Operating Double-Acting Cylinders
Connect the feed hose (1) between the piston end of
a double-acting cylinder and the left--hand coupler on
the remote control valve. Connect the hose (2)
between the right--hand coupler on the same valve
and the rod end of the cylinder. To extend a
double-acting cylinder, move the control lever or
joystick to the ‘extend’ (raise) position.
To retract a double-acting cylinder , move the control
lever or joystick through neutral to the ‘retract’ (lower)
position.

Further movement of the lever or joystick, beyond
the ‘retract’ position, will select ‘float’ which will allow
the cylinder to extend or retract freely. This feature
is of material assistance when carrying out work with
equipment such as scraper blades and loaders.

Operating Single-Acting Cylinders
Connect the hose (1) from a single-acting cylinder to
the left--hand coupler (2) on the remote control valve.
To extend a single-acting cylinder , move the control
lever or joystick to the ‘extend’ (raise) position.
Manually return the lever or joystick to the neutral
position to stop the cylinder before it is fully extended
or allow the valve to return to the neutral
automatically when the cylinder reaches the end of
it’s stroke.
To retract a single-acting cylinder, move the lever or
joystick beyond the ‘retract’ (lower) position to the
‘float’ position.
