These safety regulations must be observed when working with the lawn mower. Read the entire instruction manual before using the machine for the first time and keep it in a safe place for future reference. Ensure that you are familiar with the controls and use of the machine. Before initial use, advice should be obtained from the specialist dealer or other technician. The lawn mower should not be operated after the consumption of alcohol, medications which impair reactions, or drugs. Never mow in the vicinity of other persons, particularly children, or animals. Be aware that the user of the machine is responsible for accidents involving other persons or their property. Only give (or lend) the machine to persons who are familiar with this model and how to operate it. Always provide them with the instruction manual. Caution – risk of accident: The lawn mower is intended for private use and only for mowing lawns; its use for other purposes is not permitted and may be dangerous or result in damage to the machine. Due to the physical danger to the user, the lawn mower must not be used, for example, for the following applications (incomplete list): – for trimming bushes, hedges and shrubs, – for cutting creepers, – for the care of lawn roofs and balcony boxes, – for clearing paths (vacuuming, blowing, clearing snow), – for shredding or chopping tree or hedge cuttings, – for levelling earth mounds, e.g. mole hills, – for transporting clippings (except in the grass catcher box provided). Caution – risk of accident: Only use accessories which VIKING has supplied or authorised for use on this machine. Furthermore, modifications to the machine are not permitted. Particular care is required during use in public green spaces, parks, sports fields, along roads and in agricultural and forestry businesses. Caution: Danger to health due to vibrations. Excessive exposure to vibrations can result in damage to the cardiovascular or nervous system, particularly in persons with cardiovascular problems. Please consult a physician if you experience symptoms that may have been caused by vibrational loads. Symptoms of this kind principally affect the fingers, hands or wrists and include (incomplete list): – numbness, –pain, – muscular weakness, – skin discolouration, – unpleasant tingling sensation. Children, persons with impaired physical, sensory or mental faculties or those lacking the appropriate experience, or persons who are not familiar with the instructions, must never be allowed to use the machine. Never allow children under the age of 16 to use the machine.Local regulations may specify a minimum age for users.

Risk of death from suffocation! Packaging material is not a toy - danger of suffocation! Keep packaging material away from children.0478 121 9917 E - EN

Take the weight of the machine into account and use suitable loading aids (loading ramps, lifters) if necessary. Avoid contact with the blade when lifting and carrying the machine. Only transport the machine once the motor has cooled down. Secure the machine and any machine components being transported (e.g. grass catcher box) on the load floor using adequately-dimensioned fastening material (belts, ropes etc.). When transporting the machine, always observe regional legislation, especially regarding load security and the transport of objects on load floors.

Persons who are not familiar with the instruction manual are not permitted to use the machine. Observe the local regulations regarding permitted operating times for gardening power tools. Always wear robust shoes and long trousers when mowing. Never mow barefoot or in sandals. Carefully inspect the complete area on which the machine is to be used and remove any large stones, sticks, wires, bones or other foreign objects which could be thrown up by the machine. Before use, perform a visual check to ensure that the cutting tool, fastening screws and entire cutting unit are in good condition, check particuarly for secure seating, damage and wear (Ö 12.5). Replace all worn or damaged parts before using the machine. Replace any illegible or damaged danger signs and warnings on the machine. Your VIKING dealer has a stock of replacement stickers. Never switch the motor on without a correctly installed blade. Risk of motor overheating. Never use the mower with damaged safety devices, without functioning motor brake or attached safety devices, e.g. without the discharge flap or the grass-catching unit. For safety reasons, always use an undamaged grass catcher box. The switch mechanisms installed in the machine must not be removed or bypassed (e.g. by tying the motorstop lever to the handlebar). Observe the instructions in section "Warning - dangers caused by electrical current" (Ö 4.6).

