Symptoms of this kind principally affect the fingers, hands or wrists and include (incomplete list):

- numbness,

- p a i n ,

– muscular weakness,

– skin discolouration,

– unpleasant tingling sensation.

4.2 Refilling the tank – handling petrol

Danger to life!

Petrol is poisonous and extremely inflammable.

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.

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 fill the fuel tank completely, but fill to approx. 4 cm below the edge of the filler neck so that the fuel has room to expand.

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.

4.3 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.

4.4 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 on the load floor using adequately dimensioned fastening materials (straps, 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. ( 13.)

When transporting the machine, always observe regional legislation, especially regarding load security and the transport of objects on load floors.

4.5 Before operation

Make sure that only persons who are familiar with the instruction manual are permitted to use the machine.

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 or electric motors.

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.

Defective and all other worn or damaged parts must be removed before using the machine. Replace any illegible or damaged danger signs and warnings on the machine. Your VIKING 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. ( 12.2)
– 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, housing, handlebar, protective grille) are in good condition and working properly.
– The oil cap is properly attached.

Carry out any necessary work or consult a specialist dealer. VIKING recommends VIKING specialist dealers.

4.6 Working with your machine

Never work when animals or persons, 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 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 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 exercised during working in order to prevent slipping. If possible, avoid using the machine when the ground is damp.

Exhaust gases:

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.

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 and observe the instructions contained in the section entitled "Initial operation of machine". (⇔ 11.)

Keep your feet a safe distance from the cutting tool.

The machine must not be tilted during start-up.

The self-propulsion lever must not be pressed when starting the engine.

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.

max. 25° 100 46,6

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:

Risk of injury!

Never place your hands or feet above, underneath or on rotating parts.

Do not try to examine the blade while the lawn mower is operating. 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.

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 rubbish dumps, 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.

STOP

Switch off the engine, allow the work tool to come to a complete

standstill and detach the spark plug socket

– 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 mowing deck housing,

– 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) 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.

Risk of injury!

Strong vibrations are generally an indication of a fault. In particular, the lawn mower must not be operated with a damaged or bent blade shaft or mowing blade. If you do not have the appropriate expertise, have the necessary repairs carried out by a specialist dealer (VIKING recommends VIKING specialist dealers).

Switch off the engine:

• When pushing the machine to and from the area to be worked.
  – Before pushing the machine onto an area not covered with grass.
• When the machine has to be tilted for transportation.
  – Before adjusting the cutting height.

4.7 Maintenance and repairs

Before beginning cleaning, adjustment, repair and

maintenance operations, park the machine on firm, level

ground, stop the engine, allow it to cool down and detach the spark plug socket.

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.

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. VIKING recommends leaving the task of topping up engine oil or performing engine oil changes to a VIKING specialist dealer.

Cleaning:

The complete machine must be cleaned thoroughly following use. ( 12.1)

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 VIKING 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.

If you do not have the necessary expertise or auxiliary equipment, please always contact 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.

Only use tools, accessories or attachments approved for this machine by VIKING 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 VIKING tools, accessories and spare parts 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.

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 (VIKING recommends VIKING specialist dealers).

Always keep warning and information stickers clean and readable. Damaged or missing stickers must be replaced by new, original plates from your VIKING 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.

Check the entire machine 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.

4.8 Storage for prolonged periods without operation

Allow the engine to cool before storing the machine in an enclosed space.

Allow the machine to cool down completely before covering it.

Store the machine with empty fuel tank and the fuel reserve in a lockable and well-ventilated room.

Ensure that the machine is protected from unauthorised use (e.g. by children).

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).

Only store the machine with the spark plug socket disconnected.

Store the machine in good operational condition.

4.9 Disposal

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. VIKING recommends VIKING 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.

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 particularly the mowing blade are kept out of the reach of children.

Recommendation: Fresh good quality fuels, Unleaded petrol.

Please consult the engine instruction manual for details on the fuel quality (octane rating).

8. Controls

8.1 General

Risk of injury!

Observe the safety instructions in the section "For your safety" ( 4.).

- Place the machine on level and firm ground when performing all the operations described.

8.2 Folding down the handlebar

The handlebar can be folded down for space-saving transport and storage of the mower.

Danger of pinching!

The handlebar can fold down uncontrollably when the quick-clamping devices are released.

For this reason, always hold the handlebar with one hand when you release the fastening.

• Stop the engine and remove the spark plug socket. ( 11.2)
• Detach the recoil starter rope. (⇒ 8.3)
• Open the left and right quick-clamping devices (1) and carefully fold the handlebar (2) downwards to the front.

8.3 Attaching and detaching the recoil starter rope

Attaching

• Detach the spark plug socket from the engine.
• Press the motorstop lever (1) to the handlebar and hold.
• Slowly pull out the recoil starter rope (2).
• Release the motorstop lever (1) and attach the recoil starter rope (2) to the rope guide (3).
• Connect the spark plug socket.

Detaching

- Detach the spark plug socket from the engine.

