-1SAFE OPERATION
SAFE OPERATION
Careful operation is your best insurance against an
accident.
Read and understand this section carefully before
operating the Wheel Loader.
All operators, no matter how much experience they may
have had, should read this and other related manuals
before operating the machine or any attachment. It is the
owner's obligation to instruct all operators in safe
operation.
1. BEFORE OPERATING THE WHEEL
LOADER
1. Know your equipment and its limitations. Read this
entire manual before attempting to start and operate
the machine.
2. If using an attachment on the machine, read the
attachment operator's manual to ensure safe
operating procedures.
3. Pay special attention to the danger and warning labels
on the machine and the attachments.
4. For your safety, ROPS(Roll-Over Protective
Structure)/FOPS(Falling-Object Protective Structure)
and a seat belt have been installed by KUBOTA.
Always use the seat belt when the machine is
equipped with canopy or cab.
ROPS/FOPS is required on Wheel Loaders,
Bulldozers, Truck Type Loaders, Graders and
Scrapers by OSHA and SAE regulations.
5. Never attempt to modify structural members of ROPS
by welding, drilling, bending, grinding or cutting, as this
may weaken the structure. If any component is
damaged, replace it. Do not attempt repairs. If ROPS
is loosened or removed for any reason, make certain
all parts are reinstalled correctly.
6. Do not install any attachments, including water and
calcium chloride that is added into the tires, that
exceed the specified maximum weight shown under
"MAXIMUM GROSS MACHINE WEIGHT" space on
the ROPS label.
7. Do not start or operate an unsafe machine. Before
working the machine, be sure that any unsafe
condition has been satisfactorily remedied. Check
brakes, steering and attachment controls before
moving. Consult a qualified technician if any
malfunctioning part of the system is observed. Be sure
all safety appliances are in the right place and in good
operating condition.
8. Wear and use safety gear such as non-slip safety
shoes or boots, safety glasses and safety hardhats.
Do not operate or work around the machine, when
wearing loose, bulky clothing.
9. Never operate the machine or any equipment while
under the influence of alcohol or other drugs, or while
fatigued.
10.Before allowing other people to use your machine,
give instruction to the operator on safe and correct use
of the machine and make sure the operator reads and
understands the Operator’s Manual for the machine.
11.Inspect your seat belt daily for signs of fraying, wear or
other weakness that could endanger your safety.
12.Do not use the loader bucket or an attachment to lift or
carry a person.

SAFE OPERATION-2
13.Do not use the bucket or any other parts of the
attachments to pull anything.
14.Carry out the following procedure in order to change
the attachment.
APosition the machine and attachment on level
ground.
AMake sure no persons are in the immediate vicinity
of the machine.
AWhen actuating the machine to change the front
attachment:
AStop the engine. (For machines with mechanical
quick coupler)
AActuate the parking brake switch.
ALower the bucket and attachment to the ground.
ARelease the hydraulic pressure in the hydraulic
system by operating the appropriate control levers.
(For machines with mechanical quick coupler)
ALock all control levers in neutral.
AAfter changing the front attachment, make sure the
installed attachment is securely attached to the
quick coupler.
15.To mount a fire extinguisher, use the space above the
fender on the side of the operator's seat.
16.Carry out the following procedure in order to lift the
machine.
AAttach the steering frame lock.
AUse the locations indicated by marks in the
diagram to lift the machine.
(1) Snap pin
(2) Steering frame lock (steering frame in locked position)

-3SAFE OPERATION
APass a nylon sling or chain through the lugs and lift
as shown in the diagram.
AUse only a nylon sling or chain that is capable of
holding the weight of the machine.
2. ENSURE THE DURABILITY OF THE
AXLE SUSPENSION
Improper handling of the machine damages the axle
suspension! To protect the axle suspension from
excessive wear, observe the following instructions.
AOnly use KUBOTA-approved tire sizes.
AObserve the tire pressure table. (See "Tire pressure"
in "TIRES" in "PERIODIC SERVICE" section.)
ACheck tire pressure before commencing day-to-day
operations.
ADo not use any liquids in the tires.
AReplace excessively worn tires with new tires before
commencing operations.
AOnly use identical wheels and tires with the same
degree of wear on the same axle.
ANever exceed the specified max. load capacity.
AOnly use KUBOTA-approved buckets, palette forks
and fork arms.
AWith more frequent loads at the thresholds, the
durability of the axle suspension must be ensured
through additional nuts (1) and bolts (2) on the front
and rear axle. Please contact your KUBOTA dealer.
(1) Lugs (Both sides)
(1) Nut
(2) Bolt

