Introduction
These bench-mounted plate shears are designed
to cut flat (sheet/plate) stock and round (bar)
stock of ferrous and non-ferrous metals, and even
plastics. They are simple to use and excel at
making quick, clean cuts for rough cutouts. Each
model features ground-and-hardened replaceable blades, an extra-long leverage-maximizing
handle, and a spring-assisted material hold-down.

Figure 2. Attaching handle to shear.
2. Place shear on a workbench. Use mount-
ing holes in base as a guide for drilling and
attaching shear. This will prevent it from moving during operation and reduce the risk of
accidental injury or damage.

Another option is a "direct mount" (see example
below) where the machine is secured directly to
the workbench with lag screws and washers.
The base of this machine has mounting holes
that allow it to be fastened to a workbench or
other mounting surface to prevent it from moving
during operation and causing accidental injury or
damage.
The strongest mounting option is a "Through
Mount" (see example below) where holes are
drilled all the way through the workbench—and
hex bolts, washers, and hex nuts are used to
secure the machine in place.

2. Place workpiece between blades or through
shearing port.
— If shearing flat workpiece, position and
secure hold-down so it firmly presses
workpiece against lower blade.
3. Using slow and even pressure, pull handle
down to cut workpiece.
Note: If material seems too thick or too hard,
do not force shear! Instead, use metal-cutting
bandsaw or other tool to cut workpiece.
Maintenance
• Always keep blades lubricated with light oil.
• Keep pivot points tight.
• Check all shear hardware before every use
for loose or worn components.
AMPUTAT I ON HAZ ARD !
To reduce risk of serious personal injury:
• Keep fingers, hands, and all body parts
away from blades and cutting area during
use.
• Prevent unauthorized use by children or untrained users. Keep children
and bystanders at safe distance while
shearing.
