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 Operating Practices

This product is capable of amputating hands and feet. Always follow all safety instructions to avoid serious injury or death.

POTENTIAL HAZARD

• Engine exhaust contains carbon monoxide,

which is an odorless, deadly poison.

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.

• Always wear long pants, safety glasses, safety

shoes, hearing protection, and a hard hat when operating the traction unit and any of its attachments. Other personal protective equipment 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.

WHAT CAN HAPPEN

• Carbon monoxide can kill you and is also

known to the State of California to cause birth defects.

HOW TO AVOID THE HAZARD

• Do not run engine indoors or in an enclosed

area.

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.

• Always look down and behind before and while

backing.

• 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, set the parking brake, and remove the key before leaving.

• 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 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.

Safety

• 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.

• Check for overhead clearances (i.e. branches,

doorways, electrical wires) before driving under any objects and do not contact them.

• Before digging, have the area marked for

underground utilities, and do not dig in marked areas.

• Locate the pinch point areas marked on the

traction unit and attachments and keep hands and feet away from these areas.

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 10, 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.

• 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 10, 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. Tall grass can hide obstacles.

• 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 the

tracks lose traction, proceed slowly, straight down the slope.

• Avoid turning on slopes. If you must turn, turn

slowly and keep the heavy end of the traction unit uphill.

• Do not operate near drop-offs, ditches, or

embankments. The traction unit could suddenly turn over if a track 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 setting the parking brake.

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 gasoline and other

fuels. They are flammable and vapors are explosive.

• Use only an approved container.

• 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.

Service

• Stop the engine and disconnect the spark plug

wires 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 lock.

• 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 only genuine replacement parts to ensure

that original standards are maintained.

• Battery acid is poisonous and can cause burns.

Avoid contact with skin, eyes, and clothing. Protect your face, eyes, and clothing when working with a battery.

• Battery gases can explode. Keep cigarettes,

sparks and flames away from the battery.

• Keep your body and hands away from pin hole

leaks or nozzles that eject high pressure hydraulic fluid. Use cardboard or paper to find hydraulic leaks. Hydraulic fluid escaping under pressure can penetrate skin and cause injury requiring surgery within a few hours by a qualified surgeon or gangrene may result.

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; raised arms may affect the stability.

Maximum Recommended Slope

when Operating with:

Front Uphill Rear Uphill Side Uphill

Configuration

Traction unit without attachment 11° 21° 19° Traction unit with an attachment rated with one of the following

stability ratings for each slope position:*

A B C D E

25° 25° 20° 20° 20° 18° 17° 17° 14° 10° 12° 9°

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 a 20

° slope, rearward up a 12° slope, or

sideways on a 14° slope, as listed in the above table.

Before Operating

Before operating, check the fuel and oil level, and remove debris from the traction unit. 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 Fuel

POTENTIAL HAZARD

• When fueling, under certain circumstances,

a static charge can develop, igniting the gasoline.

WHAT CAN HAPPEN

• A fire or explosion from gasoline can burn

you, others, and cause property damage.

HOW TO AVOID THE HAZARD

• 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.

POTENTIAL HAZARD

• In certain conditions gasoline is extremely

flammable and highly explosive.

WHAT CAN HAPPEN

• A fire or explosion from gasoline can burn

you, others, and cause property damage.

HOW TO AVOID THE HAZARD

• 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 gasoline (85 pump octane minimum). Leaded, regular gasoline may be used if unleaded is not available.

IMPORTANT: Do not 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.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the traction unit to provide the following benefits:

• Keeps gasoline fresh during storage of 90 days

or less. For longer storage it is recommended that the fuel tank be drained.

Check Before Operating

• Cleans the engine while it runs

• Eliminates gum-like varnish buildup in the fuel

system, which causes hard starting

IMPORTANT: Do not use fuel additives containing methanol or ethanol.

Add the correct amount of gas stabilizer/conditioner to the gas.

Note: A fuel stabilizer/conditioner is most

effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Loader Arm/Attachment Tilt Lever

To tilt the attachment forward, slowly move the lever to the right (Fig. 9).

Operation

To tilt the attachment rearward, slowly move the lever to the left (Fig. 9).

To lower the loader arms, slowly move the lever forward (Fig. 9).

To raise the loader arms, slowly move the lever rearward (Fig. 9).

You can also push the lever fully forward into a detent position (Fig. 9) to release the loader arms so that the attachment rests on the ground. This allows attachments such as the leveler and the hydraulic blade to follow the contours of the ground (i.e., float) when grading.

To operate the auxiliary hydraulics in the reverse direction using a detent position, rotate the lever rearward, then move it left into the middle slot (Fig. 10, Number 4). Only use the detent position for attachments that require it for operation, such as the Cement Bowl. To determine if an attachment requires the detent position, refer to the attachment operator’s manual.

If you release the lever while in either the forward position or upper reverse position, the lever will automatically return to the neutral position (Fig. 10, Number 1). If it is in the detent position, it will remain there until you pull it out of the slot.
