4.6 Wear Brush
Assembly Adjustment
The wear brush bristles will slowly wear during
operation. Consequently, the wear brush will re-
quire adjustment periodically to keep the bristles
in contact with the pavement to provide proper
vacuum air flow. It will also need to be adjusted
when the standoff distance is increased or when
the shroud and/or wear brush is replaced.
Use the following procedure to adjust the
wear brush assembly:
1. Make sure the truck is in WORK mode and
lower the hog head onto a level surface.
2. Turn on the FLOAT switch to be sure the heads
are flat with the surface.
3. Shutdown the waterblasting system and place
the truck in service position.
4. Note the gap between the bottom of the brush
and the surface.
5. Loosen the brush clamp on the blast head.
6. Tap the brush down evenly using a dead blow
hammer until the bristles are just touching the
surface and the gap is eliminated.
7. Make sure the brush bristles are not pressed
hard against the pavement. If the brush is
set too tight against the surface, it will cause
premature wear to the bristles resulting in
reduced vacuum air flow and accelerated
brush wear.
8.
Tighten the clamp and recheck. Readjust if
necessary.
