RAISE-LOWER CONTROLS/WHEEL DRIVE SYSTEM
WHEEL DRIVE SYSTEM
The 4030 Series features a cable-controlled hydraulic
powered gear motor system with infinite Forward-Neutral-
Reverse (F-N-R) speed adjustment. This is controlled by
the operator through the speed control handle located on
the control panel. The saw is designed with a locked axle
drive and can travel forward at transportation speeds up to
275 feet per minute.
A bi-directional variable displacement transmission pump
powers two hydraulic wheel motors that are directly coupled
to the wheels. This design provides vehicle propulsion in
both forward and reverse depending on the position and
direction of movement of the F-N-R control handle. The
wheel drive system also provides dynamic braking action.
Refer to Figure 28.
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.
