2.4 HYDRAULIC CONNECTION
The drive unit and hydraulic control unit are connected by two
hydraulic lines, each with an outside diameter of 5/16 in. (0.8
cm), an inside diameter of 5/32 in. (0.4 cm), and a 2,500 psi
(170 bar) rating).
Caution: After removing the nylon piping on the drive unit do not
rotate the splined shaft while you are connecting the hydraulic
lines to avoid squirting hydraulic fluid.
Remove the nylon piping connecting the two hydraulic pipe
fittings on the drive unit. Clean up any spilled hydraulic fluid.
Be sure the hydraulic lines are free of any debris by flushing them
with a jet of compressed air. Then attach one line to each fitting
on the drive unit.
Attach the other end of the hydraulic lines to the pipe fittings on
the hydraulic control unit (fig. 13).

The control unit fitting beside the green by-pass screw must
be connected to the drive unit fitting that is within the property
(fig.12-ref.B). The control unit fitting beside the red by-pass screw
must be connected to the drive unit fitting that is outside the
property (fig.12-ref.A). These connections make it possible to
adjust the force given to the gate when opening using the green
by-pass screw and when closing using the red by-pass screw.

How to install the Flex Hose on the hydraulic control unit
(fig. 13)
1. Screw item B onto the hydraulic hose A (counter clock-wise)
until tight.
2. Screw item C into item B & A. To get the threads to catch
up, you must push C into B & A as you turn it (clock-wise)
