7.3 Repairs (cont’d)
If for any reason the decision is made to replace parts, please
comply with the following instructions in this manual and
perform all work in the sequence shown.
Production losses are often more expensive than stocking
critical high wear parts. Consider maintaining an inventory of
critical high wear parts.
Any screws, nuts, or bolts removed must be replaced with the
same quality (strength, material) and design.
Before beginning any repair or maintenance work on the
machine or its drives, ensure that it cannot be switched on
accidentally. Set the machine into the “Maintenance Mode”.
See Section 1.7 “Maintenance Mode”
Use original Blastrac replacement parts only.
7.4 Scarifier Drum
The scarifier drum is a highly stressed component of the machine and special
attention should be paid to the drum during maintenance and repairs.
If the scarifier drum is replaced always clean and lubricate the drive shaft so that
the next time the drum is replaced rust or deposits of dirt do not make the
replacement more difficult. Reassemble using Dynatex Anti-Seize PN 49560 or
Loctite Anti-Seize PN 767.
If the scarifier drum must be dismantled for new parts to be installed or
components replaced, make sure that the arrangement of the scarifier cutters
and spacers is maintained as shown in the enclosed components drawings found
in Section 10 “Spare Parts”. In addition, make sure that the holes in the
covering plate for the lateral axles are not worn out and that the screws are tight.
