Towing speed must NOT exceed 3 mph (5 km/h). Do NOT tow the disabled unit more
than 6 miles (10 km).
The disabled unit will be difficult to steer as there is no hydraulic pressure available.

Do not tow the Belt Loader if it has experienced a hydraulic failure as the unit may not
be steerable.

of no more than 5 mph (8 km/h). If the required towing distance is more than 1 mile
(1.6 km), the drive shaft must be removed from the Belt Loader to avoid transmission
