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
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.

Page 4
• 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

add 1 quart of oil to raise the oil level to FULL. Do not
overfill.
3. Pour oil into the filler neck until the level is at the
FULL mark on the dipstick. The engine uses any
high-quality oil having the American Petroleum
Institute (APl) “service classification” SF or SG. The
recommended viscosity (weight) of oil to use is SAE
30.
Important The aerator operates at very high engine
loads, so check the oil level every 8 operating hours or
daily. A new engine may consume some oil until it is
broken in. Initially, change the oil after the first 25 hours of
operation; thereafter, under normal conditions, change the
We recommend the use of fresh, clean, unleaded regular
grade gasoline. Unleaded gasoline burns cleaner, extends
engine life, and promotes good starting by reducing the
build-up of combustion chamber deposits.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1 in.
(25 mm) below the bottom of the filler neck.
This empty space in the tank allows gasoline to
expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
• Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the
equipment with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
• If a gasoline dispenser nozzle must be used, keep
the nozzle in contact with the rim of the fuel
tank or container opening at all times until
fueling is complete.
Note: Do not mix oil with the gasoline. Never use
methanol, gasoline containing methanol, gasohol, gasoline
additives, premium gasoline, or white gas because engine
and fuel system damage could result.

(refer to Fluid Recommendations, page 10) to bring the
oil up to the proper level.
5. Lower the hood and secure the latches.
Checking the Gear Case Fluid
Level
The gear case, which acts as the reservoir for the hydraulic
system, is filled at the factory with approximately 4–5
quarts of Mobil DTE 26 hydraulic oil. Check the level of
hydraulic oil on the sight gauge before the engine is first
started and daily thereafter. Change the filter after the first
25 hours of operation; thereafter change the oil and filter
every 250 hours of operation.
Important The oil and filter must be changed
immediately when any contamination, sludge, water or
condensation appears in oil or on sight gauge. Determine
and correct oil contamination problem before restarting
engine and operating machine.
1. Position the machine on a level surface.
2. Release the hood latches and raise the hood.
3. Check the level of hydraulic oil on the sight gauge
(Fig. 5). The fluid level should be up to the middle of
the gauge window.
Checking the Pump Case Fluid
Level
The pump crank case is filled at the factory with
approximately 40 ounces of Mobil DTE Extra Heavy oil.
Check the oil level on the dipstick before the engine is first
started and daily thereafter. Change the oil initially after
25 hours of operation, thereafter change every 200 hours
of operation.
Important The oil must be changed immediately when
any contamination, sludge, water, or condensation appears
in the oil. Determine and correct any oil contamination
problem before restarting the engine and operating the
machine.
1. Position the machine on a level surface.
2. Release the hood latches and raise the hood.
3. Remove the dipstick/filler cap and check the oil level on
the dipstick. The fluid level should be up to the FULL
mark (Fig. 6).

Warning
Charge accumulators contain high pressure
nitrogen. Nitrogen is the only gas to use for
accumulator charging. Installing improper gases in
an accumulator can cause an explosion and death.
Charging requires special tools and precautions.
• Charge the accumulator in a well ventilated
area.
• Have the accumulator checked and charged by
an Authorized Toro Distributor.
• Wear eye protection.
• Keep your hands and face away from the gas
valve.
Figure 6
1. Dipstick/filler cap
Checking the Tire Pressure
The tires are over inflated for shipping. Make sure that the
front and rear tires are inflated to 8 to 12 p.s.i. (55 to
83 kPa).
Water System Accumulator
The Hydroject accumulator contains a high pressure
nitrogen gas pre–charge. The safety system on the aerator
will disable the water injection if the accumulator pressure
is too low or too high, and will illuminate one of the
accumulator pressure lights on the operators console.
Due to the operational requirements of the accumulator
design, the high pressure internal gas pre–charge can bleed
out during periods of inactivity. Storing the Hydroject for
extended periods of time (3 months or longer) and/or
seasonal temperature variances can affect the accumulators
ability to retain a sufficient pre–charge and seasonal
servicing (recharge) may be required.
If one of the accumulator charge indicator lamps
illuminates, contact your authorized Toro Distributor for
accumulator maintenance services.
Warning
Failure to open the bleed valve before servicing
high pressure water components can cause
personal injury, dismemberment, or death.
Slowly open the high pressure water bleed valve
before servicing any component connected to the
high pressure water system. Opening the high
pressure 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.
Note: Charged accumulators cannot be shipped via air
freight.
Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Controls
Ignition Switch
The ignition switch (Fig. 7), which is used to start and stop
the engine, has three positions: OFF, ON, and START.

