PAGE 36 — PS7060 MULTIQUIP SAW • OPERATION MANUAL — REV. #2 (06/02/08)
Wheel Drive System
The PS7060 saw features a cable-controlled hydrostatic
transmission with infinite Forward-Neutral-Reverse (F-N-R)
speed adjustment. This is controlled by the operation through
the control handle located on the operator control panel. The
saw is designed with locked axle drive, and can travel at speeds
up to 275 feet per minute.
■
To increase the forward speed, slowly move the control
handle FORWARD.
■
To decrease the forward speed, pull the control handle
BACKWARD.
■
When the control handle is in the Neutral position the saw
will have neither a forward nor reverse motion.
■
As the control handle is passed backward through the
neutral position the saw will start to move in REVERSE.
Reverse speed is also controlled by the position of the
control handle.
A bi-directional variable displacement transmission pump
powers two hydraulic wheel motors that are directly coupled to
the wheels. The hydrostatic transmission provides vehicle
propulsion in both forward and reverse depending on the position
and direction of movement of the F-N-R control handle. The
hydrostatic transmission also provides dynamic braking action.
