Sound levels at the workplace LpA = 83.7 dB(A) LpA = 90.6 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 immission levels, it can be reliably deduced whether additional precautionary measures are necessary or not. Factors, which can influence the immission 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.

Carefully read operator’s manual before handling the machine.

Symbols Operating instructions Threatened hazard or hazardous situation. Not observing this instruction can lead to injuries or cause damage to property.

L Important information on proper handling of the saw. Not observing this instruction can lead to faults in the machine.

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

ƒ Impairment of hearing when working on the machine for longer periods of time without ear protection. ƒ Emission of harmful timber dust when operating without exhaust suction. In addition, in spite of all the precautionary measures taken, non-obvious residual risks can still exist.

Normal intended use ƒ The circular saw is solely intended use for the longitudinal and transverse cutting of solid timber, panel materials such as chipboard, wood core plywood, and medium density fibreboard (MDF) using HM circular saw blades, whereby only saw blades that comply with the standard EN 847 – 1 may be used. ƒ The use of saw blades made of HSS steel (high-alloy high speed tool steel) is not permissible, because this steel is hard and brittle. Risk of injury due to the saw blade breaking and pieces of saw blade spinning off. ƒ Round materials (logs, pipes, etc.) are not permitted to be cut without a special device for this purpose. ƒ The diameter of the saw blade must lie between 245 and 254 mm. ƒ Only workpieces which have been securely mounted and aligned can be processed. ƒ 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. ƒ The relevant accident prevention regulations for the operation as well as the other generally acknowledged occupational medicine and safety rules must be complied with. ƒ Any other use is deemed not to be use as prescribed. The manufacturer is not liable for any type of damage resulting from this: the user bears the sole risk. ƒ Independently made alterations to the circular saw preclude any liability of the manufacturer for resulting damages of any kind. ƒ The circular saw may only be equipped, used and serviced by persons who are familiar with these and have been instructed in the hazards. Repair works may only be carried out by us or by a customer service agent nominated by us. ƒ The machine may not be used in a potentially explosive environment or be exposed to the rain. ƒ Metal parts (nails, etc.) must be removed from the timber to be sawn.

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 commissioning this product, 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.

L L Pass the safety instructions on to all persons who work with the machine. Keep these safety instructions in a safe place.

ƒ Avoid unusual posture. Ensure that you have stand in a secure standing position and maintain your balance at all times. ƒ Be attentive. Be careful what you do. Behave sensibly when working. Do not use the saw if you are tired. ƒ Wear suitable work clothes: − do not wear loose-fitting clothes or jewellery; they can catch in moving parts. − slip-proof shoes − wear a hair-net if your hair is long ƒ Wear protective clothing: − ear protection (sound pressure levels at the workplace usually exceed 85 dB(A) − safety goggles − breathing mask when carrying out works that produce a lot of dust ƒ Only operate the circular saw on a − firm − level − slip-free − vibration free surface ƒ Keep your workplace in an orderly condition! Untidiness can result in accidents. ƒ Take into consideration environmental influences: − Do not expose the saw to rain. − Do not use the saw in a damp or wet environment. − Ensure that the workplace is well lit. − Do not use the saw near to flammable liquids or gases. − The timber dust created while operating the machine impairs the visibility required and is partially damaging to health. If the machine is not used in the open air, a shavings exhausts must be attached to both exhaust outlets (e.g. small transportable dust remover). ƒ Never leave the saw unattended.

Residual 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 information” and the “Intended usage” as well as the whole of the operating instructions are observed. Potential risks: ƒ Risk of injury to fingers and hands caused by the tool (saw blade) or workpiece (e.g. when changing the saw blade). ƒ Injury from parts of the workpiece spinning off. ƒ Throwback of the workpiece or workpiece parts. ƒ Breakage and spinning off from the saw blade. ƒ Risk from electricity, by using non-standard electrical connections. ƒ Touching live parts of opened electrical components. 19

ƒ Switch the machine off and remove the mains plug from the socket when − carrying out repair works − carrying out servicing and repair works, removal of faults (this also includes removing clamped splinters) − Transporting the saw − Changing the saw blade − leaving the saw unattended (even during short interruptions) ƒ Look after your saw with care: − Keep the tools sharp and clean to be able to work better and more safely. − Follow the servicing instructions and the information about changing tools. − Keep handles dry and free of oils and grease. ƒ Check the machine for possible damage: − Before continuing to use the machine, the protective devices must be inspected to ensure that they work perfectly and with their 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. ƒ Do not allow any tool key to be plugged in! ƒ Store the unused machine in a dry locked place away from the reach of children.

