3 Assembly
3.1 Mount handle
Remove
two hex head bolts #15 from pivot arm #12. Mount handle #13 into groove
on pivot arm. Secure handle with hex head bolts. Tighten bolts securely.
3.2 Mount hold-down plate
Insert threaded rod of hold-down plate #1 through hole in support block #4.
3.3 Installation
Machine should be installed on a level surface, with proper lighting. Machine can
be floor-mounted, stand-mounted or bench-mounted. Be sure to provide clearance
for handle bar rotation. Use four mounting holes on the base to bolt machine
securely to floor, bench or stand (fasteners not included).
Area around machine should be clear of scraps, oil or dirt. Apply a suitable non-
skid material to floor.
4 Operation
Rotating handle #13 operates the shear. Be sure to keep hands clear of shear
when rotating handle. The maximum capacity of the machines is ¼” mild steel.
4.1 Shearing plate and flat bars
1.
Adjust hold-down plate #1 so that workpiece can lie horizontally between shear
blades. Place workpiece between blades #7 and #20 and underneath hold-down
plate. Adjust hold-down plate to be positioned at the top surface of the workpiece,
with the workpiece held horizontally. Secure the hold-down plate in position by
tightening it.
2.
Support workpiece between blades and underneath the hold down plate at
position where cut is desired. Pull handles #13 forward with both hands until
blade cuts through workpiece.
CAUTION!
Do not reach in back of shear to grasp fall out piece.
Shear thicker material is done by “snapping” crank handles so that upper blade
impacts workpiece.
Upper blade is mounted at an angle so that workpiece can be sheared in small
increments. To minimize distortion, approximately 5/8” of workpiece should be
sheared with each impact.
4.2 Shearing round bars
Round bars up to 7/16” diameter can be cut with shear HS-5 / 6.
Round bars up to 1/2” diameter can be cut with shear HS-8 / 10 / 12.
Place bar through holes in face of upper blade #7 and die #10. Position bar
where cut is desired and pull handle #13 forward until bar is cut.
