-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.

11OPERATION OF THE ENGINE

BObserve Following Guidelines

when Starting with an Auxiliary
Battery.

1. Bring the second machine with the same
battery voltage as near as possible to the
excavator.
THE MACHINES MUST NOT COME IN
CONTACT WITH EACH OTHER.

2. Put the levers and pedals of both vehicles in
the neutral position and the lock lever in the
"Lock" position.

3. Wear eye protection and rubber gloves.

4. Remove the battery caps from both
batteries. (If present)

5. Cover the battery opening with a cloth. Make
sure that the cloth does not touch the battery
terminals.

6. Connect the terminal of the red jump lead
with the plus terminal of the empty battery
and connect the other end of the cable to the
plus terminal of the auxiliary battery.

7. Connect the black cable to the minus
terminal of the auxiliary battery.

8. Connect the other end of the black cable
(coming from the auxiliary battery) with the
excavator frame as far away as possible
from the empty battery.

9. Start the engine of the second machine and
let it run for a while. Start the excavator with
the empty battery.

10.Disconnect the jump leads in the opposite
sequence (Steps 8, 7, 6).

11.Remove the cloth and replace the battery
caps.

A This excavator has a negative earthed 12

Volt starting system.

A Only use the same voltage when using an

auxiliary battery.

A Using a higher voltage will cause serious

damage to the electrical system. When
using an auxiliary battery, only the
compatible (same) voltage is permissible.

BPrecautions in case of overheat

To avoid personal injury:
A Do not open the radiator cap during

and just after operation. Hot water
may gush out and get you burned.
Wait long enough until the radiator
cools down.

If by any change cooling water gets heated up
to the boiling point or over (overheated), the
whistle at the reserve tank drain hose end
blows. In such case, take the following steps.

1. Stop operation in a safe condition.
(Disconnect the engine's load.)

2. Do not stop the engine suddenly. Keep the
engine idling under no load for about 5
minutes and turn it off.

3. Keep yourself enough away from the
machine for another 10 minutes or while
steam is given off.

4. Make sure there is no hazard of getting
burned. Pinpoint and remove the cause of
overheat, referring to
"TROUBLESHOOTING". Then get the
engine restarted.

EXCAVATOR OPERATION

CONTROL OBSERVATIONS
DURING OPERATION

BStop the Engine immediately if:

A Sudden increase or decrease in engine

revolution occurs.

A Sudden abnormal noises occur.
A Exhaust gases turn suddenly very dark.

Make following control observations during
operation to be sure that everything functions
normally.

BAlarm Lamps

Should an alarm lamp light up during operation,
stop the engine immediately and as described
below, check for the cause. Do not use the
excavator when an alarm lamp is lit up.
Explanation of alarm lamp is described as
"Malfunction Indicator (Quick Diagnosis)" under
"STARTING THE ENGINE" in "OPERATION
OF THE ENGINE".

Engine Oil Pressure
When the engine oil pressure sinks below the
prescribed level, the alarm lamp will light up.
Should this occur during operation and not go
out even if the engine revolution is increased by
1000 rpm, check the engine oil level. (see
"Check Engine Oil Level" under "DAILY
CHECKS" in "MAINTENANCE").

Battery Charge
If the battery is not charged by the generator,
the alarm lamp will light up. Should this occur
during operation, check the electrical system or
contact your KUBOTA dealer.
(see "TROUBLESHOOTING")

RUNNING-IN OF THE NEW
EXCAVATOR

The operation and care of the new excavator
influences its life span. Your new excavator has
been carefully checked and tested before
leaving the factory. In spite of this, all movable
components must run-in during the first 50
work hours. Do not work with full revolution and
full loads during this period. It is most important
to run-in your excavator properly in order to
achieve its full performance and longevity.
During the running-in, the following points
should be adhered to in all cases.

BDo not Work with Full Revolutions

or Full Loads during the First 50
Working Hours.

A Let the engine warm up sufficiently in the

cold season.

A Do not let the engine rev-up more than

necessary.

BOil Change in the Run-in Stage.

The lubrication oil plays a specially important
role during the run-in phase of the excavator.
The numerous movable parts are not yet run-in,
so that many fine metal particles can develop
and cause damage or shorten the lifetime of
many components. Pay attention to the oil­change intervals and execute them sooner
rather than later as necessary. See the subject
"Care and Maintenance" for more details on the
oil-change intervals.

