OPERATION

WARNING: Cut Hazard. NEVER have any part of your body near the blades.
Serious personal injury may occur.
WARNING: Cut Hazard. To reduce the risk of serious personal injury, DO NOT
use the shear with any kind of 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
(Fig. 12). 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.

For best results, always clamp or anchor the material to be cut. Position the shear so
that the material is between the two jaws. It is best to practice using the tool on scrap
material in order to determine the best pressure and angle at which to hold the tool for
the application. When not cutting from the edge of the material, drilling a starter hole
should ease positioning of the shear. Wear gloves when handling sheet metal. The
edges are sharp and can cause injury.

Disassembly and Assembly

WARNING: Turn unit off and disconnect battery pack before installing and
removing accessories, before adjusting or when making repairs. To prevent
inadvertant operation, lock the trigger switch when the tool is not in use and when
