DANGER
POTENTIAL HAZARD
♦A worn or damaged blade can break.
WHAT CAN HAPPEN
♦A piece of the blade could be thrown into the operator’s or bystander’s area, resulting in serious personal injury or death.
HOW TO AVOID THE HAZARD
♦Inspect the blade periodically for wear or damage.
♦Replace a worn or damaged blade.
If it is necessary to remove the blade for replacement or sharpening, complete the following steps:
f)Remove the blade. Make sure to grasp the end of the blade using a rag or a thickly padded glove. Place a wrench on the top spindle nut and remove the blade bolt (Figure 16).
FIGURE 16
g)For Sharpening: File the top side of the blade to maintain its original cutting angle (Figure 17A) and inner cutting edge radius (Figure 17B). The blade will remain balanced if you remove the same amount of material from both cutting edges.

h)Check the balance of the blade by placing the center hole of the blade over a nail or screwdriver shank clamped horizontally in a vise (Figure 18). If either end of the blade rotates downward, file that end (not the cutting edge). The blade is properly balanced when neither end drops.
