ISO 7960:1995 Appendix A, A.2 b) Application of the machine as construction circular saw with standard saw blade. Guaranteed sound power level L

= 114 dB (A) Sound pressure level at the workplace No-load L

= 92.8 dB (A) Load L

= 98.5 dB (A) The factor of measurement uncertainty is K = 4 dB. 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.

Operating times Before initiating the device please observe the provisions pertaining to corresponding laws (regional provisions) for the noise control.

User information. This information helps you to use all the functions optimally.13 Assembly, operation and servicing. Here you are explained exactly what to do.

Normal intended use This construction circular saw is exclusively designed for lengthwise and cross cutting of solid wood and plate material such as chipboard, wood core plywood and MDF plates with square or rectangular cross section in the open outside of enclosed areas using carbide tipped circular saw blades acc. to EN 847-1. The thickness of the wood material must not exceed: CPHL 400: 126 mm CPHL 450: 150 mm CPHL 500: 175 mm The diameter of the saw blade must be within the values below: CPHL 400: 395 – 400 mm CPHL 450: 445 – 450 mm CPHL 500: 495 – 500 mm Cross cuts may only be performed in conjunction with a mounted cross- cutting fence. Only materials that can be safely placed are allowed to be cut. The use of saw blades made of HSS steel (high-alloy high speed steel) is not permitted since this steel is hard and brittle. Risk of injury through saw blade breakage and expulsion of saw blade pieces. Normal intended use also includes the observance of the manufacturer's operating, maintenance and repair conditions, as well as strict adherence to the safety inspections listed in the instructions. The relevant accident prevention regulations for the operation as well as the other generally acknowledged occupational medicine and safety rules must be complied with. Any other use does not conform with the normal intended use of the circular saw bench. The manufacturer is not liable for any resulting damage; the user bears all risks! Unauthorized modifications to the saw preclude any liability of the manufacturer for resulting damages of any kind. The saw may only be equipped, used and serviced by persons who are familiar with it and have been instructed on the hazards. Repair works may only be carried out by us or by a customer service agent nominated by us. This machine must not be used in potential explosive atmospheres. Metallic parts (wires etc.) have unconditionally to be removed from the material to be cut.

Risidual risks Even if used properly, residual risks can exist even if the relevant safety regulations are complied with due to the design determined by the intended purpose. Residual risks can be minimised if the “Safety instructions” and the “Normal intended use” as well as the whole of the operating instructions are observed. Observing these instructions, and taking proper care, will reduce the risk of personal injury or damage to the equipment. Danger of injury of fingers and hands by the tool (saw blade) or work piece. Therefore, wear gloves (e.g. when replacing the saw blade). Risk of injury when removing chips while the saw blade still rotates. Only remove chips after the saw blade and the saw unit (motor) has come to a standstill. Injury by catapulted workpiece parts. Throwback of the workpiece or workpiece parts. Breaking or catapulting of saw blade. Only operate the saw with complete and correctly attached safety equipment and do not alter anything on the machine that could impair the safety. Emission of harmful wood dusts. Therefore, wear a dust mask. Risk from electricity, by using non-standard electrical connections. Touching live parts of opened electrical components. Impairment of hearing when working on the machine for longer periods of time without ear protection. In addition, in spite of all the precautionary measures taken, non-obvious residual risks can still exist.

Safe working Woodworking machines can be dangerous if not used properly. If electrical tools are used, the fundamental safety precautions must be met to preclude the risks of fire, electric shock and injuries to persons. Before starting this device, read and keep to the following advice. Also observe the preventive regulations of your professional association and the safety provisions applicable in the respective country, in order to protect yourself and others from possible injury.

Pass the safety instructions on to all persons who work with the machine.

