1SAFE OPERATION
SAFE OPERATION
Careful operation is your best insurance against an
accident.
Read and understand this manual carefully, before
operating the excavator.
Every user, however experienced, should carefully read
and understand this manual and those of the attachments
and accessories before operating the excavator. The
owner is obliged to inform all operators of these
instructions in detail.
Keep this manual in the storage location. (See "Where to
keep Operator's Manual" in "MAINTENANCE" section.)
1. Know your equipment and its limitations. Read and
understand this entire manual before attempting to
start and operate the excavator.
2. Obey the danger, warning and caution labels on the
machine.
3. Track can be set at the narrow width (990 mm) or the
standard width (KX016-4 : 1240 mm, KX018-4 : 1300
mm).
(for details see "OPERATION OF TRACK WIDTH
CHANGES")
To change the track width, set the track width fully,
standard or narrow width.
If not, the excavator may unintentionally move.
4. For your safety, a ROPS/OPG (Roll-Over Protective
Structure, Operator Protective Guards(top guard).)
with a seat belt is installed by KUBOTA. Always use
the seat belt when the machine is equipped with a
ROPS/OPG 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 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 is loosened or removed for any reason,
make sure all parts are reinstalled correctly. Tighten
mounting bolts to proper torque.
5. ROPS/OPG structure complies with ISO 3471, ISO
3449 and OSHA regulations.
6. The seat belt must be inspected regularly and
replaced if frayed or damaged.
7. Always sit in the operator's seat when starting engine
or operating levers or controls.

8. Take precautions against tipping over. Stay away from
steep slopes and embankments. Do not swing the
bucket downhill. Lower the dozer blade when digging.
Keep the bucket as low as possible while driving uphill.
Turn slowly on slopes (at reduced speed). Do not
place the excavator near the edges of trenches and
banks, as the earth can give away due to the weight of
the excavator.
ALLOWABLE CLIMBING ANGLE : 36 % (20 deg.)
ALLOWABLE ANGLE CROSS : 27 % (15 deg.)
9. Watch where you are going at all times.
Watch for and avoid obstacles. Remain alert for trees,
wires and other obstructions.
CSafety 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.
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 not a
safe place for them to ride. Theymay fall off and berun
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.

ALock all control levers.
ARemove the key.
ALock the cab door (if equipped)
3. AFTER OPERATION
(1) Pilot control lock lever (A) "Unlock"
(B) "Locked"

5SAFE OPERATION
1. Observe all regulations concerning the transport of
excavators on public roads.
2. Use adequately long and robust ramps when loading
on the machine. (for details see "TRANSPORTING
THE EXCAVATOR ON A VEHICLE")
3. Do not change the running direction and to avoid
tipping over, do not try to swing the attachment
crosswise to the loading ramps.
4. Lower the attachment onto the transport surface and
release the pressure from the hydraulic system.
Stop the engine then remove the key.
After loading the excavator on a truck, block the tracks
with blocks and tie down the excavator with the chain.
After loading of the excavator on a truck, engage the
swing lock pin.
5. Avoid abrupt braking of the vehicle with the excavator
loaded. Sudden braking cause the excavator to move
and may cause a serious accident.
6. When towing the excavator or pulling a load, the load
must be less than the strength of the towing line
attached to excavator. The towing eye should not be
used for tie down or lifting of the machine.
Before doing maintenance work on the excavator, place
the machine on a firm, flat and level surface, lower the
attachments to the ground, stop the engine, release
pressure trapped in the hydraulic system, lock all control
levers and remove the key. When dismantling hydraulic
parts, make sure that the hydraulic oil has cooled down
sufficiently to avoid burns.
Start maintenance work carefully, e.g. loosen plug 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. Always turn off the engine when filling the fuel tank.
Avoid spilling and over-filling of fuel.
3. 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.
4. Do not use or charge a 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 the directions "STARTING WITH AN
AUXILIARY BATTERY" in "OPERATION OF THE
ENGINE", when starting with an auxiliary battery.
6. Keep a first-aid box and a fire extinguisher at hand at
all times.

5. MAINTENANCE

SAFE OPERATION6
7. 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.
8. To avoid short-circuiting the battery, always remove
the ground cable first and attach the positive cable
first.
9. Oil under high pressure can penetrate the skin and
may be harmful to your health if not treated
immediately.
10.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 that 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.
11.To avoid environmental damage from acid and heavy
metals, dispose of the battery appropriately.
12.Observe all laws and regulations concerning the
disposal of used oil, coolants, solvents, hydraulic
fluids, battery acids and batteries.
13.To avoid fire, do not heat the hydraulic components
(tanks, pipes, hoses, cylinders) before they have been
drained and washed.
14.Use eye protection or a face mask to protect the eyes
and respiratory system against dust and other foreign
particles.
15.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.
16.Do not dismantle the spring of the track tensioner. If
dismantling is necessary, contact your KUBOTA
dealer where the machine was purchased, or
competent service shop. The assembly must be done
according to the KUBOTA work shop manual (W.S.M.)
for the product involved.
17.When lifting the machine itself with an attachment,
place a safety block or safety post to prevent the
machine from rolling over. Keep the lock lever for
attachment control in the "LOCK" position.

7SAFE OPERATION
18.Inspect ROPS / OPG for damage and if damage is
found contact your KUBOTA dealer for repair.
19.KUBOTA does not use asbestos containing
components and recommends against the use of such
components.
