Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
Clean and lubricate the punch 5 and die 4 every
3 operating hours.
Change the punch and die in good time when
worn. Only sharp tools produce a good cutting
quality and make the machine last longer.
The punch 5 and the die 4 may not be reground.
Changing the Die
When the die is locked, loosen the locking screw
3 (see "Locking/Loosening the Die", page 13).
Unscrew the screwed cap 2 using an open-end
spanner (size 30 mm). Pull the die 4 off.
Insert a new, well lubricated die 4. Tighten the
screw cap 2 again.
Changing the Punch
To change the punch 5, remove the die (see
"Changing the Die", page 14).
Unscrew the hollow screw 6 and remove the
punch 5.
Insert a new, well lubricated punch 5 and
tighten it with the hollow screw 6. Fasten the
die again (see "Changing the Die", page 14).
WARNING! Important instructions for con-
necting a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to
the following code:
Do not connect the blue or brown wire to the
earth terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it
must be disposed of safely.