4.4 Mowing procedure

Keep others, particularly children, and animals out of the danger area. Make sure that others are not endangered. Do not mow at ambient temperatures below +5°C (41°F). Never mow wet grass or mow in the rain. The risk of accidents is higher if the grass is wet (increased danger of slipping for operator). Only mow during the day or when there is enough light. Place the machine on an even surface for start-up. The machine must not be tilted when starting the engine. Exercise care when starting the motor. Observe the instructions in section "Initial operation of the machine" (Ö 11.). Keep your feet a safe distance from the cutting tool. 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. Switch off the motor, – if tilting of the mower is necessary when transporting over surfaces other than grass, – when pushing the mower to and from mowing areas, – before removing the grass catcher box. Always ensure good stability on slopes. Avoid mowing on excessively steep slopes in order to prevent loss of control of the machine. Be particularly careful when changing direction on a slope in order to prevent loss of control of the machine. Only mow at right-angles to the slope and never up or down the slope, in order to avoid being run over by the running lawn mower in the case of loss of control of the machine or of falling. Caution – Risk of stumbling! Be particularly careful when moving backwards and when pulling the lawn mower. Be particularly careful when turning the machine around or pulling it towards you. For safety reasons, the machine must not be used on slopes with an incline of more than 25° (46.6%). Risk of injury:31 DEFRNLITESPTNOSVDAPLSKHUHRCS EN 0478 121 9917 E - EN A slope inclination of 25° corresponds to a vertical height increase of 46.6 cm for a 100 cm horizontal distance. Beware of the work tools running on for several seconds before coming to a standstill. Do not try to examine the blades 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. Never attach any objects to the handlebar (e.g. work clothing). Extension cables must never be wrapped around the handlebar. Regularly check that the blade is securely fastened and is not damaged or worn in any way (Ö 12.5). 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. Avoid switching on the machine repeatedly within a short period of time; in particular avoid "playing" with the start button. Risk of motor overheating. Owing to the voltage fluctuations caused by this machine during the run-up period, other devices connected to the same circuit may be subject to interference in the case of unfavourable power supply conditions. In this case, appropriate steps should be taken (e.g. connection to a different circuit than the one used by the affected device, or operation of the machine using a circuit with a lower impedance). Switch off the motor, disconnect the mains plug and ensure that the cutting tool has come to a complete standstill – before remedying blockages, including those in the discharge chute, – if the cutting tool has hit a foreign object. The cutting tool needs to be checked for possible damage. The lawn mower must not be operated with a damaged or bent blade shaft or motor shaft. Risk of injury through defective parts! – Before you check, clean or carry out work on the mower, e.g. adjusting the cutting height, opening or closing the discharge flap; – If the mower begins to vibrate excessively. In this case, the complete machine, in particular the cutting tool must be checked for possible damage and loose parts. Damaged parts must be replaced prior to further use, loose parts must be fastened/tightened. – Before leaving the machine unattended; – Before lifting, or carrying the machine; – Before transporting the machine. Never lift or carry a mower with the motor running or the mains lead connected. It is not permitted to transport anything or anyone, particularly children, on the machine.

4.5 Maintenance, cleaning, repairs and

storage Before performing any work on the machine, before adjusting or cleaning the mower, or before checking whether the electric cable is entwined or damaged, switch off the mower and disconnect the plug. Always wear thick gloves when carrying out any work on the cutting tool. Allow the machine to fully cool down before storing it in an enclosed space, performing maintenance on it or cleaning it. Perform only those maintenance operations that are described in this instruction manual. Have all other operations carried out by a specialist dealer. VIKING recommends that you have maintenance operations and repairs performed exclusively by a VIKING specialist dealer. VIKING specialist dealers regularly attend training courses and are provided with technical information. If you do not have the necessary expertise or auxiliary equipment, please always contact a specialist dealer. (VIKING recommends VIKING specialist dealers). Only use high quality tools, accessories and spare parts. Otherwise, there may be a risk of accidents resulting in personal injury or damage to the machine.0478 121 9917 E - EN