SAFE OPERATION-4
3. OPERATING THE MACHINE
1. Get on and off safely when entering or leaving the
operator’s cab. Face the machine. Always maintain a
three point contact with the steps and handrails. Do
not use control levers as handles.
Do not jump on or off the machine. Never try to get on
or off a moving machine.
2. Do not start engine or operate levers from anywhere
other than the seat.
3. Before starting the engine, fasten the seat belt, make
sure that the direction switch is set in the neutral
position, the parking brake switch is actuated and the
bucket is lowered to the ground.
4. Do not start engine by shorting across starter
terminals.
5. Watch where you are going at all times. Watch for and
avoid obstacles.
6. Never permit passengers on the machine. Keep
bystanders away from the machine during operation.
7. When working around other machines, let the other
operators know what you are doing at all times.
8. Never allow anyone to get under or near the bucket or
attachment when it is raised.
9. When raising the bucket or attachment, take extra
caution to prevent it from touching overhead wires or
other obstacles. Contact with wires may cause fatal
injuries.
10.Keep awayfrom the mufflerwhile the engineis running
and immediately after it has stopped.
11.Hazardous operation such as on dangerous terrain,
beyond the load capacity or contrary to the intended
use of the machine must be avoided as it may cause
the machine to tip over.
12.Do not drive the machine close to edges of ditches or
banks which may collapse under the weight of the
machine, especially when the ground is loose or wet.
13.Slow down for turns, uneven terrain and slopes to
avoid tipping over.
14.When transporting a load, keep the loader bucket as
low as possible to avoid tipping over. Be extremely
careful when working on inclines.
15.Operation on slopes can be dangerous. Rain, snow,
gravel soft ground, etc. will change the ground
conditions. Do not operate the machine in
questionable ground conditions. If operating on a
slope or ramp, always slow down, travel straight up
and down the incline and not across. Keep the bucket
as low as possible. If you do not follow these
instructions, the machine can go out of control and tip
over.
16.Avoid turning on a slope.
17.Never perform digging or shoveling with the machine
in the articulated condition, or the machine may tip
over.
18.Never dig or shovel at high speed. Such operation can
cause the machine to lose stability and its rear wheels
to lift off the ground, which may lead to serious
personal injury or fatal accidents.
19.Do not go up or down a 30 or steeper hill. Otherwise,
the machine may skid sideways or turn on its side.
If the ground is not level or is soft, limit the slope below
15 .
20.To avoid tipping over, do not operate the machine on
any site where the terrain cannot be ascertained, such
as ground covered with seeds or snow and check for
hidden projections, dips, road shoulders, etc.
beforehand, and take care not to approach them
during work.
21.Be sure to ease off the accelerator pedal at the end of
filling in trenches or areas at the edge of a steep slope
or pond bank or at the brow of a hill. When the external
load is reduced, the machine speed will automatically
increase, therefore reduce speed to avoid entering
ditches or tipping over.
22.To avoid the machine slipping or tipping over, do not
operate the machine on ungraded or soft terrain, such
as land fills. Grade and compact the site beforehand at
all times.
23.Do not run the engine indoors. Carbon monoxide gas
from exhaust is colorless, odorless and deadly.

CAvoiding crystalline silica (quartz) dust
To avoid serious injury or death from silica dust:
Avoid exposure to dust containing crystalline silica
particles.
This dust can cause serious injury to the lungs (silicosis).
Because crystalline silica is a basic component of sand
and granite, many activities at construction sites produce
dust containing crystalline silica.
Trenching, sawing and boring of material containing
crystalline silica can produce dust containing crystalline
silica.
If dust which contains crystalline silica is present, there
are guidelines which should be followed:
1. Be aware of the potential health effects of crystalline
silica and that smoking may add to the damage.
2. Be aware of and follow OSHA (or other local, State or
Federal) guidelines for exposure to airborne crystalline
silica.
3. Know the work operations where exposure to
crystalline silica may occur.
4. Participate in air monitoring or training programs
offered by the employer.
5. Be aware of and use optional equipment controls such
as water sprays, local exhaust ventilation, and
enclosed cabs with positive pressure air conditioning if
the machine has such equipment. Otherwise
respirators shall be worn.
6. Where respirators are required, wear a respirator
approved for protection against crystalline silica
containing dust. Do not alter the respirator in any way.
Workers who use tight-fitting respirators cannot have
beards/mustaches which interfere with the respirator
seal to the face.
7. If possible, change into disposable or washable work
clothes at the work site; shower and change into clean
clothing before leaving the work site.
8. Do not eat, drink, use tobacco products, or apply
cosmetics in areas where there is dust containing
crystalline silica.
9. Store food, drink and personal belongings away from
the work area.
10.Wash hands and face before eating, drinking,
smoking, or applying cosmetics after leaving the
exposure area.
4. TRAVELING
1. Before traveling on the public road, observe all local
and state traffic regulations. Use SMV emblem and
warning flashers as required.

13.If a tire has blown, the machine may slip or turn over.
In such cases do not brake or steer hard, brake slowly
to stop the machine and prevent tipping over.
CPrecautions at overheating of the engine
Take the following actions in the event the coolant
temperature increases too much. This condition is called
"Overheating".
1. Park the machine in a safe place and keep the engine
idling.
2. Do not stop the engine until after about 5 minutes of
idling.
3. Keep yourself well away from the machine for a further
10 minutes or while the steam blows out.
4. When there is no longer any danger of scalding, try to
find the cause of overheating according to the manual,
see "Troubleshooting" section and then start again the
engine.
5. AFTER OPERATION
1. When getting off the machine, always stop the engine,
lower the bucket and attachment to the ground,
release the hydraulic pressure in the hydraulic system
by operating the control levers (For details, refer to

13.Never remove the engine/hydraulic oil plug or the
radiator cap right after the engine has been stopped,
or oil or hot water may gush out. Wait for the water or
oil to cool, loosen the plug or cap just a little to release
pressure, and then check the level. This is especially
important for opening the radiator.
14.Escaping hydraulic fluid under pressure can cause
serious injury. Before applying pressure to the system,
be sure that all connections are tight and that lines,
pipes and hoses are not damaged. Fluid escaping
from a very small hole can be almost invisible. Do not
use your hands to search for suspected leaks, use a
piece of cardboard or wood. If injured by escaping
fluid, see a doctor at once. Serious infection or
reaction may result if proper medical treatment is not
administered immediately.
