Sharpening the Blades

1. Remove the blades. See Replacing The Blade in the Product Care Section.
2. Clean any debris from the blades. Keep blades sharp and free of build up at all times.
3. To properly sharpen the cutting blades, remove equal amounts of metal from both
ends of the blades along the cutting edges, parallel to the trailing edge, at a 25°-
30° angle. Always grind each cutting blade edge equally to maintain proper blade
balance. See Figure 43.
WARNING: If a blade is bent or otherwise damaged, replace the blade with a
new one. Use only original equipment blades.
WARNING: A poorly balanced blade will cause excessive vibration, may
damage the machine and/or result in personal injury.
4. Test the blade's balance using a blade balancer. Grind metal from the heavy side until
it balances evenly.
5. Reinstall the blades. See Replacing The Blade in the Product Care Section.
