CAUTION:
Before plugging in the tool, always check to see
•
that the switch lever (paddle switch) actuates
properly and returns to the ''OFF'' position when
released.
The switch lever does not actuate when the lock-off

To prevent the switch from being accidentally actuated, a
lock-off lever is provided. To start the tool, turn the
lock-off lever to the FREE position and then squeeze the
switch lever. Release the switch lever to stop.

All manuals and user guides at all-guides.com
The groove on the yoke serves as a thickness gauge for
shearing mild or stainless steel plate. If the material fits
within the groove, it is shearable.
The thickness of materials to be sheared depends upon
the type (strength) of the material. The maximum
shearing thickness is indicated in the table below in
terms of various materials. Attempting to shear materials
thicker than indicated will result in tool breakdown and/or
possible injury. Keep within the thickness shown in the
table.

Blade inspection
Before using the tool, check the blades for wear. Dull,
worn blades will result in poor shearing action, and the
service life of the tool will be shortened.

Rotating or replacing blades

Both the upper and lower blades have four cutting edges
on each side (the front and back). When the cutting edge
becomes dull, rotate both the upper and the lower blades
90° to expose new cutting edges.
When all eight edges are dull on both the upper and
lower blades, replace both blades with new ones. Each
time blades are rotated or replaced, proceed as follows.
