-1SAFE OPERATION

SAFE OPERATION

The best insurance against accidents is to abide
by the safety regulations.

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
instructions in detail.
Keep this manual in the toolbox.

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, ROPS (Roll-Over Protective

Structure) with a seat belt is installed.
Always use seat belt when the machine is
equipped with a ROPS.
Do not modify structual 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. Tighten
mounting bolts to proper torque.

4. The seat belt must be inspected regularly

and replaced if damaged.

5. Track can be set at the narrow width 2 ft.3.6
in. (700mm) and the standard width 2 ft.9.9
in. (860mm).
(for details see "OPERATION OF TRACK
WIDTH CHANGE AND DOZER")
Do not operate in narrow track width 2 ft.3.6
in. (700mm), there is a risk of the excavator
tipping over, always operate in standard
track width 2 ft.9.9 in. (860mm), except to
pass through a narrow space on even
ground.

6. Do not use the excavator under the
influence of alcohol, medication or other
substances. Fatigue is also dangerous.

7. Check the surroundings carefully before
using the excavator or when attachments
are being attached.

A Pay attention to the overhead clearance with

electric wires.

A Check for pipes and buried cables.
A Check for hidden holes, hindrances, soft

ground and overhangs.

(1) Seat belt

-2 SAFE OPERATION

A During excavator use do not allow any

persons within the working range.

8. 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.

9. 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 laws or
statutes.

10.Do not allow passengers to get on any part
of the excavator seat during operation.

11.Check mechanical parts for correct
adjustments and wear. Exchange worn or
damaged parts immediately. Check nuts
and bolts regularly for tight fitment.
(for details see "Care and Maintenance").

12.Keep your excavator clean. Heavy soiling,
grease, dust and grass can inflame and
cause accidents or injuries.

13.Use only KUBOTA authorized attachments.

14.Before starting the excavator, be absolutely
sure that the excavator has been filled with
fuel, lubricated, greased and undergone
other maintenance work.

15.Do not modify the excavator, otherwise it
could lead to unforeseen safety problems.

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.

(1) Helmet
(2) Clothing fit for work
(3) Tight seams
(4) Good grip footwear
(5) Well fitting cuffs
(6) Working gloves
(7) Straw hat
(8) Towel
(9) Baggy trousers
(10) Loose cuffs on shirt
(11) Baggy shirt
(12) Rubber sandals

-3SAFE OPERATION

5. Make sure that the dozer is on the front side.
(The dozer must be raised.) If the swing
frame has been turned 180 , i.e. the dozer
is, seen from the operator, "behind", then the
travel direction is opposite to the drive
direction of the levers (when activating the
drive lever forwards, the excavator, seen
from the operator, will move backwards).

6. Do not run the engine in closed or badly
ventilated rooms. Carbon monoxide is
colourless, odourless and deadly.

7. Keep all safety equipment and covers in
place. Replace damaged or missing safety
devices.

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 keep the excavator
near the edges of trenches and banks, as
the earth can give way 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.

C 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.

11.Never assume that children will remain
where you last saw them.

12.Keep children out of the work area and
under the watchful eye of another
responsible adult.

13.Be alert and shut your machine down if
children enter the work area.

14.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.

15.Never allow children to operate the machine
even under adult supervision.

16.Never allow children to play on the machine
or on the implement.

17.Use extra caution when backing up, look
behind and down-make sure area is clear
before moving.

18.When parking your machine if at all possible
park on a firm, flat and level surface; if not,
park across a slope. Set the parking
brake(s), lower the implements to the
ground, remove the key from the ignition and
lock the cab door (if equipped) and chock the
crawlers or the wheels.

-4 SAFE OPERATION

3. AFTER OPERATION

Before leaving the machine,

A Bring the excavator to hard even ground.
A Lower the attachments and the dozer blade

on the ground.

A Stop the engine.
A Lock all control levers.
A 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 crawlers 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. Fatal accidents could happen.

(1) Lock lever (A) "Lock"

(B) "Unlock"

(1) Swing lock pin (A) "Lock"

(B) "Unlock"

-5SAFE OPERATION

6. If the excavator is to tow another machine,
the load must be smaller than the strength of
the hook.

5. MAINTENANCE

Before doing maintenance work on the
excavator, place the machine on even solid
ground, Iower the attachments on the ground,
stop the engine and release the cylinder
pressure 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, 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
sufficiently.

2. Turn off the engine at all times when filling
with fuel. Avoid spilling and over-filling of
fuel.

3. Smoking is prohibited while fuelling and
handling the battery! Keep sparks and fire
away from the fuel tank and battery.
Flammable gases escape from the battery,
especially during charging.

4. 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 prematurely
deteriorate, 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.

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 first and attach the
plus cable first.

7. Keep a first-aid box and a fire extinguisher at
hand at all times.

8. 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.

9. 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 the bare hand for
checking on possible leakages. Always use
a piece of wood or cardboard. It is strongly
recommended you use a face mask or eye
protection.
Should injuries occur with leaking hydraulic
fluid, contact a doctor immediately. This fluid
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 fluids, battery acids and batteries.

12.To avoid fire, do not heat the hydraulic
components (tanks, pipes, hoses, cylinders)
before they have been drained and washed.

Max. drawbar pull at
coupling hook

7935 lbs. (35.3 kN)

Max. vertical load at
coupling hook

922 lbs. (4.1 kN)

-6 SAFE OPERATION

13.Use a face mask or eye protection to protect
the eyes and respiratory system against
dust and other foreign particles.

14.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.

15.KUBOTA uses no parts which are lined with
asbestos. Do not use these kind of parts
even if they can be installed.

16.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 fire prevention guidelines will
help to keep your equipment up and running
efficiently and keep the risk of fire to a
minimum.

A 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.

A 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.

A Inspect all fuel lines and hydraulic hoses for

wear or for deterioration. Replace them
immediately if they begin to leak.

A 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.

A 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.

A Always keep a multipurpose fire

extinguisher on or near the machine. Be
familiar with the operation of the fire
extinguisher.
