180° Stop Valve
A
Valves with One Adjustment Screw –
Loosen the
jam nut on the stop valve adjustment screw and turn
the screw IN (clockwise) until it stops. Back out one
turn.
Valves with Two Adjustment Screws –
Loosen
the jam nut on the stop valve adjustment screws
and turn the screws OUT (counterclockwise) until a
groove marking the maximum-out position is visible.
Adjustment screws should be adjusted equally.
IMPORTANT:
Backing the adjustment screws out
past the groove will cause hydraulic leakage.
B
Using a load that: A) is the heaviest to be lifted,
or B) requires maximum motor torque, rotate the
attachment back and forth to the stops at full
speed for 1–2 minutes before making adjustments.
Observe whether the attachment fully completes its
rotation slowly into the hard stop.
C
If rotation does not continue into the hard stop, rotate
the stop valve off the ramp and turn the adjustment
screw IN (clockwise) one-eighth turn. Test for
complete rotation slowly into the hard stop.

Repeat Step C until the attachment fully completes
its rotation slowly into the hard stop. Tighten the jam
nut on the adjustment screw.
