• Remember that the machine operator or user is responsible for accidents with other persons or their property.
  • These operating instructions belong to the machine and must be handed over to the new owner in the event of the machine being sold.
• Never allow children and persons under 16 years of age or other persons not familiar with the operating instructions to use the machine. Local regulations can specify the minimum age of the user.
• Explain the potential hazards and how to avoid accidents to all those who are to use the equipment. This equipment may only be used, serviced and repaired by persons who are familiar with it and have been informed about the hazards.
• This equipment is not intended to be used by persons with limited physical, sensory or mental aptitude or lack of experience and/or knowledge unless they are supervised by a person responsible for their safety and have received instructions from this person as to how the equipment is used. This supervisor must decide in advance whether the person with limited physical, sensory or mental aptitude is suitable for this task.

Never use the mower while persons, particularly children, or animals are nearby.

• Keep your machine safely! Unused equipment should be kept in dry, closed rooms inaccessible to children.
• Machine safety and protective devices must not be manipulated or disabled.
• The laying of cables must not be manipulated, e.g. by removing cable clamps or attaching additional cable ties! The cables must lie against the outside of the bar in such a way that they are neither crushed nor overstretched when the bar is folded. A damaged cable may result in a technical defect of the equipment.

Preparatory measures

• When mowing, you must always wear a strong, closed, non-slip pair of shoes or safety shoes and long trousers. Avoid wearing loose clothing or clothing with cords or belts hanging down. Do not mow whilst you are barefooted or wearing sandals. Wear protective goggles to protect your eyes.
• Loud noises can lead to hearing impairments. Wear ear protection.

Before and during mowing, check the whole area the equipment is being used on and remove all stones, sticks, wires, toys and other objects which can be caught and catapulted out.

Before and during the mowing process, check the area for live wires and remove them if possible.

Never move over live wires when the cutting tool is switched on. Risk of electric shock!

If a live wire is damaged, switch off the equipment and disconnect the wire from the supply grid.

- If you also use a mowing robot for lawn care, the following safety instructions must be heeded with regard to the working area of the mowing robot:

– Before mowing on these areas, always check the range of the boundary wire.
- If the wires are laid in the ground they must be checked, no wires may be visible, with particular attention necessary at the charging station.

EN

• If the boundary wires are laid above ground they should be routed tight directly on the ground and not lie loose in the grass. The wires must be sufficiently fixed using boundary staples, see the operating manual.
• The boundary staples must not project, if this is the case push them firmly in place.
• Remove any residual wires before starting to mow.

In the cases described above, there is a risk of the wire being pulled in and wound up by the tool; this can lead to serious injury.

- Low-hanging branches and similar obstacles can injure the operator or interfere with the mowing operation. Before mowing, identify potential obstacles such as low-hanging branches, and trim back or remove those obstacles.

WARNING

• Petrol is highly inflammable and explosive.
• Fire and explosions can cause severe injury and material damage.
• Store petrol only in a suitable container, and out of the reach of children.
• Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling up.
• Only fill the tank in the open and when the engine is cold. No smoking and no naked flames while filling the tank.
• Fuel operated equipment, which is positioned on a load floor or a trailer, must not be refuelled from a filling pump, but must be refuelled by a fuel container.
• The petrol must be filled into the tank before starting the engine.
• Whilst the engine is running or if the machine is hot, the lid of the petrol tank must not be opened, nor may the tank be filled with more petrol.
• If petrol has overflowed, you must not attempt to start the engine. Instead, remove the machine from the area contaminated with petrol, and wipe the overflowed petrol off the engine. Avoid any attempt to start the engine until the petrol fumes have evaporated.
• For safety reasons, the petrol tank and the petrol container must be closed again carefully.

• If any damage has occurred, the petrol tank and the petrol tank lid must be exchanged.

• Before use, always carry out a visual inspection to see whether the cutting tool, attachment screws and the complete cutting unit are worn or damaged. To avoid unbalance, worn or damaged blades and attachment screws must be replaced by an authorised workshop.

• The condition of the pictograms must be checked every time the device is used. Worn or damaged pictograms must be replaced.

