Characteristic data of noise

DIN EN ISO 4871

Use of the machine as a bench to circular saw with standard circular saw blade.

	Noise power level	Sound pressure level at the workplace
Load	L_WA = 108,7 dB(A)	L_pA = 95,7 dB(A)
Factor of measurement uncertainty	K_WA = 3 dB(A)	K_pA = 3 dB(A)

The values given are emission values and must therefore not simultaneously represent safe workplace values too. Although there is a relationship between emission and immersion levels, it can be reliably deduced whether additional precautionary measures are necessary or not. Factors, which can influence the immersion level currently existing at the workplace include the duration of the effects, the special type of the workroom, other noise sources, etc. e.g. the number of machines and other adjacent processes. The permissible workplace values can also vary from country to country. This information should however enable an improved assessment of the danger and risk to be carried out.

- When sawing wood, circular saws must be connected to a dust collection device.

■ Always make sure that no excessive dust concentration can occur.

- Always keep the saw blade well sharpened and make sure that the safety guard is lowered over the workpiece.

— Always use a suited extraction system.

— Wood dust is explosive and can be harmful.
- In particular tropical woods as well as beech and oak are classified as carcinogenic.

■ Never leave the saw unattended.

• Persons under the age of 18 must not operate the circular saw. An exception is youngsters under the age of 16 within the scope of their vocational training under supervision.
• Keep other persons away.

Do not allow other persons, especially children, to touch the tool or cable.

Keep them away from your working area.

■ Take up a working position, in which you are always to the side of the saw blade outside of the cutting level.
- Remove all nails and metal objects from the work piece prior to sawing.
- Pay attention that the work piece does not contain any cables, ropes, cords or the like.
- Only begin cutting after the saw blade has reached its required rotational speed.
- Do not overload the machine! You work better and safer in the given performance range.

• Make sure to select a saw blade that is suited for the material to be cut.
• Use the riving knife provided. It must be set so that its distance to the tooth rim of the saw blade is no more than 2-5 mm above the bench.
• When mounting the saw blade check that the riving knife is aligned with the saw blade.
• Use an additional support (e.g. table, stand) for longer workpieces to prevent the machine from tipping over. Do not allow other persons to hold the workpiece.

■ Make sure to safely hold and guide all workpieces when they are machined. Do not cut too small workpieces.
- Use only fine-tooth saw blades to cut thin or thin-wall work pieces.
- Only saw one work piece at a time. Never saw several work pieces at the same time or do not bundle several individual pieces together for cutting. There is danger that individual pieces may be caught by the saw blade in an uncontrolled manner.
- Do not use the saw for purposes it is not intended for (see intended use).
- When longitudinally cutting narrow workpieces (distance between the saw blade and the parallel rip fence less than 120 mm), use the pushstick.
- To push narrow workpieces against the parallel rip fence, use a pushstick.

→ Pushsticks can be purchased in retail outlets.

■ Do not use defective pushsticks.
- Always keep the pushstick or the handle for a pushing block on the circular table saw when they are not used.
- You work better and safer in the given performance range. It has to be positioned in the way that the saw blade is covered completely except for the part necessary for the work piece machining.
- Ensure that cut off pieces are not caught up by the saw blade and projected away.
- Do not remove splinters, chips and waste from the hazardous area of the saw blade by hand.
■ Always use the mitre guide for cross cutting.
- It is not permissible to use wobble devices and groove milling tools.
- Circular saws may not be used for slitting (groove ending in the workpiece).
- Never reach in the running machine. Keep hands, fingers and arms away from a rotating saw blade.
- Never reach over or around the saw blade. Do not reach behind the guide bar close to the saw blade; the distance between hand and rotating saw blade is too small.
