Adjustments and Testing
Adjustments
1. Water Pressure to Nozzles is adjusted at the HP bypass valve on the Water Pump
station to approximately 800psi.
2. Oscillating Speed Adjustment (optional Omni Top)
(1) The oscillating speed of the manifold can be adjusted at the flow control on the
hydraulic power pack.
(2) Speed should be set to 60-70 RPM as counted at the hydraulic motor shaft.
3. Tracking Speed Adjustment (optional Omni Top)
(1) The manifold has two air pressure regulators on the air manifold to control
tracking. Should be set to 60 psi.
(2) The manifold has a brass flow-control valve on the reservoir to regulate how fast
the manifold tracks the vehicle as it passes and a black plastic flow-control valve
on the air cylinder to control how quickly it returns to the ready position, facing the
tunnel entrance.
4. Check the Direction of Motor Rotation
(1) Rotation of the electric motor should be CLOCKWISE as viewed from the fan
(rear) side of the 2hp electric motor.
(2) Check for proper oil level in the speed reducer and make sure a breather plug is
inserted at the highest port on the speed reducer.
