712MT OPERATOR’S MANUAL                            11/19/12                                            Page 12 of 16 

     OPERATOR PREPARATION (continued) 

 
 
 

 
Wear safety eye goggles and a hard hat while operating or observing!  

WARNING

: The dig chain may throw stones and debris.   

 

Wear safety boots and gloves. Wear close-fitting clothing. Contain long 
hair. Do not wear jewelry. Wear reflective clothing if working near 
traffic.   

 

Wear adequate hearing (ear) protection while operating or observing. 

WARNING

: Exposure to loud noise is cumulative and may 

permanently damage your hearing.   

 
 

Declared vibration emission value in accordance with EN 12096: the 
average measured vibration emission value is 5.5 m/s

2

. The uncertainty 

in the measurement given a 95% confidence interval is 1.1 m/s

2

. Safety 

gloves help to isolate the hands from the vibration, keep them warm and 
dry, maintain blood circulation, and make operators less susceptible to vibration induced injury. 

 

Hearing protection devices do not all provide the same level of protection. Those that completely surround each ear are 
better than earplugs. It is important to select a device that is adequate and appropriate for your specific work 
environment since the peak noise level varies. A local environmental noise specialist may help you to determine the 
level of hearing protection required.  
 
 

 

DECLARED  DUAL-NUMBER  NOISE EMISSION  VALUES

 

in accordance with ISO 4871

 

 

Measured A-weighted sound power level, 
LWA  (ref. 1pW) in decibels 
Uncertainty, KWA, in decibels 
Measured A-weighted sound pressure level, LpA  
(ref. 20µPa) at the operator's position in decibels 
Uncertaint  K A  in decibels

 

Operating Mode 1

 

 

92.1 

3.0 

 

88.6 

3 0

 

Values determined according to noise test code given in Directive 2000/14/EC Annex 
IIIB part 54 using the basic standard ISO 3744: 1994 

 

NOTE - The sum of a measured noise emission value and its associated uncertainty represents an 
upper boundary of the range of values which is likely to occur in measurements.
