Switch action
For tools with pivot type lock-off lever
(Fig. 7 & 8)
CAUTION:
• Before plugging in the tool, always check to see that
the paddle switch actuates properly and returns to the
“OFF” position when released.
• The switch lever does not actuate when the lock-off
lever is in the LOCK position. Do not try to actuate the
switch lever when the lock-off lever is in the LOCK posi-
tion.
• When not operating the tool, keep the lock-off lever in
the LOCK position.
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.
For tools with slide type lock-off lever (Fig. 9)
CAUTION:
Before plugging in the tool, always check to see that the
paddle switch actuates properly and returns to the “OFF”
position when released.
To prevent the switch from being accidentally actuated, a
lock-off lever is provided. To start the tool, slide the lock-
off lever in the direction of the arrow and squeeze the
switch lever. Release the switch lever to stop.
Permissible shearing thickness (Fig. 10)
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.
Holding material (Fig. 11)
The materials for cutting should be fastened to the work bench by means of workholders.
Shearing method (Fig. 12)
Keep the shear moving parallel with the material.
Maximum cutting width
Stay within the specified maximum cutting width (A): Case of length 1,800 mm.
Minimum cutting radius
Minimum cutting radius is 30 mm when cutting 1.0 mm mild steel.
