Safe Operating Practices

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

Warning

Engine exhaust contains carbon monoxide, an odorless, deadly poison that can kill you.

Do not run the engine indoors or in an enclosed area.

• Never refuel or drain the machine indoors.

• Check that the operator’s presence controls, safety

switches, and shields are attached and functioning properly. Do not operate unless they are functioning properly.

Operation

• Never run an engine in an enclosed area.

• Only operate in good light, keeping away from holes

and hidden hazards.

• Be sure all drives are in neutral and parking brake is

engaged before starting the engine. Only start the engine from the operator’s position.

• Slow down and use extra care on hillsides. Be sure to

travel in the recommended direction on hillsides. Turf conditions can affect the machine’s stability.

• Do not touch parts which may be hot from operation.

Allow them to cool before attempting to maintain,

adjust, or service.

• Slow down and use caution when making turns and

when changing directions on slopes.

• Never operate with the guards not securely in place.

Be sure all interlocks are attached, adjusted properly, and functioning property.

• Do not change the engine governor setting or

overspeed the engine.

• Stop on level ground, lower implements, disengage the

auxiliary hydraulics, engage parking brake, shut off the engine before leaving the operator’s position for any reason.

• Keep hands and feet away from moving attachments.

• Look behind and down before backing up to be sure of

a clear path.

• Never carry passengers and keep pets and bystanders

away.

• Slow down and use caution when making turns and

crossing roads and sidewalks.

• Do not operate the machine under the influence of

alcohol or drugs

• Use care when loading or unloading the machine into a

trailer or truck

• Use care when approaching blind corners, shrubs,

trees, or other objects that may obscure vision.

• Read all attachment manuals.

• Ensure that the area is clear of other people before

operating the traction unit. Stop the traction unit if anyone enters the area.

• 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.

• 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 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.

• 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.

• 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 controls; use a steady motion.

• Watch for traffic when operating near or crossing

roadways.

• 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 traction

unit loses 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.

• 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.

• Never remove the gas cap or add fuel when the

engine is running. Allow the engine to cool before refueling. Do not smoke.

Maintenance and Storage

• Disengage the auxiliary hydraulics, lower the

attachment, set the parking brake, stop the engine, and remove the key. Wait for all movement to stop before adjusting, cleaning, or repairing.

• Clean debris from attachments, drives, mufflers, and

engine to help prevent fires. Clean up oil or fuel spillage.

• Let the engine cool before storing and do not store

near flame.

• Do not store fuel near flames or drain indoors.

• Park the machine on level ground. Never allow

untrained personnel to service the machine.

• Use jack stands to support components when required.

• Carefully release pressure from components with

stored energy.

• Disconnect the battery or remove the spark plug wires

before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last.

• Keep hands and feet away from moving parts. If

possible, do not make adjustments with the engine running.

• Charge batteries in an open well ventilated area, away

from spark and flames. Unplug the charger before connecting or disconnecting it from the battery. Wear protective clothing and use insulated tools.

• 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 Toro 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; never use your hands. 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.

• Keep all parts in good working condition and all

hardware tightened. Replace all worn or damaged decals.

• 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.

• Secure the loader arm valve with the loader valve lock

anytime you need to stop the machine with the loader arms raised.

Attachments

Many attachments are available for use with the traction unit. These attachments allow you to to perform many different functions with the traction unit such as hauling materials, digging holes, grading, and more. Contact your Toro dealer for a list of all approved attachments and accessories.

Important Use only Toro-approved attachments.

Stability Data

The following tables list the maximum slope recommended for the traction unit in the positions listed in the tables. Slopes over the listed degree may cause the traction unit to become unstable. The data in the tables assume that the loader arms are fully lowered; raised arms may affect the stability.

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 stability ratings of the attachment. Example: If the attachment installed on a TX 420 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 following table for the TX 420 traction unit.
