manufacturers. Look for the Toro logo to ensure genuineness. Using unapproved replacement parts and accessories could void the warranty.
Keep your body and hands away from pin hole leaks or nozzles that eject water or hydraulic fluid under high pressure. Use paper or cardboard, not your hands, to
