Sharpening the Blades
WARNING
When sharpening blade, pieces of blade could be
thrown and cause serious injury.
Wear proper eye protection when sharpening blade.
1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 95).
Note: Maintain the original angle. The blade retains
its balance if the same amount of material is removed
from both cutting edges.
1. Sharpen at original angle
2. Check the balance of the blade by putting it on a blade
balancer (Figure 96). If the blade stays in a horizontal
position, the blade is balanced and can be used. If the
blade is not balanced, file some metal off the end of the
sail area only (Figure 97).

ensure proper cutting.

cone must be installed toward the bolt head (Figure 97).
