Check the magnetic seals on the bottom of the blast unit for metallic
contaminants such as nuts, bolts, etc. remove any foreign objects. Push the blast
unit forward at a normal working pace. Deposit a layer of abrasive on the floor in
front of the magnets. Drive the machine over the abrasive to charge the magnets
with a layer of abrasive. The abrasive will form a seal between the magnets and
the floor. Remove any excess abrasive from the floor.

4.2 Blast Cleaning
1. Start walking forward and ease the shot valve open by pulling up on the shot valve
handle.
Caution: Never operate the shot valve if the machine is not moving;
this could dig a hole in the concrete floor resulting in timely repairs.
2. After cleaning a five-foot test strip, close the abrasive valve, stop the machine and
check the cleaned area. The texture should be even across the 8 inch path.
3. If the brightness or texture of the test strip is uneven, refer to Section 5, “Blast
Pattern”, to adjust the “HOT SPOT”.
4. If the cleaning is too severe or inadequate, adjust your travel speed accordingly. A
faster pace will result in a lighter surface profile while a slower pace will be more
aggressive and result in a deeper profile. If irregular surfaces are encountered,
adjust your speed accordingly (see Section 7 - “Equipment Calibration”).