Keep these safety instructions in a safe place. Make yourself familiar with the equipment before using it, by reading and understanding the operating instructions. Be attentive. Be careful what you do. Behave sensibly when working. Do not use the device when you are tired or under the influence of drugs, alcohol or medicaments. One moment of care- lessness when using the device can result in serious injuries. Avoid abnormal posture. Provide a safe standing position and keep at any time the balance. Do not lean forward. Wear suitable work clothes: − do not wear loose-fitting clothes or jewellery; they can catch in moving parts. − slip-proof shoes − hairnet in case of long hair Wear personal protective equipment: − ear protection (Sound intensity level at workplace can exceed 85 dB (A)) − safety goggles − gloves when you replacing the saw blade ONLY OPERATE the circular saw on a − solid − level − slip-free − vibration free surface When the saw is connected to a chip exhaustor: − Required air flow rate: 1150 m³/h, negative pressure on the suction nozzle 1160 Pa at an air velocity of 20 m/s. − Start the chip exhaustor before starting the machining. Keep your workplace in an orderly condition! Untidiness can result in accidents. Take into consideration environmental influences: − Do not expose the saw to rain. − Do not use the saw in moist or wet ambience. − Provide for good illumination. − Do not use this saw near inflammable liquids or gases. Never leave the saw unattended. Adhere to national regulations that might specify an age limit for the user of the unit. Keep other persons away. The operator is responsible for other people within the working area. Do not allow other persons, especially children, to touch the tool or the cable. Keep them away from your working area. Always stand to the side of the danger zone (saw blade) when working at the bench. Start cutting only when the saw blade has reached its required speed. Do not overload the machine! You work better and safer in the given performance range.

The circular saw must only be operated with all the correctly mounted guards.14 The supplied splitting wedge must be used. Fig. 15 shows how the splitting wedge is inserted and reset. Replace the bench insert if the sawing gap is worn. Do not use any cracked saw blades or such that have changed their shape. Use only well sharpened saw blades as edgeless saw blades increase not only the risk of backstrokes but also charge the motor. Do not use saw blades made of high speed steel (HSS) since this steel is hard and brittle; use only tools according to EN 847-1. The use of other tools and other accessories can signify a risk of injury for you. Pay attention that the saw blade conforms to the dimensions specified under "Selection of saw blades" and is suitable for the work piece material. 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. Ensure that cut off pieces are not caught up by the saw blade and projected away Do not use the saw for unsuitable purposes (see “Normal intended use”). Remove all nails and metallic objects from the work piece before sawing. Pay attention that the work piece does not contain any cables, ropes, cords or the like. Only cut work pieces with dimensions that allow secure holding while sawing. It is only allowed to cut wood the thickness of which does not exceed: CPHL 400: 126 mm CPHL 450: 150 mm CPHL 500: 175 mm When cross cutting round wood it is required to secure the work piece against turning using a pattern or holding device. Use a saw blade that is suited for cross cutting. Use a pushing stick when rip sawing narrow workpieces (space between saw blade and rip fence less than 120 mm). Always keep sufficient distance to the saw blade. Maintain sufficient distance from driven components during operation. The saw blade runs after. Wait until the saw blade has come to a standstill before remove splinters, chips and waste. Do not slow the saw blade down by applying lateral pressure to it. Do not remove splinters, shavings and waste with your hands from the dangerous area of the saw blade. Remove cutting waste from the machine (as required) to prevent any safety impairment at the workplace. This also applies to sawdust. Keep the chip clearance free. Switch the machine off and remove the mains plug from the socket when − carrying out repair works − maintenance and cleaning − removal of faults (this also includes the removal of jammed splinters) − checks of connecting lines, whether these are knotted or damaged − transporting the saw − changing the saw blade − leaving the saw (also for short-term interruption) Maintain your saw with care: − Keep your tools sharp and clean in order to be able to work better and safer. − Follow the maintenance instructions and the instructions for tool exchange. − Keep handles dry and free of oil and grease. Check the machine for possible damage: − Before further use of the machine the protection devices or slightly damaged parts must be checked carefully for their proper and intended function. − Check whether the movable parts function perfectly and do not stick or whether the parts are damaged. All parts must be correctly installed and fulfil all conditions to ensure perfect operation of the saw. − Damaged guards and parts must be properly repaired or exchanged by a recognized, specialist workshop; insofar as nothing else is stated in the instructions for use. − Damaged or illegible safety labels should be replaced immediately. Do not allow any tool key to be plugged in! Before switching on, check always that wrenches and adjusting tools are removed. Store unused equipment in a dry, locked place out of the reach of children. Electrical safety Design of the connection cable according to IEC 60 245 (H 07 RN-F) with a core cross-section of at least − 1.5 mm² for cable lengths up to 25 m − 2.5 mm² for cable lengths over 25m − 2,5 mm² for CPHL 500 Long and thin connection lines result in a potential drop. The motor does not reach any longer its maximal power; the function of the device is reduced. Plugs and coupler outlets on connection cables must be made of rubber, plasticised PVC or other thermoplastic material of same mechanical stability or be covered with this material. Protect yourself against an electric shock. Avoid touching earthed parts with your body. The connector of the connection cable must be splash-proof. Wind off completely the cable when using a cable drum. Do not use the cable for purposes for which it is not meant. Protect the cable against heat, oil and sharp edges. Do not use the cable to pull the plug from the socket. Regularly check the saw cable and if damaged, have it renewed by a recognised skilled electrician. When running the connection line observe that it does not interfere, is not squeezed, bended and the plug connection does not get wet. Regularly check the extension cables and replace them if they are damaged. Do not use any defective connection cables. When working outdoors, only use extension cables especially approved and appropriately labelled for outdoor use. Do not set up any provisional electrical connections. Never bypass protective devices or deactivate them. Only hook up the machine by means of a fault-current circuit breaker (30 mA). The electrical connection or repairs to electrical parts of the machine must be carried out by a certified electrician or one of our customer service points. Local regulations – especially regarding protective measures – must be observed. Repairs to other parts of the machine must be carried out by the manufacturer or one of his customer service points. Use only original spare parts. Accidents can arise for the user through the use of other spare parts. The manufacturer is not liable for any damage or injury resulting from such action.