Circuit Breaker Reset Button
Push the button (Fig. 7) to reset the breaker after correcting
a malfunction in the electrical system. The button also
serves as a switch to interrupt power to the relays.
Spacing Control Lever
Moving the control (Fig. 7) away from the handle increases
the aerating ground speed and the distance between holes.
Moving the control toward the handle decreases the
aerating ground speed and the distance between holes. The
setting will be overridden when the machine is shifted to
the transport position.
Traction Bail
The traction bail (Fig. 8) engages and regulates fore and aft
traction operation of the machine. Releasing the bail stops
traction operation and will also stop water injection in 3 to
4 seconds, unless the bail is engaged. The transport speed is
regulated by the amount the bail is moved.
Choke
To start the engine, close the carburetor choke by pulling
the choke control (Fig. 7) outward to the FULL position.
After the engine starts, regulate the choke to keep the
engine running smoothly. As soon as possible, open the
choke by pushing it inward to the OFF position.
Throttle
The throttle (Fig. 7) is used to regulate the engine speed.
Moving the throttle forward increases the engine speed
(FAST); rearward decreases the engine speed (SLOW).
Spray Wash Control
Pull the handle (Fig. 7) upward to activate the roller spray
wash system. Move the control knob up or down to adjust
the spray rate to keep the rollers free of debris.
Hour Meter
The hour meter (Fig. 7) registers accumulated hours of
engine operation. Use the hour meter to determine intervals
for service maintenance and lubrication.

Water Pressure Gauge
The water pressure gauge (Fig. 7) registers supply water
pressure in the system. It also acts as an interlock switch,
preventing the water pump from starting if the water
pressure is below 20–28 p.s.i., or stopping the water pump
if the water pressure drops below 7–13 p.s.i. Check the
gauge frequently to monitor the water pressure.
The switch (Fig. 8) lowers machine onto the rollers to
commence aeration. The switch will override the spacing
control setting when it is moved to the transport position.
Aeration Engagement Button
Depressing the button (Fig. 8), starts the water injection
system only when the water pressure is above 28 p.s.i. and
the rollers are on the ground.
16
Page 17
Aeration Stop Button
The red button (Fig. 8) stops the water injection system.
The system continues for a few seconds after the button is
pressed.
• Do not allow the machine to be subject to freezing
temperatures without draining, as damage to the system
will occur.
Starting and Stopping the
Parking Brake
Push the lever (Fig. 8) toward the machine to engage the
parking brake. A warning buzzer will sound if you attempt
to move the machine with parking brake engaged.
Fuel Shut-Off Valve
The fuel shut-off valve is located under the fuel tank. Close
the valve when storing or transporting (trailering) the
machine.
Operating Precautions
Follow these precautions when operating the aerator:
• Before aerating, inspect the work area for debris and
obstacles. Determine the best direction and pattern to
operate the machine. Always maintain awareness of
what lies ahead in the direction of forward travel.
• If the machine starts to vibrate abnormally, shut the
engine off. Remove the key from the ignition switch to
prevent the possibility of accidental starting. Check the
machine for damaged parts. Repair any damage before
restarting the engine and operating the machine
• Only use the aerator in daylight or when there is good
artificial light. Watch for holes or other hidden hazards.
Do not transport the machine close to a sand trap, ditch,
creek, or other hazard.
Engine
1. Make sure that the wires are installed on the spark plugs
and the fuel shut-off valve is open.
2. Make sure that the parking brake is engaged.
3. Pull the choke lever out to the FULL position and move
the throttle lever to the half throttle position.
Note: When starting a warm engine, the choke may not be
necessary, but HALF throttle is.
4. Insert the key into the ignition switch and rotate it
clockwise to start the engine. Release the key when the
engine starts. Gradually return the choke lever to the
OFF position (lever all the way in) after the engine
starts and warms up.
Important To prevent overheating of the starter motor,
do not engage the starter longer than 30 seconds. After 30
seconds of continuous cranking, wait 2 minutes before
engaging the starter motor again.
Important The engine is equipped with an oil pressure
interlock switch which interrupts the engine operation if
there is not sufficient oil pressure in the engine during
starting or operation. The engine may start but will not
continue to run due to a lack of oil pressure.
5. To stop the engine, move the throttle control downward
to the SLOW position and turn the ignition key to OFF.
Remove the ignition key.
• To prevent roller marks, always raise the machine to the
transport position when parked on a green.
• Do not operate the water injection system on concrete
or asphalt because water jets will permanently damage
these surfaces. Do not run over the hose as damage will
occur.
• Do not operate the aerator with the roller or injection
system over the edge of anything that could be hit,
damaged, or injured by high velocity water blasts.
• Water jets from the injection system should not damage
irrigation heads on one pass of the machine. Do not
allow multiple shots from the injection system to hit
irrigation heads as damage will occur.
• Use a good, clean, quality water supply in the system. If
good quality water is not available, additional filtration
equipment may be required. Do not use chemicals in
the water system.
Training Period
Before aerating with the machine, it is suggested that you
find a clear area and practice starting and stopping, raising
and lowering machine, turning, etc. This training period
will be beneficial to the operator in gaining confidence in
the performance of the aerator.
Operating Procedure
1. Make sure that the wires are installed on the spark plugs
and the fuel shut-off valve is open.
2. Uncoil a garden hose, making sure that there are no
kinks or bends in the hose. Lay out the hose so that
there are no obstructions between the machine and the
area to be aerated. Turn on the water supply to purge
any air from the hose. Turn off the water.
17
Page 18
3. Connect the hose adapter (Fig. 9) to the garden hose,
then connect the adapter to the quick coupler on the side
of the machine.
2

