CW (clockwise) until it stops.
4. Return the valve bank manual overrides to the
neutral position. See below for more detailed

Failure to return the
valve bank manual
overrides to the neutral position can result
in unexpected crane movement.
5. Have the unit serviced immediately to restore
remote control functionality.
If the remote control malfunctions, follow the steps on this and the following page to operate
the crane manually. Firstly, determine which type of valve bank you have and follow only the

Operating the Solenoid Valve Plungers
While the sliding collar is in the locked
position the plunger can’t be pushed or
pulled. To unlock the collar so you can
manually operate the valve, place your
thumb on the end of the knurled plunger
knob and two ngers on the sliding col-
lar, like holding a syringe. Keeping the
knob in place with your thumb, slide the
collar toward the knob. When the two
are together, the plunger position is un-
locked. Move both together and push
in or pull out based on the instructional
decal. When done, return both to center
(neutral) position and then slide the col-
lar to the locked position.
