Switch action (Fig. 6)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the "OFF"
position when released.
To start the tool, simply pull the trigger. Release the trig-
ger to stop. For continuous operation, pull the trigger and
then push in the lock button. To stop the tool from the
locked position, pull the trigger fully, then release it.
Permissible shearing thickness (Fig. 7)
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 shear-
ing 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 possi-
ble injury. Keep within the thickness shown below.
Max. cutting capacities
Steel up to 400 N/mm
Steel up to 600 N/mm
Steel up to 800 N/mm
Aluminum up to 200 N/mm
Holding material (Fig. 8)
The materials for cutting should be fastened to the work
bench by means of workholders.
Shearing method (Fig. 9)
For smooth cuts, tip the tool slightly backward while
advancing it.