Before the first start-up

To achieve flawless functioning of the machine, please follow the instructions listed: Place the saw at a location which meets following conditions: − outdoor − secured against slipping − free of vibrations − even − free of tripping hazards − adequate light15

• Check the following prior to use: Defective connecting lines (cracks, cuts, etc.). Never use defective lines! Proper working condition of the safety guard. Correct splitting wedge setting (see also Fig. 15). Perfect condition of the saw blade. The push stick must be within easy reach.
• Never use saw blades that are cracked or have become deformed.
• Do not use saw blades made of high-speed steel.
• Always stand to the side of the danger zone (saw blade) when working at the bench.

Start-up Checking the safety devices (before each starting): - Lift and lower the safety guard to check that it can be moved freely. In its rest position it must fully cover the saw blade and rest on the saw table. (See also “Possible faults”.) - Check the switch by turning it on and off. Do not use any device where the switch can not be switched on and off. Damaged switches must be repaired or replaced immediately by the customer service. - Brake The saw blade must stand still within 10 seconds after it was switched off. The brake is defective if this time is exceeded. The saw must then be repaired by the manufacturer or a workshop appointed by the manufacturer. - Pushstick ⇒ Replace defective pushsticks by new ones. Rotating direction of the saw blade

Ensure that the rotational direction of the saw blade is the same as the rotational direction given on the guard (15)

The rotating direction of three-phase motors can be changed by inserting a screwdriver in the connector collar provided for this purpose and turn left or right while exerting a light pressure to adjust the correct rotating direction.

Selection of saw blades ⇒ Observe the splitting wedge thickness "S"; it is etched into the side of the splitting wedge. The splitting wedge must not be thinner than the saw blade, and not thicker than the kerf width produced by the blade. The rating plate specifies maximum and minimum saw blade diameters, as well as the hole diameter. Do not use saw blades that are designed for a lower max. speed (see identification on the saw blade) than the motor speed (see the technical data). L Mains connection Compare the voltage specified on the rating plate (on the side of the table board), e.g. 230 V, with the mains voltage. Connect the circular saw bench to a correctly earthed socket outlet. • Alternating-current motor: Schuko (earthed) socket, mains voltage 230 V, with earth-leakage circuit breaker (FI switch 30 mA). • Three-phase motor: CEE socket, 3-pin + N + PE, mains voltage 380 V or 400 V, with earth-leakage circuit breaker (FI switch 30 mA). Use connecting and extension cables in conformity with IEC 60245 (H 07 RN-F) with a conductor cross-section of at least:

• -1.5 mm² for a cable length of up to 25 m.

• -2.5 mm² for a cable length exceeding 25 m.

• 2,5 mm² for CPHL 500 L Main fuse: 400 450 500 CPHL 16 A inert 16 A inert 20 A Power system impedance In case of disadvantageous power system conditions short-term voltage reductions can occur during the event of switching on of the device which can influence other devices (e.g. jittering of a lamp).