17EXCAVATOR OPERATION

*NOTE:

A See "SWIVEL MOVEMENT AND SWING

MOVEMENT".

OPERATION OF THE BOOM

To raise the boom, pull the attachment control
lever back.
The boom is equipped with a cushion cylinder
which prevents excavated material in the bucket
from fall-in out. By low hydraulic oil temperature,
(e.g. right after starting the engine) the
cushioning function will only be effected after a
certain delay (approx. 3 to 5 seconds). This
condition results from the viscosity of the
hydraulic oil and is no sign of a malfunction.

A When lowering the boom, make sure that it

does not hit the dozer and that the bucket
teeth do not touch the dozer.

OPERATION OF THE ARM

Pull back the left attachment control lever and
the arm will be pulled in. To move the arm out,
push the control lever towards the front.

A When pulling in the arm, the movement may

stop for a short moment when the arm is in
its vertical position. This is caused by the
fact that at this position the maximum load
for the arm and bucket is reached, and the
hydraulic pressure in the cylinder is not high
enough. This is a characteristic of the
hydraulic system and is not a sign of a
malfunction.

OPERATION OF BUCKET

To dig with the bucket, move the right
attachment control lever from the neutral
position towards the left. Moving the control
lever towards the right pushes the bucket
outwards and dumps its contents.

A When working in groups, always let

the others know what you are going to
do before you do it.

A Keep away from the working area.

A Do not operate the left attachment

control lever abruptly from the right to
the left (or vice versa). Because of the law
of inertia, this causes an impact load on
the swing gear and the swing motor.
Additionally, the lifetime of the excavator
will be shortened.

A Unlock the swing lock pin before

carrying out swivel operations.

1. Tilt the control lever to the left and the upper
structure will turn to the left.

IMPORTANT INFORMATION ON
EXCAVATOR OPERATION

To avoid personal injury:
A After work, clean the machine and

lubricate all movable parts.

A Check oil level.

A Do not try to crush concrete or boulders

using side swings with the bucket. Also
avoid using side sweeps of the bucket to
move earth piles.

A Under all circumstances avoid the following

operations:
A Excavation using the gravitational impact

of the machine.

A Compacting of gravel or soil using the

dropping action of the bucket.

A Excavation using the travelling power of

the machine.

A Do not try to drop or shake of soil adhering

to the bucket in the manner shown in the
explanation below. This can cause damage
to the machine.
Adhering soil can be shaken off when the
bucket is being emptied by moving the
bucket out to the maximum stroke of the
cylinder. Should this not suffice, swing out
the arm as far as possible and operate the
bucket back and forth.

A Do not hit the dozer with the boom cylinder!

Make sure that the boom cylinder does not
hit the dozer when carrying out deep
excavation. If necessary swivel the upper
structure so that the dozer is at the back of
the machine.

A Pay attention when pulling in the bucket!

When pulling in the bucket (for driving or
transportation) avoid hitting the dozer.

A Avoid collisions!

When moving the excavator, pay attention
so that the dozer does not collide with
obstructions such as boulders etc..
Such collisions substantially shorten the life
span of the dozer and the cylinder.

A Support the machine correctly!

When stabilizing the machine with the dozer,
Iower the whole dozer fully on to the ground.

A If the water or mud level reaches higher than

the top of the tracks, the swivel bearing,
swivel motor gear and ring gear may be
exposed to mud, water and other foreign
objects.
The excavator must be properly pressure
washed after each use.
A Thoroughly clean the area around the

swivel bearing, swivel motor gear and
ring gear to remove foreign objects.

A Inspect the swivel motor oil sump (if

equipped) for water contamination. If
water is present, refer to operator's

BBattery Service

To avoid personal injury:
A Batteries contain sulphuric acid

which can cause severe burns. Avoid
all contact with skin, eyes or clothing.
Antidote - External: Rinse with plenty
of water. Internal: Drink large
quantities of water or milk.
Call a physician immediately. Eyes:
Rinse with plenty of water for 15
minutes and get prompt medical
attention. Keep batteries out of the
reach of children.

A Before inspection or dismounting the

battery, be sure to turn of the engine
and turn the starter switch to the
"OFF" position.

A When removing the battery, always

disconnect the negative ground cable
first. The reverse when installing a

terminal first.

A Do not check battery charge by

placing a metal object across the
terminals.
Use a voltmeter or hydrometer.

