Rear remote control valve(s)
Before removing the protective caps for connecting the male couplings, remove all the debris that has accumulated
on the pressure points to avoid contaminating the hydraulic system.
Quick coupler
One, two or three control valves using the same oil as
the hydraulic lift circuit to which they are connected can
be fitted to your tractor for remote control of single-acting
and double-acting cylinders.
Each valve has two 1/2” quick−fitting female “Push− Pull”
couplers which can be connected to pressurised male
couplers, available as an optional. You can thus connect
the control cylinder lines with two hands.
Push them in to fit them and pull them out to release
them from the female couplers, but only after first:
• stopping the engine
• lowering any implements connected to the lift;
• thoroughly cleaning the two mating parts.
NOTE: When not using the female couplers, protect them
with the plastic caps.

Single/double-acting switching
To switch the control valves to:
• single−acting, slacken screw
(1) near to the valve con-
trol lever pivot until it stops.
• Double-acting, fully tighten the screw
(1) .
When using single-acting, in order to quickly identify the
coupler to which the implement is to be connected, ac-
tuate the distributor lever and observe the two lines to
which the couplers are connected: the line carrying the
oil should move.
For greater safety, check that the line to which the im-
plement is connected using single-acting, is the line on
the valve body connected furthest from the change-over
screw.
