When using a double-acting cylinder, connect the
feed hose from the cylinder to the bottom coupler
and the return hose to the top coupler. To extend a
double-acting cylinder, pull the remote lever
rearward to position 2. To retract the cylinder,
push the lever forward to position 3. The cylinder
can be put into the float position by pushing the
remote lever full forward in position 4.
When using a single-acting cylinder, connect the
supply line to the lower coupler. To extend the
cylinder, pull the remote lever rearward to
position 2. To retract, push the control lever fully
forward to “float,” position 4.
IMPORTANT: Always use the float position to
lower a single-acting cylinder. The retract
position is for double-acting cylinders only.

To disconnect the coupler, make sure that the
remote control lever is in the neutral position and
the engine is off. Check to be sure that the
implement has its transport stops in place or is
lowered to the ground.
Grasp the coupler tip behind its hose connection
and firmly pull the tip straight back from the
coupler. Cover the tip with a protective cap to
minimize contamination.
