1/16" [1.5 mm]. See page 30.

1. Set grind selector to VARIABLE TORQUE RELIEF.
2. Set spin DRIVE ROTATION SWITCH to rotate the reel into the FIXED FINGER, counter-clockwise when
looking from the right. NOTE: relief torque reel rotation is always opposite spin rotation.
3. With the grinding head above the right-side TRAVEL LIMIT SENSOR, jog the grinding head up while
manually rotating the reel until the INDEX FINGER touches the blade.
NOTE: The INDEX FINGER position must be set to stop the reel blade and allow traversing to the left
without the blade hitting the side of the relief finger.
4. Turn the TRAVERSE SPEED KNOB to zero, then depress the TRAVERSE DRIVE MOTOR SWITCH to ON.
Using the TRAVERSE SPEED KNOB to slowly jog left until the reel blade is on the RELIEF FINGER.
NOTE: When the GRIND SELECTOR is set to VARIABLE TORQUE, the traverse will wait on the right TRAVEL
LIMIT SWITCH until the indexing finger proximity switch is activated. It will then start traversing to the left.
5. Depress the GRIND MOTOR SWITCH to ON.
6. Manually jog the traverse all the way to the left, watching for proper clearance between the grinding
wheel and the reel blade. Check for proper clearance between the INDEX FINGER (after releasing from
blade at far left position) and the front side of the blade on the return trip to the home position. Also
verify clearance with the reel blade support spiders.
7. Stop the traverse over the right-side Travel Limit Sensor and check for a proper blade index (the automatic
index feature will catch the next blade to be ground). Turn OFF the GRINDING MOTOR and TORQUE
SWITCHES.
