Revision A
Removing Accelerators
Accelerators need to be removed from cutterbar discs when they are damaged, or when they become worn out and can
’
t
effectively move crop from the discs to the conditioner.
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
header is raised, always close the lock-out valves, and place blocks under the header. Never work on or beneath an
unsupported header.
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.
IMPORTANT:
Always replace accelerators in pairs to ensure that the discs remain balanced.
