APPLICATIONS
For shearing steel plate, brass plate, copper plate,
aluminum plate, stainless steel plate, tin plate, and
other metal plates, also leather and fiberboard.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, which could cause
a serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Adjusting the horizontal gap between the shearing
blades
Adjust the horizontal gap between the shearing
blades (A in Fig. 2) at approximately 1/10 the steel
plate thickness to be sheared, according to the
following procedures. (Fig. 3)
(1) Loosen the hexagonal socket bolts fastening the
stationary blade. Loosen the M4 lock nut, and push
back the M4 slotted set screws slightly.
(2) From the supplied thickness gauges, select one that
is 1/10 the thickness of the panel to be cut. Thickness
of each thickness gauge is marked thereon. Insert
the gauge in between the blades, then tighten the
hexagonal socket bolts very loosely. Next, use a
screwdriver to turn the M4 slotted set screws to
position the stationary blade until it hits the thickness
gauge.
(3) If the space between blades is larger than the
thickness of the panel to be cut, there will be burrs
for a less than clean cut.

If the space between blades is too narrow, cutting
speed will be affected. For cutting in a curved line,
making the space a little bigger will make the cutting
easier.
(4) After adjustment, tighten the M4 nuts securely so
they will not loosen during operation.
(5) Securely tighten the hexagonal socket bolts fastening
the stationary blade.
CUTTING
CAUTION
Do not attempt to cut panels of thicknesses that
are beyond the capability of the hand shear. Doing
so will result in premature breakage of the hand
shear.
Perform the cutting operation only after the panel
is fixed securely.
When cutting thin panels, level the unit horizontally, as
shown in Fig. 4.
To facilitate smooth cutting of thick panels, if the cut-off
side goes toward the left, (Fig. 4) raise the rear of the unit
slightly. And if the cut-off side goes toward the right,
lower the rear of the unit slightly.
BLADE REPLACEMENT
The hand shear uses disposable blades. Each blade has 8
cutting edges, as shown in Fig. 5. After a cutting edge cuts
400 meters of panel, cutting performance will fall. Then
use another cutting edge. After all 8 cutting edges are
used and worn, replace the blade.
MAINTENANCE AND INSPECTION
1. Inspecting the blade
Using a worn or chipped blade will put an excessive
burden on the motor and affect work performance.
Therefore, always use a well-cutting blade.
2. Inspecting the mounting screws:
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
