manual Danger Risk of accident and severe injury to persons. A certain type of behaviour is necessary or must be avoided. Warning Risk of injury to persons. A certain type of behaviour prevents possible or probable injuries. Caution Minor injuries or material damage can be prevented by a certain type of behaviour. Note Information for better use of the machine and in order to avoid possible operating errors.45 DEFRNLITESPTNOSVFIDAPLSLSKTR EN 0478 111 9953 B - EN Texts relating to illustrations: Illustrations relating to use of the machine can be found in the front of this instruction manual. The camera symbol serves to link the figures on the illustration pages with the corresponding text passages in the instruction manual. Models RM 650 VS, RM 655 VS, RM 655 YS, RM 655 RS are equipped with a blade brake clutch (BBC). As with all modern lawn mowers, the blade comes to a stop within a short time as soon as the handlebar is released. However, thanks to the BBC system, the engine continues to run. This function allows the user to use the mower's self-propulsion after the blade has stopped. Moreover, the grass catcher box can be emptied, for example, without having to start the engine again. In order to prevent injuries or damage to the machine, ensure that you are familiar with operation of the BBC system prior to initial use. Note the section "Blade brake clutch (BBC)". (Ö 11.)

These safety regulations must be observed when working with the machine. Read the entire instruction manual before using the machine for the first time. Keep the instruction manual in a safe place for future reference. Observe the operating and maintenance instructions contained in the separate engine instruction manual. These safety precautions are essential for your safety, however the list is not exhaustive. Always use the machine in a reasonable and responsible manner and be aware that the user is responsible for accidents involving third parties or their property. Make sure that you are familiar with the controls and use of the machine. The machine must only be used by persons who have read the instruction manual and are familiar with operation of the machine. The user should seek expert and practical instruction prior to initial operation. The user must receive instruction on safe use of the machine from the vendor or another expert. During this instruction, the user should be made aware that the utmost care and concentration are required for working with the machine. Residual risks persist even if you operate this machine according to the instructions.

5.2 Refilling the tank – handling petrol

Petrol must only be stored in appropriate, tested containers (canisters). Always screw on the fuel tank and canister caps properly and tightly. Defective caps must be replaced for safety reasons. Never use beverage bottles or similar for disposal or storage of fuels and lubricants. Persons, particularly children, could be tempted to drink out of them. Keep petrol away from sparks, naked flames, pilot lights, heat sources, and other ignition sources. Do not smoke! Refill the tank out-of-doors and do not smoke during refilling. Risk of death from suffocation! Packaging material is not a toy - danger of suffocation! Keep packaging material away from children. Danger to life! Petrol is poisonous and extremely inflammable.47 DEFRNLITESPTNOSVFIDAPLSLSKTR EN 0478 111 9953 B - EN Before refilling the tank, stop the engine and allow it to cool. Refilling with petrol must be performed before the engine is started. When the engine is running or is hot, the tank cap must not be removed and the tank must not be refilled with petrol. Do not overfill the fuel tank! To give the fuel room to expand, never fill the fuel tank past the lower edge of the filler neck. Observe the additional instructions in the engine instruction manual. If petrol is spilled, the engine must only be started after the petrol- contaminated area has been cleaned. All attempts at starting must be avoided until the petrol fumes have dispersed (wipe dry). Any spilt fuel must be wiped up immediately. Clothing must be changed if it comes into contact with petrol. Never store the machine with petrol in the tank inside a building. The resulting petrol fumes could come into contact with naked flames or sparks and could be ignited. If it is necessary to drain the tank, this must be done out of doors.

5.3 Battery and charger

Read the engine instruction manual and keep it in a safe place. This instruction manual describes how to safely use the battery and charger. Only use genuine batteries and genuine chargers. Protect the battery and charger against rain and moisture and do not drop. Do not use a damaged or deformed battery or a damaged charger. In particular check the power cable of the charger. Never use a charger with a damaged power cable. Never dismantle or attempt to repair a battery or charger. A defective battery or charger must be replaced. Only connect the charger to a power supply that is protected by means of a residual current-operated protective device with a maximum release current of 30 mA. Your electrician can provide further information. Keep the unused battery away from metal objects (e.g. nails, coins, jewellery). Never short circuit battery connections, do not use metal containers to transport batteries. Fluid may escape from the battery due to improper use – avoid contact! In the case of inadvertent contact, rinse with water. Seek medical attention if the fluid contacts the eyes. Escaping battery fluid can cause skin irritation and burns. For further safety instructions, see http://www.stihl.com/safety-data-sheets

