injury or death.
Operating Practices
POTENTIAL HAZARD
• Engine exhaust contains carbon monoxide,
which is an odorless, deadly poison.
WHAT CAN HAPPEN
• Carbon monoxide can kill you and is also
known to the State of California to cause
birth defects.
HOW TO AV
OID THE HAZARD
• Do not run engine indoors or in an enclosed
area.
General Operation
• Read, understand, and follow all instructions in
the operator’s manual, in the video, and on the
traction unit before starting. Also, read all
attachment manuals where supplied
• Allow only responsible adults who are familiar
with the instructions to operate the traction unit.
• Do not operate the traction unit or attachments
while wearing sandals, tennis shoes, sneakers, or
shorts. Always wear long pants and substantial
shoes. W
hearing protection, and a hard hat are advisable
and may be required by some local ordinances
and insurance regulations.
• Ensure that the area is clear of other people
before operating the traction unit. Stop the
traction unit if anyone enters the area.
• Never carry passengers on attachments or on the
traction unit.
• Always look down and behind before and while
backing.
• Do not place your feet under the platform.
• Slow down before turning. Sharp turns on any
terrain may cause loss of control.
earing safety glasses, safety shoes,
Because in some areas there are local, state, or federal
regulations requiring that a spark-arrester be used on
engines, a spark-arrester is available as an option for
the traction unit. If a spark-arrester is required,
contact your Toro dealer. Genuine Toro approved
spark-arresters are approved by the USDA Forestry
Service. It is a violation of the State of California
PRC Section 4442 to use or operate the engine on any
forest-covered, brush-covered, or grass-covered land,
unless the engine is equipped with a spark-arrester,
maintained in working order, or the engine is
constricted, equipped, and maintained for the
prevention of fire.
2
• Never leave a running traction unit unattended.
Always lower the loader arms, stop the engine,
and remove the key before dismounting.
• Do not exceed the rated operating capacity, as
the traction unit may become unstable which
may result in loss of control.
• Do not carry a load with the arms raised. Always
carry loads close to the ground. Do not step off
of the platform with the load raised.
Page 5
Safety
• Do not over-load the attachment and always
keep the load level when raising the loader arms.
Logs, boards, and other items could roll down
the loader arms, injuring you.
• Never jerk the control levers; use a steady
motion.
• Keep your hands, feet, hair, and loose clothing
away from any moving parts.
• Operate only in daylight or good artificial light.
• Do not operate the traction unit while under the
influence of alcohol or drugs.
• Watch for traffic when operating near or crossing
roadways.
• Use extra care when loading or unloading the
traction unit onto a trailer or truck.
• Do not touch parts which may be hot from
operation. Allow them to cool before attempting
to maintain, adjust, or service.
• Raising the loader arms on a slope will affect the
stability of the machine. Whenever possible,
keep the loader arms in the lowered position
when on slopes.
• Removing an attachment on a slope will make
the rear of the traction unit heavy. Refer to the
Stability Data section, page 12, to determine
whether the attachment can be safely removed
on the slope.
• Remove obstacles such as rocks, tree limbs, etc.
from the work area. Watch for holes, ruts, or
bumps, as uneven terrain could overturn the
traction unit. T
all grass can hide obstacles.
• Use slow speed on slopes. Before starting the
engine, put the pump selector lever in the slow
(turtle) position so that you will not have to stop
or shift while on the slope.
• Follow the recommendations in the attachment
manuals for the use of counterweights to
improve stability.
Slope Operation
Slopes are a major factor related to loss-of-control
and tip-over accidents, which can result in severe
injury or death. All slopes require extra caution.
• Do not operate the traction unit on hillsides or
slopes exceeding the angles recommended in the
Stability Data section, page 12, and those in the
attachment operator’s manual. See also the
slope chart on page 6.
• Operate up and down slopes with the heavy
end of the traction unit uphill. Weight
distribution changes. An empty bucket will make
the rear of the traction unit the heavy end, and a
full bucket will make the front of the traction
unit the heavy end. Most other attachments will
make the front of traction unit the heavy end.
• Use only Toro approved attachments.
Attachments can change the stability and the
operating characteristics of the traction unit.
Warranty may be voided if used with
unapproved attachments.
• Keep all movements on slopes slow and gradual.
Do not make sudden changes in speed or
direction.
• Avoid starting or stopping on a slope. If tires
lose traction, proceed slowly, straight down the
slope.
• Check for overhead clearances (i.e. branches,
doorways, electrical wires) before driving under
any objects and do not contact them.
• Avoid turning on slopes. If you must turn, turn
slowly and keep the heavy end of the traction
unit uphill.
3
Page 6
Safety
• Do not operate near drop-offs, ditches, or
embankments. The traction unit could suddenly
turn over if a wheel goes over the edge of a cliff
or ditch, or if an edge caves in.
• Do not operate on wet grass. Reduced traction
could cause sliding.
• Do not park the traction unit on a hillside or
slope without lowering the attachment to the
ground and chocking the wheels.
• Do not try to stabilize the traction unit by putting
your foot on the ground.
Children
Tragic accidents can occur if the operator is not alert
to the presence of children. Children are often
attracted to the traction unit and the work activity.
Never assume that children will remain where you
last saw them.
• If any maintenance or repair requires the loader
arms to be in the raised position, secure the arms
in the raised position with the hydraulic cylinder
locks included with traction unit.
• Never run a traction unit inside a closed area.
• Keep nuts and bolts tight. Keep equipment in
good condition.
• Never tamper with safety devices. Check safety
systems for proper operation before each use.
• Keep the traction unit free of grass, leaves, or
other debris build-up. Clean up oil or fuel
spillage. Allow the traction unit to cool before
storing.
• Use extra care when handling gasoline and other
fuels. They are flammable and vapors are
explosive.
• Use only an approved container.
• Keep children out of the work area and under the
watchful care of another responsible adult.
• Be alert and turn the traction unit off if children
enter the area.
• Before and while backing, look behind and down
for small children.
• Never carry children. They may fall off and be
seriously injured or interfere with safe traction
unit operation.
• Never allow children to operate the traction unit.
• Use extra care when approaching blind corners,
shrubs, trees, the end of a fence, or other objects
that may obscure vision.
Service
• Stop the engine and disconnect the spark plug
wires before performing any service, repairs,
maintenance, or adjustments.
• Never remove the gas cap or add fuel when
the engine is running. Allow the engine to
cool before refueling. Do not smoke.
• Never refuel the traction unit indoors.
• Never store the traction unit or fuel
container inside where there is an open
flame, such as near a water heater or
furnace.
• Never fill a container while it is inside a
vehicle, trunk, pick–up bed, or any surface
other than the ground.
• Keep container nozzle in contact with the
tank during filling.
• Stop and inspect the equipment if you strike an
object. Make any necessary repairs before
restarting.
• Use only genuine replacement parts to ensure
that original standards are maintained.

