Servicing the Cutting Blades To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, keep extra blades on hand. Blade Safety A worn or damaged blade can break, and a piece of the blade could be thrown at you or bystanders, resulting in serious personal injury or death. Trying to repair a damaged blade may result in discontinued safety certification of the product. • Inspect the blade periodically for wear or damage.
Inspecting the Blades Service Interval: Before each use or daily 1. Inspect the cutting edges (Figure 106). 2. If the edges are not sharp or have nicks, remove and sharpen the blade; refer to Sharpening the Blades (page 77). 3. Inspect the blades, especially in the curved area. 4. If you notice any cracks, wear, or a slot forming in this area, immediately install a new blade (Figure 106). g000975 Figure 107 1. Measure here from blade to hard surface g006530 Figure 106 1.
