REAR UNLOAD OPERATION
Whenever adjusting, cleaning, lubricating or otherwise
servicing this forage box, you must shutoff and lockout
power to the box. Because this box can be truck
mounted or powered by a tractor, methods vary. On
truck mounted units, the connection between the PTO
and box is permanently installed and not intended to be
disconnected. On trucks, disengage the PTO drive, turn
off the engine, set the parking brake, remove the ignition
keys and keep them in your possession to prevent any
-
one else from accidentally applying power to the box un
-
expectedly. On tractor pulled units, the connection
between the tractorPTO andbox isby a removablePTO
drive shaft. For tractors, disengage the PTO drive, turn
off the engine, set the brakes and disconnect the PTO
drive shaft from the tractor.
Throughout this manual, when directed to shutoff and
lockout power, be familiar with the previously described
procedures for the type of machine you are operating.
