Hydraulic Test

The system has been hydrostatic and function tested at the factory before shipping.
This test is to discover if any leaks have developed in the hydraulic fittings during ship-
ment.

Set-up/Start-up Procedure
Check the Reservoir (4) to see the hydraulic fluid is at the proper level.
Close Hand Pump Isolation Valve (8).
Use the handle supplied with the pump to raise the pump clevis. This will draw
hydraulic fluid from the reservoir (4) into the hand pump.
Pull the pump handle down to discharge the hydraulic fluid into the cylinder of
the Actuator (1). Repeat until you see the hand pump is working correctly.
Repeat operating the handle until the actuator has completed its power stroke.
Push Hand Pump Bypass Valve (16) located on the bottom of the hand pump
and pull the pump handle down, retracting the pump ram back into the pump
body.
Slowly open Manual Bypass Valve (Lockable) (19) to allow the actuator to
spring-return to its Fail-safe Position.
After the actuator has returned to its Fail-safe Position and pressure has been
released, close Manual Bypass Valve (Lockable) (19).
Open the Hand Pump Isolation Valves (8) to return to automatic operation.
Open Hand Pump Isolation Valve (8) and ensure Manual Bypass Valve (Lockable)
(19) is closed.
Using the supplied handle, stroke Hand Pump (13) four or five times and stop.
Allow the unit to remain under pressure for a few minutes and check all
fittings
for leakage.
If any leakage is found, release the pressure by slowly opening Manual Bypass
Valve (Lockable) (19). Repair any leakage and repeat the pressure test from step
4.4.1.
Push Hand Pump Bypass Valve (16), located on the bottom of the hand pump,
and pull the pump handle, retracting the pump ram back into the pump body.
