Compressor (902404) and Pneumatic System
TP-4945001-00 2-4
Chapter 2 Operation
2.1 Manual Operation
Assemble control valve kit, WB part number 913882 by cutting the hose to length and assembling per
drawing B-3818, figure 2-1. Attach control valve kit to
compressor assembly by attaching the male ¼”
NPT thread on the control valve kit to the brass ¼” NPT street tee. Use Teflon tape or paste on threads
before assembly.
The control valve is a spring centered, three position, three way valve with all ports blocked in the center
position.
The ‘A’ or exhaust port should be plumbed to the mast. The ‘P’ or pressure port should be
connected to the compressor assembly.
With the hand lever facing the operator push the lever forward to extend the mast and pull the lever to
retract the mast. A hose or elbow can be plumbed to the open port to direct the exhaust air away from the
operator. The pressure gage on the right side of the control valve indicates the pressure in the mast
when the valve is in the center or non-actuated position.
2.2 Electric Operation
When the pneumatic system is equipped with a solenoid operated valve it should be wired like Figure 2.2.
The solenoid valve is a double solenoid, three position, four way valve configured as shown below.
The up solenoid ‘A’ is energized to shift the spool valve to connect the pressure port ‘P’ to the ‘A’ port
which provides a path to allow air pressurized air
into the mast. When the down solenoid ‘B’ is energized
the ‘A’ port is connected to the exhaust port ‘EA’.
