Front Circular Blade Adjustment
Tools and Supplies needed:
1/2" Breaker Bar and 3/4" Socket
9/16" Wrench
Leather Gloves
1.
Loosen the Coupling Nuts at the center of each circular Blade with a 1/2"
Breaker Bar and 3/4" Socket (Figure 22).
Note: Keep the spaces between the circular Blades and rear Blade the same on both
sides of rear Blade when adjusting in next step.
2.
Loosen the Jam Nuts and adjust the Bolts with two 9/16" Wrenches so the
two Circular Blades are close enough together that a piece of paper can be
dragged through with some resistance but without ripping or being cut.
3.
When adjustment is accurate, firmly tighten the two Coupling Nuts using a
1/2" Breaker Bar and 3/4" Socket.
4.
Tighten the Jam Nuts against the Frame to hold the end of the Bolt against
the Adjustment Pin Bushings.
Note: The two Circular Blades must rotate. Make sure that the Blades are not
obstructed and are rotating on the Bushings.
