In such cases, do not carry out any work on the machine; secure the machine by pulling the mains plug. To protect long hair, you must wear a cap or hairnet. Wear tight-fitting clothing. Take off jewelry, rings and watches. Wear safety shoes; never wear walking shoes or sandals. Use personal protective equipment prescribed for use in accordance with the instructions. When working on the machine, do not wear gloves. For safe handling of the saw blade, suitable protective gloves must be worn. When working with long workpieces, use a suitable desktop extension, roller bearings, etc. Observe the safety sections in this instruction manual. Consider the travel time of the machine during braking, it should not exceed 10 seconds in any case. When cutting round billets, it is necessary to protect them from turning. When cutting workpieces inconvenient for processing, use suitable aids for fastening. Lower the saw blade guide as close as possible to the workpiece. With the table tilted, set the longitudinal stop on the lower half of the table. 2

3 Care must be taken to ensure that all workpieces are securely held and moved safely during processing. Only remove cut and jammed workpieces when the motor is off and when the saw blade stops completely. The machine should be installed so that there is enough space for its maintenance and the direction of the workpieces. Watch for good lighting. Make sure that the machine stands steadily on a solid and level foundation. Make sure that the electrical wiring does not interfere with the workflow and that it cannot be tripped over. Keep your work area clear of interfering workpieces and other items. Be attentive and concentrated. Take work seriously. Never operate the machine under the influence of psychotropic drugs such as AL-KOL and drugs. Bear in mind that medications can also have harmful effects on your behavior. Remove strangers, especially children, from the danger zone. Do not leave a running machine unattended. Turn off the machine before leaving the workplace.

4 Although there is a connection between the level of emission and the harmful effects, it cannot be reliably concluded from this whether additional measures are needed. Factors that influence the actual level of harmful effects at the workplace cover the duration of exposure, room characteristics, other noise sources, etc., for example, the number of machines and other neighboring processing processes. In addition, the permissible level of harmful effects differs in different countries. Despite this, this information is useful in order to enable the user of the machine to better assess the exposure to hazards and possible risks. Dust extraction The JWBS-14 type band saw was evaluated in terms of the harmful effects of dust at an air speed of 20 m / s on a suction nozzle with a diameter of 100 mm: Discharge 1250 Pa Volumetric flow 565 m³ / h The currently valid maximum allowable dust concentration of 2 mg / m³ is reliably observed at the workplace. 5.