VIKING recommends the use of genuine VIKING tools, genuine accessories and genuine spare parts. Their properties are optimally adapted to the machine and the user's requirements. Genuine VIKING spare parts can be recognised by the VIKING spare parts number, by the VIKING lettering and, if present, by the VIKING spare parts symbol. On smaller parts, only the symbol may be present. Ensure that all nuts, pins and bolts are securely tightened, so that the machine is in a safe operating condition. Check the grass-catching unit regularly for wear, damage or for loss of functionality. If the cutting tool or the lawn mower hits an obstacle or a foreign object, the motor must be switched off, the plug disconnected, and an inspection performed by a specialist. Replace danger signs and warnings on the machine which have become illegible. Your VIKING dealer has a stock of replacement stickers. The power cable should only be repaired or replaced by authorised electricians. In order to prevent fire hazards, keep the area around the air vents between the motor cover and housing free from e.g. grass, straw, moss, leaves or emerging grease. Components or guards that are removed for maintenance operations must be properly reinstalled immediately. Carefully clean the lawn mower following use. Never use high-pressure cleaners and do not clean the lawn mower under running water (e.g. using a garden hose). Do not use aggressive cleaning agents. These cleaners can damage plastics and metals, impairing the safe operation of your VIKING machine. Check the entire machine for wear or damage on a regular basis, particularly before extended periods when the machine is not in use (over winter). Replace worn or damaged parts to ensure that the machine is always in a safe operating condition. Store the cooled lawn mower safely in a dry, locked place that is inaccessible to children.

4.6 Warning – dangers caused by

electrical current Caution: Danger of electric shock! Particularly important for electrical safety are the mains cable, plug, on/off switch and electric cable. Damaged cables, connectors and plugs, or electric cables that do not conform to regulations must not be used, to prevent any risk of electric shocks. Therefore, check the electric cable regularly for signs of damage or ageing (brittleness). Never use a damaged extension cable. Replace defective cables with new ones and never repair extension cables. Never use the machine if the cables are damaged or worn. Danger of electric shock! Do not connect a damaged cable to the mains and do not touch a damaged cable before disconnecting it from the mains. Danger of electric shock! Damaged cables, connectors and plugs, or electric cables which do not conform with regulations may not be used. Keep the electric cable away from the blade when mowing. Only use extension cables that are insulated against moisture for outdoor use which are suitable for use with the machine (Ö 11.1). Although the drive motor is splashproof, do not use the lawn mower when it is raining or in wet environments. Do not leave the machine unprotected in the rain. Detach electric cables at the plug and socket and not by pulling on the electric cable. Only connect the machine to a power supply that is protected by means of a residual current-operated protective device with a release current of a maximum of 30 mA. Your electrician can provide further information. It must be noted that current fluctuations can damage the lawn mower when the machine is connected to a power generator. Always ensure that the power cables used are adequately protected by a fuse. For reasons of electrical safety, the electric cable must always be correctly installed on the handlebar (Ö 7.2).

Ensure that old machines are properly disposed of. Render the machine unusable prior to disposal. In order to prevent accidents, ensure that you remove the power supply cable or the electric cable from the on/off switch to the motor.33 DEFRNLITESPTNOSVDAPLSKHUHRCS EN 0478 121 9917 E - EN Risk of injury due to the mowing blade! Always store an old lawn mower in a safe place prior to scrapping. Ensure that the machine and the mowing blade are kept out of the reach of children. ME 339 C: ME 339:

8.1 Mono handlebar (ME 339 C)

The ME 339 C lawn mower is equipped with an adjustable telescopic handlebar. 1 Folding down handlebar: Transport position (for cleaning, for space-saving transport and for storage of the machine): ● Set handlebar to minimum height. ● Hold handlebar (1) with one hand and open quick-clamping device (2). ● Fold down handlebar (1) forwards. ● If necessary, quick-clamping device (2) can be closed and the handlebar set to the transport position. Working position (to push machine): ● Fold up handlebar (1) rearwards and hold with one hand. ● Close quick-clamping device (2). ● Quick-clamping device (2) must be sufficiently tightened so that it closes completely and upper handlebar is firmly attached to handlebar console. If necessary, release quick-clamping device again and tighten or loosen screw (3). ● Adjust handlebar height. 2 Height adjustment: The height of the telescopic handlebar is infinitely adjustable: ● Hold upper handlebar (4) with one hand and open quick-clamping device (5). Danger of electric shock! In order to prevent damage to the insulating layer on the handlebar, only press on the cable clips by hand. Do not use any tools (e.g. hammer or screwdriver).

Danger of electric shock! The electric cable must always be attached to the quick-release clamp body and the handlebar console. Some slack must be retained at the adjustment area of the telescopic handlebar at maximum handlebar length (Ö 7.2).

