Connecting Hydraulic Hoses to the Ram
Connect the hydraulic lines from the hydraulic power
supply to the ram.
1. Connect the RAM DOWN hydraulic lines (D, C) to
the RAM UP connectors on the top of the ram.
2. Connect the RAM UP hydraulic lines (A, B) to the
RAM DOWN connectors on the bottom of the ram.
See F
IG
. 5.
Connecting Ram Air Hoses to Hydraulic
Supply
Connect the air hoses from the air control to the hydrau-
lic supply.
1. Connect the RAM DOWN line on the hydraulic sup-
ply to the RAM DOWN bulkhead on the air control.
2. Connect the RAM UP line on the hydraulic supply to
the RAM UP bulkhead on the air control.
3. Connect the hydraulic pilot down line to the hydrau-
lic pilot down bulkhead on the air control.
4. Connect the hydraulic pilot up line to the hydraulic
pilot up bulkhead on the air control.
5. Use the ram hand valve lever to raise the ram to the
UP position. If the ram goes down instead of up,
check your hydraulic line and air line connections;
you may have incorrectly connected the lines.See
F
IG
. 6.
6. After you have determined the hydraulic lines and
air lines are connected correctly, run the ram up and
down five or six times to bleed air from the hydraulic
lines.
Starting Up the Hydraulic Ram for the First
Time
You will need the following tools:
• 9/16 in. open-end wrench
• 5/32 in. hex key
Ram down pressure is controlled by the in-line hydraulic
fluid regulator. Before you start up the hydraulic ram,
you must determine the amount of air pressure needed
to produce the desired hydraulic pressure.
The maximum hydraulic pressure you can set is 225 psi
(16 bar, 1.6 MPa). Use the table, F
IG
. 7 below as a
guide for setting the regulator.
