Checking the Top Grind Angle
2
The angle that you use to grind your bedknives is very
important.
Use the angle indicator (Toro Part No. 131-6828) and the
angle-indicator mount (Toro Part No. 131-6829) to check
the angle that your grinder produces and then correct for
any grinder inaccuracy.
1. Place the angle indicator on the bottom side of the
bedknife as shown in
1. Bedknife (vertical)
2. Press the Alt Zero button on the angle indicator.
3. Place the angle-indicator mount on the edge of the
bedknife so that the edge of the magnet is mated with
the edge of the bedknife
Note: The digital display should be visible from the
same side during this step as it was in step 1.