Figure 9
1. Hose adapter 2. Quick coupler
4. Turn on the water supply and check the water pressure.
The water pressure must be at least 30 p.s.i.. If the
system pressure is not 30 p.s.i., make sure that the hose
is not kinked or obstructed, the water supply is turned
on, and the water filter is not plugged.
5. Reach under the fuel tank and press the bleed button on
top of the water filter head (Fig. 10). Hold the bleed
button down until all air is purged from the filter and
water comes out of the opening.

8. Start the engine; refer to Starting and Stopping the
Engine, page 17. Move the throttle to the FAST position
and disengage the parking brake.
9. Engage the traction bail and approach the area to be
aerated. Make sure that there are no obstructions
between the aerator and water supply.
10. Engage and hold the transport/aerate toggle switch to
fully lower the machine onto the rollers. Release the
switch when the machine is fully lowered; then press
the engagement button to start water injection.
18
Page 19
Note: The injection operation starts approximately 4–5
seconds after the pump engages. Also, the injection system
will automatically stop if the traction bail is not engaged
within 3–4 seconds after starting the water system.
11. When aerating, work moving perpendicular from the
water supply to avoid running over the garden hose.
Use the front edge of the hood or rear corner of the
frame to align rows, if desired. When at the end of a
row, make an “S” maneuver and reverse the direction of
the aerator. Do not make sharp turns on a green or
scuffing from the tire may occur. Always maintain
awareness of what lies ahead in the direction of forward
travel.
12. Regulate the roller spray wash, if required, to remove
debris from the rollers.
Note: A small amount of water from the regulator bypass
may come out of the spray wash nozzles even with the
spray wash in the “OFF” position.
13. In areas where greater hole depth or more frequent
holes are desired, the engage button can be held down
to allow multiple shots while machine is stopped.
Important Hole depths can reach 20 inches or more
when making multiple shots, so be aware of what is buried
below the turf. Also, an excessive amount of holes and
muddy turf conditions may occur when making multiple
shots.
14. To stop water injection, press the red button. The
system continues for a few seconds after the button is
pressed. Raise the machine to the transport position,
disconnect the supply hose, and move to the next
location.
Checking the Interlock System
Caution
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly,
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
• Replace switches every two years regardless of
whether they are operating properly or not.
To do a functional check of interlock system:
1. Position the machine in a flat, open area on rough turf
and away from buried wires, plumbing, etc. Stop the
engine.
2. Move the traction bail up and down while trying to start
the engine. If the engine cranks, there is a malfunction
in the interlock system that must be corrected. If the
engine does not crank, proceed to step 3.
3. Connect the water supply to the machine. Turn on the
water supply and bleed all air out of the system. The
water pressure must be 30 psi or more. Start the engine.
Raise the machine to the transport position (up off the
rollers). Push the aerate ENGAGE button. If the water
pump engages and the machine begins aerating, there is
a malfunction in the interlock system that must be
corrected. If the machine does not begin aerating,
proceed to step 4.
4. Lower the machine to the aerate position (on the
rollers). Engage the traction bail to start the machine
moving. Push, then release the aerate ENGAGE button.
The water pump should engage immediately, then the
machine should begin aerating 5 seconds after the pump
engages. Release the traction bail to the neutral position
so that the machine stops moving. The water pump
should disengage 4 seconds after the traction bail
returns to neutral, then stop aerating after another 3
seconds. If the machine does not stop aerating when the
traction bail returns to neutral, there is a malfunction in
the interlock system that must be corrected. If the
machine stops aerating, proceed to step 5.
5. Engage the traction bail to start the machine moving,
then push the aerate ENGAGE button to begin aerating.
Push the aerate DISENGAGE button. The water pump
should disengage immediately, then stop aerating after 3
seconds. If the machine does not stop aerating, there is a
malfunction in the interlock system that must be
corrected.
Note: Lights (LED’s) on the controller (Fig. 13) indicate
when the following inputs are made to the controller:

The purpose of the safety interlock system is to prevent the
engine from cranking or starting unless the traction bail is
in NEUTRAL and prevents the water system from
engaging if the machine is in the transport (raised) position.
It also stops aeration if the traction bail is released while
operating or if the machine is raised to the transport
position.