Danger of pinching! The handlebar can fold down or retract when the quick-clamping device is released. For this reason, always hold the handlebar (1) with one hand at its highest point when you open the quick clamping device.35 DEFRNLITESPTNOSVDAPLSKHUHRCS EN 0478 121 9917 E - EN ● Pull or push upper handlebar (4) out of/into lower handlebar to the desired handlebar height. ● Hold upper handlebar (4) with one hand and close quick-clamping device (5). ● Quick-clamping device (5) must be sufficiently tightened so that it closes completely and handlebar is firmly locked in lower handlebar.

8.4 Central cutting height

adjustment Five different cutting heights between 30 mm and 70 mm can be set. Level 1 = lowest cutting height Level 5 = highest cutting height Lawn mowers for Great Britain: Six different cutting heights between 20 mm and 70 mm can be set. Level S = lowest cutting height Level 5 = highest cutting height Setting cutting height: ● Push height adjustment lever (1) away from lawn mower slightly until lever is released from locating lugs (2). ● Increasing cutting height: Raise lawn mower using height adjustment lever (1) (push lever forwards). Decreasing cutting height: Lower lawn mower using height adjustment lever (1) (push lever rearwards). ● Push height adjustment lever (1) towards lawn mower slightly until locating lugs (2) engage in lever. The selected cutting height can be read off at the front locating lug (3).

To ensure a perfect, thick lawn, mow regularly and keep the grass short. Do not cut the lawn too short in hot, dry conditions as it will dry out or burn in the sun and become unsightly. The cutting pattern will be better with a sharp blade than with a blunt one; the blade should therefore be sharpened regularly (VIKING specialist dealer). Danger of pinching! The upper handlebar can be fold down when the rotary handles are released. For this reason, always hold the upper handlebar (2) with one hand at its highest point when you unscrew the rotary handles.

In order to prevent damage, the lowest cutting height must only be used on even lawns (without bumps).

9. Notes on working with the

machine Risk of injury! Untangle any knots in the cable immediately. Guide the electric cable behind you when mowing. Electric cables can be inadvertently cut when mowing and present a tripping hazard. They therefore involve a high accident risk. For this reason, mow so that the electric cable is always visible in the area of grass that has already been cut.0478 121 9917 E - EN

9.2 Mowing on slopes

For safety reasons, the lawn mower must not be used on inclines of more than 25°. A slope inclination of 25° (46.6%) corresponds to a vertical height increase of 46.6 cm for a 100 cm horizontal distance.

9.3 Correct motor load

Do not switch on the lawn mower in tall grass or at the lowest cutting height. The lawn mower load must never cause the motor speed to drop significantly. If the speed drops, select a higher cutting height setting and/or reduce the rate of feed.

9.4 If the mowing blade blocks

Switch off the motor immediately and disconnect the plug. Then eliminate the cause of the fault.

9.5 Thermal motor overload protection

If an overload of the motor occurs during operation, the built-in thermal overload protection device automatically deactivates the motor. Causes for an overload: – mowing excessively high grass or cutting height adjusted too low, – excessive rate of feed, – inadequate cleaning of the cooling air guide (inlet slots), – mowing blade is blunt or worn, – unsuitable or excessively long electric cable – voltage loss (Ö 11.1). Recommencing operation Resume normal operation of the machine following a cooling period of up to 10 min (depending on the ambient temperature) (Ö 11.).

10.1 Two-hand operation

The motor can only be switched on by pressing and holding the start button with the right hand and then pulling the motorstop lever to the handlebar with the left hand.

10.2 Motor run-down brake

When the motorstop lever is released, the mowing blade comes to a complete standstill in less than three seconds. An integrated motor run-down brake shortens the run-down time until the blade stops.

11.1 Electrical connection

Only electric cables which are no lighter than rubber sheathed cables H07 RN- F DIN/VDE 0282 may be used as electric cables. Recommended minimum cross- section: up to 25 m Length: 3 x 1.5 mm² up to 50 m Length: 3 x 2.5 mm² The connectors of the electric cable must be made of rubber or have a rubber cover and conform to the standard DIN/VDE 0620. The mains voltage and mains frequency must correspond to the information on the identification plate and the information contained in the section "Technical specifications" (Ö 18.). The power cable must be adequately protected by a fuse (Ö 18.). This machine is intended for operation with a power supply having a system impedance of Z max at the transfer point (house connection) of maximum

0.49 ohms (at 50 Hz).

