SAFE OPERATION
SAFE OPERATION
You can avoid most accidents with the loader
equipment by following simple safety instructions.
Safety precautions for the loader, if they are followed at
all times, will help you operate your loader safely.
• Kubota recommends the use of Kubota
attachments on Kubota loaders. NonKubota attachments, if used, must comply
with ISO 24410, first edition 2005-04-15.
• 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.
PRECAUTIONS BEFORE
OPERATING THE LOADER
• Read and understand all instructions and
precautions in both the tractor and the loader
operator's manuals before using the loader.
Lack of knowledge can lead to accidents.
• 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.
• For your safety, Kubota strongly recommends using
a ROPS (rollover protective structure) with a seat
belt 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.
• Visually check for hydraulic leaks and broken,
missing, or malfunctioning parts.
Perform necessary repairs before operating the
loader.
• Replace damaged or illegible safety labels. See
SAFETY LABELS on page 6 for required labels.
• When the front loader is mounted on the tractor,
enter and exit the operator's seat only from left side
of the tractor.
• Engage the loader control valve lock to prevent
accidental actuation when the implement is not in
use or during transport. Do not utilize the loader
control valve lock for maintenance or repair of the
machine.
• Assemble, remove, and reinstall the loader only as
directed in this manual. Otherwise, serious personal
injury or death may result.
• Follow the precautions below when attaching
attachments.
– [2-lever quick coupler]
• Make sure that both handles of the boom
LH and RH contact the ear plates at the
points (A) and are all the way down.
• Make sure that both lock pins of the boom
LH and RH protrude through the pin slots.

– [Euro quick coupler]
• Make sure that the handle contacts the

• Make sure that both lock pins of LH and RH
protrude through both pin holes.
• Any attachment used with Euro quick
coupler must comply with ISO 23206
standard, published 2005.
• Use of a non-Kubota attachment that does
not comply with ISO 23206 standard or the
improper positioning of handle or nonprotrusion of pin(s) may result in
detachment
of
the
attachment
or
deformation, causing loss of performance,
personal injury, or death.

PRECAUTIONS FOR
OPERATING THE LOADER
• Operate the loader only when properly seated at
the controls. Do not operate the loader from the
ground.
• Move and turn the tractor at low speeds.
• Never allow anyone to get under the bucket of the
loader or reach through the boom when the bucket
is raised.
• Keep children, others, and livestock away when
operating the loader and the tractor.
• Do not walk or work under a raised bucket of the
loader or attachment unless it is securely blocked
and held in position.
• For the stability of the tractor and operator's safety,
add rear ballast to the 3-point hitch and / or to the
rear wheels when using the loader.
• To increase stability of the tractor, adjust the rear
wheels to the widest setting that is suitable for your
application.
• Exercise extra caution when operating the loader
with a raised bucket or attachment.
• Do not lift or carry any person on the loader, in the
bucket, or other attachment.
• Avoid loose fill, rocks, and holes. Loose fill, rocks,
and holes can be dangerous for operation or
movement of the loader.
• Avoid overhead wires and obstacles when the
loader is raised. Contacting the electric lines can
cause electrocution.
• Gradually stop the loader boom when lowering or
lifting.
• Use caution when handling loose or shiftable loads.
• When using the loaders for handling large, heavy,
or shiftable objects, using proper handling
attachments with them is recommended.
• Handling large, heavy objects can be extremely
dangerous due to the following reasons:
4
•
•
•
•
•
•
– Danger of rolling the tractor over
– Danger of upending the tractor
– Danger of the object rolling or sliding down the
boom of the loader onto the operator
If you must handle the large, heavy objects, protect
yourself by the following preventive measures:
– Never lift the load higher than necessary to
clear the ground.
– Add the rear ballast to the tractor to
compensate for the load or use the rear
implement.
– Never lift large objects with the equipment that
may permit the large objects to roll back onto
the operator.
– Move slowly and carefully, avoiding rough
terrain.
Never lift or pull a load from any point on the loader
or any attachments with a chain, rope, or cable.
Otherwise, rollover or serious damage to the loader
may occur.
Be extra careful when operating the tractor on a
slope. Always operate the tractor up and down, and
never across the slope.
Do not operate the tractor on steep slopes or
unstable surfaces.
When operating another implement on a hillside, be
sure to remove the loader to reduce the risk of
rollover.
Carry the boom of the loader at a low position
during transport. Ensure that you are able to see
over the bucket.
Allow for the length of the loader when turning the
tractor.
PRECAUTIONS AFTER
OPERATING THE LOADER
• When loader work is complete and parking or
storing, follow the following procedures before
leaving the operator's seat of the tractor.
1. Choose flat, hard ground.
2. Lower the boom of the loader to the ground.
3. Stop the engine.
4. Set the brakes.
5. Remove the key from the ignition.
• Make sure that the removed loader is on stands
and on a hard, level surface.
• Before disconnecting the hydraulic lines, relieve all
hydraulic pressure by moving the controls.
• Do not remove the loader from the tractor without
an approved bucket attached.
LA535
SAFE OPERATION
PRECAUTIONS FOR
SERVICING THE LOADER
• Always wear safety goggles when servicing or
repairing the machine.
• Do not modify the loader. Unauthorized modification
may affect the function of the loader, which may
result in personal injury.
• 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. Hydraulically supported devices
can settle, suddenly leak down, or be accidentally
lowered.
LA535
• Escaping hydraulic oil under pressure can produce
sufficient force to penetrate the skin, causing
serious personal injury. Do not use hands to search
for suspected leaks. Use a piece of cardboard or
wood to search for suspected leaks. If injured by
escaping
fluid,
obtain
medical
treatment
immediately.
• Do not tamper with the setting of the relief valve.
The relief valve is pre-set at the factory. Changing
the setting of the relief valve can cause overloading
of the loader and tractor which may result in serious
personal injury.
• When servicing or replacing the pins in cylinder
ends, bucket, and so on, always use a brass drift
and hammer. Otherwise injury from flying metal
fragments could result.

