Raise Valve Operation Check
The raise valve is a normally open (N.O.) valve in the hydraulic system. Perform the fol-
lowing procedures to check the operation of the raise valve.
1. Disconnect the black and yellow wires from the solenoid, to the valve at the
wire connector, Figure 4-5.
2. On the upper control box, select
UP on the direction selector switch while de-
pressing the
ON pushbutton. This should cause the motor to run without the plat-
form raising.
3. If the platform raises, the raise valve must be cleaned or replaced.
4. Reconnect the wires at the connector between the solenoid and the raise valve
upon determining that the valve is functioning properly.
