ADJUSTMENTS AND TESTING
Adjust the Cleaning Pressure of the Top Brush
•
Ensure the air solenoid is manually put in the wash position so there is no air pressure
applied to the retract cylinder.
•
Adjust the position of the counterweight so that when the counterweight is released the
brush slowly moves downward.
•
After initial adjustment manually activate and deactivate the air retract. When deactivated
the brush should fall smoothly to the down position.
•
Final adjustment of the counterweight can be accomplished while running test vehicles.
•
Once adjusted properly the
cloth penetration should be about 3-
4”
across the entire
vehicle.
Note
: If brush bounces too much, the counterweight has been adjusted too far out.
Adjustment is easiest if made in small amounts, approximately ¼” to ½” at a time.
Adjust Top Brush for Smooth Retract Operation
•
To adjust the retract operation, the
air pressure regulator
should be adjusted for
approximately
30PSI
in the
retract position
.
•
The tunnel controller should be adjusted so that the brush is put into the wash position
prior to the front of the car arriving at the brush. This will entail deactivating the retracts
before the vehicle reaches the brush and setting the look ahead to check for the proximity
of the next car.
Mechanical Adjustment of the Wrap Hanger Arms
•
Install the unit so that the legs are plumb, the hanger arms are level when at the rest
position and the mounting bearings are positioned perpendicular to floor (no pitch).
•
The rest position will vary with operator preference and region.
•
The two brushes should return to the rest position (middle of the tunnel) with no air
pressure and no pitch to the bearings.