1. Care for safety labels
• Keep the safety labels clean and free from
obstructing material.
• Clean the safety labels with soap and water, and
dry the safety labels with a soft cloth.
• Do not spray high-pressure water directly on the
safety labels, otherwise the safety labels may peel
off.
• Replace damaged or missing safety labels with new
safety labels from your local Kubota Dealer.
• If a component with safety label(s) attached is
replaced with new component, make sure that new
safety label(s) is (are) attached in the same
location(s) as the replaced component.
• Attach new safety labels by applying on a clean, dry
surface and pressing any bubbles to outside edge.

Refer to the tractor operator's manual for optional tires.
LA535
To avoid personal injury or death:
• Keep engine speed at low idle during the test
operation of the loader.
• Escaping hydraulic oil under pressure can
produce sufficient force to penetrate skin,
causing serious personal injury.
Before disconnecting lines, be sure to relieve all
pressure by moving the controls.
• Before applying pressure to the loader system,
be sure that all connections are tight and that
lines, tubes, and hoses are not damaged.
• Hydraulic fluid escaping from a very small hole
can be almost invisible. Use a piece of
cardboard or wood to search for suspected
leaks. Do not use hands to search for
suspected leaks.
• If injured by escaping fluid, see a doctor at
once. Serious infection or allergic reaction may
19

attachments, keep the following point in mind.
• Control lever and hydraulic hose connections.
• Loader/remote control valve lever.
NOTE :
• When the control lever is at each corner
position marked by asterisk [*], cylinder of the
boom and bucket work at the same time.
However, the lower left position (raise and roll
back) is not recommended for scooping
because of insufficient lift force.
IMPORTANT :
• If the boom or bucket of the loader does not
work in the directions indicated on the label,
follow the following procedure.
1. Lower the bucket to the ground.
2. Stop the engine.
3. Relieve all hydraulic pressure.
4. Recheck

WARNING
To reduce the possibility of roll over:
• It is not recommended that the loader be
attached when operating another implement on
a hillside.
IMPORTANT :
• Before operating the loader in rough terrain,
remove the mower to avoid damage to the
mower (Only when the tractor is equipped with
the mower).
The operator should adjust the engine speed of tractor
when operating the loader depending on the operator's
level of experience and the type of work you are doing.
Excessive speeds are dangerous and may cause
spillage of the bucket and unnecessary strain on the
tractor and the loader.
When operating in temperatures below -1 ℃ (30 ℉), run
the tractor engine below 1200 rpm until the oil
temperature exceeds -1 ℃ (30 ℉).

2. Precautions for lifting the load
WARNING
To avoid personal injury or death:
• Do not lift the loads in the bucket in excess of
the loader capacity.
• Before raising the bucket to full height, make
sure that the tractor is on level ground. If the
tractor is not on level ground, the tractor may
tip over, even if it is not moving.
When lifting the load, keep the bucket positioned to
avoid spillage.
2. Ease the loader control lever toward you and then
left to rollback and lift the bucket.
3. Precautions for carrying the load
WARNING
To avoid personal injury or death:
• Be extra careful when working on inclines.
• When operating on a slope, always operate the
tractor up and down the slope, never across the
slope.
NOTE :
• Do not be concerned if the bucket is not
completely filled during each pass.
Maximum productivity is determined by the
amount of material loaded in a given period
of time. Two or more tries to fill the bucket
on each pass may take more time.
(A) Incorrect
(B) Correct
• Position the bucket just below the level of the
tractor hood for maximum stability and visibility,
whether the bucket is loaded or empty.
LA535
23
OPERATING THE LOADER
TECHNIQUES FOR OPERATING THE LOADER AND THE TRACTOR
• Use extreme care when operating the loader on a
slope. Keep the bucket as low as possible. Keeping
the bucket low keeps the bucket and the tractor
center of gravity low and will provide maximum
stability of the tractor.
• When transporting a load, keep the bucket as low
as possible to avoid tipping in case a wheel drops
in a rut.
Lowering the bucket
1. After dumping the bucket, back away from the
vehicle while lowering and rolling back the bucket.
5. Precautions for operating the
loader with float control
• During operation of the loader on hard surface,
keep the bucket level and put the lift control in the
float position to permit the bucket to float on the
working surface. If hydraulic down pressure is
exerted on the bucket, the bucket will wear faster
than normal.
(A) Incorrect
(B) Correct
4. Dumping and lowering the bucket
Dumping the bucket
1. Lift the bucket just high enough to clear the side of
the vehicle.
2. Move the tractor in as close to the side of the
vehicle as possible.
3. Then dump the bucket.
24
(A) Float
• The float position will also avoid mixing of surface
material with stockpile material. The float position
will reduce the chance of surface gouging while
removing snow or other material, or when working
with a blade.

