NOTICE!
Before the installation of the filters check hoses
and connections for cleanliness.
The flushing filter must be installed in the low pres-
sure side in the return flow to the pump, so that
only cleaned oil will enter the travel pump.
With the connection shown in the illustration the
travel pump must therefore be actuated to forward
direction.
1. Disconnect the high pressure hose (8) from the travel pump
(port B) and connect it with the flushing hose (6) flushing filter
inlet "IN" (see chapter "Flushing diagram travel system").
2. Connect the flushing hose (5) flushing filter outlet "OUT" to
the high pressure port (B) on the travel pump.
1. Take the drum drive motors (9 & 10) out of the hydraulic cir-
cuit and join the hoses together.
