DANGER
To prevent injury or death from the unexpected start-up or fall of a raised machine, always stop the engine and remove
the key from the ignition before leaving the operator's seat or making adjustments to the machine. If the rotary disc
pull-type is raised, always close the lock-out valves, and place blocks under the rotary disc pull-type. Never work on or
beneath an unsupported rotary disc pull-type.
DANGER
Ensure that all bystanders have cleared the area.
WARNING
Disc blades have two sharp cutting edges that can cause serious injury. Exercise caution and wear gloves when working
with, or near, blades.
1. Park the machine on a flat, level surface.
NOTE:
To prevent oil from spilling from the cutterbar while you are removing the disc spindles, ensure that the rotary disc
pull-type is on a flat, level surface and that is tilted all the way back.
2. Position the rotary disc pull-type at an appropriate height for the task.
