qSafety 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.

NOISE (PC160LC) 1

Two labels indicating the machine noise level are affixed on the machine.

qSound pressure level at the operator’s station, measured

according to ISO6396 (Dynamic test method, simulated

working cycle).

The maximum value of the standard deviation of the meas-

ured time-averaged A-weighted emission sound pressure

level at the operator's position is 2.5 dB, 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 0.27 dB.

Vibration levels for PC160 and PC190-8 1

When used for its intended purpose, levels of vibration for the earth-moving machine transmitted from the opera-

tor’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 uncertainty for this

value is 0.48 m/s² according to EN12096:1997.

The actual acceleration value for the body is less than or equal to 0.5 m/s², the uncertainty for this value is 0.23 m/

s² according to EN12096:1997.

These values were determined using a representative machine and measured during the typical operating condi-

tion indicated below according to the measurement procedures that are defined in the standards ISO 2631/1 and

ISO 5349.
