100 Ton Ram Instruction Manual
Slide the hose with the ferrule on over the shank
until the ferrule contacts the shoulder of the stem.
Make sure you align the ferrule with the second
mark from step 6. Make sure the pocket has been
maintained.
Important! If there is an insufficient pocket for the
rubber to displace into, damage may occur to the
stem, ferrule, and /or hose.
While holding the hose and ferrule firmly against the
stem shoulder, engage the ram cylinder by stepping
on the foot pedal (or depressing the “ON” button on
the remote control.) The internal expansion
operation is complete when the hose and stem
assembly is pushed completely over the internal
expansion plug. Releas the foot pedal or “ON”
switch.

Note: If the gauge reads 10,000 PSI before internal expansion is complete, stop. Contact Dixon for further
assistance. During internal expansion never stand directly in front of the ram. Visually inspect the coupling.