5.4 Clothing and equipment

Always wear sturdy footwear with high-grip soles when working. Never work barefoot or, for example, in sandals. Also always wear sturdy gloves and tie up and secure long hair (headscarf, cap, etc.) when performing maintenance and cleaning work or when transporting the machine. Wear suitable safety glasses when sharpening the mowing blade. Always wear long trousers and tight-fitting clothing when operating the machine. Never wear loose clothes which may become caught on moving parts (control levers) – do not wear jewellery, ties or scarves. Noise is produced when working. Noise can damage the hearing. Wear hearing protection.

5.5 Transporting the machine

Always wear gloves in order to prevent injuries due to sharp-edged and hot components. Do not transport the machine with the engine running. Switch off the engine, let the blades come to a standstill and remove the spark plug socket prior to transport. Only transport the machine once the engine has cooled down and with an empty fuel tank. Use suitable loading aids (loading ramps, lifters). Secure the machine and any machine components being transported (e.g. grass catcher box) on the load floor using fastening material of adequate size (belts, ropes, etc.). Avoid contact with the mowing blade when lifting and carrying the machine. Observe the information in the section "Transport". It describes how to lift and lash the machine. (Ö 15.)0478 111 9953 B - EN

When transporting the machine, always observe regional legislation, especially regarding load security and the transport of objects on load floors. Do not leave the battery inside a vehicle and protect unused batteries against direct sunlight. Lithium-ion batteries must be treated with special care during transport. In particular, short-circuit protection must be ensured. Transport the battery either in the original packaging or in a suitable non-metal transport container.

5.6 Before operation

Make sure that only persons who are familiar with the instruction manual are permitted to use the machine. Remove the packaging material and transport locks before using the machine for the first time. Check the fuel system (particularly visible parts such as e.g. tank, tank cap, hose connections) before operating the machine. In the event of any leaks or damage, do not start the engine – fire hazard! Have the machine repaired by a specialist dealer prior to operation. Observe the local regulations regarding permitted operating times for gardening power tools with combustion engines. Carefully inspect the complete area on which the machine is to be used and remove any stones, sticks, wires, bones and other foreign objects which could be thrown up by the machine. Obstacles (e.g. tree stumps, roots) can be easily overlooked in long grass. For this reason, mark all foreign objects (obstacles) which are hidden in the lawn and cannot be removed before commencing work with the machine. All faulty, worn or damaged parts must be replaced before using the machine. Replace any illegible or damaged danger signs and warnings on the machine. Your STIHL specialist has a supply of replacement stickers and all the other spare parts. Check secure seating of the spark plug socket on the spark plug before using the machine. The machine must only be used in good operating condition. Before each use, check whether: – The machine is properly assembled. – The cutting tool and the entire cutting unit (mowing blade, fastening elements, mowing deck housing) are in good condition. In particular check for secure fastening, damage (notches or cracks) and wear. (Ö 14.3), (Ö 14.12) – The mulch insert is in good condition. – The tank cap is properly attached. – The tank and fuel-carrying parts as well as the tank cap are in good condition. – The safety devices (e.g. motorstop lever, discharge flap, housing, handlebar, protective grille) are in good condition and working properly. – The blade brake clutch is working properly. (Ö 13.1) – The grass catcher box is undamaged and correctly installed; a damaged grass catcher box must not be used. –The battery (RM 650 VE) is not damaged or deformed. – The oil closure screw is properly attached. Carry out any necessary work or consult a specialist dealer. STIHL recommends STIHL specialist dealers.

