INSTRUCTIONS FOR USE
The power shear (based on the Makita Model JS 1660) provides a
means for cutting sheetmetal in such a way that very little distortion
is left in the workpiece. This is possible because the shear removes a
waste strip, about 4 mm wide, and most of the distortion inherent in
shearing sheetmetal goes into this waste strip. For use with a
Magnabend the shear has been fitted with a special magnetic guide.
The shear works well in combination with a Magnabend Sheetmetal
Folder; the Magnabend provides both a means of holding the
workpiece fixed while being cut and also a means for guiding the tool
so that very straight cutting is possible. Cuts of any length can be
handled in steel up to 1.6 mm thick or aluminium up to 2 mm thick.
To use the tool first place the sheetmetal workpiece under the
clampbar of the Magnabend and position it so that the cutting line is
exactly 1 mm in front of the edge of the Bending Beam.
A toggle switch labelled “NORMAL / AUX CLAMP” will be found
next to the main ON/OFF switch. Switch this to the AUX CLAMP
position to hold the workpiece firmly in position.
Position the shear at the right-hand end of the Magnabend and ensure
that the magnetic guide attachment engages on the front edge of the
Bending Beam. Start the power shear and then push it evenly along
until the cut is completed.
Notes:
1. For optimum performance the blade clearance should be adjusted
to suit the thickness of material to be cut. Please read the Makita
instructions supplied with the JS1660 shear.
2. If the Shear does not cut freely check that the blades are sharp.

Note that the waste strip
curls out in a continuous
spiral leaving your
workpiece distortion-free.
