-1SAFE OPERATION

SAFE OPERATION

Most loader equipment accidents can be avoided by following simple safety precautions.

These safety precautions, if followed at all times, will help you operate your loader safely.

1. Read and understand all instructions and precautions

found in both the tractor and the loader operator's

manuals before using the loader.

Lack of knowledge can lead to accidents.

2. It is the owner's responsibility to ensure that anyone

who will operate the loader reads this manual first and

becomes familiar with the safe operation of the loader.

3. For your safety, a ROPS with a seat belt is strongly

recommended by KUBOTA in almost all applications.

If your tractor has a foldable ROPS, fold it down only

when absolutely necessary and raise it up and lock it

again as soon as possible. Do not wear the seat belt

when a foldable ROPS is down or a fixed ROPS is

removed. If you have any questions, consult your local

KUBOTA dealer.

Always use the seat belt when the tractor is equipped

with a ROPS. Never use the seat belt when the tractor

is not equipped with a ROPS.

4. Visually check for hydraulic leaks and broken, missing,

or malfunctioning parts.

Make necessary repairs before operating.

5. Replace damaged or illegible safety labels. See

following pages for required labels.

6. When the front loader is mounted on the tractor, enter

and exit the operator's seat only from left side of the

tractor.

7. Engage the loader control valve lock to prevent

accidental actuation when the implement is not in use

or during transport. Do not utilize the valve lock for

machine maintenance or repair.

8. Assemble, remove and reinstall the loader only as

directed in this manual. Failure to do this could result

in serious personal injury or death.

9. Follow the precautions below when attaching

attachments.

A Make sure both handles (LH, RH) contact the ear

plates at the points (A) and are all the way down.

A Make sure both lock pins (LH, RH) protrude through

the pin slots.

A Kubota recommends the use of Kubota attachments

on Kubota loaders. Non-Kubota attachments, if used,

must comply with ISO 24410, first edition 2005-04-15.

A Use of a non-Kubota attachment that does not comply

with ISO 24410 or the improper positioning of

handle(s) or non-protrusion of pin(s) may result in

detachment of the attachment or deformation, causing

loss of performance, personal injury or death.

1. BEFORE OPERATING THE LOADER

(1) Handle

(2) Ear plate

(3) Pin slot

(4) Lock pin

(A) The handle contacts the ear

plate at the points.

SAFE OPERATION-2

1. Operate the loader only when properly seated at the

controls. Do not operate from the ground.

2. Move and turn the tractor at low speeds.

3. Never allow anyone to get under the loader bucket or

reach through the boom when the bucket is raised.

4. Keep children, others and livestock away when

operating loader and tractor.

5. Do not walk or work under a raised loader bucket or

attachment unless it is securely blocked and held in

position.

6. For tractor stability and operator safety, rear ballast

must be added to the 3-point hitch and to the rear

wheels when using loader.

7. To increase stability adjust the rear wheels to the

widest setting that is suitable for your application.

8. Exercise extra caution when operating the loader with

a raised bucket or attachment.

9. Do not lift or carry any person on the loader, in the

bucket, or other attachment.

10.Avoid loose fill, rocks and holes. They can be

dangerous for loader operation or movement.

11.Avoid overhead wires and obstacles when the loader

is raised. Contacting electric lines can cause

electrocution.

12.Gradually stop the loader boom when lowering or

lifting.

13.Use caution when handling loose or shiftable loads.

14.Using loaders for handling large, heavy, or shiftable

objects is not recommended without proper handling

attachments.

15.Handling large heavy objects can be extremely

dangerous due to :

A Danger of rolling the tractor over.

A Danger of upending the tractor.

A Danger of the object rolling or sliding down the

loader boom onto the operator.

16.If you must perform this sort of work (item 15), protect

yourself by :

A Never lift the load higher than necessary to clear

the ground.

A Add rear ballast to the tractor to compensate for the

load or use rear implement.

A Never lift large objects with equipment that may

permit them to roll back onto the operator.

A Move slowly and carefully, avoiding rough terrain.

17.Never lift or pull a load from any point on the loader

with a chain, rope, or cable. Doing so could cause a

rollover or serious damage to the loader.

18.Be extra careful when operating the tractor on a slope,

always operate up and down, never across the slope.

Do not operate on steep slopes or unstable surfaces.

19.When operating another implement on a hillside, be

sure to remove the loader to reduce the risk of rollover.

20.Carry loader boom at a low position during transport.

(You should be able to see over the bucket.)

21.Allow for the loader length when making turns.

1. When loader work is complete and parking or storing,

choose flat and hard ground. Lower the loader boom

to the ground, stop the engine, set the brakes and

remove the key before leaving the tractor seat.

2. Make sure the detached loader is on stands and on a

hard, level surface.

3. Before disconnecting hydraulic lines, relieve all

hydraulic pressure by moving the controls.

4. Do not remove the loader from the tractor without an

approved bucket attached.

1. Always wear safety goggles when servicing or

repairing the machine.

2. Do not modify the loader. Unauthorized modification

may affect the function of the loader, which may result

in personal injury.

3. Do not use the loader as a work platform or a jack to

support the tractor for servicing or maintenance.

Securely support the tractor or any machine elements

with stands or suitable blocking before working

underneath.

For your safety, do not work under any hydraulically

supported devices. They can settle or suddenly leak

down or be accidentally lowered.

4. Escaping hydraulic oil under pressure can have

sufficient force to penetrate the skin, causing serious

personal injury. Do not use hands to search for

suspected leaks. If injured by escaping fluid, obtain

medical treatment immediately.

5. Do not tamper with the relief valve setting. The relief

valve is pre-set at the factory. Changing the setting

can cause overloading of the loader and tractor which

may result in serious personal injury.

6. When servicing or replacing pins in cylinder ends,

bucket, etc., always use a brass drift and hammer.

Failure to do so could result in injury from flying metal

fragments.

CARE OF DANGER,WARNING AND CAUTION LABELS

1. Keep danger, warning and caution labels clean and free from obstructing material.

2. Clean danger, warning and caution labels with soap and water, dry with a soft cloth.

3. Replace damaged or missing danger, warning and caution labels with new labels from your local KUBOTA dealer.

4. If a component with danger, warning and caution label (s) affixed is replaced with new part, make sure new label (s) is

(are) attached in the same location (s) as the replaced component.

5. Mount new danger, warning and caution labels by applying on a clean dry surface and pressing any bubbles to outside

edge.

TRANSMISSION FLUID

Check the tractor transmission fluid level. Add fluid if

necessary. Refer to the tractor operator's manual for

instructions and proper fluid. Repeat this check after

purging air from the system. At that time, it will be

necessary to add transmission fluid.

A To check the tractor transmission fluid level, lower the

PRE-OPERATION CHECK8

REAR BALLAST

To avoid personal injury:

A For tractor stability and operator's safety, rear

ballast should be added to the rear of the

tractor in the form of 3-point counter weight

and rear wheel ballast. The amount of rear

ballast will depend on the application.

BLiquid ballast in rear tires

Water and calcium chloride solution provides a safe and

economical ballast. Used properly, it will not damage tires,

tubes or rims. The addition of calcium chloride is

recommended to prevent the water from freezing. Use of

this method of weighting the wheels has full approval of

the tire manufacturers. See your tire dealer for this

service.

Liquid weight per tire (75 Percent filled)

A Do not fill tires with water or solution more than 75% of

full capacity (to the valve stem level at 12 o'clock

position).

A When mounting a heavy rear implement, liquid in the

tires may not be required.

A Do not add liquid ballast or any other weights to the

front tires.

Ensure that the tractor tires are properly inflated.
