Operational Performance and Controls
Understanding Air-Over-Oil
Swing Flow Controls
These are the Flow Controls connected to each Oil Reservoir. They control the hydraulic
flow rate from the cylinder. On each stand (leg assembly), there are two such controls. One
is for controlling the rate of Swing Retract and the other for controlling the rate of Swing
Extend.
The orientation of the hydraulic Flow Controls is set so that peak pressures seen in
operation are contained within the Hydraulic Cylinder. When adjustments are being
considered, the technician should be aware that the focus is not at what rate to allow flow IN,
but the rate to allow flow OUT of the Hydraulic Cylinder. See the diagram below to better
understand.
Flow Control Valve
: Turning the Flow Control knobs adjusts the
“Controlled Flow” of oil being discharged from the Hydraulic Cylinder
into the Oil Reservoir.
This Flow Control Valve has a “Flow Direction” arrow engraved on its
side that indicates free-flowing oil that passes through the internal check
valve into the Reservoir at a rate determined by the force of the user-set
Controlled Flow.
Understanding Regulator Adjustments
1RGLTR175
This is the adjustable control of the penetration pressure seen on the car. This control also
affects the settings of the swing flow controls due to their operation being in series with this
air regulator (Small Regulator on the Air Panel).
1RGLTR650
This is the primary adjustment with concerns of the head extend/ retract speed. The sole
setting of the heads extend speed and when used in series with a needle valve flow control
affects the rate of head retract (Large Regulator on the Air Panel).