Handling

• The machine must not be operated in potentially explosive surroundings.
• The internal combustion engine must never be used in enclosed rooms in which dangerous exhaust fumes can build up - danger of poisoning.
• People with pacemakers must not touch any parts of the engine which might be live.
• Attention! Do not operate the unit in front of the extraction openings of air conditioning systems.
• Do not mow in bad weather when lightning could strike.
• Never remove the spark plug connector when the motor is running. Risk: Electric shock!
• Disconnect the spark plug connector only when the engine has cooled down. Danger of burns!
• Do not wear radio or music headphones. Safe service and operation requires your full attention.
• Only mow during daylight or if the lighting is good. Always push the machine at walking pace.
• Please adjust the driving speed depending on the person and the terrain. Increase speed gradually until you have reached a suitable driving speed, switch the motor drive off if necessary.
• Use care when approaching blind corners, shrubs, trees, or other obstacles that may obscure vision.

• Do not move too closely to holes, trenches and banks. The equipment can suddenly topple over when a wheel suddenly gives way over the edge of a trench or a bank or when an edge suddenly yields.

• Please be careful when mowing underneath playground equipment (e.g. swings). The equipment could get into an unsafe position. This may result in risk of injury.

• Do not operate the equipment when you are sick, tired or under the influence of alcohol, medicine or drugs.
• Avoid using the machine if possible on wet grass, in order to avoid the danger of slipping.
• Always make sure that you are standing securely whilst mowing slopes. Always mow at right angles to the slope, never mow straight up or down. Please be especially careful when you change direction when mowing on a slope.
• Do not mow excessively steep slopes! Mowing slopes always means additional risks. Your lawnmower is powerful enough to mow on slopes with a gradient of up to 46% (25° angle of slope). For safety reasons, however, we urgently recommend you do not exploit this theoretical performance potential. Always make sure you have a firm stance. Manually guided lawnmowers should never be used for slopes with a gradient in excess of 26% (15° angle of slope). Stability may be lost.
• Please be especially careful when turning the machine or pulling it towards yourself.
• If you walk backwards whilst using the machine, you can easily stumble so this should be avoided. Avoid unnatural body positions. Ensure that you are standing securely and keep your balance at all times.
• Always observe the safety distance to the machine which is maintained by the handlebar.
• In order to avoid the machine slipping when being carried, always hold the machine by the grip devices provided (carrying handle, housing, handlebar ends or transverse bar of the lower handlebar section). Do not grasp the machine by the ejection flap!
• Note the weight of the machine before lifting or carrying it (see technical data). Lifting heavy weights can lead to health problems.
• Never lift or carry the machine when the engine is running.
• Never use the machine with safety and protective devices damaged or missing. Missing or damaged safety and protective devices are a safety hazard for both you and other people.

Safety equipment includes (see chapter Component description):

- Motor stop safety control bar (1)

The lawn mower is equipped with a motor stop device. During operation and in the event of a hazard, the engine is switched off by releasing the motor stop bar.

The engine and the blade must come to a standstill within 3 seconds. After release, the bar must always return to the position shown in the "component description" diagram.

If this is not the case, it must be checked immediately by an authorised workshop.

Risk of injury!

If the blade run-on time is longer, stop using the equipment and take it to an authorised workshop.

Measuring run-on time

After the engine has been started, the blade rotates and a wind-like noise can be heard.

The run-on time corresponds to the duration of the wind-like noise after the engine has been stopped, it can be measured using a stopwatch.

The function of the safety control bar must never be put out of operation.

It is important to make sure that the safety control bar functions correctly. If this is not the case, have it repaired by an authorised specialist workshop.

Protective equipment includes (see chapter Component description):

– Housing, splash guard (12)

These protection units protect against injuries through objects that are thrown upwards.

The equipment must not be operated with a damaged housing or without correctly attached splash guard.

- Housing

This protection unit protects against injuries through contact with the rotating cutting blade bar.

The equipment must not be operated with a damaged housing. Please make sure that hands and feet are not placed underneath the housing.

– Belt drive covers (11), engine covers (5)

These protection units protect against injuries through moving parts.

The equipment must not be operated with damaged covers or without correctly attached covers.

– Exhaust protection grill (10)

The engine/exhaust becomes very hot. The protection grill protects the user against burns.

Do not operate the machine without the exhaust protection grill.

The safety devices must not be modified.

