• Study control lever pattern A and pattern B. Then
choose the one which feels most familiar.
Familiarize yourself with the pattern selected by
operating the machine slowly and at low engine
speed.
• The tracks can be set to narrow width (750 mm) or
to standard width (990 mm).
(See TRACK WIDTH ADJUSTMENT AND DOZER
OPERATION on page 43.)
• Do not operate in narrow track width (750 mm), as
there is a risk of the machine tipping over.
• Always operate in standard track width (990 mm),
except to pass through narrow spaces on even
ground.
(A) 990 mm
(B) 750 mm
• Do not operate the machine while under the
influence of alcohol, medication, controlled
substances, or while fatigued.
• Check the surroundings carefully before using the
machine or when attachments are being attached.
– Pay attention to the overhead clearance with
electric wires.

– While using the machine, do not allow any
persons within the working range.
– Check local regulations and contact Before You
Dig Australia (http://byda.com.au).
• Do not allow other persons to use the machine
before having informed them on the exact operation
and work instructions, and make sure that they
have read and fully understood the operator's
manual.
• Do not wear baggy, torn, or oversized clothing
when working with the machine. Clothing can get
caught in rotating parts or control elements,
resulting in accidents or injuries. Wear adequate
safety clothing, such as a safety helmet, safety
shoes, eye protection, ear protection, working
gloves, and so on, as necessary and as prescribed
by law or other standards or regulations.
(1) Helmet
(2) Clothing fit for work
(3) Tight seams

(9) Baggy trousers
(10) Loose cuffs of the shirt
(11) Baggy shirt
(12) Sandals or open-toed shoes
• Do not allow passengers to ride on any part of the
machine at any time. The operator must remain in
the machine seat during operation.
• Check mechanical parts for wear, and make sure
that they are correctly adjusted. Replace worn or
damaged parts immediately. Check nuts and bolts
regularly to make sure that they are tightened to the
correct torque.
• Keep your machine clean. Heavy soiling, grease,
dust and grass can cause fires, accidents or
injuries.
• Use only Kubota's authorized attachments.
• Before starting the machine, be absolutely sure that
the machine has been filled with fuel, lubricated,
greased, and undergone all necessary
maintenance.
• Do not modify the machine, otherwise it could lead
to unforeseen safety problems.
2. ROPS
• For your safety, a roll-over protective structure
(ROPS) with a seat belt is installed.
• Always use the seat belt when the machine is
equipped with a ROPS as this combination will
reduce the risk of serious injury or death in case of
machine tip-over or instability.
• Do not modify any structural members of the 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 the ROPS is loosened or removed for any reason,
make sure all parts are reinstalled correctly. Tighten
the mounting bolts to the proper torque.
• The ROPS meets the requirements of ISO 3471.
OPERATING THE EXCAVATOR
1. Starting to operate the machine
• Get into and out of the machine safely. Always face
the machine. Always use handrails and available
steps and keep yourself well balanced. Do not hold
any of the control levers or switches. Do not jump
on or off the machine, whether stationary or in
motion.
• Start and control the machine only from the
operator's seat. The driver should not lean out of
their seat when the engine is running.
• Before starting the engine, make sure that lock
levers are in the LOCK position, all control levers
and pedals are in their “NEUTRAL” positions, and
the seat belt is fastened correctly.
Before starting the engine, make sure that the
control levers, travel lever, pedals, and other control
elements are not stuck and can be moved
smoothly.
If stuck, for example, a lever may fail to return,
possibly putting the user in danger.
If anything wrong is found, immediately pinpoint the
cause and correct it.
• Do not start the engine by jumping the starter
connections.
SAFE OPERATION

