!DANGER!….!WARNING!….!CAUTION!.

The meaning of these safety alerts is as follows:

Attention! Become Alert! Your Safety is Involved.

The message that appears under a Safety Alert

Symbol explains the hazard and can be either writ-

ten or pictorially presented.

! DANGER !

This symbol is used to alert service personnel of an

imminently hazardous situation that will result in seri-

ous injury or death.

! WARNING !

This symbol is used to alert service personnel of a

potentially hazardous situation that could result in

serious injury or death.

! CAUTION !

This symbol is used to alert service personnel of an

unsafe practice that could result in injury.

Information messages are provided in this document

and on the machine. These messages are identified

by the labels NOTICE….Note.

NOTICE

This label is used to alert service personnel to the possibil-

ity of damaging the equipment.

Note: This label is used to provide important additional

information, comments, explanations or amplification of

the accompanying subject matter.

The person servicing the Rubber Track Loader may

be unfamiliar with many of the systems on the ma-

chine. This makes it important to use caution when

performing service work. Knowledge of the system

and/or components is important before the removal

or disassembly of any component.

It is not possible to anticipate every circum-

stance that might involve a potential hazard. The

safety messages in this document and on the

product are, therefore, not all-inclusive. If you

use a tool, procedure, work method or operating

technique that is not specifically recommended

by the manufacturer, you must satisfy yourself

that it is safe for you and for others. You should

also ensure that the product will not be damaged

or be made unsafe by the operation, lubrication,

maintenance or repair procedures that you

choose.

Improper operation, lubrication, maintenance or repair

of this product can be dangerous and could result in

injury or death.

Do not operate or perform any lubrication, mainte-

nance or repair on this product until you have read

and understood the operation, lubrication, mainte-

nance and repair information.

Following is a list of basic precautions that should

always be observed.

Safety Signs

Read and understand all "Safety" signs on the prod-

uct before operating, lubricating or repairing this

product. Replace any damaged, illegible or missing

safety plates, signs or decals.

Rubber Track Loader

1. Product Safety

1-2

Protective Equipment

Always wear a hard hat, protective glasses, protec-

tive shoes and other protective equipment as re-

quired by job conditions when working around this

product. In particular, wear protective glasses when

pounding on any part of the product or its attach-

ment with a hammer or sledge. Use welders gloves,

hood/goggles, apron and other protective clothing

appropriate to the welding job being performed. Do

not wear loose clothing or jewelry that can catch on

parts of the product.

Mounting and Dismounting

Use steps and handholds when mounting or dis-

mounting a machine. Clean any mud or debris from

steps or work platforms before using them. Always

face the machine when using steps and handholds.

When it is not possible to use the designed access

system, provide ladders, scaffolds, or work platforms

to perform safe repair operations.

Lifting

Use a hoist when lifting components that weigh 23

kg (50 Ib) or more, to avoid back injury. Make sure

all chains, hooks, slings, etc., are in good condition

and are of the correct capacity. Be sure hooks are

positioned correctly and equipped with a spring

latch. Lifting eyes are not to be side loaded during a

lifting operation.

Hot Fluids and Parts

To avoid burns, be alert for hot parts on machines

that have just been stopped and hot fluids in lines,

tubes and compartments.

Be careful when removing fill caps, breathers and

plugs on the machine. Hold a rag over the cap or

plug to prevent being sprayed or splashed by liquids

under pressure. The danger is even greater if the

machine has just been stopped because fluids can

be hot.

Corrosion Inhibitor

Corrosion inhibitor contains alkali. Avoid contact with

eyes. Avoid prolonged or repeated contact with skin.

Do not take internally. In case of contact, wash skin

immediately with soap and water. For eyes, flush

with large amounts of water for at least 15 minutes.

Call Physician. Keep out of reach of children.

Batteries

Do not smoke when inspecting the battery electro-

lyte level. Never disconnect any charging unit circuit

or battery circuit cable from the battery when the

charging unit is operating. A spark can cause an

explosion from the flammable vapor mixture of hy-

drogen and oxygen that is released from the electro-

lyte through the battery outlets. Do not let electrolyte

solution make contact with skin or eyes. Electrolyte

solution is an acid. In case of contact, immediately

wash skin with soap and water. For eyes, flush with

large amounts of water for at least 15 minutes. Call

Physician. Keep out of reach of children.

Pressurized Items

1. Always use a board or a piece of cardboard

when you check for a leak. Leaking fluid under

pressure can penetrate body tissue. Fluid pene-

tration can cause serious injury and possible

death. A pinhole leak can cause severe injury. If

fluid is injected into your skin, get treatment im-

mediately. Seek treatment from a doctor that is

familiar with this type of injury.

2. Relieve all pressure in air, oil or water systems

before disconnecting or removing any lines, fit-

tings or related items. Always make sure all

raised components are blocked correctly and be

alert for possible pressure when disconnecting

any device from a system that utilizes pressure.

3. Lower the bucket, blade, or other attachment to

the ground before performing any work on the

machine. If this cannot be done, make sure the

bucket, blade, or other attachment is blocked

correctly to prevent it from dropping unexpect-

edly.

4. Loose or damaged fuel, lubricant and hydraulic

lines, tubes and hoses can cause fires. Do not

bend or strike high-pressure lines or install ones

that have been bent or damaged. Check lines,

tubes and hoses carefully. Do not use your bare

hand to check for leaks.

5. Pressurized air or water can cause personal in-

jury. When pressurized air or water is used for

cleaning, wear a protective face shield, protec-

tive clothing, and protective shoes. The maxi-

mum air pressure for cleaning purposes must be

below 205 kPa (30 psi). When using a pressure

washer, keep in mind that nozzle pressures are

very high, generally pressures are well above

13790 kPa (2000 psi). Follow all recommended

practices provided by the pressure washer

manufacturer.

