Firmly support and clamp the workpiece to ensure control. Position the workpiece

with the hidden or back surface of the material facing up to reduce marring of the

exposed side. To achieve maximum cutting efficiency, hold the bottom of the

stationary blades parallel to and against the workpiece.

HOW TO USE THE SHEAR

TO REMOVE THE CUTTER BLADES

Disconnect the tool from the power source!

1. Remove the shear head from the

motor unit. Loosen the three cap

screws (A) Fig. 3. Pull the cutter

head forward to separate it from

motor unit. A light twisting motion

may be helpful.

2. Remove the three cap screws (A)

from the shear housing. Retain the

spacer bushing (C) with the middle

cap screw).

3. Remove the center blade by gently

tapping it rearward. Retain the

spacer bushing (C) removed from

the hole in the center blade.

4. The side knives (D) and (E) will drop

out of the shear housing.

Fig. 3

NOTE: 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 to do so will overload the power unit.

TO INSTALL THE CUTTER BLADES

Disconnect the tool from the power source!

1. Place the side knives (D) and (E) Fig. 3 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). Thread the screw into the

housing one or two turns. DO NOT TIGHTEN.

2. Coat the remaining spacer bushing (C) Fig. 3 with lubricant and insert it into the

hole in the center blade (F). Start the center blade (with the spacer bushing) into

the rear of the shear housing. 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).

5. 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.
