BLADE SERVICING

blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out when
sharpening.
Use only original equipment blades on this cutter. They are made of special heat-treated alloy steel. Substitute
blades may not meet specification and may fail in a hazardous manner that could cause injury.
BLADE SHARPENING
Always sharpen both cutting edges of each blade at the same time, the same amount, to maintain balance. Follow
original sharpening pattern as shown. Do not sharpen blade to a razor edge, but leave a 1/32" blunt edge. Do
not shapen back side of blade. Figure 6.
WARNING! Avoid personal injury. Always block the cutter up to prevent it from falling when the blades and/
or carrier are being serviced.
