If the punch should become wedged during cutting, switch
the machine off, relubricate the punch and release the ten-
sion of the steel sheet. Do not exert force, otherwise the
punch and die will become damaged.
Maximum Steel Sheet Cutting Capacity
The maximum steel sheet cutting capacity d
max
depends on
the strength properties of the material to be cut.
The machine allows for straight and deformation-free cutting
of metal sheets to the following thicknesses:
Lubricating/Cooling the Punch
To extend the service life of the punch
5
, a lubricating agent
with good cooling properties (e.g. cutting oil) should be used.
Apply a trail of lubricant beads onto the top side of the metal
sheet alongside the intended cutting line. For long periods of
continual use or for work with high frictional wear (e.g. when
cutting aluminium), the cutting head should be immersed into
a container with lubricant in regular intervals.
Cutting along a Cutting Mark or with a Guide
Straight cuts are carried out easier when the machine is guid-
ed alongside a rule.
Contours can be cut by guiding the machine along a template.
For inside cuts, pre-drilling a hole with a diameter of 16 mm is
necessary.
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.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
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 ma-
chine 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 “Lock-
ing/Loosening the Die”, page 5).
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 6).
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 6).
