2.7 Use according to intended purpose

The MAFELL door lock mortiser SKS 130 is exclusively intended for mortising doors made of solid wood or common derived timber products, using the mortising chains approved by us.

The machine may only be used for mortising work after it has been mounted on a door in accordance with the instructions in chapter 5.3 and 5.4.

The door lock mortiser may not be used to mortise metal doors!

The dimensions of the mortising chain sets used (guide rail, mortising chain and chain wheel) must correspond to the mortising chain sets listed in the operating instructions.

Any other use than described above is not permissible. The manufacturer cannot be held liable for any damage arising from such other use.

So as to use the machine as intended, comply with the operating, maintenance and repair instructions specified by Mafell.

2.8 Residual risks

Danger

Even if used in accordance with its intended purpose and despite conforming with the safety instructions, residual risks caused by the intended use that can lead to health consequences will always remain.

• Touching the mortising chain in the exposed area.
• Touching the part of the mortising chain that protrudes below the workpiece when mortising.
• Touching the mortising chain from the side.
• Breakage of the mortising chains and risk of the mortising chains or parts of them being hurled away.
• Touching live parts with the housing open and the mains plug not removed.
• Hearing can be impaired when working for long periods without ear protectors.
• Emission of harmful wood dusts during longer operation without extraction.

3 Safety instructions

Danger

Always observe the following safety instructions and the safety regulations applicable in the respective country of use!

Also read the safety instructions in the enclosed booklet "Safety instructions".

General instructions:

• Children and adolescents must not operate this machine. This rule does not apply to young persons receiving training and being supervised by an expert.
• Never work without the protection devices prescribed for the respective operating sequence and do not make any changes to the machine that could impair safety.
• When operating the machine outdoors, use of an earth-leakage circuit-breaker is recommended.
• Damaged cables or plugs must be immediately replaced. Replacement may only be carried out by

Mafell or an authorised MAFELL service workshop in order to avoid safety hazards.

- Avoid sharp bends in the cable. Especially when transporting and storing the machine, do not wind the cable around the machine.

Instructions on the use of personal protective equipment

- Always wear your personal protective equipment whenever you are working with the machine. Hearing protection, dust mask, protective goggles and protective gloves.

Instructions on operation:

- Provide for an unobstructed and slip-proof location with sufficient lighting.

- Do not work on workpieces which are too small or too large for the capability of the machine.

- Clamp mortising chains and guide rails appropriately and keep in order. Repair defective mortising chains professionally before reuse. Only use sharp mortising chains!

- Only remove chain guard for tool change purposes, immediately screw back on again afterwards. Never work without chain guard!

- Never transport the chain mortiser with running mortising chains! Avoid touching the ground with the running mortising chain.

- The switch may not be wedged.

- Before switching on, check whether the mortising chains are properly tensioned.

- Whenever possible secure the workpiece from pivoting or sliding away, overturning and luffing up, e.g by means of clamps.

- Only begin mortising the workpiece when the mortising chains have reached their full speed.

- Examine the workpiece for foreign objects. Never attempt to mortise into metal objects, such as nails.

- Hold on tightly to the machine, already before turning it on. The mortising chains must stand unrestricted. Apply the machine for the mortising operation with running mortising chains. Pay attention to a secure footing.

- Never reach below or laterally onto the workpiece during mortising (Risk of injury!).

- 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 chains blunting quickly.
• Only remove the machine from the workpiece if the mortising chains have 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.).
• Only start mortising the workpiece after the machine has been mounted on the workpiece in accordance with chapter 5.3 and 5.4.
• Support the clamping on the workpiece by keeping a firm hold on the machine.

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.

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 Chip extraction

Connect the machine to a suitable external dust extractor during all work generating a considerable amount of dust. The air velocity must be at least 20 m/s (65.6 ft / sec.).

The inside diameter of hose connector 7 (Fig. 2) is 35 mm (1 3/8 in.).

4.3 Mortising chain change and chain wheel change

Danger

Pull the power plug during all service work.

Pay attention that the mortising chains to be clamped have been well sharpened as this is a basic requirement for correct mortising.

Proceed as follows for exchanging the mortising chain:

• Clamp the machine vertically onto a piece of wood so that the machine cannot overturn.
• Unfasten the screw 9 (Fig. 2) and remove the chain guard 8.
• Slacken the mortising chains 4 (Fig. 1) by unfastening the two screws 3.
• Unfasten the screws 6.
• Push the guide rails 1 in direction of the chain wheels 2.
• Remove the chain wheels, mortising chains and guide rails.
• Place the new mortising chains onto the guide rails. Pay attention to the direction of travel (see direction of travel arrows on the chain guard).
• If necessary, place new chain wheels into the mortising chains.
• Refit the chain wheels, mortising chains and guide rails. In doing so, push the chain wheels onto the gear shaft in such a manner that the chain wheel groove gears into the straight pin and the circlip engages in the gear shaft groove.
• Slightly unfasten the screws 5.
• Slightly tighten the screws 6 and tension the mortising chain with the screws 3. The correct chain tension has been achieved if the mortising chain can be lifted by approx. 6 mm (1/4 in.) in the centre of the guide rails.
• Tighten the screws 5 and 6.
• Refit the chain guard 8 (Fig. 2) and secure it with screw 9.

5 Operation
