7.3C BLADE REPLACEMENT
The lower blades are symmetrical and can be rotated to expose four cutting edges.
The upper blades have two cutting edges.
TO ROTATE OR REPLACE THE BLADES, USE THE FOLLOWING STEPS:
⌦
CAUTION: THE UPPER CASTING OF THE NOTCHER IS HEAVY ENOUGH TO CAUSE
INJURY IF DROPPED. USE CARE WHEN HANDLING THIS TOOL.
1. Remove the return springs from the unit.
2. Rotate or replace the upper blade and snug bolts only, to allow further adjustments.
3. Rotate or replace the lower blades.
4. Lower the upper blade down until it just passes the lower blade, approximately 1/16 of an inch
(1.5mm).
5. Adjust the upper blade until the point almost touches the lower blades.
6. Center the rear of the upper blade with the rear of the lower blades. There should be a clearance
of approximately.005 of an inch (.12mm) on each side.
7. Tighten the upper blade bolts. To check blade alignment, raise and lower the upper casting
several times, by hand. After alignment, tighten the back up set screws, making sure that the
upper blade does not move.
