k WARNING
Komatsu recommends that any service parts used for mainte-
nance, repair or replacement of emission control systems be
genuine new Komatsu or Komatsu approved rebuilt parts or
assemblies or others parts of equivalent quality, and that the
engine be serviced by an authorized Komatsu distributor. Fail-
ure to follow these recommendations could result in ineffective

FOREWORD
This manual provides rules and guidelines which will help you use this machine safely and effectively. The pre-
cautions in this manual must be followed at all times when performing operation and maintenance. Most accidents
are caused by the failure to follow fundamental safety rules for the operation and maintenance of machines. Acci-
dents can be prevented by knowing beforehand conditions that may cause a hazard when performing operation
and maintenance.
k WARNING
Before beginning operation or maintenance, operators and maintenance personnel must always observe the fol-
lowing points.
Read this manual thoroughly and understand its contents fully.
qRead the safety messages and safety labels given in this manual carefully so that they should be understood
fully.

SAFETY INFORMATION
SAFETY INFORMATION:ALL-1110-010A00A
To enable you to use the machine safely, safety precautions and labels are given in this manual and affixed to the
machine to give explanations of situations involving potential hazards and of the methods of avoiding
such situations.
Signal Words
The following signal words are used to inform you that there is a potential hazardous situation that may lead to
personal injury or damage.
In this manual and on machine labels, the following signal words are used to express the potential level of hazard.
Example of safety message using signal word
k WARNING
When standing up from the operator’s seat, always place the lock lever in the LOCK position.
If you accidentally touch the control levers when they are not locked, this may cause serious injury or death.
The following signal words are used to alert you to information that must be followed to avoid damage to the
machine.
Indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury.
Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
Indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury. This word is used also to alert against unsafe practices that may cause
property damage
NOTICE This precaution is given where the machine may be damaged or the service life reduced
if the precaution is not followed.

SAFETY LABELS
Safety labels are affixed to the machine to inform the operator or maintenance worker on the spot when carrying
out operation or maintenance of the machine that may involve hazard.
This machine uses “Safety labels using pictograms” to indicate safety procedures.
Safety labels using pictogram
Safety pictograms use a picture to express a level of hazard-
ous condition equivalent to the signal word. These safety picto-
grams use pictures in order to let the operator or maintenance
worker understand the level and type of hazardous condition at
all times. Safety pictograms show the type of hazardous condi-
tion at the top or left side and the method of avoiding the haz-
ardous condition at the bottom or right side. In addition, the
type of hazardous condition is displayed inside a triangle and
the method of avoiding the hazardous condition is shown
inside a circle.
Komatsu cannot predict every circumstance that might involve a potential hazard in operation and maintenance.
Therefore, the safety messages in this manual and on the machine may not include all possible safety precau-
tions.
If any procedures or actions not specifically recommended or allowed in this manual are used, it is your responsi-
bility to take the necessary steps to ensure safety
In no event should you engage in prohibited uses or actions described in this manual.
The explanations, values, and illustrations in this manual were prepared based on the latest information available
at that time. Continuing improvements in the design of this machine can lead to changes in detail which may not
be reflected in this manual
Consult Komatsu or your Komatsu distributor for the latest available information of your machine or for questions
regarding information in this manual.
The numbers in circles in the illustrations correspond to the numbers in () in the text. (For example: -> (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
specifications that are necessary for use in your country. If there is any question about whether your product com-
plies with the applicable standards and regulations of your country, consult Komatsu or your distributor before
operating the machine.

NOISE (PC210-10, PC210LC-10)
Two labels indicating the machine noise level are affixed on the machine.
qSound pressure level at the operator’s station, meas-
ured according to ISO 6396 (Dynamic test method, sim-
ulated working cycle).
The maximum value of the standard deviation of the
measured time-averaged A-weighted emission sound
pressure level at the operator’s position is 2.5dB, in
accordance with ISO 11201.
qSound power level emitted by the machine, measured
according to ISO 6395 (Dynamic test method, simulated
working cycle). This is the guaranteed value as specified in
European directive 2000/14/EC.
This value includes an uncertainty of 1.0 dB.

VIBRATION LEVELS
qWhen used for its intended purpose, levels of vibration for the earth-moving machine transmitted from the
operator’s seat are lower than or equal to the tested vibrations for the relative machinery class in compliance
with ISO 7096
qFor PC210-10, PC210LC-10
qThe actual acceleration value for the hands and arms is less than or equal to 2.5 m/s², the uncertainty for this
value is 0.53 m/s² according to EN12096:1997.
qThe actual acceleration value for the body is less than or equal to 0.5 m/s², the uncertainty for this value is
0.28 m/s² according to EN12096:1997.
qThese values were determined using a representative machine and measured during the typical operating
condition indicated below according to the measurement procedures that are defined in the standards ISO
2631/1 and ISO 5349.
qOperating condition:
qExcavating (Digging-loading-rotating-unloading-rotating)
qGuide to Reduce Vibration Levels on Machine
qThe following guides can help an operator of this machine to reduce the whole body vibration levels:
qUse the correct equipment and attachments.
qMaintain the machine according to this manual
qTension of crawler (for crawler machines)
qBrake and steering systems
qControls, hydraulic system and linkages
qKeep the terrain where the machine is working and travelling 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 condi-
tions
qUse 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
qSteer, brake, accelerate, and move the attachment levers and pedals slowly so that the machine moves
smoothly
qAdjust 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 travelling path as large as possible
qTravel at low speed when travelling around sharp curves
qMinimize vibrations for long work cycle or long distance travelling
qReduce speed to prevent bounce
qTransport machines long distances between worksites
qThe 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