• Do not change the basic settings of the engine or operate the engine at excessive speed.
• During the starting process, do not switch on the drive if available.

When you start the machine, make sure that your feet are at a sufficiently safe distance away from the cutting blades.

When the engine is started, the machine must not be tilted on end, if necessary it must be tilted by pressing the guide bar down so that the cutting tool is pointing in the direction away from the user, but only as far as absolutely necessary. For as long as the equipment has not been lowered to the ground again, both your hands must be on the top part of the bar.

Do not start the engine when persons or animals are standing in front of the mower.

When using equipment with a side ejector, do not start the engine when you are standing in front of the ejector channel or other people/animals are located in the ejection area.

Never put your hands or feet near or under revolving parts. Always make sure that your hands or feet do not get under the housing. Always maintain a safe distance from the ejector opening.

Stop the engine by releasing the motor stop bar, disconnect the spark-plug connector, make sure that all moving parts have come to a complete standstill and the ignition key, if there is one, has been removed:

• if you intend to leave the machine;
  – before you inspect, clean or carry out work on the machine;
  – before unblocking jams or removing blockages in the ejection channel;
• if a foreign body has been encountered.

• when the machine starts to vibrate strangely.

• If a foreign object has been encountered or if the machine becomes blocked, e.g. by driving onto an obstacle, a specialist dealer must check whether parts of the machine have been damaged or deformed. Any necessary repairs must also be carried out by an authorized specialist workshop.

• If the machine starts to vibrate unusually heavily or to make unusual noises, please have it checked immediately by an authorised workshop. Heavy vibrations on your hands can damage your health. Please contact an authorised workshop immediately if heavy vibrations occur.

• WARNING

The noise and vibration levels shown in these operating instructions are the maximum levels for use of the machine.

The use of an unbalanced cutting element, the excessive speed of movement, or the absence of maintenance have a significant influence on noise emissions and vibrations. Consequently, it is necessary to take preventive steps to eliminate possible damage due to high levels of noise and stress from vibration.

Maintain the machine well, wear ear protection devices, and take breaks while working.

Adhere to the maintenance work listed in this operating manual and have the equipment checked and serviced regularly by an authorised workshop.

Stop the engine by releasing the motor stop bar, make sure that all moving parts have come to a complete standstill and the ignition key, if there is one, has been removed,

• if you have to lift or tilt the mower e.g. for transport purposes;
• when you need to transport the machine to and from the area to be mowed
• when driving off the lawn;
• if you have to leave the machine for a short time;
• when you wish to adjust the cutting height;
• before you fill it with fuel. Only refill when the engine is cold!

- If the engine is equipped with a petrol shut-off valve, this should be closed after mowing.

Maintenance and storage

- Insufficient equipment maintenance will lead to safety-related faults.

- Ensure that all screws have been tightened securely and that the machine is in a safe working condition.

Never store a machine which still contains petrol inside a building where petrol fumes may come into contact with naked flames or sparks or where they may ignite.

The engine and exhaust reach very high temperatures during operation. Allow the machine to cool down for at least 15 minutes before starting any maintenance or cleaning work.

- To avoid a fire hazard, keep the engine, muffler (exhaust) and fuel tank free of grass, leaves or escaping oil (grease). When tilting the machine upwards or placing it on its side, make sure no oil or petrol escapes. Fire hazard! Allow the engine to cool down before you store the machine in closed rooms. Do not store the machine near open flames or sources of fire such as boilers or heating systems.

Before you start mowing, always check the condition and firm attachment of the cutting blade. The blade attachment screw must always be tightened by an authorised workshop. If the blade screw is too tight or too loose, the blade coupling and cutter bar can become damaged or loose which can lead to serious injuries. A worn or damaged blade must always be replaced.

Changing, regrinding and balancing the cutting blade must be carried out by an authorised professional workshop.

A wrongly assembled cutting blade coupling can allow the cutting blade bar to get loose and cause severe injuries.

An improperly ground and imbalanced cutting blade can cause strong vibrations and damage the lawn mower.

- For reasons of safety, always replace worn or damaged parts.

Protective gloves must be worn at all times during maintenance and cleaning work.

- When handling operating fluids, such as engine oil and fuel, suitable protective equipment (e.g. suitable protective gloves) must be worn. The data sheets of the operating fluids must be observed.

