Lubricating/cooling the punch
To extend the service life of the punch (6), a lubricating
agent with good cooling properties (e.g. cutting oil) should
be used.
Apply a line of lubricant to the top side of the metal sheet
along the intended cutting line.
Cutting along a cutting mark or with a guide
Straight cuts are carried out easier when the power tool is
guided alongside a rule.
Contours can be cut by guiding the power tool along a tem-
plate.
For inside cuts, a hole with a diameter of 21 mm must be
pre-drilled.

Maintenance and Service

Maintenance and Cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
Clean and lubricate the punch (6) and die (7) every three
operating hours.
Change the punch and die in good time when worn. Only
sharp tools produce a good cutting quality and make the
power tool last longer.
The punch (6) and the die (7) may not be resharpened.
Changing the die
Unscrew the knurled screw (9) from the die holder (5). Take
out the die (7).
If necessary, clean the die holder (5). Put a new, well
greased die (7) into the die holder. Pay attention to the
alignment of the flat side.
Screw back on the knurled screw (9) with the rubber
ring (8) attached. Use a hex key to tighten the screw against
the resistance of the rubber ring (3–4 Nm).
Changing the punch
Loosen the die holder screw (2) and pull the die holder (5)
completely out of the housing.
Slide the punch (6) sideways out of the mounting and pull it
out in a downward motion.
Put a new, well greased punch (6) in the groove of the
mounting and centre it.
