PUSHING, TOWING, AND TRANSPORTING

THE MACHINE

PUSHING OR TOWING THE MACHINE

If the machine becomes disabled, it can be

pushed from the front or rear, but towed only from

the rear.

The propelling pump has a bypass valve to

prevent damage to the hydraulic system when the

machine is being pushed or towed. This valve

allows a disabled machine to be moved for a

very

short distance

and at a speed to not exceed 1.6

kp/h (1 mph). The machine is NOT intended to be

pushed or towed a long distance or at a high

speed.

ATTENTION! Do not push or tow

machine for a long distance and without

using the bypass valve, or the machine

hydraulic system may be damaged.

Turn the bypass valve 90

from the normal

position before pushing or towing the machine.

The illustration shows the bypass valve in the

pushing or towing position.

TRANSPORTING THE MACHINE

1. Position the rear of the machine at the

loading edge of the truck or trailer.

FOR SAFETY: Use truck or trailer that

will support the weight of the machine.

NOTE: Empty the hopper before transporting the

machine.
