5.10 ADJUSTMENT OF LIMIT VALVES
In T900 trailer, the switching between the supply circuit of the wall sliding horizontal cylinders
(3) and the telescopic cylinder (2) and the supply circuit of the wall rising vertical cylinders (4)
is performed by the limit valve (6). The adjustment of this valve is performed by means of
adjustment bolt (8) when the sliding wall is maximally extended. The conduit arm (1) should
be positioned so that the polyurethane spring (5) is squeezed by at least 10 mm and the
angle between individual arms does not exceed 160°. The valve lifter must be extended to a
distance of 1.5 - 2 mm. After the adjustment, secure bolt (8) with counternut (9).
The adjustment of limit valve (7) is performed when the wall is maximally lowered. The limit
valve lifter must be extended to a distance of 1.5 - 2 mm. After the adjustment, secure
adjustment bolt (8) with counternuts (9).
ATTENTION
Work connected with setting, adjustment and replacement of limit valves should be
entrusted to specialist establishments having the appropriate technology and
qualifications for this type of work.
Make certain that the machine does not pose any threat after adjustment of the valves.
