- The first step in making sure your air assist is set up properly is to
turn off all air controls on the wraps. Release any air pressure you may have
on the cylinders. Now you should set up the wraps to operate perfectly
without any air being used. The brushes should follow the front sides and
back of the car properly. - If the wraps are too heavy on the car, then use the 9/16” bolts to
shift the bottom bearing to the center line, tilting the arms out. (This can be
done by holding up cars for a few minutes and jumping on a ladder then
letting them run to see if it’s better or worse.) If the brush is too light then
do the opposite, slide the bottom bearing out to make brush heavier. A wrap
brush should operate perfectly without any assist / retract. - Once the wraps work properly with natural gravity, meaning not too
much pressure or too little on the car, you can begin to adjust the air on the
assist cylinders. - You should set the air assist regulators to around 25lbs. Now
in the wash controller you’ll want to turn this output on when the brush has
completely come around the front bumper and is near the front quarter
panel.
The independent air assist for each wrap allows you to adjust each one
precisely. You do not want the air assist to turn on until the wrap has come
around the front end naturally. Doing so will make the brush launch out very
fast. Now the air assist should stay on just around the mirror and antenna
area of the car. Then release near the back door / window, and then the
brush should come around the backend of the car under gravity.