1. Make sure each electrolyte level is to the
bottom of vent wells. If necessary add
distilled water in a well-ventilated area.

2. The water in the electrolyte evaporates
during recharging. Liquid shortage damages
the battery. Excessive liquid spills over and
damages the excavator body.

3. To slow charge the battery, connect the
battery positive terminal to the charge
positive terminal and the negative to the
negative, then recharge in the standard
fashion.

ADJUSTMENT OF CRAWLERS

C To loosen the crawlers, follow the

following procedure:

To avoid personal injury:
A Do not loosen the grease fitting

completely or too quickly. Otherwise
grease under high pressure in the
tension cylinder could squirt out.

A Do not crawl under the excavator.

1. Using a socket wrench, loosen the grease
fitting a few turns.

2. When grease oozes out from the thread,
rotate the crawler and loosen the crawler in
the lifted position (see illustration).

After adjustment is completed:

Using the socket wrench, tighten the grease
fitting.
Tightening torque must be between 72.3 to 79.6
ft-lbs (98 to 108 N-m, 10 to 11 kgf-m).

A If the crawlers are too tight, wear is

increased.

A If the crawlers are too loose, the crawler

shoes may collide with the sprocket, and
wear is increased.
The crawler may dislocate or come off.

A Clean the crawler after every use.
A Should the crawler tension be heightened

due to mud sticking, lift the crawler with the
help of the boom, arm and bucket, idle the
engine and remove the mud from the
crawler, especially from the openings of the
link plate, carefully.

C Tension the crawlers as specified:

1. Apply grease (2) to the grease fitting (1).

52 OTHER ADJUSTMENTS AND REPLACEMENTS

2. Tension the crawler in the lifted position, so
that the distance "A" (clearance between the
track roller and the inside surface of the
crawler) is 0.39 to 0.59 in. (10 to 15 mm)
(see illustration), (In this case, the crawler
seam is positioned on the top centre
between the idler and the sprocket.

To avoid serious injury or death:
A Do not work under the machine in this

condition.

A For your safety do not rely on

hydraulically supported devices, they
may leak down suddenly drop or be
accidentally lowered.

A Make sure that no obstacles, such as

stones, are caught in the crawler. Remove
such obstacles before adjusting the crawler
tension.

A Crawler seam

The ends of the rubber crawler are joined
with a seam. When adjusting the crawlers,
the seam must be positioned on the top
centre between the idler and the sprocket.

If the seam is positioned incorrectly, the
crawlers will be tensioned to loosely, and a
further readjustment will be necessary.

A Rotate the crawler after adjustment one to

two times to check the tension.

A Additionally the following points are to be

observed when adjusting rubber crawlers.
(1) If the crawler slackens more than 0.98

in. (25 mm), readjust them.

(2) Check crawler tension 30 hours after

initial use and readjust if necessary.
Check and adjust thereafter every 50
service hours.

BSpecial Information when Using

Rubber Crawlers

1. When turning, preferably make a slow swing
turn. Avoid spin turns to lessen lug wear and
ingress of dirt.

2. The relief valve may be activated if too much
dirt and sand clog the crawlers. In this case
move the machine for a short distance
straight backwards to let the earth and sand
fall off, then a turn can be made.

3. Avoid using rubber crawler on riverbeds,
stony underground, ferro-concrete and iron
plates. The rubber can be damaged as well
as crawler wear increasing.

56 OPERATION IN COLD WEATHER CONDITIONS

OPERATION IN COLD WEATHER CONDITIONS

PREPARATION FOR OPERATION
IN COLD WEATHER

1. Replace engine oil and hydraulic oil with
those of viscosities suitable for cold weather.

2. In cold weather, battery power drops, and
the battery fluid may freeze if the battery is
not sufficiently charged. To prevent the
battery fluid from freezing, be sure to keep
the battery charged at least 75% or more of
its capacity after operation. To ease next
starting, it is recommended to keep the
battery stored in closed or heated rooms. If
the battery fluid level is too low, do not add
after operation, but add with the engine
running before the next operation.

3. Add anti-freeze to coolant in the radiator and
reserve tank, if the ambient temperature is
expected to drop below 32 F (0 C). Mixing
ratio of water and anti-freeze depends on
the expected ambient temperature.
However, a 50/50 mix is recommended.

A Mixing ratio between water and anti-freeze

A Use permanent anti-freeze or long-life

coolant.

