Model 293.32 HSM Electrical Connections
The Model 293.32 HSM is equipped with a control manifold that permits selection of various hydraulic
pressures. Control cable connections must be made between the high and low solenoids of the HSM and
the system controller. The following figure shows the locations of the high/low solenoids on HSM.
