-

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.

4 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!
