thickness restriction, suitable for mechani-
cal feed. Locking feature to prevent loose-
ning during startup and shutdown by positi-
ve connection of the tool with the rear
abutment flange by means of 2 driving
pins.

2. Protection against touching the tool:
Housing fully closed with the exception of
the opening for feeding the workpiece. The
door in the housing providing access to the
setting elements for adjusting the tenon
thickness is guarded by means of a safety
limit switch that is connected to the drive
motor for the milling tool and the feed dri-
ve. When the door is opened, both drives
are switched off, and the automatic brake
shuts the tool down in approx. 3 seconds.
The safety circuit of the control is designed
to meet performance level PL=c pursuant
to EN ISO 13849 (PL).

3. Safety feature of the opening for work-
piece feed-in:
The feed-in opening is adjusted to the di-
mensions of the respective workpiece by
an automatically closing protection curtain
pursuant to EN 1870-13.

4. Clamping the workpiece:
The workpiece positioned in the machine is
protected against accidental shifting by a
manual clamping device.

5. Protection against tool damage:
When the machine is set to cut angled te-
nons, a collision with the workpiece is pre-
vented by automatic correction of the start
position via retraction of the tool.

6. Setup mode:
Setup mode, selected by means of the
operating mode selection switch, is only
available when the milling tool is in stand-
still. Then, the setting of milling unit can be
changed in every direction by means of the
inching control key.

7. Chip disposal:
The chips are guided through the integra-
ted chip deflection channel either to 2 ejec-
tion chutes or 2 hose connectors.

8. Noise reduction:
The noise is reduced thanks to the almost
circular shape of the milling tool and the
closed housing. The duration of the emissi-
on is limited by automatic shutdown of the
tool at the end of the machining cycle.

9. Electrical safety:
The electrical equipment of the machine in
in accordance with the European standard
EN 60204-1. It is immune to interference
by electromagnetic fields. There is no emit-
tance of electromagnetic interference pul-
ses.

1.8 Intended use

The MAFELL tenon cutting machine ZAF
250 is exclusively intended for cutting
straight and angled tenons and to machine
flattenings in solid timber with a maximum
cross-section of 500 x 250 mm (19 11/16 x
9 27/16 in.) for straight tenons or 220 x
250 mm (8 21/32 x 9 27/32 in.) for tenons
with a tilt angle of 60°. To this end, only the
assembled milling tool comprised in the
delivery with the dimensions Ø 100 mm x
110 mm (3 15/16 Ø x 4 5/16 in.) or Ø 165
mm x 40 mm (6 1/2 Ø x 1 9/16 in.) may be
used.
The operator station of the machine is in
front of the control panel that holds the
switches for all machine functions.
Any use beyond the above is not conside-
red intended use. The manufacturer wai-
ves any and all liability for resulting dama-
ge of any kind; the risk is exclusively borne
by the user.
Likewise, the machine is not suitable for
outdoor operation in rainy weather, or in
hazardous areas.
To meet the requirements for 'intended
use', the operating company must further-
