7.1 CHANGING TO THE EDGING MODE
This section refers to Figure 7.1.1 on page 40.
The model 1-8DEZ is capable of cleaning surfaces within 1/2 inch of vertical
obstructions. (This is along the side of the machine. The 1-8DEZ can be pushed
as close as 1-1/2 inches from the front of the machine.) Performing the following
steps sets up the edging mode:
1.
Put the 1-8DEZ in “Maintenance Mode” as described in Section 2.3.
2. Remove the two hex screws holding the retainer, seal and magnet on the side
of the machine where the edging is required. This requires a 3/16” hex key.
Be careful to keep abrasive from entering the holes in which the screws were
secured. You may want to cover these two holes with duct tape while in the
edging mode to protect the threads.
3. Move the machine to the area in which the edging will be done and see if the
machine can be moved freely. Adjust the height of the machine if necessary.
4. Begin cleaning in the normal fashion. Do not blast when the machine is away
from the vertical surface in the edging mode since the magnetic seal is no
longer present. Abrasive will disperse more readily from the side if the magnet
is not in place. Keep in mind that the machine will tend to lose more abrasive
while in the edging mode since the magnetic seal has been removed.
WARNING: Do not use the machine for normal blasting
when it was been prepared for edging. The magnet, seal,
and retainer must be reinstalled first. Close the abrasive
valve before moving the 1-8DEZ away from the vertical
surface. Failure to do so may expose nearby personnel
to high velocity abrasive
.