U10-5

Do not try to circumvent using the starter switch,
otherwise the engine could start suddenly and the
machine could move.
• Make sure that the dozer blade is in front of the
user (the dozer must be raised). If the levers are
activated with the dozer blade at the rear, the tracks
will move in the opposite direction of the drive
levers.
(A) Travel direction
(B) Drive levers
(C) Front
(D) Dozer blade
2. Working the machine
• Do not operate or idle engine in a non-ventilated
area. Carbon monoxide gas is colorless, odorless,
and deadly. If you experience the initial symptoms
of low to moderate CO poisoning, which include
headaches, fatigue, shortness of breath, nausea, or
dizziness, stop operation and seek medical
attention.
• Keep all safety equipment and covers in place.
Replace damaged or missing safety devices.
• Operate the machine so that it does not tip over.
Keep away from steep slopes and embankments.
Do not swing the bucket downhill. Lower the dozer
during digging. Keep the bucket as low as possible
while driving uphill. Turn slowly on slopes (at
reduced speed). Do not place the machine near the
edges of trenches and banks, as the earth can give
away due to the weight of the machine.
• Always pay close attention to the area to which the
machine is being moved.
• Keep enough distance from trench and bank edges.
3. Safety for children
Tragedy can occur if the operator is not alert to the
presence of children. Children generally are attracted to
machines and the work they do.
• Never assume that children will remain where you
last saw them.
• Keep children out of the work area and under the
watchful eye of another responsible adult.
• Be alert and shut your machine down if children
enter the work area.
• Never carry children on your machine. There is no
safe place for them to ride. They may fall off and be
run over or interfere with your control of the
machine.
• Never allow children to operate the machine even
under adult supervision.
• Never allow children to play on the machine or on
the attachments.
• Use extra caution when backing up. Look behind
and down to make sure the area is clear before
moving.
AFTER OPERATION
Before leaving the machine:
• Park the machine on a firm, flat and level surface. If
this is not possible, park across the slope.
Do not park the machine anywhere there are
combustible materials such as dried grass or straw.
• Lower the attachments and the dozer blade to the
ground.
• Stop the engine.
• Release the pressure from the hydraulic system.
• Lock all control levers.
• Remove the key.

MAINTENANCE
Before doing maintenance work on the machine, park
the machine on even and solid ground, lower the
attachment to the ground, stop the engine and release
pressure trapped in the hydraulic system by actuating
the levers. When dismantling hydraulic parts, make
sure that the hydraulic oil has cooled down sufficiently
to avoid burns.
Start maintenance work carefully, for example loosen a
plug slowly so that oil will not squirt out.
• Before doing work on the engine, the exhaust
system, the radiator, and the hydraulics, let the
machine cool down sufficiently.
• Turn off the engine at all times when filling with fuel.
Avoid spilling and overfilling of fuel.
• Smoking is prohibited while refueling or handling
the battery. Keep sparks and fire away from the fuel
tank and battery. Flammable gases escape from
the battery, especially during charging.
• Do not use or charge the refillable type battery if the
fluid level is below the [LOWER] (lower limit level)
mark. Otherwise, the battery component parts may
be prematurely deteriorated, which may shorten the
battery's service life or cause an explosion. Check
the fluid level regularly and add distilled water as
required so that the fluid level is between the
[UPPER] and [LOWER] levels.
• To avoid sparks from an accidental short circuit,
always disconnect the ground cable (-) of the
battery first and reconnect it last.
• Read and follow the instructions when starting with
an auxiliary battery.
(See STARTING WITH AN AUXILIARY BATTERY
on page 31.)
• Keep a first-aid box and a fire extinguisher at hand
at all times.
• Do not open the radiator cap before the radiator
has cooled down sufficiently.
First loosen the cap to the first stop and allow the
system enough time to release the remaining
pressure. Then loosen the cap completely.
• To avoid short circuit, always remove the ground
cable first when removing the battery, and attach
the positive cable first when installing the battery.
• Oil under high pressure can penetrate the skin and
may be harmful to your health if not treated
immediately.
• Leaking hydraulic fluid has enough pressure to
penetrate the skin and cause serious injuries.
Leakages from pin holes can be totally invisible. Do
not use hands for checking for leaks. Always use a
piece of wood or cardboard. It is strongly
recommended to use a face mask or eye
protection.
In the event of injuries caused by leaking hydraulic
fluid, contact a doctor immediately. This fluid can
cause gangrene or serious allergic reactions.
• To avoid environmental damage from acid and
heavy metals, do not throw the battery away.
• Observe all laws and regulations concerning the
disposal of used oil, coolants, solvents, hydraulic
fluids, battery acids, and batteries.
• To avoid fire, do not heat the hydraulic components
(tanks, pipes, hoses, cylinders) before they have
been drained and washed.
• Use a face mask or eye protection to protect the
eyes and respiratory system against dust and other
foreign particles.
• Securely support the machine with stands or
suitable blocking before working underneath. For
your safety, do not work under any hydraulically
SAFE OPERATION
U10-5

