Wear Parts
8.1 Wear Parts
Certain portions of the blast unit are continuously exposed to high velocity abrasive.
These areas and their corresponding parts must be periodically inspected for wear and
erosion to keep from damaging components that are not normally exposed to the
abrasive blast. These parts are identified on the service drawings later in this manual
along with part numbers. Maintenance personnel design all parts for relatively easy
replacement. A preventive maintenance program should be performed to monitor these
areas on a regular basis. The following list outlines these areas and the time intervals
involved.

Keep in mind that other portions of the machine require periodic inspections and
maintenance. The parts mentioned above are associated with the internal abrasive
blast. Electrical cable and exhaust hose, for example, also require close inspection and
maintenance.
