INSTALLING CUTTER BLADES

NOTE: For Model 6605, change the side knives after they show a width wear pattern of fifty percent (50%).Swap the knives left to right and use them until the patterns meet. When the patterns meet, invert the left and right side knives and use them until they show a width wear pattern of fifty percent (50%). They can then be swapped from left to right until you use all four (4) sides of the blades. Never exceed 10,000 feet of cutting on a set of side knives. The tool will continue to cut after these landmarks are reached, but the power unit will become overloaded.

1.Place the side knives (D) and (E) back into the shear housing. Insert a cap screw through the center hole in the shear housing, the side knife (E), the spacer bushing (C), the other side knife, (D), and then thread the screw into the housing one or two turns. DO NOT TIGHTEN.

2.Coat the remaining spacer bushing (C) with lubricant and insert into the hole in the center blade (F). Start the center blade (with spacer bushing) into the rear of the shear housing, and tap it forward until the hole in the spacer bushing aligns with the front hole in the shear housing. Insert a cap screw and thread it into the housing one or two turns. DO NOT TIGHTEN. Coat the center blade yoke area with lubricant.

3.Insert the remaining cap screw into the rear hole in the shear housing and thread it into housing one or two turns. DO NOT TIGHTEN.

4.Place the shear head on the motor unit. Seat it with a light twisting motion. Rotate the shear head to the desired position (any radial position), and tighten all three cap screws (A).

For Model 6603, tighten all three cap screws (A) to 30-35 in-lbs. Failure to tighten the cap screws properly can cause the cap screws (A) to break.

For Model 6605, tighten all three cap screws (A) to 45-50 in-lbs. Failure to tighten the cap screws properly can cause the cap screws (A) to break.
