Before commencement of work with
tools attached to the front 3-point hitch it
is recommended to adjust the throttling
valve (3) so that the time necessary for
lowering of tools from the highest to the

turning the valve body counterclockwise
(in direction of the arrow) the lowering
speed increases. When adjusting the
valve, the levers of the front hitch valves
shall be horizontal.