Maintenance and cleaning work may only be carried out on level surfaces with the engine switched off and the spark plug connector disconnected. Regular maintenance is essential for safety and top performance.

• Never remove the spark plug connector when the motor is running! Risk: Electric shock.
• Disconnect the spark plug connector only when the engine has cooled down. Danger of burns!
• Make sure that the spark plug connector is firmly seated! Risk: Electric shock.
• If the tank has to be emptied, this should be done in the open, and with a cold engine. Take care to ensure that no fuel is spilt.

For reasons of warranty and safety, only genuine spare parts may be used. Non-equivalent spare parts can damage the machine and are a safety hazard.

9 BEFORE USING THE LAWNMOWER FOR THE FIRST TIME

Safety instruction!

See table for explanation of symbols page 3

Check all screw connections and the spark plug connector for a tight fit. Tighten the screws if necessary! Attachment of the cutter bar must be checked in particular (refer here to the chapter "Cutter bar care").

The blade attachment screw must always be tightened by an authorised workshop. If the blade screw is too tight or too loose, the blade coupling and cutter bar can become damaged or loose which can lead to serious injuries.

The lawn mower is equipped with a motor stop device.

Before using the equipment for the first time, make sure that the motor stop safety control bar is working perfectly. When the control bar is released, the motor and cutter bar must come to a standstill within three seconds.

After release, the bar must always return to the position shown in the "component description" diagram.

If this is not the case, it must be checked immediately by an authorised workshop.

Risk of injury!

If the blade run-on time is longer, stop using the equipment and take it to an authorised workshop.

Measuring run-on time

After the engine has been started, the blade rotates and a wind-like noise can be heard. The run-on time corresponds to the duration of the wind-like noise after the engine has been stopped, it can be measured using a stopwatch.

Machine safety and protective devices must not be manipulated or disabled!

Make sure that all protective devices have been attached properly and are not damaged.

Filling with oil (Illustration Y1)

Safety instruction!

See table for explanation of symbols page 3

IMPORTANT

Avoid damage! Engine is delivered without oil. You must add oil before running the engine.

Before starting the engine for the first time, use a funnel to fill motor oil (quantity and quality see technical data) having unscrewed the dipstick in this opening first.

Set the mower on level ground.

- Slowly fill oil through the filler neck. Do not overfill. After filling the oil, wait for about one minute and then check the oil level.

Insert the dipstick and screw it tight.

- Check oil level

Remove the dipstick. Use a clean cloth to wipe off the dipstick, then insert it again and screw tightly. Then pull the dipstick out again and read off the oil level. The oil must be at the full mark at the top (arrow). Replenish oil if necessary. The oil level must not be higher than the full mark, however.

Insert the dipstick again and tighten.

- After initial filling, remove the "NO OIL" sign from the top of the engine.

Filling with fuel

Safety instruction!

See table for explanation of symbols page 3

• Only fill the tank with fresh and clean unleaded standard petrol. Fuel with up to 10% ethanol is acceptable.
• Unscrew tank cap.
• Fill tank with fuel using a funnel up to max. lower edge of filling nozzle.
• Replace tank cap and screw tight.

10 STARTING THE ENGINE (ILLUSTRATION D + E)

Only start the engine when standing behind of the mower. Never stand on ejection side! Always place the mower on a level area which is not covered with high grass (if the grass is too high it will block the cutter bar start-up and make starting the mower more difficult). When the engine is started, the machine must not be tilted on end, if necessary it must be tilted by pressing the guide bar down so that the cutting tool is pointing in the direction away from the user, but only as far as absolutely necessary. As long as the mower has not been lowered to the ground again, both your hands must be on the top part of the bar.

CAUTION

Hold the starter cable handle firmly when starting. The handle may otherwise slip out of your hand. Risk of injury!

IMPORTANT

The motor only operates when the safety control bracket is pressed against the upper part of the handlebar. As soon as the safety control bracket is released,

this returns to its original position under spring force, the motor brake is actuated, and the motor and blade come to stop within three seconds.

• Push and hold the safety control bar (A) on the top tube D.
• Slowly pull the starter cable (C) until resistance is felt, then rapidly pull it out E, – the engine begins to run, slowly recoil the cable.