Repair

! WARNING !

Accidental machine starting can cause injury or death

to personnel working on the machine.

To avoid accidental machine starting, disconnect the

battery cables from the battery and tape the battery

clamps and remove the key.

Place a “Do Not Operate” tag prominently on the ma-

chine to inform personnel that the machine is being

worked on.

1. Disconnect battery and discharge any capacitor

before starting to work on the product. Attach a

Do Not Operate tag in the Operator's Compart-

ment.

2. If possible, make all repairs with the machine

parked on a level, hard surface. Block the ma-

chine to prevent it from rolling while working on

or under the machine.

3. Do not work on any machine that is supported

only by lift jacks or a hoist. Always use blocks or

jack stands to support the machine before per-

forming any service or disassembly.

4. Make sure the work area around the product is

made safe and be aware of hazardous condi-

tions that may exist. If an engine is started inside

an enclosure, make sure that the engine’s ex-

haust is properly vented.

5. Be sure all protective devices including guards

and shields are properly installed and function-

ing correctly before starting a repair. If a guard

or shield must be removed to perform the repair

work, use extra caution.

6. Always use tools that are in good condition and

be sure you understand how to use them before

performing any service work.

7. Replace all fasteners with the same part num-

ber. Do not use a lesser quality fastener if re-

placements are necessary.

8. Be prepared to stop an engine if it has been re-

cently overhauled or the fuel system has been

recently worked on. If the engine has not been

assembled correctly, or if the fuel settings are

not correct, the engine can possibly overspeed

and cause bodily injury, death or property dam-

age. Be prepared to shut off the fuel and air

supply to the engine in order to stop the engine.

9. Be careful when removing cover plates. Gradu-

ally back off the last two bolts or nuts located at

opposite ends of the cover or device. Then, pry

the cover loose to relieve any spring or other

pressure before removing the last two nuts or

bolts completely.

10. Repairs requiring welding should be performed

only with the benefit of the appropriate reference

information and by personnel adequately trained

and knowledgeable in welding procedures. De-

termine the type of metal being welded and se-

lect the correct welding procedures and

electrodes, rods or wire to provide a weld metal

equivalent at least to that of the parent weld.

11. Do not damage wiring during removal opera-

tions. Reinstall the wiring so it is not damaged

during installation or operation by contacting

sharp corners or by rubbing against some object

or hot surface.

12. Always use lift arm supports to keep lift arms

raised. Keep the attachment tilted down and as-

sure that all hydraulic pressure has been re-

lieved for maintenance or repair work that

requires the lift arms to be in the raised position.

13. Tighten connections to the correct torque. Make

sure that all heat shields, clamps and guards are

installed correctly to avoid excessive heat, vibra-

tion or rubbing against other parts during opera-

tion. Shields that protect against oil spray onto

hot exhaust components in event of a line, tube

or seal failure must be installed correctly.

14. Do not operate a machine if any rotating part is

damaged or contacts another part during opera-

tion. Any high-speed rotating component that

has been damaged or altered should be

checked for balance before reusing. Make sure

all protective devices, including guards and

shields, are properly installed and functioning

correctly before starting the engine or operating

the machine.

Attachments

Only use attachments that are recommended by the

manufacturer of the machine.

Make sure that all necessary guarding is in place on

the host machine and on the attachment.

Wear protective glasses and protective equipment

as required by conditions or as recommended in the

attachment’s operation manual.

Rubber Track Loader

1. Product Safety

1-4

Ensure that all personnel are far enough away from

the work area so they will not be struck by flying ob-

jects.

Stay clear of the cutting edges, pinching surfaces or

crushing surfaces of the attachment while perform-

ing any attachment maintenance, testing or adjust-

ments.

Asbestos Information

Equipment and replacement parts shipped from the

manufacturer are asbestos free. When replacement

parts are required, use only genuine manufacturer’s

replacement parts

Use caution when handling replacement parts from

another supplier if these parts contain asbestos.

Avoid inhaling dust that might be generated when

handling these components or when handling as-

bestos debris. Inhaling this dust can be hazardous to

your health.

The components that may contain asbestos fibers

are lining material, and some gaskets. The asbestos

that is used in these components is usually encased

in a resin or sealed in some way. Normal handling is

not hazardous unless airborne dust containing as-

bestos is generated.

If dust that may contain asbestos is present, there

are several guidelines that should be followed.

1. Never use compressed air for cleaning. Avoid

brushing or grinding materials that contain as-

bestos. Use a wet method to clean up asbestos

debris. A vacuum that is equipped with the high-

efficiency particulate air filter (HEPA filter) can

also be used.

2. Use exhaust ventilation on permanent machin-

ing jobs.

3. Wear an approved respirator if there is no other

way to control the dust.

4. Comply with applicable rules and regulations for

the work place. In the USA, use Occupational

Safety and Health Administration requirements.

These OSHA requirements can be found in 29

CFR 1910.1001.

5. Obey environmental regulations for disposal of

asbestos.

6. Stay away from areas that might have asbestos

particles in the air.

! WARNING !

When replacement parts are required for this product,

use only genuine manufacturer’s replacement parts or

parts with equivalent specifications including, but not

limited to physical dimensions, type, strength and

material.

Failure to heed this warning can lead to premature

failures, product damage, personal injury or death.

Machine Labels and Decals

Labels and decals placed on the machine provide

safety information and operating instructions. Make

sure you know the location of these labels and un-

derstand their significance.

Product ID Number
