This manual provides rules and guidelines which will help you use this machine safely and effectively.  The precautions 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.  Accidents can be prevented by knowing beforehand conditions that may cause a hazard when performing operation and maintenance.

Before beginning operation or maintenance, operators and maintenance personnel must always observe the following points.
Read this manual thoroughly and understand its contents fully.
Read the safety messages and safety labels given in this manual carefully so that they should be understood fully.
Keep this manual at the storage location for the Operation and Maintenance Manual given below so that all personnel involved in working on the machine can consult it periodically.
In case this manual should be lost or damaged, immediately contact Komatsu or your Komatsu distributor to obtain a new copy.
When you sell the machine, make sure that this manual should be provided to the new owner together with the machine.
In this manual, measurements are expressed in international standard units (SI). For the reference purpose, weight units used in the past are also displayed in ( ).

To enable you to use this 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.

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.

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 a serious injury or death.

Other signal words
In addition to the above, the following signal words are used to indicate precautions that should be followed to protect the machine or to give information that is useful to know. This word is used for precautions that must be taken to avoid actions which could shorten the life of the machine. This word is used for information that is useful to know.

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 words“ and “Safety labels using pictograms“ to indicate safety procedures.

Safety labels using pictogram
Safety pictograms use a picture to express a level of hazardous condition equivalent to the signal word.  These safety pic-tograms 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 condition at the top or left side, and the method of avoiding the hazardous 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 precautions.

If any procedures or actions not specifically recommended or allowed in this manual are used, it is your responsibility 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.

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.

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.