NOTE

This engine has a ReadyStart® system: This system has a temperature-controlled automatic choke. The engine runs with optimum power at maximum speed, which is required for a clean cutting pattern (engine speed = blade speed).

11 SWITCHING OFF THE ENGINE

- Release the safety control bracket.

12 EMERGENCY STOPPING (ILLUSTRATION F)

Release the safety control lever (A) and the drive switch bar (B).

• The mower will stop.
• The blade will stop.
• The engine will stop.

NOTE

Before every mowing job, make sure that the safety control bar for the engine brake and the engine drive control bar are working perfectly:

- when the safety control bar is released, the engine and cutter bar must come to a standstill within three seconds.

- when the engine drive control bar is released, the machine must come to a standstill immediately.

If this is not the case, please consult your nearest authorised workshop.

13 MOVEMENT DRIVE

Operating the rear wheel drive (Illustration G)

The rear wheel drive is switched on and off using the drive switch bar (B) on the upper handle when the engine is running:

• Press drive switch bar and hold = mower runs.
• Release drive switch bar = mower stops (0 position).

NOTE

Click the rear wheels if the mower thrusts forward when the engine is turned off.

Adjusting the speed (Illustration H)

IMPORTANT

The speed may only be adjusted when the engine is running in order to avoid damage!

The operating speed can be continuously adjusted using the operating lever of the variable speed switch.

- First, push the lever (1) downwards to unlatch and then adjust in both directions to set the speed you require (2). The lever automatically clicks back into the nearest new position.

• Position "hare" = fast (max. speed).
• Position "tortoise" = slow (min. speed).

NOTE

Mowing at high speed leads to poor cutting pattern or collection result. Always adapt the speed to the prevailing conditions. For longer grass sections, a slower moving speed should be selected.

14 MOWING

Safety instruction!

See table for explanation of symbols page 3

Mowing on slopes

NOTE

The mower can be used on banks and slopes with a gradient of up to 46% (25° angle). Any steeper slopes can lead to engine damage.

For safety reasons, however, we urgently recommend you do not exploit this

theoretical performance potential. Always make sure you have a firm stance. Manually guided lawnmowers should never be used for slopes with a gradient in excess of 26% (15° angle of slope). Stability may be lost!

Checking the oil level

Check oil level each time prior to mowing Y1. Never let the engine to run with too little or too much oil. Irreparable damages could occur.

Checking operating safety

The lawnmower is equipped with a motor stop device.

Before every mowing job, make sure that the motor stop safety control bar is working perfectly. When the control bar is released, the motor and cutter bar must come to a standstill within three seconds.

After release, the bar must always return to the position shown in the "component description" diagram.

If this is not the case, it must be checked immediately by an authorised workshop.

Risk of injury!

If the blade run-on time is longer, stop using the equipment and take it to an authorised workshop.

Measuring run-on time

After the engine has been started, the blade rotates and a wind-like noise can be heard. The run-on time corresponds to the duration of the wind-like noise after the engine has been stopped, it can be measured using a stopwatch.

Machine safety and protective devices must not be manipulated or disabled.

The perfect function of the motor drive control bar must also be checked before every mowing job. When the motor drive control bar is released, the machine must come to a standstill immediately. If this is not the case, it must be checked immediately by an authorised workshop.

Make sure that all protective devices have been attached properly and are not damaged.

To avoid risk, check the condition and firm attachment of the blade before every mowing job. The blade attachment screw must always be tightened by an authorised workshop. If the blade screw is too tight or too loose, the blade coupling and cutter bar can become damaged or loose which can lead to serious injuries. A worn or damaged blade must always be replaced. (Refer here to the chapter "Cutter blade care").

In addition, check blade coupling every 10 operating hours for wear and a tight fit. Also check equipment screws and nuts for a firm fit and tighten if necessary.

Make sure the spark plug connector is fitted tightly. Danger: Electric shock. Disconnect the spark plug connector only when the engine has cooled down. Danger of burns! If the mower mechanism becomes blocked e.g. by colliding with an obstacle, have an authorised workshop check whether any parts of the mower are damaged or deformed. Always have any necessary repairs done by an authorised workshop too.

If the machine starts to vibrate unusually heavily or to make unusual noises, please have it checked immediately by an authorised workshop.

