3.3.7 Connecting a small cylinder for the mast-lower-
ing system
The dual non-return valve
(HT5198), the flow con-
trol valve (HT5161), the
4/3 valve (HT5017) and
the connections are pre-

When putting into opera-
tion, the flow should be

valve (HT5161). The flow
is related to the speed of

The pressure should be
set in the junction box.
Always start with the lower pressure (connection 5-7).

At least 1 load-sensing valve should always be fitted. This can
be a '1-step load-sensing' valve or a '2-step load-sensing'
valve.
'1-step load-sensing' valve
The valve (HT5032) and
the connection are pre-
mounted.
Fit the hose.
'2-step load-sensing' valve
The shuttle valve
(HT5038), the reduction
valve (HT5037) and the
4/3 valve (HT5017) are
pre-mounted.
The connections are pre-
mounted.
Fit the hose.
When putting into opera-
tion, the reduction valve