supported devices. They can settle, suddenly leak
down, or be accidentally lowered.
• Do not dismantle the spring of the track tensioner. If
dismantling is necessary, contact your Kubota
dealer where the machine was purchased, or other
competent service shop. The assembly must be
done according to the Kubota workshop manual
(WSM) for the product involved.
• When lifting the machine itself with an attachment,
place a safety block or safety post to prevent the
machine from rolling over. Keep the pilot control
lock lever in the LOCK position.
• Inspect ROPS for damage and if damage is found
contact your Kubota dealer for repairs.
• Kubota does not use components which contain
asbestos and recommends against the use of such
components.
Components containing asbestos should be
handled in accordance with applicable regulations
and industry practice.
• To avoid hazardous high voltage, turn the starter
switch to the [OFF] position if it is necessary to
check to repair the harness or connectors.
• To prevent personal injury or death, use explosion-
proof lighting when working on, inspecting, or using
fuel, oil, coolant, battery fluid, and so on.
If you do not use the explosion-proof lighting or if it
should break, it can ignite and cause fire, injury, or
death.
• Prohibit unauthorized persons from entering the
work area to prevent injury caused by debris flying
off of machine parts during grinding, welding, using
a hammer, or other tasks.
• Make sure that the work area is clear and safe.
Work on a firm, level surface with adequate lighting.
Work in well-ventilated area if you work indoors.
Make sure that the area is free from any potentially
dangerous conditions such as obstacles, slippery
surfaces, and so on.
• Make sure that the machine is clean and free of
debris.
– Always remove any debris from the machine
and clean it before performing maintenance or
repair work.
– Before washing or cleaning the machine using
water, stop engine and make sure that all of the
electrical parts and devices are covered. Any
water seepage into the electrical wiring on the
machine can cause a short circuit or cause the
controls to malfunction. Never use water or
steam to clean any of the electrical parts and
devices, such as the battery, the sensors, or the
connectors.
• Always make sure that the engine is stopped before
performing any maintenance or repairs.
– Do not lubricate or mechanically adjust while
the machine is in motion or while the engine is
running even if stationary.
– Always stay clear of moving parts. Clothing,
hands, or other parts of the body can become
caught in moving parts of the machine and
cause personal injury or death.
– Make sure to avoid any rotating fans, V-belt,
and other moving parts. Never insert tools,
fingers, hands, and so on while these parts are
running.
• Exercise caution when refueling.
– Never smoke cigarettes or permit the use of fire
while refueling or in the vicinity of refueling.
– Always make sure that the engine is off and
cool before removing the fuel cap to refuel the
tank. Avoid getting fuel on any hot components.
– Keep control of the fuel-filler-nozzle while
refueling.
SAFE OPERATION

