7.4 TRAVEL FORWARD FUNCTION
The circuit segment below shows the flow path when
both the travel function levers are pushed forward to
drive the machine in the forward direction. This function
can operate at the same time as the “Lift” function
because the lift function is fitted with a “Series” spool.
However for safety reasons it is recommended travel is not attempted with the lift arms and attachment raised.
Note how the valve flow for the left hand drive motor
doubles back through the series spool to connect with
the parallel valve of the right hand drive motor.
