Hydraulic test equipment allows you to observe the
amount of oil pressure and oil flow in a circuit under
various conditions.
Hydraulic testers may vary significantly in size,
construction, accuracy, and cost. The decision as to
which tester to purchase should be influenced by
what type of tests will be performed on all the hy-
draulically powered equipment in the shop.
High And Low Pressure Test Gauges
Low pressure gauge 1000 PSI, high pressure gauge
5000 PSI, and associated hoses and fittings.
Figure 4
Hydraulic Pressure Gauges
(Quick Disconnect type)
For use on Toro machines that have test ports with
quick disconnect adapters. 1000, 5000, and 10,000
PSI gauges with extension hose and quick discon-
nect fittings.

Hydraulic Tester
(With Pressure and Flow Capabilities)
1. INLET HOSE: Hose connected from the system
circuit to the inlet side of the 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
provide accurate readings 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
accommodate pressure beyond the capacity of the
low pressure gauge, 0 - 5000 PSI.
5. FLOW METER: This meter measures actual oil
flow in the operating circuit. The reading is given in
gallons per minute (GPM) with a gauge rated at 15
GPM.
6. OUTLET HOSE: Hose from the outlet side of the
hydraulic tester to be connected the hydraulic
circuit.
