Safety
Improper use or maintenance by the operator or
owner can result in injury. To reduce the potential
for injury, comply with these safety instructions
and always pay attention to the safety alert
symbol, which means CAUTION, WARNING, or
DANGER—“personal safety instruction.” Failure
to comply with the instruction may result in
personal injury or death.
Safe
This product is capable of amputating hands and feet.
Always follow all safety instructions to avoid serious
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.
•
Always wear long pants and substantial shoes.
Wearing safety glasses, safety shoes, 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.
• 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.
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.
2
• 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.
• 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.
Safety
• 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.
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 11, and those in the
attachment operator’s manual. See also the
slope chart on page 5.
• 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 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.
• 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.
• 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 11, 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.
• 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.

Safety
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.
• 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.
• Use extra care when handling fuel. It is
flammable and vapors are explosive.
• Use only an approved container.
• Never remove the fuel 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.
Service
• Stop the engine before performing any service,
repairs, maintenance, or adjustments.
• 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

Check Before Operating
Stability
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.
Maximum Recommended Slope
when Operating with:
Front Uphill
Configuration
T
raction unit without attachment
T
raction unit with counterweight, without attachment
T
raction unit with an attachment rated with one of the following
stability ratings for each slope position:*
A 25° 25° 20°
B 18° 19° 18°
7° 20° 17°
5° 21° 17°
Rear Uphill
Side Uphill
C 15° 16° 14°
D 10° 10° 9°
E 5° 5° 5°
* In each attachment manual is a set of three stability ratings, one for each hill position. To determine the
maximum slope you can traverse with the attachment installed, find the degree of slope that corresponds to the
stabilities ratings of the attachment.
Example: If the attachment installed on the traction unit has a Front Uphill rating of B, a Rear Uphill rating of
D, and a Side Uphill rating of C, then you could drive forward up an 18
° slope, rearward up a 10° slope, or
sideways on a 14° slope, as listed in the above table.
11
Before Operating
Before operating, check the fuel and oil level, remove
debris from the traction unit, and check the tire
pressure. Also, ensure that the area is clear of people
and debris. You should also know and have marked
the locations of all utility lines.
Adding
The engine runs on clean, fresh diesel fuel with a
minimum cetane rating of 40. Purchase fuel in
quantities that can be used within 30 days to ensure
fuel freshness.
Use summer grade diesel fuel (No. 2–D) at
temperatures above 20 F (–7 C) and winter grade
diesel fuel (No. 1–D or No. 1–D/2–D blend) below
20 F (–7 C). Use of winter grade diesel fuel at
lower temperatures provides lower flash point and
pour point characteristics, allowing easier starts and
lessening the chances of chemical separation of the
fuel due to lower temperatures.
Use of summer grade diesel fuel above 20 F (–7 C)
will contribute toward longer life of the fuel pump
components.
IMPORTANT: Do not use ker
gasoline in place of diesel fuel. Failure to
observe this caution will damage the engine.
1. Park the traction unit on a level surface, lower
the loader arms, and stop the engine.
Fuel
osene or
5. Install the fuel tank cap securely. Wipe up any
fuel that may have spilled.
If possible, fill the fuel tank after each use. This will
minimize possible buildup of condensation inside the
fuel tank.
POTENTIAL HAZARD
• Under certain conditions fuel is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
• A fire or explosion from fuel can burn you,
others, and cause property damage.
HOW TO AV
OID THE HAZARD
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any fuel
that spills.
• Do not fill the fuel tank completely full.
Add fuel to the fuel tank until the level is
1/4 to 1/2 in. (6 to 13 mm) below the bottom
of the filler neck. This empty space in the
tank allows fuel to expand.
• Never smoke when handling fuel, and stay
away from an open flame or where fuel
fumes may be ignited by a spark.
• Store fuel in an approved container and
keep it out of the reach of children. Never
buy more than a 30-day supply.
2. Remove the key and allow the engine to cool.
3. Clean around the fuel tank cap and remove the
cap.
4. Use a funnel and add diesel fuel to the fuel tank,
until the level is 1/4 to 1/2 inch (6 mm to
13 mm) below the bottom of the filler neck.
Note: This space in the tank allows fuel to
expand. Do not fill the fuel tank
completely full.