- Detach the recoil starter rope (2) from the rope guide (3).

8.4 Adjusting the cutting height

Risk of injury!

Stop the engine before adjusting the cutting height.

There are 4 different cutting height settings from 28 mm to 85 mm.

Level 1 = lowest cutting height

Level 4 = highest cutting height

Risk of injury!

The setting on the front and rear axles must be identical.

1 Setting the rear cutting height

• Set the required cutting height at the rear axle (1).
  For this purpose, support the machine with one hand and move the rear axle to the desired level on one side first and then on the other.
  Ensure that the left and right sides are at the same level (rear axle parallel to the housing).

2Setting the front cutting height

• MB 2 RT:
  Push the cutting height adjustment lever (2) outwards, move to the desired level and allow it to engage.
• MB 2 RC, MB 2 R:
  Set the required cutting height at the front axle (3).
  For this purpose, support the machine with one hand and move the front axle to the desired level on one side first and then on the other. Ensure that the left and right sides are at the same level (front axle parallel to the housing).

9. Safety devices

The machine is equipped with several safety devices for safe operation and for the prevention of improper use.

Risk of injury

If a safety device is found to be defective, the machine must not be operated. Consult a specialist dealer; VIKING recommends VIKING specialist dealers.

9.1 Motorstop lever

The lawn mower is equipped with a motorstop device.

The engine stops when the motorstop lever is released during running operation. The engine and blade come to a standstill within 3 seconds.

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.

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.

10. Notes on working with the machine

10.1 General information on mulching

During mulching, the cut grass is chopped up several times through a special air flow guidance system in the mower blade area and then blown back into the turf. The clippings remain on the lawn.

Benefits

The decomposing clippings return organic nutrients to the soil, serving as a natural fertiliser.

Advantages

Emptying the grass catcher box and disposal of the clippings are dispensed with. Weed growth is slowed down and significant amounts of fertilizer are saved.

10.2 When is mulching permissible?

VIKING recommends mulching only when the lawn is dry and the grass is not too high.

If the grass is too high, the lawn should be mowed in two stages. ( 10.3)

Caution

If the cutting height is too low or the grass is wet, the housing may become clogged, blocking the blade!

10.3 How should mulching be performed?

Requirements for good mulching results:

• Set the optimal cutting height: A third of the grass height should be cut.
  – Use well sharpened blades.
• Vary the mowing direction and ensure that the mowing strips overlap.

Working method in high grass

In high grass, the lawn should be cut in two stages.

First stage:

The lawn is mowed at the maximum cutting height.

Second stage:

12 to 24 hours after the first stage, mulch the lawn to the desired grass height at right angles to the first mowing direction.

10.4 How often should mulching be performed?

To ensure a perfect, thick lawn, mulch regularly and keep the grass short.

Main growth period:

Spring:

mulch at least twice per week.

Summer and autumn:

mulch at least once per week.

11. Operating the machine

11.1 Starting the engine

Avoid damage to the machine. Do not start the engine in tall grass or at the lowest cutting height. This makes starting difficult. Thanks to the fixed throttle setting, the engine always operates at the optimum working speed after starting.

Starting procedure when the engine is cold:

• Only for MB 2 R:
  Press the primer (1) three times.
• Press the motorstop lever (2) to the handlebar and hold.
• Slowly pull out the recoil starter rope (3) to the point of compression resistance. Then pull vigorously and quickly to arm's length. Slowly return the recoil starter rope (3) so that it is rolled up again.
  Repeat the procedure until the engine starts.

Starting procedure when the engine is warm:

Avoid damage to the machine.

The primer must no longer be pressed when the engine is warm. It should be remembered, however, that the engine can cool down rapidly in very cold weather.

• The starting procedure is the same as when the engine is cold.
  It is not necessary to press the primer (1).

Only for MB 2 R:

11.2 Stopping the engine

- Release the motorstop lever (1).

The engine and blade come to a standstill within 3 seconds.

11.3 Self-propulsion (MB 2 RT)

Note

The MB 2 RT model features front-wheel drive.

1 Switching on self-propulsion

• Start the engine. (⇒ 11.1)
• Pull the self-propulsion lever (1) to the handlebar and hold.

Self-propulsion is activated and the lawn mower moves forwards.

2Switching off self-propulsion

- Release the self-propulsion lever (1).

Self-propulsion is deactivated and the lawn mower comes to a standstill.

The engine and blade continue to run.

12. Maintenance

Risk of injury!

Carefully read the section "For your safety" ( 4.), particularly the subsection "Maintenance and repairs" ( 4.7), and follow all safety instructions exactly before performing any maintenance or cleaning operations on the machine.

Allow the machine too cool and detach the spark plug socket before performing any maintenance or cleaning operations.

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

12.1 Cleaning the machine

Maintenance interval:

After each use.

Risk of injury!

Stop the engine, allow the machine to cool and detach the spark plug socket.

Empty the fuel tank (run empty) before placing the machine in the cleaning position.

