Ø75 mm Ø75 mm Ø75 mm Design and specifications are subject to change without notice by Blastrac BV IMPORTANT NOTES: Noise and vibration measurements were taken during heavy operation on concrete. The noise and vibration levels depend on the working depth, which is in turn determined by the unevenness of the surface. The impact force of the tools onto the surface is the biggest factor in both noise and vibration levels. - Page 41 Despite the fact that this guide is made with care, Blastrac takes no liability for errors in the manual and the possible consequences. We are naturally very interested in your findings and additions. No part of this publication may be reproduced...
