Working with circular saws, especially with the popular and widespread circular saw, are among the most dangerous and accident-prone home improvement work. Especially common are cuts on arms and hands.
For your safety:
- Read the instructions carefully and clear all open questions with an expert until you have mastered the device safely. Practice handling the unit until you can safely handle the saw.
- Splitting wedge and protective hood are important protective devices. Do not dismantle them and regularly check their functionality.
- Immediately replace cracked or deformed saw blades with intact ones.
- Use a hand brush or similar for removing chips; Do not wipe with your hand or sleeve!
- Wear tight-fitting clothing. Wide sleeves or open smocks can easily get caught in the moving parts of the machine.
- No gloves: When working on the circular saw, it is best not to wear gloves because a glove - and with it the whole hand - can be caught by the saw blade.
- Eyes: It is best to protect your eyes with goggles from flying wood or other materials.
- Nose: Wood dusts can damage your health. Always use the suction devices provided on the machines. Wear a fine dust mask or a face shield.
- Ears: Wear an earmuff! Circular saws can develop a volume of up to 105 decibels (dB) A. By comparison, a jackhammer seven meters away emits 90 dB (A).
Working safely with the circular saw:
- Machines with a motor brake are not common yet, but a plus in safety: The brake stops the saw blade shortly after switching it off.
- The rigid riving knife behind the saw blade is indispensable! It prevents the cut behind the machine from contracting again, thereby pinching the saw blade. If it is missing, the entire machine could be pushed upwards out of the cut (danger of kickback!)
- The pendulum hood (protective hood) must be movable and remain. It must cover the saw blade completely when idling and will not swing back until the machine is in contact with the material. When cutting, only the cutting zone is released.
- Switch-on lock: prevents accidental switching on.
- Pay attention to an undetectable switch: When the switch is released, the machine automatically shuts off.
Working safely on the table saw:
- Make sure that the table is firmly mounted. At most, the saw blade with motor can be adjusted diagonally.
- After switching off, the saw blade runs for a maximum of ten seconds.
- The riving knife must sit firmly and stand exactly in the direction of escape of the saw blade. It prevents workpieces from bouncing back.
- The saw blade is braked by the brake device, which acts directly on the motor shaft and only becomes active after switching off.
- The cover over the saw blade (protection against accidental contact) is present and correctly adjusted.
- Wood dust: Make sure that there is an exhaust adapter on the cover, for example, to which you can connect a household vacuum cleaner or an all-purpose vacuum using a flexible hose. Harmful wood dust can not be released during sawing.
- Use a push stick to guide the workpiece to the saw blade when the distance between the rip fence and the saw blade is less than 120 millimeters.
- Make sure that the part of the saw blade that is below the table is protected against contact by a cover.
