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. The parts are identified on the service drawings later in this manual
along with part numbers. These ‘wear” parts are designed to be easily replaced by the
machine operator when necessary. 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.
WARNING: THE 1-8DEZ MUST BE PLACED IN MAINTENANCE MODE (SEE
SECTION 1.2) PRIOR TO CARRYING OUT ANY INSPECTION OR PART

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. The power cords and exhaust hose, for example, also require close inspection
and maintenance as described in other sections of this manual.
If the power cord(s) are found to have splits or cuts, they must be repaired in a manner
that brings them to a same condition, function and safety, as that of a new cord(s). If
this is impossible, they must be replaced.