Time restrictions

In Germany, the set hours for operating lawnmowers are regulated in the "32nd Ordinance implementing the Federal Emissions Protection Act (32nd BlmSch-V)".

In addition, there may be regional restrictions (e.g. to protect midday peace), which can be issued by the respective local authority.

Tips on caring for your lawn

Mowing (Illustration M)

WARNING

Remove any objects (stones, wood, branches, etc.) from the lawn before each cut; but still watch out for objects lying around during the mowing process.

Ask your dealer about lawn care instructions. Information and instructions about mowing can also be found on the manufacturer website.

Mulching

What is understood by the term mulching?

When mulching, the lawn is cut and the cut blades of grass are then, immediately thereafter, chopped several times to become even smaller using the special mulch blade. This mulch blade straightens the grass blades and cuts the blades into very short segments which are then distributed evenly over the lawn surface.

The grass blade segments can now dry and rot more quickly, thus facilitating the production of humus. This enables natural fertilisation of the soil and also protects against dehydration.

Gathering and removal of cuttings is no longer necessary. The mulch concept is thus environmentally-friendly and stimulates the ecology.

How is the perfect grass blade cut achieved?

The length of the grass to be cut should not exceed 10 cm when a mulching mower is used. A maximum of 1/3 of the grass height is cut in one working cycle. If a positive result is not achieved, mulching may have to be repeated.

Depending on the type of lawn and growth intensity, the grass should be mowed regularly. During the strong growing phase in particular, mulch-mowing needs to be done more frequently than traditional mowing with grass collection, since the one-third rule is hard to keep otherwise.

To achieve an optimum mulching result you should reduce the machine speed for mulching compared to traditional mowing to allow the grass to remain in the mowing blade longer and thus be cut several times.

The best cutting pattern and result are achieved on a dry lawn, since wet cut grass will stick together and clump quickly. These grass clumps will rot and mould, preventing the desired ecological cycle.

If the lawn has to be mowed in a very damp, wet state, the cut grass must be shorter i.e. the cutting height must be set 1-2 levels higher than with a dry lawn.

You will notice that if you follow these simple rules you will have a healthy lawn and can save on disposing of your grass cuttings.

15 SERVICE INTERVALS

16 CARE AND SERVICING OF YOUR LAWNMOWER

Regular care is the best way to guarantee a long service life and problem-free operation. Insufficient equipment maintenance will lead to safety-related faults!

Only use original spare parts because only those guarantee safety and quality!

Safety instruction!

See table for explanation of symbols

page 3

Cleaning (Illustration O)

IMPORTANT

Tilt the mower forwards for cleaning and maintenance work O (spark plug facing upwards). If it should become necessary to place the mower on its side, then place it on the exhaust side, never on the carburettor side, as otherwise start-up problems could occur. Secure the mower in its raised position!

NOTE

When tilting the mower upwards or placing it on its side, make sure no oil or petrol escapes. Fire hazard!

Remove dirt and residual grass directly after mowing. Use a brush or cloth for cleaning. Do not rotate the cutter bar, as otherwise motor oil is pumped into the carburettor/air filter and start-up difficulties can occur.

IMPORTANT

Never use high-pressure cleaners or a normal water jet to clean the drive area, engine parts (such as ignition system, carburettor etc.), seals and bearing points. Damage or expensive repairs can be the consequence of such action.

Collapsing the handle (Illustration B4 + C4 + D4)

• Take the starter cable handle out of the bracket.
• Release the handle nut (A) on each side by 25 mm (1 in.). Fold the top part of the bar (B) down carefully B4.
• Remove the handle nut (C) and the flat round screw (D) on both sides C4.
• Lower the bottom handlebar (E) forwards carefully. Lay the throttle cables along the inside of the lower bar. Do not jam, kink nor squeeze the throttle cables in the process D4.
• Attach the flat round screws and handle nuts to the bracket.

CAUTION

When the bar is moved for transport and storage purposes, the bar may fold over unintentionally during loosening of the handle nuts (A) B4 and following removal of the handle nuts (C) and flat round screws (D) C4. In addition, crushing spots can occur between the base and top of the bar and the housing. This may result in risk of injury.

IMPORTANT

Make sure that the cables are not pinched, squeezed, twisted or overstretched when the handlebars are folded apart or collapsed! Always run the cables along the outside of the bar connection. A damaged cable may result in a technical defect of the equipment.

