Noise emission and vibration
The values specified in these operating instructions were identified during the test cycle on an identical machine
and are valid for a machine with the standard equipment. The determined values are specified in the Technical
Data (page 39).
Noise emission
The noise levels were determined using the method for determining the guaranteed sound pressure level of
ISO 4871 based on directive 2000/14/EC, Appendix VI.
The noise levels indicated are not applicable for the determination of additional workplace noise emissions. The
ctual noise levels may need to be determined directly at the workplaces, subject to actually existing conditions
a
(other noise sources, special operating conditions, sound reflections).
Depending on the actual noise emissions, the owner must provide the operator with the necessary personal protective equipment (ear protection).
Noises at a noise level of more than 85 dB (A) can cause hearing damage.
At a noise level of 80 dB (A) and up, the use of ear protection is recommended.
At a noise level of 85 dB (A) and up, the operator must wear ear protection.
Vibrations
The vibrations on the machine have been determined using an identical machine.
The vibration stress on the operator over a longer period of time must be determined by the owner at the operating
ite, in compliance with directive 2002/44/ EC in order to consider individual magnitudes of influence.

Fire protection
The excavator components and attachments (in particular the engine and the exhaust system) reach
high temperatures even under normal working conditions. An electric installation that is damaged or
not properly serviced may lead to flashovers and/or electric arcs. The following fire protection guidelines may help you ensure the maintenance and efficiency of your equipment and minimise fire hazards.
Remove any accumulated dirt adjacent to hot components, e.g. engine, muffler, exhaust manifold/tubes, etc.
If the machine is being used at full capacity, cleaning should be performed more frequently.
Accumulated residues from plants and trees, or any other flammable materials, should be removed from the
machine. This must be observed in particular in the proximity of the engine and the exhaust system, but also
in the swivel frame, the track frame, and the boom.
Check the condition and wear of all fuel lines and hydraulic hoses. Any defective parts should be replaced
immediately in order to avoid leaks.
Electric cables and connections must be checked regularly for signs of damage. Damaged components and
lines must be replaced or repaired before starting up the machine. All electric connections must be kept clean
and tight.
Exhaust pipes and mufflers must be checked daily for leaks, damage and any loose or missing joints. Leaking
or damaged exhaust system components must be replaced or repaired before starting up the machine.
Always keep a multi-purpose fire extinguisher on or close to the machine. Familiarise yourself with the oper-
ation of the fire extinguisher. In the event of a fire in the electrical or hydraulic system, use a CO
fire extin-
2
guisher to put it out.

Recovery, loading and transport
RECOVERY, LOADING AND TRANSPORT
Safety rules for recovery
For recovery of the excavator, a towing vehicle of at least the same weight class as the excavator must be
used.
A tow bar must be used for the recovery. If a tow rope is used, an additional vehicle must also be attached to
brake the excavator. The tow bar or tow rope must be suitable for the recovery of the excavator with regard
to the towed load. Do not use damaged recovery aids.
Do not step into the danger zone between the vehicles during the recovery procedure. If a tow rope is used,
keep a distance of at least 1.5 times the length of the rope.
Use the towing eye on the track frame for the recovery.
The above safety rules also apply if the excavator is used as the towing or recovery vehicle.
Observe the admissible values for the towed load and the vertical load during recovery, see "Technical data"
(page 39).
Safety rules while loading with a crane
Crane and lifting gear must be suited for carrying the load to be lifted and be approved.
Before using the crane and the lifting gear, make sure that the specified safety inspections have been carried
out regularly and that the crane and lifting gear are in good working order and sound condition.
The excavator may only be lifted at the provided attachment points. Do not attach the lifting gear to the cab
roof as this can lead to substantial damage.
Never attach a crane hook to the lower edge of the dozer! The crane hook can slip off sideways while lifting
and the excavator may fall off.
Always adhere to the valid safety regulations for the lifting of loads.
The excavator must be secured with a holding rope when it is being lifted.
The crane operator is responsible for the observance of these safety rules.

