scribed.
• The individual chapters have been
designated with a capital letter and
a symbol to facilitate the use of this

2. Explanation of symbols and signs
This exclamation mark an-
nounces an important com-
ment.

• Do not place hands or objects in dril-
ling area during drilling and insertion.
• Do not remove protective shields
- danger of injury!
Safety instructions
• This drilling head has been designed
for use with PRO-CENTER 2000 and
must only be attached to this machine.
This drilling head has been designed
for System 32 and for drilling dowel
holes in work pieces of wood, press-
board or plastic laminated wood.
The manufacturer is not liable for any
other applications!
• Familiarise yourself with the opera-
tion of PRO-CENTER 2000 before
working with drilling head MZK.2880.
Read the operating instructions of
PRO-CENTER 2000 first.
• Set operating mode switch (E2) to
position before changing tools, re-
setting or when working in the drilling
area.
• Only use sharp, clean drill bits when
working!
• Particular care must be taken when
working on work pieces which jut out
over the worktable.
• Secure the work piece during work!
Use the machine's hold-down clamps
to do so. If these are insufficient, find
a suitable fastening device.
• Make sure that all safety devices
function properly before starting
operation. Replace defective parts
with genuine spare ones.
• Make sure that no other tools or
objects are on the worktable aside
from your work piece before turning
on the machine!
• For your own safety, use only the
accessories recommended or stated
in the operating instructions or in
Blum's catalogue.
• Noise emissions
Emission standard at work place
4
B
Safety instructions
!
(operating cycle) = 80 dB(A).
(Measured 1.5 m above and 0.5 m
in front of worktable top according
to EN 31202 (31204 or ISO 7960.
Measuring incertainty constant K3
is 4 dB(A)).
The operator himself must decide
whether ear protection is neverthe-
less necessary on account of room
conditions, additional noise sources
and duration of operation.
• Dust emissions
If connected properly to a dust
extraction set, dust emissions fall
clearly below the technical standard
value with air velocity reaching a
minimum of 20 m/s at dust extraction
connnectors. Depression amounts to
1060 Pa.
• Do not yourself make any alterations
or modifications to the machine!
• Contact any of Blum's service points if
you have any questions or problems.

Preparing PRO-CENTER 2000
1. Mounting the large worktable
• Turn main switch to position 0
• If the small worktable supplied with
the machine has been attached,
replace it with large worktable (D1)
supplied with drilling head MZK.2880
Important
Due to possible tolerances,
the large worktable might be
slightly thicker than the small
worktable supplied with the
machine. This could have an
effect on the drilling depth
and drilling distance of the
horizontal drilling unit!
• Give the vertical drilling unit a trial
run
• Check drilling depth and adjust the
pre-positioning screws on the drilling
depth revolving handle if necessary
• Give the horizontal drilling unit a trial
run
