Installing the Inner Blade Collar

are perfectly clean and free of burrs or indentations. Clean and repair as
necessary
2. Ensure that the Drive Key is in place.
3. Slide the Inner Collar onto the tapered portion of the Blade Shaft

Collar and Shaft from mating properly.

• Tighten with a ½” impact wrench to seat the tapered surfaces of the Inner
Collar and Blade Shaft.
