Design and specifications are subject to change without notice by Blastrac BV
IMPORTANT NOTE:
The indicated values are measured on new machines. Sound and vibration levels will vary in different
circumstances. Area influences like open outside or closed inside space, ambient temperature, the surface to
be treated, etc. will give different values at all time.
The declared vibration and sound emission levels represent the main applications of the machine. However if
the machine is used with different accessories or poor maintenance, the vibration and sound emissions may
differ. The values may be used for a preliminary assessment of exposure.
For a precise estimate of the vibration and sound load, the times should also be considered during which the
machine is switched off or even running, but not actually in use. This may significantly decrease the exposure
level over the total working period. Ear protection is recommended with the use of this equipment.