Data
The following table lists the maximum slope recommended for the traction unit in the positions listed in the
table. Slopes over the listed degree may cause the traction unit to become unstable. The data in the table
assumes that the loader arms are fully lowered and that the factory installed tires are on the traction unit, inflated
to the recommended pressure; raised arms and other tire types or pressure may affect the stability.

ed
• 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.
HOW TO AV
OID THE HAZARD
• Use a funnel and 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 1/4” to 1/2” (6 mm to 13 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.
Use unleaded regular gasoline (85 pump octane
minimum). Leaded regular gasoline may be used if
unleaded regular is not available.
IMPORTANT: Never use methanol, gasoline
containing methanol, or gasohol containing
more than 10% ethanol because the fuel
system could be damaged. Do not mix oil with
gasoline.
IMPORTANT: Never use fuel additives
containing methanol or ethanol.
Note: The two fuel tanks will run empty
equally; however, you must fill them
separately because filling one will not
fill the other.

Key Switch
The key switch, used to start and stop the engine, has
three positions: off, run, and start.
To start the engine, rotate the key to the start position.
Release the key when engine starts and it will move
automatically to the run position.
Traction Control Levers
To move forward, move the traction control levers
forward. To move rearward, move the traction control
levers rearward.
To go straight, move both traction control levers
equally.
To turn, move the lever located on the side you want
to turn back toward the neutral position while keeping
the other lever engaged.
The farther you move the traction control levers in
either direction, the faster the traction unit will move
in that direction.
To slow or stop, move the traction control levers to
neutral.
Attachment Tilt Lever
To tilt the attachment forward, slowly push the
attachment tilt lever forward.
To tilt the attachment rearward, slowly pull the
attachment tilt lever rearward.
Loader Arm Lever
To stop the engine, rotate the key to the off position.
Throttle Lever
Move the control forward to increase the engine
speed and rearward to decrease speed.
Choke Lever
Before starting a cold engine, move the choke lever
fully forward. After the engine starts, regulate the
choke to keep the engine running smoothly. As soon
as possible, move the choke lever rearward as far as
possible. A warm engine requires little or no choking.
To lower the loader arms, slowly push the loader arm
lever forward.
To raise the loader arms, slowly pull the loader arm
lever rearward.
Auxiliary Hydraulics Lever
To operate a hydraulic attachment in forward
direction, slowly pull the auxiliary hydraulics lever
rearward.