Danger of electric shock! Observe the safety instructions in the section "For your safety" (Ö 4.). If using a cable drum, the connection cord must be unwound completely, otherwise electrical resistance may cause loss of power and overheating.37 DEFRNLITESPTNOSVDAPLSKHUHRCS EN 0478 121 9917 E - EN The user must ensure that the machine is only operated with a power supply which meets this requirement. If necessary, this information can be obtained from the local electric power company.

During work, the strain relief prevents any unintentional disconnection of the electric cable and any resulting damage to the mains connection on the machine. For this reason, the electric cable must be fed through the strain relief. ● Form a loop in the electric cable (1) and guide it through the opening (2). ● Then push the loop over the hook (3) and pull it tight.

11.3 Switching on lawn mower

● Press and hold down start button (1). Pull motorstop lever (2) to handlebar and hold. ● Start button (1) can be released once motorstop lever (2) is pressed.

11.4 Switching off lawn mower

● Release motorstop lever (1). Motor and mowing blade come to a stop after a short run-down time.

11.5 Level indicator

The grass catcher box features a level indicator (1) on the upper part of the catcher box. The flow of air that is created by the rotary movement of the mowing blade and is responsible for filling the grass catcher box raises the level indicator (2): The grass catcher box is filled with clippings. When the grass catcher box is full, this flow of air is reduced and the level indicator drops (3): ● Empty filled grass catcher box (Ö 11.6).

11.6 Emptying grass catcher box

● Switch off motor (Ö 11.4) and detach grass catcher box (Ö 8.3). ● Open grass catcher box at tab (1) and open upper part of the grass catcher box (2) upwards. ● Hold grass catcher box by handles in upper part of grass catcher box (3) and in lower part of grass catcher box (4) and empty it.

Annual service by the specialist dealer: The lawn mower should be inspected once annually by a specialist dealer. VIKING recommends VIKING specialist dealers.

12.2 Cleaning the machine

Maintenance interval: After each use ● Detach grass catcher box (Ö 8.3). Cleaning position ME 339 C: ● Fold down mono handlebar (Ö 8.1). ● Lift discharge flap (1), tilt mower upwards and set down on handlebar console (2). ● Leave handlebar (3) resting on the ground and fasten in this position with quick-clamping device (4). Cleaning position ME 339: ● Fold down the dual handlebar (Ö 8.2). ● Tilt lawn mower upwards and set down on lower handlebars (5). Notes on cleaning: Clean the machine thoroughly each time it has been used. Care of the machine will protect it against damage and extend its service life. Do not start the motor in high grass or when the mower is set to the lowest cutting height, as this makes starting difficult.

Risk of injury! Observe the safety instructions in the section "For your safety" (Ö 4.).

Risk of injury: Before tipping up the mower, place it on firm, level and flat ground. The machine may tip over when working on it in the cleaning position. Always stand to the side of the machine. Never work in front of or behind the mower. 170478 121 9917 E - EN

Remove dirt from the cooling air guide (inlet slots) between the motor cover and the lower housing to ensure that the motor is adequately cooled. Clean the mowing blade. Clean the underside of the mower with water and a brush. Detach accumulated cutting deposits in the housing and in the ejection chute beforehand using a stick. Never spray water onto motor components, seals, bearing points or electrical parts such as switches. This would result in expensive repairs. If you are unable to remove the dirt with water using a brush or a cloth, VIKING recommends the use of a special cleaner (e.g. STIHL special cleaner).

12.3 Electric motor and wheels

The electric motor is maintenance-free. The wheel bearings are maintenance-free.

12.4 Upper handlebar ME 339

Maintenance interval: Before each use The upper handlebar is coated with a insulating layer. Should this layer become damaged, the upper handlebar must be replaced.

