SPECIFICATIONS
Voltage: 120 volts AC, 60Hz.
Current rating: 3.5 amps
No load speed: 1800 rpm
Max shear thickness: 18Gauge
OPERATING PROCEDURES
1. Following all safety requirements already listed, plug the Power Cord (54) into a circuit-breaker protected
120 V~, 60 Hz power outlet.
warninG: do not turn on the tool until you have read this entire manual, and follow all safety
information, notes, cautions and warnings provided.
2. To turn on the tool, slide the Power Switch (38) forward to the ON position. The Upper Shear Blade (12)
will begin to move up and down at high speed.
nOte: It is a good idea to make a few practice cuts on scrap material before cutting your work piece.
3. To cut material, fit the Tool Rest (1) over the edge of the material, and move the tool slowly forward
along the desired cut line of the material. As the Upper Shear Blade (12) moves up and down against
the Lower Shear Blade (2), the material will be cut.
warninG: the edge of sheet metal is very sharp. always wear protective gloves when
handling sheet metal.
cautiOn: Do not cut across a welded seam as this might damage the blades.
4. To stop cutting, slide the Power Switch (38) back to the OFF position. Unplug the tool.
adjusting the cutting blades.
If the tool is operating properly, but is not cutting satisfactorily, you may have to adjust the blades.
1. Before attempting adjustment, unplug the tool.
2. Using a probe through the motor vents in the side of the Cover (48), turn the fan until the cutting blades
are open to the maximum amount. You can measure the gap between the blades using an automotive
feeler gauge (not included).
3. To determine the best spacing, use the formula: Distance in
mm (L) = 0.2 x thickness of thin steel plate in mm. (This is
the same as the gap being equal to the material thickness
divided by 5.) For example, a thin steel plate which is 1 mm
thick should be cut with a shear blade setting of .2 mm. This
assumes a hardness of the material at 390N/mm. For softer
material, reduce the gap. For harder material, increase the
gap.
