Bosch Power Tools
The machine operates more quietly when it is raised slightly
during cutting. If the punch should become wedged during
cutting, switch the machine off, relubricate the punch and re-
lease the tension of the steel sheet. Do not exert force, other-
wise the punch and the 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 increase the service life of the punch
10
, you should use a
lubricant with good cooling function, e.g. cutting oil
2 607 001 409.
Apply a trail of lubricant beads onto the top side of the metal
sheet alongside the intended cutting line.
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 21 mm is
necessary.
Temperature Dependent Overload Protection
If used in accordance with its intended use, the power tool
cannot be overloaded. If the power tool is overloaded or not
kept within the permitted battery temperature range, the
stroke rate is reduced or the power tool switches off. When
the stroke rate is reduced, the power tool will not run at full
stroke rate again until the permitted battery temperature has
been reached. If it automatically shuts down, switch the pow-
er tool off, allow the battery to cool down, then switch the
power tool back on.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
For safe and proper working, always keep the machine
and ventilation slots clean.
Clean and lubricate the punch
10
and die
11
every 3 operat-
ing 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
10
and the die
11
may not be reground.
Changing the Die
Unscrew the knurled screw
13
of the die holder
9
. Take out
the die
11
.
Il necessary, clean the die holder
9
.
Put a new, well greased die
11
into the die holder. Pay atten-
tion to the alignment of the flat side.
Screw the knurled screw
13
with attached rubber ring
12
back on. Use a hex key to tighten the screw against the resist-
ance of the rubber ring (3–4 Nm).
Changing the Punch
Loosen the screw
4
and pull the die holder und
9
completely
out of the housing.
Slide the punch
10
sideways out of the mounting and pull it
out in a downward motion.
Put a new, well greased punch
10
in the groove of the mount-
ing and centre it.
Push the die holder
9
with caution over the punch
10
back
into the housing. Turn the die holder into one of the three pos-
sible positions (see “Changing the Cutting Direction”,
page 11). Tighten the screw
4
.
