The use of a residual current device with a rated
residual current of 30mA or less at all times is
recommended.
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. 3.
To facilitate smooth cutting of thick panels, if the cut-off
side goes toward the left, (Fig. 3) 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. 4. 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.
4. Inspecting the carbon brushes (Fig. 5)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with a new one having the same carbon
brush No. shown in the figure when it becomes
worn to or near the "wear limit". In addition, always
keep carbon brushes clean and ensure that they
slide freely within the brush holders.
5. Replacing carbon brushes
Disassemble the brush cap with a screwdriver. The
carbon brush can then be easily removed.
