Title: How to recharge a pump pressure system
1How to Charge a Pump Pressure System

Knobs
Follow these steps 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. Remember to check the components to the
left regularly. Operator must remove pressure
from gauge before starting steps below.
Inspect Gauge Protector for Cracks, Cuts, Dents,
Leaks
Inspect Hose Connections
Inspect Hydraulic Hoses for Cuts, Cracks, Kinks
3Step One
Diaphragm Protector (CD106)
- Remove the cap from check valve on the diaphragm
protector.
Check Valve (CC102)
4STEP TWO
Attach aluminum hand pump to the check valve. Do
not tighten swivel completely.
Aluminum Hand Pump (CH103)
5Step Three
Crown Hydraulic Fluid (CW15)
- Fill the hand pump reservoir with Crowns red
hydraulic fluid.
Aluminum Hand Pump (CH103)
6STEP 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.
Aluminum Hand Pump (CH103)
7STEP FIVE
Aluminum Hand Pump (CH103)
- 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.
Diaphragm Protector (CD106)
8STEP SIX
Remove the 1/8 pipe plug in the gauge, making
sure to tape the thread with Teflon tape.
Recharge Kit (CK100)
9STEP SEVEN
Diaphragm Protector (CD106)
- Turn diaphragm protector upside down so that you
can see the diaphragm rubber.
Rubber Cup Diaphragm
10STEP 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.
11STEP NINE
- Remove the hand pump from the check valve.
Aluminum Hand Pump (CH103)
Check Valve (CC102)
12STEP TEN
Replace the check valve cap.