ƒ 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. ƒ Keep other persons away. Do not allow other persons, especially children, to touch the tool or cable. ƒ Keep them away from your working area. ƒ Take up a working position, in which you are always to the side of the saw blade outside of the cutting level. ƒ Only begin cutting when the saw blade has reached the required speed. ƒ Do not overload the machine! You work better and safer in the given performance range. ƒ Only operate the machine with complete and correctly attached safety equipment and do not alter anything on the machine that could impair the safety. ƒ Do not used cracked saw blades or those that have changed shape. ƒ Only use well sharpened saw blades, as blunt saw blades not only increase the risk of throw-back errors, but also load the motor. ƒ Do not use saw blades made of high-alloy high-speed tool steel (HSS), because this steel is hard and brittle, only tools in accordance with EN 847 – 1 may be used. The use of other tools and other accessories can signify a risk of injury for you. ƒ Use the installed splitting wedge. It is set in the works so that its distance from the toothed ring above the table must

not be more than 5 mm.

ƒ Do not use the saw for unsuitable purposes (see 'Normal intended use'). ƒ When longitudinally cutting narrow workpieces (distance between the saw blade and the parallel rip fence less than 120 mm), use the pushstick. (see working instructions). ƒ To push narrow workpieces against the parallel rip fence, use a pushstick. Î Pushsticks can be purchased in retail outlets. ƒ Do not use defective pushsticks. ƒ The upper saw blade guard must always be used. It must be adjusted so that the toothed ring is covered except for the part required for machining the workpiece. ƒ Ensure that cut off pieces are not caught up by the saw blade and projected away. ƒ Do not remove splinters, chips and waste from the hazardous area of the saw blade by hand. ƒ It is not permissible to use wobble devices and groove milling tools. ƒ Cutting logs with the standard feed guides is not permissible. When cutting logs, use a special device, which secures the workpiece on both sides of the saw blade against turning.

ƒ Design of the connection cable according to IEC 60 245 (H 07 RN-F) with a core cross-profile section of at least − 1.5 mm2 for cable lengths up to 25m − 2.5 mm2 for cable lengths over 25m ƒ Protect yourself against an electric shock. Avoid touching earthed parts with your body. ƒ 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. ƒ Regularly check the saw cable and if damaged, have it renewed by a recognised skilled electrician. ƒ Regularly check the extension cables and replace them if they are damaged. ƒ Do not use any defective connection cables. ƒ When working outdoors, only use extension cables especially approved and appropriately labelled for outdoor use. ƒ Do not set up any provisional electrical connections. ƒ Never bypass protective devices or deactivate them. 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. 20

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, accessories and special accessory 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.

Compare the voltage given on the machine model plate e.g. 230 V with the mains voltage and connect the saw to the relevant and properly earthed plug current motor: L Alternating Use a shockproof plug, mains voltage 230 V with residual current circuit breaker and 10 A inert fuses.

Preparing for commissioning

L Use the connection or extension cable according to IEC 60 245 (H 07 RN-F) with a core cross-profile section of at least ƒ 1.5 mm2 for cable lengths up to 25m ƒ 2.5 mm2 for cable lengths over 25m

Splitting wedge setting

Fitting and adjusting the transverse stop

The splitting wedge (13) is set in the factory at the correct measurement. The splitting wedge is an important safety device as it prevents the workpiece from recoiling To guarantee the function of the splitting wedge, its distance from the toothed wheel its distance from the teeth of the saw blade above the table must not be more than 5 mm.

The transverse stop supplied can be used as a transverse or mitre stop.

L Make sure that the fences are correctly adjusted. (See "Working instructions") Fit the transverse stop to the saw table plate Push the transverse stop into one of the two grooves on the saw table plate.

Set the cutting height

The cut height can be fully adjusted with the aid of the handwheel (B) from 0 – 76 mm. Set the cutting height 5 mm higher than the material thickness.

Setting the angle Loosen the clamping screw of the transverse stop by turning. You can now set the stop to the required angle. Turn the clamping screw tight again.

Adjust saw blade pitch The saw blade must not be set to the inclined position when the blade is turning. The motor must be switched off first.

Adjusting between 0° - 45°

Fitting and adjusting the longitudinal stop

1. Loosen the clamping screw (A). 2. Turn the handwheel until the required angle is shown (0° - 45°). 3. Hold the handwheel and at the same time, tighten the clamping screw again, to fix the adjusted angle.

L Make sure that the fences are correctly adjusted. (See "Working instructions") Fit the longitudinal stop (C) to the saw table plate.

1. Push the longitudinal stopper (handle with integrated adjusting magnifier) into the guide profile on the bench. 2. Set the required position with the aid of the setting magnifying glass. 3. Press the stopper ruler ( C ) up against the bench and fix the lon-gitudinal stopper by pressing lever ( D ) down.

4. In order to ensure that the stop is actually parallel to the saw blade, measure the distance from the saw blade at the front and rear.
