accessory or attachment.

WARNING: Cut Hazard. Wear gloves when handling
sheet metal. The edges are sharp and can cause serious
personal injury.
For accurate work, always clamp or anchor the material to
be cut. Line up one edge of the tool's middle blade with the
cutting line and advance blades into the material without forced
effort or unnecessary pressure. A little practice will enable you
to determine what forward pressure gives you the smoothest
cutting. It is important to keep the lower surfaces of the side
blades flat on the material being cut. When cutting curves, do
not tilt the tool; keep the side blades flat and level.The head of
the shear will swivel to afford better access to the material. For
best cutting efficiency, keep blades sharp.
