HOW TO USE SHEAR
Model 6602:
Be sure the material to be sheared is firmly supported. Clamping is recommended to insure control of the tool and the workpiece. Place side knives of shear slightly on the edge of the top side of the workpiece to steady tool. Squeeze the trigger switch and guide shear into work. The tool cuts freely with only slight pressure. Forcing the tool will not make it cut faster. Always use sharp cutters. A light coat of suitable cutting fluid applied along the line of cut will increase cutter life.

Model 6604:
Be sure the material to be sheared is firmly supported. Clamping is recommended to insure control of the tool and the workpiece. The material to be cut should be positioned with the hidden or back surface of the material facing up to reduce marring of the exposed side. To achieve maximum cutting efficiency the bottom of stationary blades should be held parallel to and against the material being cut.
REPLACING CUTTERS
Replacement cutters are installed as follows:
CAUTION: DISCONNECT TOOL FROM POWER SOURCE.
REMOVE CUTTER BLADES (see Fig. 3):
1.Remove shear head from motor unit: B loosen three cap screws (A) and pull cutter head forward (a light twisting motion may be helpful), to separate it from motor unit.
2. Remove the three cap screws (A) from | A | E | |
the shear housing (do not lose spacer |
|
| |
bushing (C) from the middle cap screw). |
|
| |
3. Remove the center blade by gently | C |
| |
tapping it rearward (do not lose spacer | F | ||
| |||
bushing (C) from hole in center blade). |
| ||
|
| ||
4. The side knives (D) and (E) will now |
|
| |
drop out of the shear housing. |

Note: For Model 6604 change side
knives after they show a wear pattern of fifty percent (50%) in width.They can be swapped left to right and used until the patterns meet. When the patterns meet, the left and right side knives can be inverted and used until they show a wear pattern of fifty percent (50%) in width, and then they can be swapped from left to right until all four (4) sides of the blades are used. 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 will cause overloading to the power unit.
