Use of the machine as log saw for firewood with standard saw blade. Noise power level (Load)

= 115 dB(A) The factor of measurement uncertainty is 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.12 Operating times Before initiating the device please observe the provisions pertaining to corresponding laws (regional provisions) for the noise control.

Carefully read opera-tor’s manual and the safety instructions be-fore starting the machine and observe the instructions when operating. Wear protective gloves. Wear safety shoes. Wear eye protection. Wear ear protection. Wear protective clothing. Use light-duty breathing protection. Risk of injuries of fingers and hands by the saw blade. Shut off engine and remove power cord before performing cleaning, maintenance or repair work. Warning of hot surfaces. Danger of burning! Do not touch hot engine parts. Direction of saw blade rotation This product complies with European regulations specifically applicable to it. Electrical devices do not go into the domestic rubbish. Give devices, accessories and packaging to an eco-friendly recycling. According to the European Directive 2012/19/EU on electrical and electronic scrap, electrical devices that are no longer serviceable must be separately collected and brought to a facility for an environmentally compatible recycling.

Normal intended use This machine is designed for cross cutting firewood in the house and hobby field. Cutting of round material having a diameter smaller than 30 mm and greater than 240 mm is not allowed as these pieces can not be held safely. The length of the material to be cut must not exceed 1000 mm. The length of the material must be 200 mm as a minimum. Only high-quality saw blades acc. to EN 847-1 up to a max. diameter of 700 mm must be used. Because it has no extraction device this machine must only be used outdoors. Only work pieces are allowed to be processed which can be safely placed and held in the jigging device. 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. The intended usage also includes compliance with the operating, servicing and repair conditions prescribed by the manufacturer and following the safety instructions included 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 is deemed not to be intended use. The manufacturer is not liable for any type of damage resulting from this: the user bears the sole risk. 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. The machine may not be used in a potentially explosive environment or be exposed to rain. 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, e.g. when replacing the saw blade. Injury by catapulted workpiece parts. Throwback of the workpiece or workpiece parts. Breaking or catapulting of saw blade. 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. Emission of harmful wood dusts. Wear therefore a protective mask. Noise emission: Use saw blades designed for noise reduction and keep the machine in a good condition. In addition, in spite of all the precautionary measures taken, non-obvious residual risks can still exist.13 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.

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. This unit may not be used by persons having reduced physical, sensory or cognitive abilities or by persons with lack of adequate knowledge or experience unless they are supervised or instructed by a person who is responsible for them. The machine must not be operated by children. Persons under the age of 18 must not operate the circular saw. Persons who have not read this operating instruction manual may not operate this unit. Children must be supervised to make sure that they do not play with the device. Keep children away from machine. Never leave the saw unattended. Keep other persons away. Do not allow other persons, especially children, to touch the tool or the cable. Keep them away from your working area. 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 suitable personal protective equipment: − ear protection (Sound intensity level at workplace can exceed 85 dB (A)) − eye protection − breathing protection − gloves when working on saw blades saw blade change, for example (whenever possible transport saw blade in a tool holder). Dust exposition depends on the type of material to be sawed. Because this firewood saw has no extraction system, it may only be operated outdoors. Dust arising during work is often harmful to health and should not come into the human body. Wear a suited protective mask. Thoroughly remove accumulated dust, e.g. by vacuum. ONLY OPERATE the circular saw on a − solid − level − slip-free − vibration free surface 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. Avoid abnormal posture. Provide a safe standing position and keep at any time the balance. Do not lean forward. Assume the correct work posture. Stand in front of the operating side frontally to the saw blade line. 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. Immediately report any malfunction on the machine including isolating safety devices or saw blade after you have detected them. Only operate the saw with complete and correctly attached safety equipment and do not alter anything on the machine that could impair the safety. Replace the plastics inserts 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. To minimise the noise emission make sure that you work with a sharp saw blade and that all elements for noise reduction (covers, etc.) are properly attached or adjusted. 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 "Technical Data" and is suitable for the work piece material. Observe the maximal speed indicated on the saw blade. Always use genuine saw blade flanges. Arrange the stack of work pieces to be cut and the finished work pieces close to the work place. 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. The length of the material to be cut must not exceed 1000 mm. The length of the material must be 200 mm as a minimum. Only wood pieces up to a max. diameter of 240 mm are allowed to be cut to avoid dangerous turnover cutting. 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. Do not remove cut or other parts of the work piece from the cutting area with the machine still running unless you use a pushstick. 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)14 − 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. Adopt safe procedures for cleaning, maintenance and regular removal of chips and dust to prevent the risk of fire. Make sure during its entire foreseeable life cycle that the machine including its parts cannot tip over or move in an uncontrolled manner when transporting, assembling, putting out of service and scrapping

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 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.
