NOTE: Always replace or sharpen both blades at the same time.
1.Inspect blade pin (12) for nicks or gouges, and if you find any, replace the blade pin.
2.Insert blade pin through the blade (9). Blade should swivel on blade pin; if it doesn’t, determine the cause and correct.
3.Align crossbar (8) with blade access hole in cutter frame. Apply a liberal coating of Never Seez or equivalent to blade pin and crossbar hole. Make sure blade offset is away from cutter. Push blade pin through crossbar. Pin should rotate freely prior to installing blade clip (15).
4.Install shims (13 & 16) over blade pin.
NOTE: Only use enough shims to allow keyhole plate (14) to slide into blade pin groove.
5.Install blade clip (15) over keyhole plate and into blade pin groove.
6.Secure into position with cap screw (35). Torque cap screw to 85
7.Repeat steps for opposite side.
NOTE: Blade should be snug but should swivel on pin without having to exert excessive force. Keep any spacers not used in the installation as replace- ments or for future installation.
Sharpening Blades
NOTICE
■When sharpening blades, grind the same amount on each blade to maintain balance. Replace blades in pairs. Unbalanced blades will cause excessive vibration, which can damage gearbox bearings. Vibration may also cause struc- tural cracks to cutter.
1.Sharpen both blades at the same time to maintain balance. Follow original sharpening pattern.
2.Do not sharpen blade to a razor
3.Do not sharpen back side of blade.