5.7 During operation

Keep other people out of the danger area. Never work when animals or people, particularly children, are in the danger area. The switch and safety devices installed in the machine must not be removed or bypassed. In particular, never secure the motorstop lever or blade stop lever to the handlebar (e.g. by tying it). Caution – risk of injury! Never put hands or feet on or underneath rotating parts. Never touch the rotating blade. Always keep away from the discharge opening. Always observe the safety distance provided by the handlebar. The handlebar must always be installed correctly and must not be modified. Never operate the machine with the handlebar folded down. Never attach any objects to the handlebar (e.g. work clothing). Only work during the day or with good artificial light. Do not operate the machine in the rain or during thunder storms, particularly when there is a risk of lightning strike. The risk of accidents is higher if the ground is damp due to increased danger of slipping. Particular caution should be exercised49 DEFRNLITESPTNOSVFIDAPLSLSKTR EN 0478 111 9953 B - EN during working in order to prevent slipping. If possible, avoid using the machine when the ground is damp. Exhaust gases: The machine generates poisonous exhaust gases when the engine is running. The gases contain poisonous carbon monoxide, a colourless and odourless gas, as well as other pollutants. The engine must never be operated in closed or poorly ventilated spaces. Starting: Exercise care when starting the machine and observe the instructions contained in the section entitled "Operating the machine" (Ö 13.). Starting the machine in accordance with these instructions reduces the risk of injury. Risk of injury! If the starter rope recoils at speed, the hand and arm will be pulled towards the engine faster than the starter rope can be released. This kickback can result in broken bones, crush injuries and sprains. Keep your feet a safe distance from the cutting tool when starting the machine. The machine must not be tilted during start-up. The self-propulsion lever must not be actuated when starting the engine. RM 650 VS, RM 655 RS, RM 655 VS, RM 655 YS: The mowing blade must not be engaged when starting the engine. Do not start the engine if the discharge chute is not covered by the discharge flap or the grass catcher box. Working on slopes: Always work across and back on slopes, never up and down. If the user loses control when mowing up and down, there is a risk of being run over by the machine. Be particularly careful when changing direction on a slope. Always ensure good stability on slopes and avoid mowing on excessively steep slopes. For safety reasons, the machine must not be used on slopes with an inclination of more than 25° (46.6%). Risk of injury! A slope inclination of 25° corresponds to a vertical height increase of 46.6 cm for a 100 cm horizontal distance. In order to ensure an adequate oil supply for the engine, the information in the accompanying engine instruction manual must be additionally observed when using the machine on slopes. Working: Do not try to examine the blade while the lawn mower is operating. Never open the discharge flap and/or remove the grass catcher box when the mowing blade is running. Rotating blades can cause injury. Only operate the machine at walking speed – never run when working with the machine. Working quickly with the machine increases the risk of injury due to stumbling, slipping, etc. Only guide the machine using the handlebar – never use the levers to move the lawn mower. (Ö 12.1) Be particularly careful when turning the machine around or pulling it towards you. Risk of stumbling! Use the machine with great care when working near slopes, terraces, ditches and embankments. In particular, ensure that you maintain sufficient distance to such danger areas. Objects hidden in the turf (lawn sprinkler systems, posts, water valves, foundations, electrical wires, etc.) must be avoided. Never run over any such foreign objects. Beware of the cutting tool running on for several seconds before coming to a standstill. Switch off the engine, allow the work tool to come to a complete standstill, detach the spark plug socket and additionally remove the battery (with RM 650 VE), Danger to life through poisoning! In the case of nausea, headache, impaired vision (e.g. decreasing field of view) hearing disorder, dizziness, decreasing power of concentration, stop working immediately. These symptoms may be caused by excessively high exhaust gas concentrations. Risk of injury! Never place your hands or feet above, underneath or on rotating parts.0478 111 9953 B - EN

– before leaving the machine unattended, – before re-filling the tank. Allow the engine to cool down before filling the tank. Fire hazard! – before remedying blockages, including those in the discharge chute, – before lifting or carrying the machine, – before transporting the machine, – before carrying out any work on the mowing blade, – before checking or cleaning the machine or before carrying out any other work (e.g. folding down the handlebar, installing and removing the mulching key) on it, – after hitting a foreign object or if the lawn mower begins to vibrate excessively. In these cases check the machine, in particular the cutting unit (blade, blade shaft, blade fastening) for damage and carry out the necessary repairs before restarting and working with the machine. Stop the engine and disengage the mowing blade: – When pushing the machine to and from the area to be worked. – Before pushing the machine onto an area not covered with grass. – Before opening the discharge flap or removing the grass catcher box. – When the machine has to be tilted for transportation. – Before adjusting the cutting height.

