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.

-1SAFE OPERATION

1. BEFORE OPERATING THE LOADER

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) Handle
(2) Ear plate
(3) Pin slot
(4) Lock pin

(A) The handle contacts the ear
plate at the points.

SAFE OPERATION-2

2. OPERATING THE LOADER

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.

3. AFTER OPERATING THE LOADER

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.

4. SERVICING THE LOADER

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.

DANGER,WARNING AND CAUTION LABELS

-3SAFE OPERATION

SAFE OPERATION-4

-5SAFE OPERATION

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.

SERVICING OF LOADER

Your dealer is interested in your new loader and has the
desire to help you get the most value from it. After reading
this manual thoroughly, you will find that you can do some
of the regular maintenance yourself.
However, when in need of parts or major service, be sure
to see your KUBOTA dealer.
For service, contact the KUBOTA dealership from which
you purchased your loader or your local KUBOTA dealer.
When in need of parts, be prepared to give your dealer the
loader serial number.
Locate the serial numbers now and record them in the
space provided.
