Punching without a template
1.
Place the center-marked rail in the punch’s working area.
2.
Lift the rail and align the center mark with the back center of the top tool and hold.
3.
Straighten the rail so that it is parallel to the bottom tool’s surface. Activate the foot switch on the
hydraulic unit (punching).
4.
Release the foot switch immediately after the hole has been punched. This will prevent an
unnecessary heating of the hydraulic oil.
Holding down appliance-stripper
The punch is equipped with a holding down appliance. The holding down appliance pad also functions
as a stripper when flat bars of over 40 mm (15/8") width are being worked.
For flat bars with a width of less than 40 mm (15/8") and for lamellar copper, we offer auxiliary strippers
in addition to round tools.
Each upper tool has an auxiliary stripper of its own in a diameter range from 5 to 7,9 mm.
In a diameter range of 8 to 14 mm, (

" to

") one auxiliary stripper is sufficient for all upper tools.
ATTENTION !
When subsequently ordering upper tools, it is absolutely necessary to state that
the upper tool is used in conjunction with the auxiliary stripper.
Intermediate sizes, e.g. D 5.2 mm, (
3
/

") on request.
Long upper tool (bare)
The metallically bare upper tools may only be used in conjunction with the auxiliary strippers (26).
These upper tools are longer than the black standard upper tools. When using the bare upper tools
– without auxiliary strippers – the workpiece will stick to the upper tool - will not be stripped off R I S K

Prior to punching, it is absolutely necessary to strip the material. The material thickness without
insulation may amount to max. 10 mm.
