1.2 Safety information
1.2.1 Safety messages
Most accidents are caused by the failure to follow fundamental
safety rules for the operation and maintenance of machines.
To avoid accidents, read, understand and follow all precautions
and warnings in this manual and on the machine before perform-
ing operation and maintenance.
To identify hazards on the machine pictorial decals are used,
see "Position for attaching safety labels (2-36)".
Red warning triangle
This is used on safety labels where there is a high probability of
serious injury or death if the hazard is not avoided. These safety
messages or labels usually describe precautions that must be
taken to avoid the hazard. Failure to avoid this hazard may also
result in serious damage to the machine.
Orange warning triangle
This is used on safety labels where there is a potentially danger-
ous situation which could result in serious injury or death if the
hazard is not avoided. These safety messages or labels usually
describe precautions that must be taken to avoid the hazard.
Failure to avoid this hazard may also result in serious damage of
the machine
Yellow safety triangle
This is used on safety labels for hazards which could result in
minor or moderate injury if the hazard is not avoided. This word
might also be used for a hazard where the only result could be
damage to the machine.
NOTE
This word is used for precautions that must be taken to avoid
actions which could shorten the life of the machine.
Safety precautions are described in "Safety (2-1)".
KOMATSU cannot predict every circumstance that might involve
a potential hazard in operation and maintenance. Therefore the
safety message in this manual and on the machine may not
include all possible safety precautions. If any procedures or
actions not specifically recommended or allowed in this manual
are used, you must be sure that you and others can do such pro-
cedures and actions safely and without damaging the machine.
If you are unsure about the safety of some procedures, contact
KOMATSU or your KOMATSU distributor.

1.3 Noise emission levels Foreword

1.3 Noise emission levels
Two labels indicating the machine noise level are affixed on the
machine.
z Sound pressure level at the operator’s station, measured
according to ISO6396 (Dynamic test method, simulated
working cycle).
z Sound 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.

Foreword 1.4 Vibration levels
PW180-7E0 – VEAM400102 1-5
1.4 Vibration levels
When 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.
The actual acceleration value for the hands and arms is less
than or equal to 2.5 m/s². The actual acceleration value for the
body is less than or equal to 0.5 m/s².
These 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.
Operating condition:
Excavating (Digging-loading-rotating-unloading-rotating)
1.4.1 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
 Tire pressures (for wheeled machines), tension of
crawler (for crawler machines)
 Brake and steering systems
 Controls, hydraulic system and linkages
3. Keep the terrain where the machine is working and traveling
in good condition
 Remove any large rocks or obstacles
 Fill any ditches and holes
 Site manager should provide machine operators with
machine and schedule time to maintain terrain condi-
tions
4. Use a seat that meets ISO 7096 and keep the seat main-
tained and adjusted
 Adjust the seat and suspension for the weight and size
of the operator
 Wear seat belt
 Inspect and maintain the seat suspension and adjust-
ment mechanisms

1.4 Vibration levels Foreword
1-6 PW180-7E0 – VEAM400102
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
 When pushing with bucket or blade, avoid sudden load-
ing; load gradually
 Drive around obstacles and rough terrain conditions
 Slow down when it is necessary to go over rough terrain
 Make the curve radius of traveling path as large as pos-
sible
 Travel at low speed when traveling around sharp curves
7. Minimize vibrations for long work cycle or long distance trav-
eling
 Reduce speed to prevent bounce
 Transport machines long distances between worksites
8. The following guidelines can be effective to minimize risks of
low back pain
 Operate the machine only when you are in good health.
 Provide breaks to reduce long periods of sitting in the
same posture
 Do not jump down from the cab or machine
 Do not repeatedly handle and lift loads

Foreword 1.5 Emergency steering
PW180-7E0 – VEAM400102 1-7
1.5 Emergency steering
This machine is equipped with an emergency steering system
and complies to ISO 5010 (BSEN 12643). In the event of failure
of the source of power for the steering system (engine failure)
whilst travelling, the machine can be steered allowing the
machine to be safely stopped.
In such a case, the effort required at the steering wheel and the
number of turns to steer the machine will increase. To confirm
function of emergency steering system, raise the front wheels off
the ground (using the work equipment) and with the engine off,
turn the steering wheel and check movement of the wheels.
1.6 Emergency braking
This machine is equipped with an emergency braking system
and complies to ISO 3450. In the event of failure of the source of
power for the braking system (engine failure) whilst travelling,
the brakes can be actuated from stored energy in the accumula-
tors to bring the machine safely to a stop.
In such a case, five brake applications can be made before
exhausting the energy in the accumulators. In the event of ser-
vice brake failure, the park brake can be used as an emergency
brake to bring the machine to a stop.