12.5 Mowing blade maintenance

Maintenance interval: Before each use ● Tilt mower upwards into cleaning position (Ö 12.2). ● Clean mowing blade (1) and check it for damage (notches or cracks) and wear; replace if necessary. ● Use a slide calliper (2) to measure blade thickness at 5 points at least. In particular, minimum thickness must also be ensured in the area of the blade wings. ● Place a ruler (3) against the front blade edge and measure permissible grinding. Wear limits: The blade thickness must be at least

1.6 mm at any point.

The cutting edges may not be ground back by more than 5mm during sharpening. If the supplied standard blade is not installed in the lawn mower, but e.g. the mulching blade, which is available as a special accessory, different wear limits apply (see instruction manual Kit 339).

12.6 Removing and installing

mowing blade 1 Removing: ● Use a suitable wooden block (1) to counterhold mowing blade (2). ● Unscrew blade fastening screw (3) and remove mowing blade (2).

Risk of injury: A worn or damaged blade may break off and cause serious injuries. The instructions for blade maintenance must therefore always be observed. In particular, the lawn mower must not be operated if parts of the cutting unit (comprising the mowing blade, blade fastening screw and blade mounting) are damaged or worn. Blades are subjected to differing degrees of wear depending on the location and duration of use. If you use the mower on sandy ground or use it frequently under dry conditions, the blade will be subjected to greater loads and will wear more quickly than the average. Always replace the blade fastening screw (4) when replacing the mowing blade. In order to prevent damage to the blade fastening screw, use a suitable hexagon socket (22 mm) for loosening and tightening.

DEFRNLITESPTNOSVDAPLSKHUHRCS EN 0478 121 9917 E - EN 2 Installing: ● Clean blade contact surface and blade bushing. ● Install mowing blade (2) with curved wings pointing upwards. Locating lugs (4) must be located in bores (5) of mowing blade. ● Use a suitable wooden block (1) to counterhold mowing blade (2). ● Tighten blade fastening screw (3) to a torque of 10 - 15Nm.

12.7 Sharpening mowing blade

VIKING recommends having the mowing blade sharpened by a technician. Operation of the machine is impaired in the case of an incorrectly sharpened blade (incorrect sharpening angle, imbalance etc.). Sharpening instructions: ● Remove mowing blade (Ö 12.6). ● Cool the mowing blade when sharpening, e.g. with water. The blade must not be allowed to display blue colouring, as this would reduce its cutting quality. ● Sharpen the blade evenly to prevent vibrations due to imbalance. ● Observe sharpening angle of 30°. ● After sharpening, remove any sharpening burr at the cutting edge using fine sandpaper if necessary.

12.8 Storage (winter break)

Store the machine in a dry and locked place that is generally free of dust. Make sure that it is kept out of the reach of children. Only store the lawn mower in good operating condition, fold down the handlebar if necessary. Keep all nuts, pins and bolts tightly fastened, replace danger signs and warnings on the machine that have become illegible, check the entire machine for wear and damage. Replace all worn or damaged parts. Any machine faults must be completely remedied prior to storage. Note the following points when storing the lawn mower for long periods (winter break): ● Clean all external parts of the machine with care. ● Thoroughly lubricate/grease all moving parts.

13.1 Carrying and securing lawn

mower Carrying the machine: ● Only lift the lawn mower by the transport handles (1, 2). Always ensure sufficient distance between the mowing blade and your body, particularly your feet and legs. ● Carry the lawn mower using both hands, with one hand at the upper transport handle (2) and the other hand at the lower transport handle (1),

● carry the lawn mower with one hand at the upper transport handle (2). Securing the machine (lashing): ● Secure the lawn mower on the load floor using suitable fastening materials. ● Attach ropes or straps at the handles (1, 2). Lawn clippings should be composted and not disposed of in household waste. Risk of injury: The mowing blade (2) must only be installed as shown. The tabs (6) must face downwards and the curved wings must point upwards. Observe the specified torque of

10 - 15Nm when tightening the

blade fastening screws, as the secure attachment of the cutting tool depends on this. Additionally secure the blade fastening screw (3) with Loctite 243. Risk of injury: Check blade for damage before installing. The blade must be replaced if notches or cracks are identified, if the blade is worn back by 5 mm, or if the blade is thinner than 1.6 mm at any point (Ö 12.5).

Risk of injury: Observe the safety instructions in the section "For your safety" (Ö 4.).