5.8 Maintenance and repairs

Before beginning cleaning, adjustment, repair and maintenance operations: ● Park the machine on firm and level ground ● Stop the engine and allow it to cool down ● Detach the spark plug socket. Caution – risk of injury! Keep the spark plug socket away from the spark plug; an inadvertent ignition spark may result in fires or electric shocks. Inadvertent contact between the spark plug and the spark plug socket may result in unwanted starting of the engine. RM 650 VE: Additionally remove the battery. Allow the machine to cool down before working on or around the engine, exhaust manifold or muffler in particular. Temperatures of 80° C and above can be reached. Danger of burns! Direct contact with engine oil can be dangerous. Engine oil must not be spilled. STIHL recommends leaving the task of topping up engine oil or performing engine oil changes to a STIHL specialist dealer. Cleaning: The complete machine must be cleaned thoroughly following use. (Ö 14.2) Empty the fuel tank (e.g. by running it empty) before placing the machine in the cleaning position. Remove accumulated clipping deposits using a stick. Clean the underside of the mower with water and a brush. Never use high-pressure cleaners and do not clean the machine under running water (e.g. using a garden hose). Do not use aggressive cleaning agents. These can damage plastics and metals, impairing the safe operation of your STIHL machine. In order to prevent fire hazards, keep the area around the air vents, cooling ribs and the area of the exhaust free from e.g. grass, straw, moss, leaves or escaping grease. Maintenance operations: Only maintenance operations described in this instruction manual may be carried out. Have all other work performed by a specialist dealer. Risk of injury! Strong vibration is normally an indication of a fault. In particular, the lawn mower must not be operated with a damaged or bent crankshaft or mowing blade. If you do not have the appropriate expertise, have the necessary repairs carried out by a specialist dealer (STIHL recommends STIHL specialist dealers). Risk of injury due to the mowing blade! Pulling the recoil starter rope starts the work tool rotating. Always ensure sufficient distance between the mowing blade and your body, particularly your hands and feet, when you pull the recoil starter rope.51 DEFRNLITESPTNOSVFIDAPLSLSKTR EN 0478 111 9953 B - EN If you do not have the necessary expertise or auxiliary equipment, please always contact a specialist dealer. STIHL recommends that you have maintenance operations and repairs performed exclusively by a STIHL specialist dealer. STIHL specialist dealers regularly attend training courses and are provided with technical information. Only use tools, accessories or attachments approved for this machine by STIHL or technically identical parts. Otherwise, there may be a risk of accidents resulting in personal injury or damage to the machine. If you have any questions, please consult a specialist dealer. The characteristics of original STIHL tools, accessories and spare parts are optimally adapted to the machine and the user's requirements. Genuine STIHL spare parts can be recognised by the STIHL spare parts number, by the STIHL lettering and, if present, by the STIHL spare parts symbol. On smaller parts, only the symbol may be present. For safety reasons, fuel-carrying components (fuel line, fuel cock, fuel tank, tank cap, connections, etc.) must be checked regularly for damage and leaks and replaced by a technician if necessary (STIHL recommends STIHL specialist dealers). Always keep warning and information stickers clean and readable. Damaged or missing stickers must be replaced by new, original plates from your STIHL specialist dealer. If a component is replaced with a new component, ensure that the new component is provided with the same stickers. Only perform work on the cutting unit when wearing thick work gloves and exercising extreme care. Ensure that all nuts, pins and screws (in particular the blade fastening screw) are securely tightened so that the machine is in a safe operating condition. Replace damaged exhaust silencers and guard plates. Check the complete machine and the grass catcher box for wear or damage on a regular basis, particularly before extended periods when the machine is not in use (e.g. over winter). For safety reasons, worn or damaged parts must be replaced immediately to ensure that the machine is always in a safe operating condition. Never alter the basic setting of the engine or run at excessive engine speeds. Components or guards that are removed for maintenance operations must be properly reinstalled immediately.

5.9 Storage for prolonged periods

without operation Allow the engine to cool before storing the machine in an enclosed space. Ensure that the machine is protected from unauthorised use (e.g. by children). Store the machine with empty fuel tank and the fuel reserve in a lockable and well- ventilated room. Never store the machine with petrol in the tank inside a building. The resulting petrol fumes could come into contact with naked flames or sparks and could be ignited. If the tank has to be emptied (e.g. to store the machine before the winter break), this should only be done out of doors (e.g. by running the tank empty). Thoroughly clean the machine before storage (e.g. winter break). Store the machine on a suitable surface and only standing on its wheels – secure it against rolling away. Only store the machine with the spark plug socket disconnected. RM 650 VE: Before storing the machine, remove the battery and store it separately from the machine as well as protected from unauthorised use (e.g. by children). Store the machine in good operational condition. Allow the machine to cool down completely before covering it. Store the machine on a level surface so that it cannot unintentionally roll away.

