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.

A cut-out within the perimeter of the workpiece may be produced by drilling

¼" diameter starting hole, then following directions above.

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:

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

the shear housing (do not lose spacer

bushing (C) from the middle cap screw).

3. Remove the center blade by gently

tapping it rearward (do not lose spacer

bushing (C) from hole in center blade).

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

drop out of the shear housing.

INSTALL CUTTER BLADES (see Fig. 3):

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.