A Drain the coolant completely and clean the

radiator inside then fill with the water and
anti-freeze mixture.

A As the anti-freeze also acts as an anti-

corrosive, it is not necessary to add an
additive to the water and anti-freeze mixture.

A See "Coolant check" under "DAILY

CHECKS" in "MAINTENANCE" for radiator
fill volumes.

PROCEDURE AFTER WORK
CARRIED OUT

Clean the excavator thoroughly after work and
wipe dry. Otherwise mud and earth on the
crawlers could freeze if the temperature drops
below the 32 F (0 C) mark. Operation of the
excavator is then not possible. Store the
excavator in a dry place; if not possible, store on
wooden planks or on mats. If the excavator is
kept on damp or muddy ground, the crawlers
could freeze overnight. Operation of the
excavator is then not possible. Furthermore the
reduction gear may be damaged.
Additionally, the hydraulic cylinders piston rods
must be rubbed dry. Otherwise severe damage
could occur if dirty water seeps through the
seals.

LONG STORAGE

To avoid personal injury:

A Do not clean the excavator with the engine running.
A To avoid the danger of exhaust fume poisoning, do not operate the engine in a closed

building without proper ventilation.

A When storing, remove the key from the starter switch to avoid unauthorized persons from

operating the excavator and getting injured.

B Should the Excavator be Stored for a Longer Period of Time, Observe

Following Procedures:

1. The whole excavator should be cleaned thoroughly and in all cases stored indoors. If the excavator
has to be kept outdoors, Iay out wooden planks on even ground, place the excavator on the planks
and cover completely.

2. Do an oil change and grease the excavator.

3. Heavily grease the visible sections of the piston rods.

4. Remove the battery and store indoors.

5. If it is expected that the temperature will sink below the 32 F (0 C) mark, add anti-freeze or drain
coolant completely.

A Wash the excavator after stopping the engine.

If you wash the excavator while running the engine, water may get into the air cleaner through the
intakes causing engine problems.
Carefully, wash but do not splash water over the air cleaner.

B Observe Following Procedures when the Machine is to be Operated after

Long Storage.

1. Wipe off the grease from the hydraulic cylinder rods.

2. Turn on the engine and activate the attachments and the drive mechanisms without load in order to
circulate the hydraulic oil . (If the machine is stored for longer than one month, undertake steps (1)
and (2) once every month)

58 LONG STORAGE

Periodic replacement of important component parts

To ensure safety in operation, you are strongly requested to inspect and service the machine at regular
intervals. For added safety, ask your KUBOTA dealer to replace the following important component
parts.
These parts are prone to degradation in material or subject to wear and tear with time. It is difficult to
judge how much they have been affected at regular inspection. It is therefore necessary to replace them
with new ones, whether wear is visible or not after a specified time of use.
If any of them is found worn even before the specified use, it must be repaired or replaced the same
way as other parts.
If any of the hose clamps is found deformed or cracked, the hose clamp must also be replaced.
For the hydraulic hoses other than the ones to be replaced periodically, inspect them for the following
points. If found unusual, tighten them up, replace them.
When replacing the hydraulic hoses, change their O rings and sealings with new ones.
For replacement of the important parts, contact your KUBOTA dealer.

A At the following periodic inspections, check the fuel hoses and hydraulic hoses as well.

62 LIFTING CAPACITY

LIFTING CAPACITY

1. The lifting capacities are based on ISO 10567 and do not exceed 75% of the static tilt load of the
machine or 87% of the hydraulic lifting capacity of the machine.

2. The strokes are as follows.
(1) The load point corresponds to the front bolt part of the arm.
(2) The machine positions are (i) over-front (Blade up), (ii) over-front (Blade down), and (iii) over-

side.

(3) The operating cylinder is the boom cylinder.

3. The bucket of the excavator, the hook, the sling and other lifting accessories are taken into
consideration for the loads.

Machine conditions:
No bucket, all others according to standard regulations.

To avoid personal injury or death:
A It is forbidden to lift loads greater than those values mentioned in the lifting capacity

tables.

A The values mentioned in the table are valid only on even, hard ground. When lifting on

soft ground, the machine 'can tilt over due to the fact that the load is concentrated only
on one side of the machine.
The table values are calculated at the end of the arm without the bucket. In order to find
the allowable loads for machines with bucket, the bucket weight must be subtracted from
the values in the table.
