Loose Pointers Loose Knobs Follow the steps below to ensure

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 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.

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.

STEP NINE
