Always keep this Operation and Maintenance Manual in the
location shown on the right so that all relevant personnel can
read it at any time.
Storage location for the Operation and Maintenance Manual:
magazine box on the left side of the operator's seat.
If this manual is lost or damaged, contact your distributor immediately to arrange for its replacement. For details
regarding the machine serial No. you will need to provide your Komatsu distributor, see “YOUR MACHINE SERIAL
NUMBERS AND DISTRIBUTOR (1-11)“.
This manual uses the international units (SI) for units of measurement. For reference, units that have been used in
the past are given in ( ).
The explanations, values, and illustrations in this manual have been prepared based on the latest information
available as of the date of its publication. Continuing improvements in the design of this machine may lead to addi-
tional changes that are not reflected in this manual. Consult Komatsu or your Komatsu distributor for the latest
available information concerning your machine or with questions regarding information contained in this manual.
qThe numbers in circles in the illustrations correspond to the numbers in ( ) in the text.
(For example:1→(1))
Komatsu delivers machines that comply with all applicable regulations and standards of the country to which it has
been shipped. If this machine has been purchased in another country, it may lack certain safety devices and spec-
ifications that are necessary for use in your country. If there is any question about whether your product complies
with the applicable standards and regulations of your country, consult Komatsu or your Komatsu distributor before
operating the machine.

SAFETY INFORMATION 1
To enable you to use the machine safely, and to prevent injury to operators, service personnel or bystanders, the
precautions and warnings included in this manual and the safety signs attached to the machine must always be
followed.
To identify important safety messages in the manual and on the machine labels, the following signal words are
used.
The “Safety Alert Symbol“ identifies important safety messages on machines, in manuals, and elsewhere. When
you see this symbol, be alert to the risk of personal injury or death. Follow the instructions in the safety message.
The following signal words are used to alert you to information that must be followed to avoid damage to the
machine.
This signal word indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury.
This signal word indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
This signal word indicates a potentially hazardous situation exists which, if not
avoided, may result in minor or moderate injury
NOTICE This precaution is given where the machine may be damaged or the service life reduced if
the precaution is not followed.
REMARKS This word is used for information that is useful to know.

Noise emission levels 1
One labels indicating the machine noise level is affixed on the machine.
qSound pressure level at the operator's station, measured
according to ISO6396 (Dynamic test method, simulated
working cycle)
The maximum value of the standard deviation of the meas-
ured time-averaged A-weighted emission sound pressure
level at the operator's position is 2.5 dB, in accordance with
ISO 11201
Vibration levels 1
When used for its intended purpose, levels of vibration for the earth-moving machine transmitted from the opera-
tor’s seat are lower than or equal to the tested vibrations for the relative machinery class in compliance with ISO
7096.
The actual acceleration value for the hands and arms is less than or equal to 2.5 m/s², the uncertainty for this
value is 0.22 m/s² according to EN12096:1997.
The actual acceleration value for the body is less than or equal to 0.5 m/s², the uncertainty for this value is 0.17 m/
s² according to EN12096:1997.
These values were determined using a representative machine and measured during the typical operating condi-
tion indicated below according to the measurement procedures that are defined in the standards ISO 2631/1 and
ISO 5349.

Guide to Reduce Vibration Levels on Machine
The following guides can help an operator of this machine to reduce the whole body vibration levels:
1. Use the correct equipment and attachments.
2. Maintain the machine according to this manual
qTire pressures (for wheeled machines), tension of crawler (for crawler machines)
qBrake and steering systems
qControls, hydraulic system and linkages
3. Keep the terrain where the machine is working and traveling in good condition
qRemove any large rocks or obstacles
qFill any ditches and holes
qSite manager should provide machine operators with machine and schedule time to maintain terrain con-
ditions
4. Use a seat that meets ISO 7096 and keep the seat maintained and adjusted
qAdjust the seat and suspension for the weight and size of the operator
qWear seat belt
qInspect and maintain the seat suspension and adjustment mechanisms
5. Steer, brake, accelerate, shift gears (for wheeled machines), and move the attachment levers and pedals
slowly so that the machine moves smoothly
6. Adjust the machine speed and travel path to minimize the vibration level
qWhen pushing with bucket or blade, avoid sudden loading; load gradually
qDrive around obstacles and rough terrain conditions
qSlow down when it is necessary to go over rough terrain
qMake the curve radius of traveling path as large as possible
qTravel at low speed when traveling around sharp curves
7. Minimize vibrations for long work cycle or long distance traveling
qReduce speed to prevent bounce
qTransport machines long distances between worksites
8. The following guidelines can be effective to minimize risks of low back pain
qOperate the machine only when you are in good health.
qProvide breaks to reduce long periods of sitting in the same posture
qDo not jump down from the cab or machine
qDo not repeatedly handle and lift loads.
