Checking Cutters
Inserts and cutter tips should be replaced or turned when worn or damaged. Excessive wear
causes damage to the cutter head and requires the machine to use excessive horsepower. A
dull edge on the tips exists when a fine line, approximately .005” runs along the cutting edge.
Note: If cutter heads are not easily reached after removing guards, use the hand crank to
move them outward for easier access.
Proper tip maintenance will give you many years of satisfactory service. Factors that reduce
tip life include:
Hitting metal embedded in the wood being notched
High feed speeds
Frozen lumber
Frequency of changing worn inserts
Cutter Inserts
Note:
Do not attempt to sharpen cutter inserts. Grinding carbide is hazardous to your health.
Rotate the 2-sided carbide insert whenever it becomes dull or approximately every 2 weeks,
depending on the quantity and type of wood being processed.
The radius end cutter disc (round) insert should also be rotated approximately 1/3 turn every
2 weeks also. The radius end cutter disc insert has bluing for better placement and maximum
usage.
Replacing 2-sided Carbide Inserts
Turn machine off and lock-out / tag-out electrical panel.
Loosen socket head cap screw allowing
