5. Install the two hydraulic hoses. Apply one wrap of
teflon tape to the threads on the end of the hose.
Remove the pipe plugs from the pump valve, one
port is marked “ADV” the other is marked “RET”.
Install a hose in each port. Figure 5.
6. Connect the hose from the “ADV” port to the
hydraulic cylinder coupler located near the base
of the cylinder. Make sure there is no dirt or
debris in either half prior to assembly. Push the
hose coupler firmly into the cylinder coupler, then
tighten coupler collar. Connect the hose from the
“RET” port to the remaining cylinder coupler.
Figure 6A & 6B.
IMPORTANT: The hose coupler must be firmly
seated in the cylinder coupler and held
tightly while turning the coupler collar.
Hand tighten the collar.
Do not use
tools to tighten. Failure to properly
assemble couplers will inhibit oil flow.

"–4" frame holes for
mounting all sizes of conduit bending shoes. See
figure 8. For smaller sizes of conduit, the cylinder
plunger must be advanced to position the roller
assembly against the follow bar.