Transport Operation
1
Use the traction bail to slow the machine while crossing
undulating terrain to avoid loss of control. The smooth tires
do not grip turf very well so use caution when transporting
the machine. Always approach rough areas at a reduced
speed and cross severe undulations carefully.
Inspection and Clean-Up After
Use
At the completion of operation, thoroughly wash the
machine with a garden hose without a nozzle so excessive
water pressure will not cause contamination and damage to
seals and bearings. After cleaning, it is recommended the
machine be inspected for possible hydraulic fluid or water
leaks and damage or wear to hydraulic, water, and
mechanical components.
Pushing or Towing the Machine
In an emergency, the machine can be pushed or towed for a
very short distance. However, we do not recommend this as
standard procedure.
Important Do not push or the tow machine faster than
3 MPH because pump damage may occur. If the machine
must be moved a considerable distance, transport it on a
truck or trailer or pull it with the traction wheel raised and
secured to a dolly. Whenever the machine is pushed or
towed, the bypass valve must be opened. The hook on the
front of the handle is used as a tie-down only, not a hitch
point.

1. Unlatch and raise the hood.
2. Locate the bypass valve cap on the left side of the
hydraulic pump (Fig. 14).
3. Rotate the valve cap counterclockwise, move the
machine to the desired location, and close the valve cap.
4. Lower the hood and secure the latches.
Important Do not run any chemicals through the
Hydroject water system (except Toro Wetting Agent
86–8530). Chemicals can have corrosive effects on
machine components and environmental laws and concerns
exist when injecting chemical sub–surface.

Replacing the Main Water Filter
The machine is a precision piece of equipment and the
quality or cleanliness of your water supply is very
important in determining the life of the machine. If your
water supply contains silt, sand, or other debris, you may be
required to install additional filtration or separation
equipment between your supply source and the machine.
Depending on the quality of water, the frequency of the
filter change will vary greatly. When the pump inlet
pressure decreases or the water system shuts down, it
usually means the water filter is restricted and must be
replaced. Never operate machine without a water filter
as severe damage may occur.
1. Position the machine on a level surface and make sure
that the engine is shut off. Shut off the water supply.
2. Locate the main water filter assembly mounted below
the fuel tank. Press the bleed button (Fig. 19) to release
air pressure from the filter body.

Caution
The water filter body is very heavy when filled
with water and the filter. Use caution when
unscrewing the filter body from the filter head.
4. Thoroughly rinse out the filter body to avoid
contaminating the water system. Make sure that the
o-ring (Fig. 19) is in the groove. If it has come out,
wipe it dry, lubricate it with a light coating of petroleum
jelly, and replace it in the groove.
5. Thoroughly clean the filter head mounting surface to
avoid contaminating the water system when the filter is
installed.
6. Insert the new filter cartridge into the filter body.
7. Thread the filter body with the filter onto the filter head.
Hand tighten them.
8. Turn on the water supply and press the bleed button on
the top of the water filter head (Fig. 19). Hold the bleed
button down until all air is purged from the filter and
water comes out of the opening.

Changing the Engine Oil and
Filter
For new engines, change the oil after the first 25 operating
hours. Thereafter, under normal conditions, change the oil
and filter after every 100 hours of operation. However, an
engine operated in dusty or dirty conditions requires more
frequent oil changes. If possible, run the engine just before
changing the oil. Warm oil flows more freely and carries
more contaminants than cold oil.
1. Position the machine on a level surface.
2. Disengage the hood latches and open the hood.
3. Place an oil drain pan below the drain cap on the
bottom of the crankcase (Fig. 20). Clean the area
around the drain cap.
4. Remove the drain cap and allow oil to flow into a drain
pan. After the oil has drained, install the oil drain cap.

6. Apply a thin film of clean oil to the gasket. Install a
new filter by hand until the gasket just touches the
mounting surface, then turn the filter an additional 1/2
to 3/4 turn.
7. Remove the filler cap (Fig. 22) and pour approximately
3 quarts of oil having the API “service classification”
SF or SG into the filler neck. The recommended
viscosity (weight) of oil to use is SAE 30.

