Startup

Initial

Flow Controls
Pressure settings on each boom will effect how fast the booms move in and out, and must be set before setting the
flow controls. At this point both flow controls on each boom extend cylinder should be open completely (turn counter-
clockwise).

1) Set initial boom extend pressure per the chart below.
• Driver side: 20
• Passenger side: 40
2) Run a test vehicle and adjust the pressure on each side for proper penetration while on the side of
a large car or van. See sketch below.

Decrease air pressure if
more mirror clearance is
required

3) Run a test vehicle and close the front flow control (rod end side of the cylinder) as necessary to
keep the wheel from leaving the vehicle front fender. Higher line speeds require this flow control to
be open more, so the wheels can get out of the way of the vehicle.
4) Opening the flow control too much can cause the wheel to leave the front of the vehicle and
bounce back into the side.
5) Close the rear flow control (entrance side of the extend cylinder) to slow the inbound motion of the
wheels. How much this gets closed depends on your air pressure and conveyor speed.
At the rear corner of the vehicle the wheel should walk around the back a little faster than the
boom can come in. This can help keep the boom from shooting over the vehicle when passing
wheel wells and provide better cleaning of the vehicle back.
The boom pivot points are inside of the vehicle sides, and allows the wheels to “chase” the back of
the vehicle somewhat. Start with flow controls on the rod end side of the cylinder at 3 turns out
from closed, and the entrance side flow controls 4 turns out from closed (see “Hydraulic
Installation page).