OPERATION
Safety rules for operation
The safety instructions (page 13) must be followed.
The excavator may only be operated in accordance with the “Approved use” section (page 15).
The machine may only be operated by instructed or trained personnel (page 10).
Do not operate the excavator when under the influence of drugs, medication or alcohol. Stop operation when
getting tired. The operator must be physically capable of operating the excavator safely.
The excavator should only be operated if all protective devices are fully operational.
Before starting or working with the excavator, make sure that there is no danger for any person nearby.
Before starting the excavator, it must be checked for external damage and operability, and the pre-start
checks must be carried out. If defects are detected, the excavator should only be taken into operation after
the defects have been repaired.
Wear tight-fitting working clothes in accordance with the trade association regulations.
During the operation of the excavator, nobody except the operator is allowed to be inside the cab or get on
the excavator.
For getting on and off, the swivel frame should be positioned in an angle that allows the operator to use the
crawler or the step (if applicable) to enter the cab.
Always stop the engine when leaving the cab. In exceptional cases, e.g. for troubleshooting, the cab can also
be left with the engine running. The operator must make sure that the left control console remains in an upright
position. The controls may only be used while the operator is sitting on the operator's seat.
During operation, it is forbidden to stretch any part of the body out of the window or cab door, such as arms,
legs, or the body.
If the operator leaves the excavator (e.g. for breaks or at the end of work), the engine must be stopped and
the excavator must be secured against restarting by removing the key. The cab door must be locked. Before
leaving the excavator, park the machine so that it cannot move.
Whenever work is interrupted, the bucket must always be lowered to the ground.
Do not allow the engine to run indoors, unless the room is equipped with an exhaust gas extraction system
or otherwise well ventilated. The exhaust gas contains carbon monoxide, a colourless, odourless, and lethal
gas.
Never crawl under the excavator before the engine is stopped, the key is removed and the excavator is se-
cured against moving.
Never crawl under the excavator if it is only raised with the bucket or the dozer. Always use suitable supports.
To increase the machine’s stability, we recommend lowering the bulldozer blade onto the ground. The dozer
may only be used if the dozer cylinder is equipped with a pipe safety valve.

Safety for children
Children are normally attracted to machines and their operation. If children are in the vicinity of the
mac
hine and are not at a suitable distance and in the field of vision of the operator, this can lead to
serious accidents or even death of the children.
Always observe the following rules of conduct:
Never assume that children will remain where you last saw them.
Keep children far away from the working area and always under the supervision of other responsible adults.
Be vigilant and switch the machine off when children enter the working area.
Never let children drive with you on your machine, there is no safe place for passengers. Children could fall
off the machine and be run over or affect the control of the machine.
Children must never operate the machine, even under the supervision of an adult.
Never let children play on the machine or attachments.
Be particularly careful when manoeuvring. Look behind and down below on the machine and ensure that there
are no children in the manoeuvring area.
Before leaving the machine, park it so that it cannot move. When leaving the machine (e.g. for breaks or at
the end of work), stop the engine, remove the key and close the cab door, if present.
Guiding the operator
If the operator's working and driving area is obscured, the operator must be supported by a guide.
The guide must be capable of performing this kind of work.
Before starting work, the guide and the operator must agree on the necessary signals.
The guide's position must be clearly visible to the operator.
The operator must stop the excavator immediately if eye contact with the guide is interrupted.
s a rule, either the excavator or the guide may move, never both at once!

Operation
Working in the vicinity of overhead power lines
When working with the excavator in the vicinity of overhead power lines and tram lines, a minimum distance as
specified in the following table must be maintained between the excavator and its attachments and the power line.
Rated voltage [V] Safe distance [m]
up to 1 kV 1.0 m
over 1 kV up to 110 kV 3.0 m
over 110 kV up to 220 kV 4.0 m
over 220 kV up to 380 kV or when rated voltage is unknown 5.0 m
If safe distances cannot be maintained, the power lines must be switched off in coordination with their owner or
rovider and secured against turning on again.
p
When approaching overhead power lines, any possible movements of the excavator must be taken into consideration.
Unevenness of the ground or sloping the excavator can reduce the safe distance.
Wind can cause the overhead power lines to sway, thus reducing the safe distance.
In case of a power cross-over, leave the danger zone with the excavator, if possible, by taking suitable measures.
this is not possible, do not leave the operator's place, warn any approaching persons of the danger, and have
If
the power switched off.
Working in the vicinity of underground power lines
Before starting with excavation work, the owner of the excavator or the person responsible for the work must check
if there are any underground power lines in the proposed working area.
If there are underground power lines present, the position and routing of the power lines must be determined together with the owners or operators and the required safety measures must be determined.
If power lines are encountered or accidentally damaged, the operator must stop working immediately and inform
e responsible person.
th
Initial operation
Before initial operation, the excavator must first be checked visually for external transit damages and checked if
the shipped equipment is complete as ordered.
Check fluid levels as described in the "Maintenance" section (page 135).
For a description of all operating features, refer to the "Operating the excavator" section (page 77) as well as
the following sections.

