Noise parameters

The noise emission values determined according to EN 23746 for the sound level and according to EN 31202 (coefficient of correction k3 calculated according to Appendix A.2 of EN 31204) for the sound level at the workplace are as follows, based on the working conditions listed in ISO 7904 Appendix A:

Sound level in dB

Idle running L_WA = 90 dB(A)

Operation L_WA = 105 dB(A)

Sound level at the workplace in dB

Idle running L_pAeq = 77,2 dB(A)

Operation L_pAeq = 89,3 dB(A)

A measurement uncertainty allowance K = 4 dB

applies to the mentioned emission values.

Dust emission values

The dust emission values measured according to the “Principles for the inspection of the dust emission (concentration parameters) of wood working devices” of the Technical Committee Wood are below 2 mg/m ^3 . Thus, a permanently reliable compliance with the TRK limit value for wood dust valid in the Federal Republic of Germany can be expected if the machine is connected to a proper operational aspiration with an air speed of at least 20 m/s.

This avoids overloading the circuit fuse. After turning off the machine tool, the vacuum exhaust unit remains on for an additional 3-4 seconds and is then automatically switched off. Remaining dust is thereby removed by vacuum exhaust, as required by German regulations governing hazardous materials. This results in savings in electricity consumption and reduces noise levels, as the vacuum exhaust unit is on only during machine tool operation.
• For work in commercial spaces, the scheppach dust remover woova 7 must be used. Do not remove or shut

off vacuum exhaust systems or dust removers while machine tools are operating.

• Any other use exceeds authorization. The manut is not responsible for any damages resulting from unauthorized use; risk is the sole responsibility of the operator.
• The safety, work and maintenance instructions manufacturer as well as the technical data given in the calibrations and dimensions must be adhered to.
• Relevant accident prevention regulations and other, generally recognized safety-technical rules must also be adhered to.
• The scheppach Table Circular Saw may only be used, maintained, and operated by persons familiar with and instructed in its operation and procedures. Arbitrary alterations to the machine release the manu facturer from all responsibility for any resulting damages.
• The scheppach Table Circular Saw may only be used with original accessories and saw blades from the manufacturer.

⚠️ Remaining hazards

The machine has been built using modem technology in accordance with recognized safety rules. Some remaining hazards, however, may still exist.

• The rotating saw blade can cause injuries to fingers and hands if the work piece is incorrectly fed.
• Thrown work pieces can lead to injury if the work piece is not properly secured or fed, such as working without a limit stop.
• Noise can be a health hazard. The permitted noise level is exceeded when working. Be sure to wear personal protective gear such as ear protection.
• Defective saw blades can cause injuries. Respect the structural integrity of saw blades.
• The use of incorrect or damaged mains cables can lead to injuries caused by electricity.
• The operating instructions supplied with the special accessories must be observed and carefully read when scheppach special accessories are used.
• Even when all safety measures are taken, some remaining hazards which are not yet evident may still be present.
• Remaining hazards can be minimized by for instructions in „Safety Precautions“, „Proper Use“ and in the entire operating manual.

Adjustment of the clipping wedge, Fig. 12

The adjustment of the clipping wedge must be performed after each saw blade exchange.

The clipping wedge must be in alignment with the saw blade. The distance between saw blade and clipping wedge must not exceed 8 mm.

The clipping wedge is an important protection device that guides the work piece and avoids that the cutting joint behind the saw blade is closed. Thus, the blowback of the work piece is safely avoided.

Pay attention to the clipping wedge thickness (see imprinted figures on the clipping wedge). The clipping wedge must not be thinner than the saw blade base body and not thicker than the cutting joint width.

Putting into operation

Please observe the safety instructions.

The machine may only be operated with completely installed protection and safety devices.

After the connection to the mains supply the machine is operational.

The covering cap must be lowered onto the work piece during each work cycle.

To perform hidden cuts, release the wing cut, and then remove the support sheet with the covering cap.

