SQUEEZE COIL
KNIFE/HOOK
COIL
When the switch is in the Rotate position (B), no power is supplied to any of the coils at the hydraulic manifold. Valves #1
and #3 are normally closed and valve #2 is normally open. When the switch is moved to the Squeeze Position (A), 12V
power goes to both the Green and Red wires. The Green wire opens valve port #1 and the Red wire closes valve port #2
diverting oil flow to the Squeeze cylinders. When the switch is moved to the Cut/Grab position (C), 12V power goes to
both the White and Red wires. The White wire opens valve port #3 and the red wire closes valve port #2 causing hydraulic
flow to go to the Cut/Grab cylinders.
