Installing Accelerators
A new pair of accelerators should be installed on a cutterbar disc whenever the old ones are damaged or worn to the
extent that they can no longer effectively move crop off the disc and into 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.
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.
