7.4 Scarifier Drum (cont’d)
To obtain an even, clean surface profile on the surface to be scarified:
• Ensure that the correct scarifying depth is set.
• Ensure that the machine is being driven at the correct drive speed.
• Ensure that the correct components for the scarifier drum are being used.
• Ensure that the correct scarifier cutters for that specific surface are being
used.
Incorrectly installed scarifier drum will cause unbalanced
machine operation and excessive wear.
Incorrect assembly of OEM machine parts and components voids the
equipment warranty.
Use of non-OEM parts and cutters voids the equipment warranty.
7.5 Equipment for the Scarifier Drum
The examples of scarifier cutters enclosed within this manual have been
extensively tested by Blastrac technicians and display an even scarified pattern.
The selection of cutter types and the component arrangement are among the
most important factors for proper operation and efficiency of these machines.
An incorrect component arrangement for the scarifier drum
leads to extreme wear rates and reduces machine performance.
See Section 10 “Spare Part” for component mounting
diagrams.
