When not attached to the tractor, always
use the lifting hook to hoist the machine
for maintenance. (See Figure 4). Use ex-
treme caution when using lifting hook be-
cause center of gravity is affected by ad-
ditional attachments and the unit may
shift rearward.
When installing tines, performing any ro-
tor shaft service, or removing debris from
the rotors, ensure that the rotor shaft does
not rotate because a serious pinch injury
could occur.
