Read and understand this section carefully,
before operating the excavator.
Every user, however experienced, should
carefully read and understand this section
and those of the attachments and accessories
before taking the excavator into operation.
The owner is obliged to inform the operators
of these instruction in detail.
Keep this manual in the storage place. (See
"Keeping the Operator's Manual" in the
BEFORE START section.)
SAFE OPERATION
1. BEFORE OPERATION
1. Make yourself acquainted with the
excavator and be aware of its limits.
Read this operator’s manual carefully
before starting the excavator.
2. Obey the danger, warning and caution
labels on the machine.
3. For your safety, a ROPS/OPG (Top Guard
Level I) with a seat belt is installed by
KUBOTA.
A ROPS: Roll-Over Protective Structure
A OPG (Top Guard Level I): Operator
Protective Guards of Top Guard Level I
OPG (Top Guard Level I) in accordance
with ISO10262 is equivalent in defi nition
to FOPS (Falling Object Protective
Structure).
Always use the seat belt when the
machine is equipped with a ROPS/OPG
(Top Guard Level I) as this combination
will reduce the risk of serious injury or
death, should the excavator be upset or
falling objects occur.
Do not modify any structural members
of the ROPS/OPG (Top Guard Level I)
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/
OPG (Top Guard Level I) is loosened or
removed for any reason, make sure all
parts are reinstalled correctly. Tighten
mounting bolts to proper torque.
4. ROPS meets requirements of ISO 3471.
OPG (Top Guard Level I) meets
requirements of OSHA 1926·1003/ISO
10262.
5. The seat belt must be inspected regularly
and replaced if frayed or damaged.
(1) Seat belt

6. Track can be set at the narrow width 39in.
(990mm) and the standard width 49in.
(1240mm).
(for details see “OPERATION OF TRACK
WIDTH CHANGE AND DOZER”)
Do not operate in narrow track width
39in. (990mm), it makes risk of the
excavator tipping over, operate always
in standard track width 49in. (1240mm),
except to pass through narrow space on
a even ground.
7. Do not use the excavator under the
infl uence of alcohol, medication as well
as other substances. Fatigue is also
dangerous.
8. Check the surroundings carefully before
using the excavator or when attachments
are being attached.
Pay attention to the overhead clearance
with electric wires.
During excavator use do not allow any
persons within the working range.
9. Do not allow other persons to use
the machine before having informed
him on the exact operation and work
instructions, and be assured that the
operator’s manual has been read and
understood.
10. Do not wear baggy, torn or too large
clothing when working with the
excavator. Clothing can get caught in
rotating parts or control elements which
can cause accidents or injuries. Wear
adequate safety clothing, e.g. safety
helmet, safety shoes, eye protection,
ear protection, working gloves, etc., as
necessary and as prescribed by law or
statutes.
Check for pipes and buried cables.
Check for hidden holes, hindrances, soft
underground and overhangs.

11. Do not allow passengers to get on any
part of the excavator seat throughout
operation.
12. Check mechanical parts for correct
adjustments and wear. Exchange worn
or damaged parts immediately.
13. Keep your excavator clean. Heavy
soiling, grease, dust and grass can
infl ame and cause accidents or injuries.
14. Use only KUBOTA authorized
attachments.
15. Before starting the excavator, be
absolutely sure that the excavator has
been fi lled with fuel, lubricated, greased
and undergone other maintenance
work.
16. Do not modify the excavator, otherwise
it could lead to unforeseen safety
problems.
17. Make sure attachments, particulary
those utilizing quick attach systems, are
securely mounted.
2. STARTING OF THE EXCAVATOR
1. 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 Ievers and switches. Do
not jump on or off the machine, whether
stationary or in motion.
2. Start and control the excavator only from
the operator’s seat. The driver should not
lean out of his seat when the engine is
running.
3. Before starting the engine, make sure
that all control levers (including auxiliary
control levers) are in their neutral
positions.
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 you in danger.
If anything wrong is found, immediately
pinpoint the cause and correct it.
4. Do not start the engine by jumping
the starter connections. Do not try to
circumvent using the starter switch,
otherwise the engine could start suddenly
and the excavator could move.
4
5. Make sure that the dozer is on the front
side. (The dozer must be raised.) If the
levers are activated with the dozer on the
rear end, the driving direction is in the
opposite direction of the drive levers.
6. Do not run the engine in closed or badly
ventilated rooms. Carbon monoxide is
colourless, odourless and deadly.
Safety for children
Tragedy can occur if the operator is not
alert to the presence of children. Children
generally are attached to machines and the
work they do.
1. Never assume that children will remain
where you last saw them.
2. Keep children out of the work area
and under the watchful eye of another
responsible adult.
3. Be alert and shut your machine down if
children enter the work area.
4. 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.
5. Never allow children to operate the
machine even under adult supervision.
6. Never allow children to play on the
machine or on the attachments.
7. Use extra caution when backing up. Look
behind and down to make sure the area
clear before moving.
8. When parking your machine, if at all
possible, park on a fi rm, fl at and level
surface; if not, park across a slope. Lower
the bucket and dozer to the ground,
remove the key place the control lock
levers in the locked position from the
ignition before you leave.
7. Keep all safety equipment and covers
in place. Replace damaged or missing
safety device.
8. Precautions against tipping over. In order
to secure safe operation, keep away from
steep slopes and embankments. Do not
swing the bucket downwards. Lower the
dozer during digging. Keep the bucket as
low as possible while driving upwards.
Turn slowly on slopes (do not fast). Do
not keep the excavator near the edges
of trenches and banks, as the earth
can give away due to the weight of the
excavator.
9. Watch out at all times where the
excavator is being moved to. Keep an
eye out for hindrances.
10. Keep enough distance from trench and
bank edges.
5
3. AFTER OPERATION
Before leaving the machine,
Bring the excavater on a fi rm, fl at and
level surface.
Lower the attachments and the dozer
blade on the ground.
Stop the engine.
Lock all control levers.
Remove the key.
4. SAFE LOADING AND TRANSPORT
OF THE EXCAVATOR
1. Observe all regulations concerning the
transport of excavators on public roads.
2. Use adequately long and robust ramps
when loading on a truck. (for details see
“TRANSPORTING THE EXCAVATOR ON
A TRUCK”)
3. Do not change the running direction
and to avoid a tipping over, do not try to
swing the attachment crosswise to the
loading ramps.
4. After loading of the excavator on a truck,
engage the swing lock pin.
Lower the attachment on the loading
plane and release the pressure from the
hydraulic system.
Block the tracks with blocks and wire
down the excavator. After loading the
excavator on a truck, tie down the
undercarriage of the excavator with a
strong steel wire on the truck.

