Foreword 1.2 Safety information PW180-7E0 – VEAM400102 1-3 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 procedures 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 1-4 PW180-7E0 – VEAM400102 1.3 Noise emission levels Two labels indicating the machine noise level are affixed on the machine. Sound pressure level at the operator’s station, measured according to ISO6396 (Dynamic test method, simulated working cycle). 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 conditions 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 loading; 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 possible Travel at low speed when traveling around sharp curves 7. Minimize vibrations for long work cycle or long distance traveling 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 accumulators 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.

1.7 Introduction Foreword 1-8 PW180-7E0 – VEAM400102 1.7 Introduction 1.7.1 Intended use This KOMATSU HYDRAULIC EXCAVATOR is designed to be used mainly for the following work: Digging Smoothing work Ditching work Loading work See the section "Work possible using hydraulic excavator (3-141)" for further details. 1.7.2 Features This KOMATSU HYDRAULIC EXCAVATOR is equipped with various controls based on an advanced electronics system.
