HYDRAULIC UNIT 174
C
Connecting double-acting cylinder
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.
A
Do not hold the lever or switch in the extend (A) or
retract (B) 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.
A
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.
C
Connecting hydraulic motor
1. Connect the pressure hose (2) to the upper coupler
and the return hose (3) to the lower coupler of the
same valve.
2. When the control lever or switch is assigned to the
float (C) position, the motor is off.
Move the lever or switch to retract (B) position to
operate the motor.
To stop the motor, move the lever or switch from
retract (B) position to the float (C) position.
A
When operating continuous flow equipment, the
remote control valve lever or switch must not be
moved to the neutral (N) or extend (A) position as
damage to the equipment may result. Always select
the motor mode function when operating with
hydraulic motor.
(A) "EXTEND"
(B) "RETRACT"
(N) "NEUTRAL"
(C) "FLOAT"
(D) "DETENT"
(Detent function)
A
Set the switch to the "DETENT" position, and it is held
at this position unless it is returned to the "NEUTRAL"
position.
This function is useful for implements that need
constant oil feed.