5. Do not brake abruptly with the excavator
loaded. Mortal accidents could happen.
6. If the excavator is used to tow another
machine, the load must be smaller than
the strength of the hook.
7. Do not use hooks on the roof of canopy
for lifting the excavator.
Max. drawbar pull at
coupling hook
Max. vertical load at
coupling hook
32.3 kN
2.7 kN
5. MAINTENANCE
Before doing maintenance work on the
excavator, place the machine on a fi rm, fl at
and level surface, Iower the attachments on
the ground, stop the engine then remove
the key and release the cylinder pressure
by actuating the levers. When dismantling
hydraulic parts, make sure that the hydraulic
oil has cooled down suffi ciently to avoid
burns.
Start maintenance work carefully, e.g. loosen
screws slowly so that oil will not squirt out.
1. Before doing work on the engine, the
exhaust system, the radiator and the
hydraulics, let the excavator cool down
suffi ciently.
2. Turn off the engine at all times when
fi lling with fuel. Avoid spilling and overfi lling of fuel.
3. Smoking is prohibited while tanking
and handling the battery! Keep sparks
and fi re away from the fuel tank and
battery. Flammable gases escape from
the battery, especially during charging.
4. Do not use or charge the refi llable
type battery if the fl uid level is below
the LOWER (lower limit level) mark.
Otherwise, the battery component parts
may prematurely deteriorate, which
may shorten the battery's service life
or cause an explosion. Check the fl uid
level regularly and add distilled water as
required so that the fl uid level is between
the UPPER and LOWER levels.
5. Read and follow “STARTING WITH AN
AUXILIARY BATTERY” in “OPERATION
OF THE ENGINE”, when starting with an
auxiliary battery.
6. To avoid short-circuiting the battery,
always remove the earth cable fi rst and
attach the plus cable fi rst.
7. Keep a fi r st-aid box and a fi re extinguisher
at hand at all times.
8. Do not open the radiator cap before the
radiator has cooled down suffi ciently.
First loosen the cap to the fi rst stop and
allow the system enough time to release
the remaining pressure. Then loosen the
cap completely.
9. Leaking hydraulic fl uid has enough
pressure to penetrate the skin and cause
serious injuries. Leakages from pin
holes can be totally invisible. Do not use
the bare hand for checking on possible
leakages. Always use a piece of wood or
cardboard. It is strongly recommended
to use a face mask or eye protection.
Should injuries occur with leaking
hydraulic fl uid, contact a doctor
immediately. This fl uid can cause
gangrene or serious allergic reactions.
10. To avoid leakage of battery acid which
contains heavy metals, do not throw the
battery away.
11. Observe all laws and regulations
concerning the disposal of used oil,
coolants, solvents, hydraulic fl uids,
battery acids and batteries.
12. To avoid fi re, do not heat the hydraulic
components (tanks, pipes, hoses,
cylinders) before they are drained and
washed.
7
13. Use a face mask or eye protection to
protect the eyes and respiratory system
against dust and other foreign particles.
14. Securely support excavator with stands
or suitable blocking before working
underneath. For your safety, do not
work under any hydraulically supported
devices. They can settle, suddenly leak
down, or be accidentally lowered.
15. Do not crawl under the excavator if the
excavator is only supported by the boom
and arm or the dozer. The excavator can
tip over or lower itself due to hydraulic
pressure loss. Always use safety struts
or other appropriate supports.
16. KUBOTA uses no parts which are lined
with asbestos. Do not use these kind of
parts even if they can be installed.
17. Fire prevention
Excavator 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 fi re prevention guidelines
will help to keep your equipment up and
running effi ciently and keep the risk of
fi re 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 muffl er
more frequently when working in severe
conditions.
Clean out all accumulated fl ammable
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.
Inspect all fuel lines and hydraulic hoses
for wear or for 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 muffl er 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 fi re
extinguisher on or near the machine.
Be familiar with the operation of the fi re
extinguisher.
