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.

For details of safety labels, see "SAFETY LABELS (2-3)".

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 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.

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