U10-5

– Never overfill the tank with fuel. Leave room for
thermal expansion.
– Always remove any excess or spilled fuel
immediately.
– Always make sure that the fuel-tank-cap is
securely reinstalled.
Replace the fuel-tank-cap only with a
manufacturer-approved cap whenever it
becomes damaged. Use of the wrong type of
cap may not allow for proper venting, causing
pressure in the tank to build up.
– Never use fuel to clean the machine.
– Always use the correct type of fuel for the
machine and the temperature in which it is
being operated.
– Always use a properly grounded fueling system.
• Use caution when working around hot and
pressurized components.
– Always allow the engine to cool sufficiently
before performing any maintenance, inspection,
or repairs.
– Never touch any parts such as the engine, the
muffler, the radiator, the hydraulic lines, the
sliding parts, and so on as they may be very hot
immediately after the machine has been
running and can cause burning. Allow the
engine, the muffler, the radiator, the hydraulic
lines, the sliding parts, and so on to cool
sufficiently before touching them.
– Always use sufficient care whenever removing
the caps and plugs on the coolant, oil, and
hydraulic fluid as they are hot and pressurized
and can causing burning and injury from
spraying of hot fluid.
• Make sure that pressure from all of systems is
sufficiently released before performing any
maintenance or repairs. Oil or other fluids could be
released when caps or filters are removed before
the pressure has been stabilized in the hydraulic
system.
– Gradually release internal pressure build-up by
standing out of the line of any possible spray
and slowly removing plugs, screws, or
disconnect hoses.
• Always use care whenever using grease that is
pressurized.
– Always follow the proper procedure to adjust
tension.
Grease in the track adjuster is pressurized and
improper release can cause the discharge valve
to fly off, causing personal injury or death.
– Always loosen the grease fitting slowly.
– Avoid standing in front of, or putting any parts of
the body in the line of the grease fitting.
– If no grease is released when the grease fitting
is loosened, the machine has a malfunction. Do
not perform repairs of any kind yourself and
contact the nearest dealer for repairs. If no
grease is released when the grease fitting is
loosened, any operation of the machine can be
very dangerous.
• Always carefully check the machine after

the parts. Gradually speed up the engine from a low
speed to higher speed to check operation.
•Waste material:
– Always make sure that any material and waste
products from the repair and maintenance of
the machine are collected into proper
containers using a funnel, or other device.
Dispose of waste material properly to avoid
pollution and contamination of the environment.
– Consult local regulations and codes when
disposing of oil, fuel, engine coolant, refrigerant,
solvents, filters, batteries, and any other
potentially harmful and hazardous material or
substance.
Fire prevention
The machine and some attachments have components
that are at high temperatures under normal operating
conditions. The primary source of high temperatures is
the engine and exhaust system. The electrical system,
if damaged or incorrectly maintained, can be a source
of arcing or sparks.
The following fire prevention guidelines will help to
keep your equipment up and running efficiently and
keep the risk of fire to a minimum.
• Blow off all accumulated debris near hot engine
exhaust components such as turbocharger and
exhaust manifold as well as exhaust pipes and
muffler more frequently when working in severe
conditions.
• Clean out all accumulated flammable debris such
as leaves, straw, pine needles, branches, bark,
small wood chips, and any other combustible
materials from inside the machine belly pans or
lower unit structures as well as from area in
proximity to the engine.
• After use and pressure-washing, make sure there is
nothing flammable near the exhaust pipe. Grass,
twigs, or other organic debris under the hood may
cause fire.
• Inspect all fuel lines and hydraulic hoses for wear or
deterioration. Replace them immediately if they
begin to leak.
• Examine electrical wiring and connectors frequently
for damage. Repair any wires that are loose or
frayed before operating the machine. Clean all
electrical connections and tighten all electrical
connections as necessary.
• Inspect the exhaust system daily for any signs of
leakage. Check for broken pipes and muffler and
also for loose or missing bolts, nuts and clamps. If
any exhaust leaks or fractured parts are found,
repairs must be completed prior to operation.
• Always keep a multipurpose fire extinguisher on or
near the machine. Be familiar with the operation of
the fire extinguisher.