Place the machine in the cleaning position.

- Open the quick-clamping devices (1) and fold down the handlebar (2) to the rear.

- Lift up the machine at the front and place in the cleaning position as shown.

12.2 Checking blade wear

Maintenance interval:

Before each use.

Risk of injury!

Blades are subjected to differing degrees of wear depending on the location and duration of use. If you use the machine 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.

A worn blade may break off and cause serious injuries. The instructions for blade maintenance must therefore always be observed.

Checking procedure

• Place the machine in the cleaning position. ( 12.1)
• Clean the blade (1) and check it for damage (notches or cracks).
• Use a slide calliper (2) to measure the blade thickness (A) at several points.
• Measure the permissible grinding (B). Place a ruler (3) against the front blade edge as shown for this purpose.

Wear limits

The blade thickness (A) must be at least 2 mm at any point. The most important points are marked in the illustration.

The cutting edges must not be ground back by more than 5 mm – distance (B) (permissible grinding) during sharpening.

12.3 Sharpening the mowing blade

If you do not have the necessary expertise or auxiliary equipment, we recommend that you have the blade sharpened by a specialist dealer. Operation of the machine is impaired in the case of an incorrectly sharpened blade (incorrect sharpening angle, imbalance etc.).

Sharpening instructions

• Remove the mowing blade. (⇒ 12.4)
• Cool the mowing blade during sharpening, e.g. with water. The blade must not be allowed to display blue colouring, as this would reduce its cutting quality.
• Sharpen blades evenly to prevent vibration due to imbalance.
• Observe a sharpening angle of 30^ .
• Observe the wear limits (⇒ 12.2).

12.4 Removing and installing the mowing blade

Risk of injury! Always wear gloves.

The mowing blade must be replaced if notches or cracks are detected or if a wear limit is reached ( 12.2).

Removing

• Hold the mowing blade (1) and loosen the blade fastening screw (2).
• Remove the blade fastening screw (2), retaining washer (3) and mowing blade (1).

Installing

• Clean the blade contact surface and blade bushing (4).
• Secure the blade fastening screw (2) with Loctite 243.
• Place the mowing blade (1) on the blade bushing (4) as shown.
• Position the retaining washer (3) as shown and tighten with the blade fastening screw (2) to 60 - 65 Nm.

Risk of injury!

The prescribed tightening torque for the blade fastening screw must be observed.

The retaining washer (3) must be replaced each time the blade is installed.

The blade fastening screw (2) must be renewed each time the blade is replaced.

12.5 Engine

Maintenance interval:

See engine instruction manual.

General information:

Observe the operating and maintenance instructions contained in the attached engine instruction manual.

To achieve a long service life, it is always particularly important to maintain a sufficient level of oil and to change the oil and air filter regularly.

The recommended oil change intervals as well as information on engine oil and oil capacities can also be found in the engine instruction manual.

The cooling ribs must always be kept clean to ensure that the engine is adequately cooled.

12.6 Wheels and gearbox

The wheel bearings are maintenance-free.

The gearbox is maintenance-free.

12.7 Storage (winter break)

Note the following points when storing the machine for long periods (winter break):

• Clean all external parts of the machine with care.
• Thoroughly lubricate/grease all moving parts.
• Empty the fuel tank and carburettor (e.g. by running empty).
• Unscrew the spark plug (see engine instruction manual) and pour approx. 3 cm³ of engine oil into the engine via the spark plug hole. Turn the engine several times with the spark plug removed (pull the recoil starter rope).

Fire hazard!

Keep the spark plug socket away from the spark plug hole due to the danger of ignition.

• Screw the spark plug back in (see engine instruction manual).
• Perform an oil change (see engine instruction manual).
• Store the machine in a dry and locked place that is generally free of dust. Make sure that it is out of the reach of children.

13. Transport

13.1 Transporting

Risk of injury!

Observe the section "For your safety" before transporting. ( 4.4) Carry the machine only with the help of a second person. Always wear suitable safety clothing (safety shoes, thick gloves). Detach the spark plug socket before lifting or transporting.

Lifting or carrying the machine

• ⒶHandlebar installed: Hold the machine at the front carrying handle (1) and at the handlebar (2).
• BHandlebar folded down: Hold the machine at the front carrying handle (1) and at the lower handlebars (3).

Transporting the machine

Only transport the machine on all four wheels, on a clean, level load floor.

• Secure the machine against slipping using suitable fastening materials. Fasten ropes or straps at the front carrying handle (1) and at the lower handlebars (3).

14. Environmental protection

Lawn clippings should be composted and not disposed of in household waste.

The machine, its packaging and accessories are all produced from recyclable materials and must be disposed of accordingly.

By disposing of materials separately, and in an environmentally friendly manner, valuable resources can be re-used. For this reason, the machine should be disposed of for recycling at the end of its useful life. Pay particular attention to the information in the "Disposal" section during disposal ( 4.9).

Consult your recycling centre or your specialist dealer for information on the proper disposal of waste products.
