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
a
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.
