IMPORTANT:
Right discs (A) and left discs (B) are timed and must be at a 90 degree angle from adjacent discs when reinstalled.
Misaligned discs could result in the following:
•
Discblades of co-rotating discs hitting each other
•
Discblades of diverging discs hitting adjacent discs
Check clearance (timing) before tightening spindle to the cutterbar. Turn disc by hand to ensure discblades do not contact
each other or adjacent discs. If contact occurs or alignment is incorrect, lift spindle to clear mounting bolts, rotate spindle
180 degrees (ensuring that base does not turn), and reinstall. Recheck timing before bolting hub down and tightening all of
the nuts.
NOTE:
Right discs (A) and left discs (B) are slightly offset as shown, depending on which idler gear the spindle is turning.
•
Spindles that rotate clockwise have left-leading threading
•
Spindles that rotate counterclockwise have right-leading threading
DANGER
To avoid bodily injury or death from unexpected start-up or fall of a raised machine, stop engine, remove key, and
engage windrower lift cylinder safety props before going under machine for any reason.
CAUTION
Discblades have two sharp cutting edges that can cause serious injury. Exercise caution and wear gloves when working
with blades.
