8. Techn cal data
The electrical diagrams of the electrical system are placed inside of the control panel.
Design and specifications are subject to change ithout notice by Blastrac.
IMPORTANT NOTE:
The indicated values are measured on ne machines. Sound and vibration levels ill vary in different
circumstances. Area influences like open outside or closed inside space, ambient temperature, the surface to
be treated, etc. ill give different values at all time.
The declared vibration and sound emission levels represent the main applications of the machine. Ho ever if
the machine is used ith 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 hich the
machine is s itched off or even running, but not actually in use. This may significantly decrease the exposure
level over the total orking period. Ear protection is recommended ith the use of this equipment.
