FUNCTIONAL DESCRIPTION
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before adjusting or checking function
on the tool.
Changing the die position
Fig.1
The die position can be changed 360°. To change it,
proceed as follows.
1.
Loosen the lock nut with the wrench provided.
2. Pull the die holder slightly and turn it to the
desired position for operation.
3.
Tighten the lock nut to secure the die holder in
the desired position.
There are four positive stops at 90° each: 0°, 90° left
and right and 180°. To position the die to any of these
positive stops:
1.
Loosen the lock nut with the wrench provided.
2. Pull the die holder slightly and depress lightly
while turning it to the desired position. The die
holder will lock into one of the positive stop
positions as desired.
3.
Turn the die holder slightly to make sure that it is
positively locked into position.
4.
Tighten the lock nut to secure the die holder.
Permissible cutting thickness
Fig.2
The thickness of material to be cut depends upon the
tensile strength of the material itself. The groove on the
die holder acts as a thickness gauge for allowable
cutting thickness. Do not attempt to cut any material
which will not fit into this groove.
Cutting line
The notch in the die holder indicates your cutting line.
Its width is equal to the cutting width. Align the notch to
the cutting line on the workpiece when cutting.
Switch action
Fig.3
CAUTION:
•
Before plugging in the tool, always check to see
that the switch actuates properly and returns to the
"OFF" position when the rear of the switch lever is
depressed.
To switch on, depress the rear of the switch lever and
push it forward. Then depress the front of the switch
lever to lock it.
To switch off, depress the rear of the switch lever.
ASSEMBLY
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Removing or installing the punch and die
Fig.4
Always replace the punch and die as a set. To remove
the punch and die, loosen the lock nut with the wrench.
Remove the die holder from the tool. Use the hex
wrench to loosen the bolts which secure the die.
Remove the die from the die holder.
Use the hex wrench to loosen the screw which secures
the punch. Pull the punch out of the punch holder.
Fig.5
To install the punch and die, insert the punch into the
punch holder so that the notch in the punch faces toward
the screw. Tighten the screw to secure the punch. Install
the die on the die holder. Tighten the bolts to secure the die.
Fig.6
Then install the die holder on the tool so that the punch
is inserted through the hole in the die holder. Tighten the
lock nut to secure the die holder. After replacing the
punch and die, lubricate them with machine oil and run
the tool for a while.

OPERATION
Pre-lubrication
Coat the cutting line with machine oil to increase the
punch and die service life. This is particularly important
when cutting aluminum.
Cutting method
Fig.8
Hold the tool so that the cutting head is at a right angle
(90°) to the workpiece being cut. Move the tool gently in
the cutting direction.
Cutouts
Fig.9
Cutouts can be done by first opening a round hole over 21
mm in diameter which the cutting head can be inserted into.
Cutting the corrugated or trapezoidal sheet
metals
Fig.10
Set the die position so that the die faces the cutting
direction either when cutting at an angle or perpendicular
go grooves in corrugated or trapezoidal sheet metals.
Always hold the tool body parallel to the grooves with
the cutting head at a right angle (90°) to the cutting
surface as shown in the figure.