Page 20
Operation
Pump Selector Lever
Move the pump selector lever to the fast (rabbit)
position to set the traction drive, loader arms, and
attachment tilt to high speed and the auxiliary
hydraulics to low speed.
Move the pump selector lever to the slow (turtle)
position to set the auxiliary hydraulics to high speed
and the traction drive, loader arms, and attachment tilt
to low speed.
POTENTIAL HAZARD
• If the pump selector lever is moved while
the traction unit is in motion, the traction
unit will either stop suddenly or accelerate
quickly.
• If the traction unit is operated with the
pump selector lever in an intermediate
position, the traction unit will operate
erratically and may be damaged.
WHAT CAN HAPPEN
• You could be thrown forward or
backwards, resulting in injury.
• If the traction unit accelerates quickly, you
could loose control of the traction unit and
injure bystanders or yourself.
• You could loose control of the traction unit,
severely injuring yourself or others.
• The traction unit could be damaged.
HOW TO AV
OID THE HAZARD
• Do not move the pump selector lever when
the traction unit is in motion.
• Do not operate the traction unit when the
speed selector is in any intermediate
position (i.e., any position other than fully
forward or fully rearward).
Flow Divider Control
The traction unit hydraulics (i.e., the traction drive,
loader arms, and attachment tilt) work on a separate
hydraulic circuit from the auxiliary hydraulics for
powering attachments; however, the two systems
share the same hydraulic pumps. Using the flow
divider control (Fig. 10), you can vary the speed of
the traction unit hydraulics by diverting hydraulic
flow to the auxiliary hydraulics circuit. The flow
divider allows you to divide the flow of fluid in
varying degrees to slow the traction unit. Thus, the
more hydraulic flow you divert to the auxiliary
hydraulics, the slower the traction unit hydraulics will
move.

Use this setting for fast operation of the traction
unit.
• Move the flow divider control between the
twelve–o’clock and nine–o’clock positions to
slow the traction unit hydraulics and fine tune
the speed.
Use a setting in this range with attachments with
hydraulics where you need to both run the
attachment and move the traction unit
hydraulics, such as the auger, boring unit,
hydraulic blade, and tiller.
• Move the control to the nine–o’clock position to
transfer all hydraulic flow to the auxiliary
hydraulics of the attachment.
In this setting, the traction unit hydraulics will
not work. Use this setting with hydraulic
attachments that do not required the traction unit
hydraulics. There are currently no attachments
18
Page 21
Operation
that require the nine–o’clock position; however,
the trencher does work best if you set it close to
nine–o’clock so that the traction unit will creep
slowly when trenching.
Note: The flow divider control can be fixed
in place by turning the knob on the
control clockwise until it contacts the
dial (Fig. 10).
Starting
and Stopping the
Engine
Starting the Engine
1. Stand on the platform.
2. Move the auxiliary hydraulics valve lever to
neutral.
3. Move the throttle lever midway between slow
(turtle) and fast (rabbit) positions.
4. Move the choke lever fully forward before
starting a cold engine.
Note: A warm or hot engine may not require
choking.
5. Turn the ignition key to the start position. When
the engines starts, release the key.
IMPORTANT: Do not engage the starter for
more than 10 seconds at a time. If the engine
fails to start, allow a 30 second cool-down
period between attempts. Failure to follow
these instructions can burn out the starter
motor.
6. After the engine starts, gradually move the choke
to rearward. If the engine stalls or hesitates,
move the choke forward again until the engine
warms up.
IMPORTANT: If the engine is run at high
speeds when the hydraulic system is cold (i.e.,
when the ambient air temperature is around
freezing or lower), hydraulic system damage
could occur. When starting the engine in cold
conditions, allow the engine to run in the
middle throttle position for 2 to 5 minutes
before moving the throttle to fast (rabbit).
Stopping the Engine
1. Move the throttle lever to the slow (turtle)
position.
2. Lower the loader arms to the ground.
3. Turn the ignition key off.
Note: If the engine has been working hard or
is hot, let it idle for a minute before
turning the ignition key off. This helps
cool the engine before it is stopped. In
an emergency, the engine may be
stopped immediately
Driving
The throttle control regulates the engine speed as
measured in rpm (revolutions per minute). Place the
throttle lever in the fast (rabbit) position for best
performance.
Note: Throttle position can be utilized to

leaks, never use your hands.
Servicing
Check the electrolyte level in the battery every 100
hours. Always keep the battery clean and fully
charged. Use a paper towel to clean the battery case.
If the battery terminals are corroded, clean them with
a solution of four parts water and one part baking
soda. Apply a light coating of grease to the battery
terminals to reduce corrosion.

Checking Hydraulic Lines
After every 100 operating hours, check the hydraulic
lines and hoses for leaks, loose fittings, kinked lines,
loose mounting supports, wear, weather, and chemical
deterioration. Replace all moving hydraulic hoses
every 1500 hours or 2 years, which ever comes first.
Make necessary repairs before operating.

2. If the electrolyte is low, add the required amount
of distilled water; refer to Adding Water to the
Battery, below.
Adding Water to the Battery
The best time to add distilled water to the battery is
just before you operate the traction unit. This lets the
water mix thoroughly with the electrolyte solution.
1. Clean the top of the battery with a paper towel.
2. Remove the filler caps from the battery and
connect a 3 to 4 amp battery charger to the
battery posts. Charge the battery at a rate of 4
amperes or less for 4 hours (12 volts). Do not
overcharge the battery.
3. Install the filler caps after the battery is fully
charged.
POTENTIAL HAZARD
• Charging the battery pr
oduces gasses.
WHAT CAN HAPPEN
• Battery gasses can explode.
HOW TO AV
OID THE HAZARD
• Keep cigarettes, sparks, and flames away
from the battery.