3. Pull the wires off of the spark plugs and remove the
plugs from the cylinder head.
4. Check the condition of the center and side electrodes to
determine the operating temperature of the engine.
• Light brown insulator tip indicates correct spark plug
and heat range.
• Black or oily insulator tip indicates an excessively rich
fuel mixture, possibly caused by a dirty air cleaner
element or a carburetor that is set too rich.
• Light gray or blistered-white insulator indicates
overheating caused by a lean carburetor setting or
incorrect spark plug (heat range too high).
Important A cracked, fouled, or dirty spark plug must
be replaced. Do not sandblast, scrape, or clean the
electrodes by using a wire brush because grit may release
from the plug and enter the combustion chamber, resulting
in engine damage.

and the top of the battery kept clean. If the aerator is stored
in a location where temperatures are extremely high, the
battery will run down more rapidly than if the machine is
stored in a location where temperatures are cool.
Check the electrolyte level every 50 operating hours or, if
the machine is in storage, every 30 days.
Maintain the cell level with distilled or de-mineralized
water. Do not fill the cells above the bottom of the split ring
inside each cell.
Keep the top of the battery clean by washing it periodically
with a brush dipped in ammonia or bicarbonate of soda
solution. Flush the top surface with water after cleaning.
Do not remove the fill caps while cleaning.
The battery cables must be tight on the terminals to provide
good electrical contact.
Servicing the Spray Wash
Nozzles or Strainers
To clean or replace the strainers in the spray wash nozzles,
proceed as follows:
1. Loosen and remove the cap on the bottom of the fitting
(Fig. 38).
2. Remove the nozzle and strainer assembly (Fig. 38).
Clean or replace the strainer and replace it in the nozzle.
3. Loosely secure the nozzle and strainer to the fitting with
the cap.
4. Rotate the nozzle so that slot in the tip is parallel to the
roller.
5. Tighten the cap and check the adjustment.
If corrosion occurs at the terminals, disconnect the cables,
negative (–) cable first, and scrape the clamps and terminals
separately. Reconnect the cables, positive cable first, and
coat the terminals with petroleum jelly.
Warning
Incorrect battery cable routing could damage the
aerator and cables causing sparks. Sparks can
cause the battery gasses to explode, resulting in
personal injury.
• Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.
• Always connect the positive (red) battery cable
before connecting the negative (black) cable.
If the machine will be stored more than 30 days, remove
the battery and charge it fully. Either store it on the shelf or
on the machine. Leave the cables disconnected if it is stored
on the machine. Store the battery in a cool atmosphere to
avoid quick deterioration of the charge in the battery.

Parts
Parts scheduled for replacement as required maintenance are
warranted for the period of time up to the scheduled replacement
time for that part.
Parts replaced under this warranty become the property of Toro.
Toro will make the final decision whether to repair any existing part
or assembly or replace it. Toro may use factory remanufactured
parts rather than new parts for some warranty repairs.
General Conditions
Repair by an Authorized Toro Distributor or Dealer is your sole
remedy under this warranty.
Neither The Toro Company nor Toro Warranty Company is
liable for indirect, incidental or consequential damages in
connection with the use of the Toro Products covered by this
warranty, including any cost or expense of providing substitute equipment or service during reasonable periods of
malfunction or non-use pending completion of repairs under
this warranty. Except for the Emissions warranty referenced
below, if applicable, there is no other express warranty. All
implied warranties of merchantability and fitness for use are
limited to the duration of this express warranty.
Some states do not allow exclusions of incidental or consequential
damages, or limitations on how long an implied warranty lasts, so
the above exclusions and limitations may not apply to you.
This warranty gives you specific legal rights, and you may also
have other rights which vary from state to state.
Note regarding engine warranty: The Emissions Control
System on your Product may be covered by a separate warranty
meeting requirements established by the U.S. Environmental
Protection Agency (EPA) and/or the California Air Resources
Board (CARB). The hour limitations set forth above do not apply to
the Emissions Control System Warranty. Refer to the Engine
Emission Control Warranty Statement printed in your operator’s
manual or contained in the engine manufacturer’s documentation
for details.
Countries Other than the United States or Canada
Customers who have purchased Toro products exported from the United States or Canada should contact their Toro Distributor (Dealer)
to obtain guarantee policies for your country, province, or state. If for any reason you are dissatisfied with your Distributor’s service or
have difficulty obtaining guarantee information, contact the Toro importer. If all other remedies fail, you may contact us at Toro Warranty
Company.
