FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function
on the tool.
Switch action
► Fig.1: 1. Switch trigger 2. Lock button
CAUTION:
• Before plugging in the tool, always check to see
that the switch trigger actuates properly and
returns to the "OFF" position when released.
• Switch can be locked in "ON" position for ease
of operator comfort during extended use. Apply
caution when locking tool in "ON" position and
maintain firm grasp on tool.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
For continuous operation, pull the switch trigger and
then push in the lock button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Permissible shearing thickness
► Fig.2: 1. Gauge for stainless: 2.5 mm (3/32")
2. Gauge for mild steel: 3.2 mm (1/8")
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 in the table.
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
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
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.
The service life of the blades varies in terms of the
materials to be cut and the fixed blade clearance.
Roughly speaking, a blade can cut about 500 m of 3.2
mm mild steel with one cutting edge (total 2,000 m with
four cutting edges).
