Return Flow Selector Valve
The return flow selector valve (1) has a one-way (3) and a
two-way (2) position for operating optional equipment. It is
located behind the engine hood.
A variety of optional one-way and two-way flow
equipment is available for use on this machine. A hydraulic
breaker is an example of one-way flow equipment; a tilt
bucket is an example of two-way flow equipment.
Directional Arrows
The directional arrow (1) on each of the track frames
indicates forward movement of the machine. Check these
arrows before using the travel control levers/pedals. The
track drive sprocket is at the rear of the track frame.
If the track frame is facing backward, the travel direction
will be opposite the maneuvering direction of the travel
control lever/pedal. The machine will move forward when
you pull the control levers backward and backward when
you push them forward. Left and right control directions are
also reversed when the track frame faces backward.
