2.6 Controls for the remote control valves
on the rear fender (if equipped)
The left and right tyre fenders are equipped with the
2nd-segment remote control valve operation switch.
Before activating the switch, make sure that there is
nobody and no obstacle within the implement working
range.
The valve acts only while the switch is held down.

(2) Retract switch for 2nd remote control valve

3.1 Connecting cylinder and hydraulic
motor
Connecting single-acting cylinder
1. Connect the hose to the lower coupler of the valve.
2. To extend a single-acting cylinder, move the control
lever or switch to extend (A) position.
Manually return the lever or switch to the neutral
(N) position to stop the cylinder when it has
reached the desired position.
3. To retract a single-acting cylinder, move the lever or
switch to float (C) position.
IMPORTANT :
• Always use the float (C) position to lower a
single acting cylinder. The retract (B) position is
for double acting cylinders only.
• Do not hold the lever or switch in the extend (A)
position once the remote cylinder has reached
the end of the stroke, as this will cause oil to
flow through the relief valve. Forcing oil
through the relief valve for extended periods
will overheat the oil.
• Hold the lever or switch at the float (C) position,
and the remote cylinder can be fully extended
and retracted. Select this float (C) position when
you want to run the implement along the terrain.
(A) “EXTEND”
(B) “RETRACT”
(N) “NEUTRAL”
(C) “FLOAT”
Connecting double-acting cylinder
1. Connect the pressure of the load side of implement
cylinders to the lower couplers of each valve, which
have built in load check valves to prevent leaks.
