Check that stop valve (1) is located at LOCK position (b).
(a) FREE: Hydraulic oil flows (direction of arrow is parallel
to longitudinal direction of arm)
(b) LOCK: Hydraulic oil does not flow (direction of arrow is
at right angle to longitudinal direction of arm)
• When setting the FREE or LOCK position of the stop
valve, remove bolt (1) and washer (2) fit lever (3) and
refit bolt (1) and washer (2) rotate valve to furthest po-
sition clockwise or anti-clockwise. After setting remove
