Maintenance and Service
Maintenance and Cleaning
f Before any work on the machine itself, pull
the mains plug.
f For safe and proper working, always keep
the machine and ventilation slots clean.
Clean and lubricate the punch 10, die 14 and
guide plate 11 every 3 operating hours.
Change the punch, die and guide plate in good
time when worn. Only sharp tools produce a
good cutting quality and make the machine last
longer.
Changing the Die
Loosen and remove both screws 9. Insert a new
die and tighten it firmly with the screws 9.
A worn die must not be reground.
Changing the Guide Plate
The guide plate 11 is used to protect the die
holder 15.
To change the guide plate, remove the die 14
(refer to “Changing the Die”). Loosen and re-
move the screws 13 on the hold down guide.
Remove the hold down guide 12 and the guide
plate 11.
Insert a new guide plate. Attach the die with the
screws 9 and the hold down guide via the
screws 13. Tighten the screws.
Changing the Punch
Insert the allen key 4 into the screw head of the
punch adjustment screw 16. Turn the adjust-
ment screw until it 7 is exact centre of the bore-
hole 8 at the die holder. Remove the allen key
from the punch adjustment screw 16.
Remove the die 14 (refer to “Changing the Die”
as well as the hold down guide 12 and the guide
plate 11 (refer to “Changing the Guide Plate”).
Loosen the screw 7 of the punch fastener and
pull out the punch 10 downward. Lubricate the
new or the reground punch properly and insert
it from underneath. Tighten the screw 7 again.
Attach the guide plate 11 and the hold down
guide 12 as well as the die 14 (refer to “Changing
the Guide Plate” as well as “Changing the Die”).
Regrinding the Punch
In most cases, regrinding the punch in good
time (e.g. with a diamond disc) can usually pre-
vent the punch from breaking out. Heavily dam-
aged punches may not be reground.
The punch may not be reground by more than
1 mm. Grinding may be carried out only along-
side the cutting surface and at exactly 90° to
the centre axis.
Set a light edge to the cutting edge of the punch
using a fine whetstone.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article
number given on the type plate of the machine.
