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.

• 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 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.

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

raction unit without attachment

raction unit with counterweight, without attachment

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.

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.

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 a forward direction, slowly pull the auxiliary hydraulics lever rearward.

Move the control forward to increase the engine speed and rearward to decrease speed.

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 operate a hydraulic attachment in a reverse direction, slowly push the auxiliary hydraulics lever forward.

Speed Selector Lever

Move the speed 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.

Operation

Move the speed 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 speed 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

speed 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 speed 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. 13), 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.

Note: The flow divider position (i.e., 9–12

o’clock) is determined when standing in the normal operator’s position. Figure 13 shows the flow divider from the front.

• Move the flow divider control to the

twelve–o’clock position to provide maximum speed to the traction unit hydraulics.

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 that require the nine–o’clock position; however,

Operation

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. 13).

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.

POTENTIAL HAZARD

• Hydraulic fluid escaping under pressure

can penetrate skin and cause injury.

WHAT CAN HAPPEN

• Fluid accidentally injected into the skin

must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

HOW TO AV

OID THE HAZARD

• Keep body and hands away from pin hole

leaks or nozzles that eject high pressure hydraulic fluid.

• Use cardboard or paper to find hydraulic

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.

3. 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.

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.

3. Install the filler caps after the battery is fully

charged.

4. Replace the battery cover.

2. Lift off the filler caps (Fig. 31).

3. Slowly pour distilled water into each battery cell

until the level is up to the lower part of the tube (Fig. 31).

IMPORTANT: Do not overfill the battery because electr sever

e corr

olyte (sulfuric acid) can cause

osion and damage to the chassis.

4. Press the filler caps onto the battery.

Charging the Battery

IMPORTANT: Always keep the battery fully charged (1.260 specific gravity). This is especially important to prevent battery damage when the temperature is below 32°F (0°C).

1. Check the electrolyte level; refer to Checking

Electrolyte Level, page 33.

Cleaning

and Storage

1. Lower the loader arms and stop the engine.

Remove the key.

2. Remove dirt and grime from the external parts of

the entire traction unit, especially the engine. Clean dirt and chaff from the outside of the engine.

IMPORTANT: You can wash the traction unit with mild detergent and water. Do not pressure wash the traction unit. Avoid excessive use of water

, especially near the control panel, engine, hydraulic pumps, and motors.

3. Service the air cleaner; refer to Servicing the Air

Cleaner, page 27.

4. Grease the traction unit; refer to Greasing the

Traction Unit, page 29.
