that pump pressure systems operate at peak efficiency. To maintain proper pressure and to protect
diaphragm rubber, systems must be full of hydraulic fluid at all times.
Operator must remove pressure from gauge before starting steps below.
STEP ONE
Remove the cap from check valve on
the diaphragm protector.

STEP TWO
Attach aluminum hand pump to the check valve.Do not tighten swivel completely. Aluminum Hand Pump

STEP THREE
Fill the hand pump reservoir with Crown’s red hydraulic fluid.

STEP FOUR
Push on the hand pump plunger to move the hydraulic fluid towards the system. Air bubbles will emerge between the hand pump and check valve.

STEP FIVE
Once you see a small amount fluid coming out of the connection completely tighten swivel to the check valve. There should be no bubbles coming out of the connection at this point.

STEP SIX
Remove the 1/8’ pipe plug in the gauge, making sure to tape the thread with Teflon tape.

STEP SEVEN
Turn diaphragm protector upside down so that you can see the diaphragm rubber.

Rubber Cup Diaphragm
STEP EIGHT
Pump hydraulic fluid into the system until the rubber collapses its side together at approximately 38 PSI. The diaphragm sides will be just touching each other.
Rubber cup will collapse and sides will be just touching at
approximately 38 psi.
