signal words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
Danger signals an extreme hazard that will cause serious
injury or death if you do not follow the recommended
precautions.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
This manual uses two other words to highlight information.
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

• 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.
3
• 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 partsand 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
