Hydraulic Tester – With Pressure and Flow Capabilities
You must have o–ring face seal (ORFS) adapter fittings
for this tester to use it on this machine.
1. INLET HOSE: Hose connected from the system cir-
cuit to the inlet side of the hydraulic tester.
2. LOAD VALVE: If required, upon turning the valve to
restrict flow, a simulated working load is created in the
circuit.
3. LOW PRESSURE GAUGE: Low range gauge to pro-
vide accurate reading at low pressure, 0 – 1000 PSI.
This gauge has a protector valve which cuts out
when pressure is about to exceed the normal range
for the gauge. The cutout pressure is adjustable.

4. HIGH PRESSURE GAUGE: High range gauge to ac-
commodate pressure beyond the capacity of the low
pressure gauge, 0 – 5,000 PSI.
5. FLOW METER: This meter measures actual oil flow
in the operation circuit, with a gauge rated at 15 GPM.
6. OUTLET HOSE: Hose from the outlet side of the hy-
draulic tester to be connected to the hydraulic system
circuit.
