Additional pneumatic troubleshooting information:
Air enters the unit through hose 100 and is distributed to the solenoids through the manifold
Hose 110 feeds the motor solenoid. Air flows through hose 111 and 112 when the motor is on.
Hose 120 feeds the clamp solenoid. Hose 121 is normally pressurized, keeping the clamp in the open
position. When the clamp is closed hose 122 become pressurized. Air flows through lines 121, 122,
and out the breather vents of the clamp solenoid when opening or closing.
Hose 130 feeds the lift solenoid. Hose 131 is normally pressurized, keeping the lift in the bottom
position. When the lift is raised hose 132 becomes pressurized. Air flows through lines 131, 132, and
out the breather vents of the lift solenoid when raising or lowering
Hose 140 feeds the spray solenoid. Air flows through the tubing when the sprayer is on.