Notes on working

Working on circular saw benches

Cutting narrow work pieces, Fig. D

(Width of work piece less than 120 mm)

Tool: circular saw blade for length cuts

Work step:

Adjust the parallel stops to the width of the intended work piece. Feed work piece with both hands. In the area of the saw blade use the push stick and push the work piece beyond the splitting wedge. When working with shorter work pieces use the push stick from the very beginning.

Cutting strips and corners, Fig. C

Tool: Circular saw blade for line cuts

Work step:

Install parallel stops with a flatter guide side or use lower auxiliary stops. Feed the work piece with a push board until the end of the work piece is in the area of the splitting wedge. Prevent longer work pieces from tipping over at the end of the cutting process by using the bench extension.

Note: Attachments which require a connection to parts of the machine must be bolted down. Screw clamps can only provide secondary connections to machines.

Cross-cutting narrow work pieces, Fig. D

Tool: Fine toothed cross cut blade

Work step:

Adjust diversion strip so that sawed off pieces cannot come into contact with the protruding part of the saw blade. Feed the work piece only with the cross stop or with the cross slide. Do not use hands to remove excess wood from the area of the work piece.

Blind cutting, mortise and tenon, Fig. E + F

Work step:

Adjust the splitting wedge to be the rear machine cover (Setting for blind cut). Adjust the parallel stop to the mortise or tenon dimension and secure against sideward movements.

Feed work piece with feeding batten. Right hand secures the work piece against falling over. Do not place hand on the forward edge of the work piece.

After cutting, return the feeding batten with the work piece. The measurements of the work piece receiver rebate of the feeding batten must correspond to the work piece measurements. In order to apply sufficient pressure to the work piece, the notching depth must be approx 1 mm less than the thickness of the work piece. If the mortise depth or the tenon height attains the measure of the stop height C, than a detachable board B secured with screws A can be used for raising the stop.

Blind cutting, rebates, Fig. G

Tool: circular saw blade for line cuts

Work step:

When rebating on the stop, select the order of cuts so that the cut strip comes out on the side of the saw blade not lacing the stop.

In order to perform blind cuts and rebates, remove the upper machine cover or flap open the safety cap and lower the splitting wedge. Carefully feed the work piece (W necessary, secure rear stop against swinging motions).

Cutting of wedges, Fig. H

Tool: circular saw blade for line cuts

Work step:

Keep the saw slot in the table as narrow as possible. Feed the work piece with the wedge cutting batten past the splitting wedge. Remove wedge at that point. Only use wedge cutting battens that feed the wedge safely along the table (weather boards or cover strips that go along the entire length of the wedge cutting batten).

Insert cutting of shorter work pieces, Fig. K

Work step:

Remove the splitting wedge and the upper machine cover, or flap open the safety cap. Lighten the splitting wedge mounting. Adjust cross stop to the setting measurements and secure with two clamps (use wooden blocks on table). Put work piece against cross stop and evenly lodge. Feed work piece up to the cleft or to the second cross stop. Remove work piece.

Insert cutting of larger work pieces, Fig. L

Work step:

Remove splitting wedge and upper machine cover. Attach set cutting attachment to parallel stop. Adjust back kick block with the work piece receiver and the check block. Put work piece against the back kick block, evenly lodge and feed up to the check block and retract in a safe position. After insert cutting: Promptly reinstall the wedge and the upper cover.

Servicing

Pay attention to the safety instructions on page GB8.

Turn off the motor and pull the plug before servicing or cleaning the machine.

All protection and safety devices must be immediately assembled again following repairs and servicing.

1. The assemblage of the circular saw is largely service-free, including the electric motor. Exceptions to this are the normal wear and tear of the saw blades as well as the bench insert. If needed, exchange the used bench insert.
2. The bench surface should always be kept resin-free.
3. Keep the saw blade protection box free of wood and chip residue. When the power plug is pulled, open the protection box cover and remove any saw dust obstructions.
4. The motor brake is maintenance-free and will function for at least 5000 switch operations. If the after-running time exceeds ten seconds, please inform the manufacturer.