(B) Surface material
6. Loading from a bank
OPERATING THE LOADER
• If the pile sides are too high and liable to cause
cave-in, use the loader to break down the sides
until a slot can be cut over the top.
WARNING
To avoid personal injury or death:
• Be extra careful when working on inclines.
• When operating on a slope, always operate the
tractor up and down the slope, never across the
slope.
• Choose a forward gear that provides a safe ground
speed and power for loading.
• Another method for large dirt piles is to build a ramp
to approach the pile.
NOTE :
– Loader lift and break-away capacity
diminish as loading height is increased.
• Side cutting is a good technique for cutting down a
big pile. Wheel width should not exceed the bucket
width for the side cutting procedure.
LA535
• It is important to keep the bucket level when
approaching a bank or pile. This will help avoid
gouging the work area.
25
OPERATING THE LOADER
TECHNIQUES FOR OPERATING THE LOADER AND THE TRACTOR
3. Make additional passes until the desired depth is
reached.
During each pass, use only the bucket control while
at working depth. Using only the bucket control will
allow you to concentrate on controlling the bucket
angle to maintain a precise cut.
7. Peeling and scraping the ground
1. Produce a short cut and break-out cleanly.
a. Use a slight bucket down angle.
b. Travel forward.
c. Hold the lift control forward to start the cut.
8. Loading low trucks or spreaders
from a pile
• For faster loading, minimize the angle of turn and
length of operation between pile and spreader.
2. With the bucket level, start a cut at the following
notch.
Notch
Approximately 2 in. deep
• Back grade occasionally with a loaded bucket to
keep the work surface free of ruts and holes. Also,
hold the lift control forward.
The full weight of the bucket is scraping the ground.
Use the heel of the bucket to scrape the ground.
Hold the depth by feathering the bucket control to
adjust the cutting edge up or down. When the front
tires enter the notch, adjust the boom cylinder to
maintain proper depth.
26
LA535
TECHNIQUES FOR OPERATING THE LOADER AND THE TRACTOR
OPERATING THE LOADER
• Leave dirt in the bucket because dumping on each
pass wastes time.
9. Backfilling
• Approach the pile with the bucket flat.
Poor operating methods will move less dirt and
make it more difficult to hold a level grade.
• Operate at right angles to the ditch. Take as big a
bite of the soil pile as the tractor can handle.
(A) Ditch
(B) Soil pile
• Leave dirt which drifts over the side of the bucket
for final cleanup.
(A) Correct
(B) Incorrect
IMPORTANT :
– Do not use the bucket in the dumped
position for bulldozing the pile. As shown in
the preceding method, approaching the pile
with the bucket in the dumped position will
impose severe shock loads on the dumplinkage, the bucket cylinders, and the
tractor.

DAILY CHECKING THE LOADER
To avoid personal injury or death:
• Escaping hydraulic fluid under pressure can
produce sufficient force to penetrate skin,
causing serious personal injury.
Before disconnecting lines, be sure to
relieve all pressure.
• Before applying pressure to the loader
system, be sure that all connections are
tight and that lines, tubes, and hoses are not
damaged.
• Fluid escaping from a pin hole can be
almost invisible. Use a piece of cardboard or
wood to search for suspected leaks. Do not
use hands to search for suspected leaks.
• If you are injured by escaping fluid, see a
doctor at once. Serious infection or allergic
reaction will develop if proper medical
treatment is not administered immediately.
WARNING
To avoid personal injury or death:
• When removing the engine side covers, be
careful not to touch hot loader cylinders. Allow
all surfaces to cool before performing
maintenance.
• Before servicing the loader or the tractor, be
sure to place the boom of the loader in contact
with the ground. When raising the boom of the
loader during service or maintenance, support
the boom as shown in the figure.
