2 Introduction 2.4 Identification of the machine Nameplate data The nameplate lists information that uniquely identifies your machine. This information is needed to order spare parts and when requesting additional technical information. f Enter the information of your machine into the following table: Item 8 Designation 1 Group and type 2 Construction year 3 Machine no. 4 Version no. 5 Item no.
BTS 630, 635 3 3.1 3 Safety Safety Principle State of the art This machine has been constructed with state-of-the-art technology according to the recognized rules of safety. Nevertheless, when used improperly, dangers to the life and limb of the operator or to third persons or damage to the machine or other materials cannot be excluded. Proper use The machine must only be used for the following purposes: Cutting concrete, stone and ceramic. Cutting metal. Cutting asphalt.
3 Safety BTS 630, 635 Structural modifications Never attempt to modify the machine without the written permission of the manufacturer. To do so will endanger your safety and the safety of other people! In addition, this will void the warranty and the liability on behalf of the manufacturer. Especially the following are cases of structural modifications: Opening the machine and the permanent removal of components from Wacker Neuson.
BTS 630, 635 3 Safety Malfunctions If you detect a malfunction, you must shut down and secure the machine immediately. Eliminate the malfunctions that impair safety immediately! Have damaged or defective components replaced immediately! For further information, refer to chapter Troubleshooting. Spare parts, accessories Use only spare parts from Wacker Neuson or such that are equivalent to the original parts in design and quality. Only use accessories from Wacker Neuson.
3 Safety BTS 630, 635 Operator's controls Always keep the operator's controls of the machine dry, clean and free of oil or grease. Operating elements such as ON/OFF switch, throttle levers etc. may not be locked, manipulated or changed without authorization. Checking for signs of damage Inspect the machine when it is switched off for any signs of damage at least once per work shift. Do not operate the machine if there is visible damage or defects. Have any damage or defects eliminated immediately.
BTS 630, 635 3 Safety Work recommendations Please observe the recommendations below: 3.3 Work only if you are in a good physical condition. Work attentively, particularly as you finish. Do not operate the machine when you are tired. Carry out all work calmly, circumspectly and carefully. Never operate the machine under the influence of alcohol, drugs or medication. This can impair your vision, reactions and your judgment. Work in a manner that does not endanger others.
3 Safety BTS 630, 635 Ear protection This machine generates noise that exceeds the country-specific permissible noise levels (individual rating level). It may therefore be necessary to wear ear protection. You can find the exact value in the chapter Technical Data. When wearing ear protection while working, you must pay attention and exercise caution because your hearing is limited, e.g. in case someone screams or a signal tone sounds. Wacker Neuson recommends that you always wear ear protection.
BTS 630, 635 3 Safety Transporting the machine Secure the machine on the transport device against tilting, falling or slipping. Restarting Machines, machine parts, accessories or tools that were detached for transport purposes must be re-mounted and fastened before restarting. Only operate in accordance with the operating instructions. 3.5 Operating safety Explosible environment Never operate the machine in a potentially explosive environment.
3 Safety BTS 630, 635 Starting the machine Observe the safety information and warning notices located on the machine and in the operator's manual. Never attempt to start a machine that requires maintenance or repairs. Start the machine as described in the operator's manual. Vertical stability Always make sure that you stand firmly when working with the machine. Do not work with the machine on ladders or scaffolding. Do not use the machine at heights above shoulder height.
BTS 630, 635 3 Safety Storage location After operation, allow the machine to cool and then store it in a sealed-off, clean and dry location protected against frost and inaccessible to children. Vibrations When manually operated machines are intensively used, long-term damage caused by vibrations cannot be precluded. Observe the relevant legal instructions and guidelines to minimize vibration stress. Details on vibration stress associated with the machine can be found in the chapter Technical Data.
3 Safety BTS 630, 635 Dangers during operation Combustion engines can be dangerous, particularly during operation and when refueling. Read and follow all safety instructions. Otherwise there is a risk of personal injury and/or damage to property! Do not start the engine near spilt fuel or if you smell fuel – this may cause an explosion! Remove the machine from such areas.
BTS 630, 635 3 Safety Operation in closed rooms In closed or partially closed rooms such as tunnels, drifts or deep trenches, ensure sufficient ventilation by, for example, providing a powerful exhaust air fan. Danger of poisoning! Do not inhale exhaust fumes. They contain toxic carbon monoxide that can lead to unconsciousness or death. Caution with hot parts Do not touch any hot parts such as the engine block or exhaust muffler during operation or directly afterwards.
3 Safety 3.8 BTS 630, 635 Safety during cut-off saw operation Kickback If the upper quarter of the cutting blade is applied to a material, the machine can be flung back toward the operator with great force. The machine and the rotating cutting blade can cause severe injury. To prevent kickback, follow these rules: While working, as a rule hold the machine on the provided handles with both hands. Do not use the upper quarter of the cutting blade to cut.
BTS 630, 635 3 Safety Preventing pinching Prevent the cut from becoming constricted and pinching the cutting blade during the cutting process. Support the material such that the cut remains open and does not become constricted during the entire cutting process. Notes regarding cutting blades The cutting blade must be suitable for use with the cut-off saw. The cutting blade must be suitable for the material to be cut.
3 Safety BTS 630, 635 Belt guard Never operate the machine without a belt guard! Exposed V-belts and belt pulleys are dangerous and can cause serious injuries if they pull in any part of your body or if parts are ejected. Protective hood Never operate the machine without a protective hood. The protective hood performs the following functions: Protects the operator from the rotating cutting blade. Diverts workpiece particles and sparks or chips from a damaged cutting blade away from the operator.
BTS 630, 635 3 Safety Do not stand in the machine's swing area Hold and guide the machine such that no body parts are in the machine's swing area. Securing the material Before cutting, secure the material so that it does not slide away or tip over. Do not ever secure the material with your foot. Remove foreign objects before cutting Before cutting, remove foreign objects such as nails, etc. from the cutting area.
3 Safety 3.9 BTS 630, 635 Maintenance Maintenance work Service and maintenance work must only be carried out to the extent described in these operating instructions. All other procedures must be performed by your Wacker Neuson representative. For further information, refer to chapter Maintenance. Switching off the engine Before carrying out care or maintenance work, switch off the engine and allow it to cool down. For gasoline powered engines, you must pull off the spark plug cap.