Waste products such as used engine oil or fuel, used lubricants, filters, batteries and similar wearing parts can be harmful to people, animals and the environment, and must consequently be disposed of properly. Consult your recycling centre or your specialist dealer for information on the proper disposal of waste products. STIHL recommends STIHL specialist dealers. Ensure that old machines are properly disposed of. Render the machine unusable prior to disposal. In order to prevent accidents, remove the ignition lead, empty the fuel tank and drain the engine oil in particular.0478 111 9953 B - EN

The battery must be disposed of separately from the machine. Ensure that batteries are disposed of safely and in an environmentally friendly manner. Risk of injury due to the mowing blade!

10.2 Motorstop lever

Models RM 650 T, RM 650 V, RM 650 VE, RM 655 V are equipped with a motorstop device. The engine stops when motorstop lever (1) is released during running operation. The engine and blade come to a standstill within 3 seconds. Measuring the run-on time Following engine start-up, the blade rotates and a wind noise is audible. The run-on time corresponds to the duration of the wind noise after the engine stops. This can be measured using a stopwatch. Models RM 650 VS, RM 655 RS, RM 655 VS, RM 655 YS are equipped with a blade brake clutch (BBC). Two-hand operation: The mowing blade can only be engaged as follows with the engine running: ● Press blade stop lever (1) with one hand and, while keeping it pressed, pull blade clutch lever (5) upwards with the other hand and allow it to engage. (Ö 13.6) Integrated blade run-down brake: When the blade stop lever is released (or after releasing the handlebar), the mowing blade is disengaged and braked to a standstill within a maximum of 3 seconds, while the engine continues to run. (Ö 13.7) A perfect, thick lawn is achieved by – Mowing at low driving speeds. – Mowing regularly and keeping the grass short. – Not cutting the lawn too short in hot, dry conditions as it will be burnt by the sun and become unsightly. – Using a sharp mowing blade – mowing blade should therefore be sharpened regularly (specialist dealer). – Changing the cutting direction regularly.

12.1 Working area for operator

● For safety reasons, the operator must stay within the working area behind the handlebar when starting the engine and when the engine is running. Always observe the safety distance provided by the handlebar.

Risk of injury! If a safety device is found to be defective, the machine must not be operated. Consult a specialist dealer; STIHL recommends STIHL specialist dealers.

Risk of injury! If the run-on time of the blade exceeds this delay, stop using the machine and take it to your specialist dealer.

11. Blade brake clutch (BBC)

Risk of injury! Operation of the blade brake clutch must be checked before each use. (Ö 13.1) For safety reasons, the lever must never be disabled, e.g. by tying it to the handlebar.

12. Notes on working with

12.2 Lawn mower with lawn roller

The model RM 655 RS is equipped with a two-part drive roller on the rear axle. This permits accurate mowing along lawn edges or around plants. The grass is also rolled in the direction of travel, creating a characteristic striped lawn pattern.

The lawn mower is equipped with a multi- blade and can be used as a mulching mower or rear discharge mower as well as a grass collector. ● To use the machine as a mulching mower, install the mulch insert. (Ö 8.5) ● For use as a rear discharge mower or grass collector (with grass catcher box), remove the mulch insert from the machine. (Ö 8.5)

12.4 How should mulching be

performed? Mulching is only possible with the models RM650T, RM650V, RM650VE, RM 650 VS, RM 655 V, RM 655 VS, RM 655 YS. A cutting height between 4 and 7 should be selected for mulching, as this is the most suitable height for shredding the grass. If the cutting height is too low, the mower housing may become clogged, resulting in blockage of the mowing blade It is important to select the correct operating speed and cutting height for mulching to allow the mowing blade to achieve optimal grass shredding and a good cutting pattern. In high grass, it is advisable to work in several stages and in the higher cutting height settings. Mulching should not be performed when the grass is too high or wet.

13.1 Checking the blade brake clutch

Operation of the blade brake clutch must be checked three times before starting work. ● Engage the mowing blade with the engine running. (Ö 13.6) A running mowing blade generates a clearly audible wind noise. ● Disengage the mowing blade (release the handlebar). (Ö 13.7) The blade brake clutch disengages the mowing blade from the engine drive and brakes it. This procedure is accompanied by stopping of the wind noise and lasts a maximum of 3 seconds. No wind noise must be audible when the blade is stopped. The blade brake time can be measured using a stopwatch.

13.2 Starting the engine
