The use of a residual current device with a rated
residual current of 30mA or less at all times is
recommended.
CUTTING
CAUTION
Never try to cut materials that are too large for the
capacity of the machine since this may cause
damage.
Applying cutting oil (spindle oil, machine oil, and
so on) along the shearing line may decrease wear
of the punch and die.
Use care to prevent cutting oil adhering to the
housing since the surface may be damaged.
The cutting directions of Punch shape (I) (see Fig.
4) are in the 3 directions of A, B and C (see Fig.
1) and these directions can be changed, but punch
shape (II) can be cut in direction B only.
1. Cutting plates
As shown in Fig. 5, hold the plates being cut parallel
with the machine and apply a light force while
cutting. When pocket cutting, make a hole 23 mm
in diameter or larger, as shown in Fig. 6, and start
cutting with the tip of the die holder.

2. Cutting corrugated and trapezoidal plates
(1) The cutting direction of this machine can be rotated
in 90° increments in 3 directions (A, B and C) (see
Fig. 1) by loosening the M8 hexagon socket set
screw mounting the die holder. Set the cutting
direction in the B or C direction to cut trapezoidal
plates. After that, securely tighten the M8 hexagon
socket set screw.
(2) Grip the machine firmly with both hands as shown
in Fig. 7, align with the shape of the trapezoidal
plate, push the machine forward until the die holder
is at right angles as shown in Fig. 8 and make the
cut.
REPLACING PUNCH AND DIE
CAUTION
In this case, be sure to previously disconnect the
plug from the power supply.
1. Service Life of the Punch and Die
Wear and damage to the cutting edges of the punch
and die can greatly influence the cutting operation.
Under normal usage, the service life of the punch
and die is as shown in the table below. Replace
the punch and die promptly when the end of the
service life approaches. The punch and die should
be replaced at the same time.
