motor overload, to unclean mortises and to the
mortising chain blunting quickly.
- Only remove the machine from the workpiece if it
has come to a standstill.
- Do not reach into the chip ejector and the
unprotected area of the mortising chain while the
machine is running.
- The wood dust arising during mortising impairs the
necessary view and is partly injurious to health. If
the machine is used for longer periods, it must
therefore be connected to a chip extractor, e.g. a
portable small extractor, if the work is not carried
out outdoors or in a sufficiently ventilated room.
The air velocity must be at least 20 m/s (65.6
ft/sec.).
Instructions on service and maintenance:
- Regularly cleaning the machine, especially the
adjusting devices and guides, constitutes an
important safety factor.
- Only original MAFELL spare parts and accessories
may be used. Otherwise the manufacturer will not
accept any warranty claims and cannot be held
liable.

Setting / Adjustment

4.1 Mains connection

Prior to commissioning make sure that the mains
voltage complies with the operating voltage stated on
the machine's rating plate.

4.2 Installation mortising chain set

Danger
Pull the power plug during all
service work.

Lightly screw on the guide rail with the cylinder
head bolt. Pay attention that the guide rail rests
planely in the guide on the gearbox case and
possibly unscrew the threaded pin 14 (Fig. 1).

The installation of mortising chain and chain
wheel is carried out as described under 4.3 and
4.4.

4.3 Mortising chain change

Danger!
Pull the power plug during all
service work.
Pay attention that the mortising chain to be clamped
has been well sharpened as this is the basic
requirement for correct mortising.
Proceed as follows for exchanging the mortising
chain:

First slacken the mortising chain by means of
the threaded pin 14 (Fig. 1).

Remove the chain guard 11 (Fig. 2) and
unscrew the cylinder head bolt 16. During a
chain wheel change, the countersunk screw in
the gear shaft must be unscrewed with the Allen
key fastened on the machine by knocking lightly
against the key.

For installation, proceed in reverse order.

Slide the guide rail 12 (Fig. 1 and Fig. 2) in the
direction of the chain wheel and detach the
chain wheel together with the mortising chain.

Refit the new mortising chain together with the
chain wheel and pay attention that the cutting
teeth are running in working direction (see arrow
on the chain guard 11 (Fig. 2)).

Lightly tighten the cylinder head bolt 16 and
clamp the mortising chain with the threaded pin
14 (Fig. 1). The correct chain tension has been
achieved if the mortising chain can be lifted
approx. 6 mm (1/4 in.) in the middle of the guide
rail.

Securely retighten the cylinder head bolt 16
(Fig. 2) after completion of the adjustment work.

Refit the chain guard 11!

4.4 Chain wheel change

Danger
Pull the power plug during all
service work.
