Keep a firm hold on the machine already before
switching it on. The mortising chain must stand
unobstructed while doing so. Apply the machine for
the mortising operation with running mortising
chain. Pay attention to a secure footing.
-
Always lead the connecting cable away from the
machine to the rear while mortising.
-
Match the feed speed during mortising to the
material thickness. Mortising too quickly leads to
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.
-
Before switching on the machine for freehand
milling, pay attention that the cross fence is
fastened and rests against the workpiece. Milling
must not start without cross fence!
-
Only use the machine outdoors or in well ventilated
rooms.
-
Wear a dust mask during machine operation.
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.
-
Wear protective gloves for all maintenance and
repair work.

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 to replace the mortising chain:
•
First slacken the mortising chain by means of
the threaded pin 14 (Fig. 1).
•
Remove the chain guard 11 (Fig. 2) by
simultaneously unfastening the two knurled
screws.
•
Unfasten the cylinder head bolt 16.
•
Unfasten and remove the countersunk bolt in
the transmission shaft.
•
Remove the chain wheel, mortising chain and
guide rail together.
•
For installation, proceed in reverse order.
•
Refit the new mortising chain together with the
chain wheel and the guide rail and pay attention
that the cutting teeth are running in working
direction (see arrow on the chain guard 11 (Fig.
2)).
•
Fasten the countersunk bolt in the transmission
shaft.
•
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!
