3.12 Abrasive sealing
The front seal system comprises of three polyurethane seals to ensure
that good fit is maintained between the side seals and the work surface
at the bottom. The seals are located in a seal box at the front of the
blast opening of the cabinet and are clamped into place by bolts and
plates.
To obtain access to front seal system:
1. Connect the machine to the power supply, drive the machine
backwards on the two drive ramps and lift the front side of the
machine until the rear of the blast wheel motor rests on the work
surface.
Important note : to prevent injury lock the front side of
the machine with a wooden block.
2. Unscrew the bolts at the front of the seal box. This releases the
clamp plates holding the seals. Pull worn seals out of the
locating box.
3. Replace worn seals. Fit new seals, each interspaced by a steel
strip as shown below. Retighten the bolts and nuts.
4. Remove the wooden block, lower the front of the machine and
drive the machine from the ramps.
