To retract the hoist cylinders, hydraulic oil must bypass the hoist cylinder counterbalance
valves by flowing through the flow control valves. The flow control valves are located on the
top side of the base of the hoist cylinders.

Do not loosen the 1 inch hex nut or remove the stem on the flow control
valve when the cylinder is pressurized due to a raised boom or load. High
hydraulic pressure exists which, if released, the boom could drop and
cause severe personal injury.
(a) Loosen the 3/4 inch hex nut locknut on the flow control valve stem (located on the top
side of each hoist cylinder base end).
(b) Unscrew the stem with a 3/16 inch allen wrench to the internal stop.
Actuate the emergency steering pump by turning the emergency steer switch
and the starter-run control switch to the ON position.
Move the hydraulic joystick forward to lower the boom until the load or forks are about 24
inches above ground level.
Return the system to normal operation as follows:
(a) Return the hydraulic joystick to the neutral (center) position.
(b) Turn the starter-run control switch and the emergency steer switch to the OFF position.
(c) Screw both flow control stems in until they are seated and tighten locknuts.
(d) Install the transmission cover.
