FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before adjusting or checking function
on the tool.
Permissible cutting thickness
Fig.1
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.
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

Switch action
Fig.2
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.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the
tool.
Punch replacement
Fig.3
Fit the wrench provided onto the lock nut and tap the
handle lightly with a hammer to loosen the lock nut.
Take off the die holder and use a wrench to remove the
screw. Then remove the punch.
Fig.4
To install the punch, insert it into the punch holder with
its cutting edge facing forward so that the pin in the
punch holder fits into the groove in the punch. Install the
screw and lock nut. Then tighten them securely.

OPERATION

CAUTION:
Hold the tool firmly with one hand on the main
•
handle when performing the tool.
Pre-lubrication
Coat the cutting line with machine oil to increase the
punch and die service life. This is particularly important
ga when cutting aluminum.

Smooth cutting is achieved by holding the tool upright
and applying gentle pressure in the cutting direction.
Apply tool oil to the punch about every 10 meters of mild
steel or stainless steel to be cut. Light oil or kerosene
should be used to keep an aluminum lubricated
continuously. Failure to lubricate aluminum in the cut will
cause chips to adhere to the tool, dulling the die and
punch and increasing load on the motor.
Cutouts
Fig.7
Cutouts can be done by first opening a round hole of
about 42 mm diameter or more in the material.
Cutting stainless steel
Fig.8
There is more vibration when cutting stainless steel than
mild steel. Less vibration and better cutting is possible
by adding another washer (standard equipment)
beneath the die.
Use the hex wrench provided to remove the two screws
and insert the washer below the die. Replace screws
and tighten securely.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may result.
The tool and its air vents have to be kept clean.
Regularly clean the tool's air vents or whenever the
vents start to become obstructed.
