4. Inspect all parts; replace any parts that are damaged.
Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
each blade (Figure 30). Maintain the original angle.
The blade retains its balance if you remove the same
amount of material from both cutting edges.
1. Sharpen at original angle
2. Check the balance of each blade by putting it on
a blade balancer (Figure 31). 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
of the back side of the blade. Repeat this step until
the blade is balanced.
