220E BLADES
BLADE SHARPENING
Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed. In use, blades develop a
back-bevel (See Figure A). When re-sharpening, blade will not be truly sharp until all back-bevel
is gone.
Note:
Thinner blades are easier to sharpen, but they also break easier.
• Always wear gloves and safety glasses.
• Grind blade using a 4" diameter disk with 120 or finer grit. Be careful not to catch disk on edge or
corner of blade.
• Pass grinder back and forth along blade edge being careful to hold grinder at proper angle of blade.
Grind until sharp.
• Using a good quality fine tooth hand file, use same procedure as above.
• Blades are sharp. Use extreme caution.
• Have plenty of sharp blades on each job so on-the-job blade sharpening is eliminated.
• It is best to resharpen dull blades on proper bench or belt grinder in the shop, so the blades are ready
for the next job.
SELF SCORING BLADE SHARPENING
It is important to keep the “wings” on a self scoring blade sharp (See Figure B). Use a file on the “wing”
edge. Sharpen the flat part of the blade, the same way as described above.
CARBIDE TIPPED BLADE SHARPENING
To sharpen carbide tipped blades, a wheel to grind carbide is necessary, ie: green wheel or diamond
wheel.

CAUTION:
Blades are sharp, use extreme caution.
CAUTION:
Never change cutting head or service
blades while machine is running.
WARNING:
Disarm machine when machine is not in
use. Remove the cutting head or drop cutting head to the
floor. Failure to do so could cause severe bodily injury.
