Inspecting the Blades

Service Interval: Before each use or daily
1. Inspect the cutting edges (Figure 53). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.
2. Inspect the blades, especially the curved area
(Figure 53). If you notice any damage, wear, or a slot
forming in this area (Figure 53), immediately install a
new blade.

the blade is bent and must be replaced; refer to