Operation
Running in the excavator
During the first 50 hours of operation, the following points should be adhered to in all cases:
Warm up the excavator at an average engine speed and with a low load; do not let it warm up at idling position.
Do not overload the excavator.
Special maintenance instructions
Damage to equipment due to contaminated grease!
The grease plays a particular and important role in the running-in of the excavator. The movable components are not yet broken in and generate many fine particles in the initial hours of operation that
op into the grease. Changing the oil in due time removes the abraded metal particles, prevents
dr
damage to equipment and preserves the service life of the components.
- Observe and adhere to oil change intervals!
Change the oil in the final drives after the first 50 service hours.
The hydraulic system's return filter should be changed after the first 250 service hours.
Pre-operational services
For the performance of the services, the excavator must be parked on level ground. The engine must
turned off. The left control console must be raised.
be
Open the engine compartment cover (page 144). Close engine compartment cover after completion of the ac-
tivities.
Open the side cover (page 144). Always close the side cover after the work is done.

Notes for rubber crawler operation
Driving or turning on sharp objects or over steps causes exces-
sive wear on the rubber crawlers and will lead to breaking of the
ubber crawler or cause the crawler running surface and the
r
steel inserts to be cut.
Make sure that no foreign objects get stuck in the rubber crawl-
er. Foreign objects lead to excessive crawler wear and can
use it to break.
ca
The crawler can become blocked due to too much dirt and sand. In this case, reverse the machine a short
distance in order to loosen dirt and sand.
Keep oil products away from the rubber crawlers.
Remove any fuel or hydraulic oil spilled on the rubber crawlers.
Making sharp turns
Do not make sharp turns on streets with a high-friction tarmac, e.g. concrete.
Protecting the crawler against salt
Do not work with the machine on the seashore. (The salt will cause the steel insert to corrode.)

Operating the controls during excavation work
Always observe the following safety instructions when working with the excavator.
Breaking concrete or rocks with the bucket is prohibited.
Do not use the dropping action of the bucket for excavation.
Never fully extend the cylinders. Always keep a certain safety margin, especially when operating with a break-
er (accessory).
Never use the bucket as a hammer to drive posts into the ground.
Do not drive or dig with the bucket teeth rammed into the ground.
When loading soil, do not dig the bucket deeply into the ground. Instead, make relatively shallow slices with
the bucket out as far as possible. This technique reduces the stress on the bucket.
When working in water, the water should only reach up to the lower edge of the swivel frame.
After using the machine in water, always grease the pins on the bucket and arm with grease until the old lu-
bricating grease emerges.
When digging in reverse, make sure that the boom does not come into contact with the dozer.
Adhering soil can be shaken off when the bucket is being emptied by moving the cylinder to the end of the
stroke. Should this not suffice, dump the arm as far as possible and swing the bucket back and forth.
To increase the machine’s stability, we recommend lowering the bulldozer blade onto the ground. The dozer
may only be used if the dozer cylinder is equipped with a pipe safety valve.
Note on using wider and deeper buckets
When using a wider or deeper bucket, take good care

Operating the boom
If the excavator is overloaded, the boom must be lowered until the load rests on the ground. To prevent personal
injuries and damage to equipment, do not operate any other functions (e.g. moving the swivel frame).
To raise the boom, pull the right control lever back (figure/ ).
The hydraulic cylinder of the boom is equipped with a
c
ushioning function, which prevents the excavated
material in the bucket from falling out. When the hydraulic system operating temperature is low, the cushioning is delayed by approx. 3 to 5 s. This delay is due
viscosity of the hydraulic oil and is not a mal-
to the
function.
To lower the boom, push the right control lever forward
(figure/ ).
Watch the boom during lowering, so that the boom or
bucket teeth do not hit the dozer.

The auxiliary port serves for operating attachments.
Only attachments approved by KUBOTA may be used. The attachments must be operated in accordance with the operating instructions supplied with them.
When using a breaker or other attachment for demolition work where material (e.g. asphalt) is removed and can uncontrollably sputter away, personal protective equipment is to be worn at all times
safety shoes, safety helmet, eye protection, ear protection and, if necessary, a breathing mask). The
(
use of a gravel guard (front protective grid) is recommended. For excavation work with a cab, the
front window must be closed, in addition.
The performance data for the auxiliary port can be found in the "Technical data" section (page 39).
Make sure that, before carrying out the activities in the auxiliary port connectors, the hydraulic system
(page 104) has been depressurised. Depending on the operation setting, the return change valve
has to be set to the appropriate position (page 103).
Operation
The auxiliary ports may only be activated when an implement is attached.
If the auxiliary port has not been used for a long period of time, dirt particles could have accumulated
connectors of the conduits. Before installing the attachment, drain approx. 0.1 L of hydraulic
on the
oil at each port.
Collect the drained hydraulic oil in a container and discard it in accordance with the valid environmental regulations.
Models KX027-4 and KX030-4 are equipped with a hydraulic auxiliary port. An auxiliary port connector (1) is located on both the left
d right side of the arm. The auxiliary port function is controlled
an