Transporting and securing the equipment

• If the equipment has to be carried, hold it by the steel housing at the front and the wheel case at the back.
  Please take the weight of the machine into consideration before lifting it (see Technical Data). Lifting large weights can result in health problems. We recommend that two people should always lift or carry the equipment.
• Transport the unit upright on all 4 wheels to avoid fuel loss, damage to the equipment and personal injury.
• Park the means of transport on level ground so that the equipment cannot roll away before it is secured.
• Secure the equipment with approved load-securing devices (e.g. tie-down straps with clamping elements) on or inside the vehicle. Tie-down straps are belt bands made of synthetic fibres. Every tie-down strap is marked with a label. The label contains important details for application. The information on this label must be heeded when using the tie-down strap.
• For loaded goods that can roll, we recommend using direct strapping with four lashing straps. Secure the wheels of the equipment in such a way that it does not move during transportation.

NOTE

Do not tighten the belts too firmly. Fixing the equipment too firmly can cause damage.

Maintenance of the blade

A sharp blade guarantees optimum cutting performance. Before you start mowing, always check the condition and firm attachment of the cutting blade. The blade attachment screw must always be tightened by an authorised workshop. If the blade screw is too tight or too loose, the blade coupling and cutter bar can become damaged or loose which can lead to serious injuries. A worn or damaged blade must always be replaced.

Sharpening and balancing the blade

WARNING

The sharpening and balancing of the blade should be carried out only by an authorized specialist workshop. An improperly sharpened or unbalanced blade can cause severe vibrations, and damage the lawnmower.

Replacing the blade

WARNING

The cutting blade bar must always be replaced by an authorised workshop. A wrongly assembled cutting blade coupling or a blade screw that is tightened too tightly or too loosely can allow the cutting blade bar to become loose and cause severe injuries.

• Only use genuine cutter bars for replacement. Non-equivalent spare parts can damage the machine and are a safety hazard.
• Replacement cutting tool must be marked permanently with the name and/or company logo of the manufacturer or supplier and the part number.

Servicing the front wheels

Lubricate the wheel bearings once a year or every 15-20 operating hours.

- Use a socket wrench to loosen the hexagon nut, washer and wheels.

- After the bearings have been lubricated with roller bearing grease "KAJO-Longlife grease LZR 2", push the wheels back in place, replace the washer, fix the hexagon nut and tighten until the wheels can just about turn easily but without play.

Servicing the rear wheel drive (Illustration R)

Lubricate the wheel bearings once a year or every 15-20 operating hours.

• Pull the drive wheels off after loosening the nuts and removing the washer from the wheel axle.
• Remove any soiling and residual grease from the wheel cover, the free-wheeling pinion on the gear shaft and the drive pinion on the inside of the wheel.

NOTE

Do not remove the free wheel pinion from the gear shaft!

• Lubricate the pinion pair (free-wheeling pinion and drive pinion in the wheel) using the roller bearing grease "KAJO-Longlife grease LZR 2" all the way around so that the gaps between the teeth are filled completely.
• When putting the drive wheel in place make sure the pinions interlock, turn the wheel on the axle slightly to achieve this if necessary.
• Set the disc in place, fix using the hexagon nut and tighten to such an extent that the wheels can just about turn easily but without play.

Safety instruction!

See table for explanation of symbols

page 3

WARNING

Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause serious illness or death.

Do not run an engine in an enclosed area, such as a garage, even with doors and windows open.

Move the machine to an outside area before starting the engine.

IMPORTANT

Tilt the engine and/or mower forwards for cleaning and maintenance work O (spark plug facing upwards). If it should become necessary to place the engine/mower on its side, then place it on the exhaust side, never on the carburettor side, as otherwise start-up problems could occur. Secure the mower in its raised position!

ATTENTION

When tilting or placing the mower on its side, ensure that no oil or fuel comes out of the machine. Fire hazard!

The regular implementation of the prescribed maintenance and care work are the prerequisite for a permanent and fault-free functionality of the motor and also the basic requirement for any guarantee claims.

The motor should be kept clean, particularly on the outside, and the silencer and cylinder area must always be kept free from foreign bodies (e.g. grass residue). The exhaust and motor reach very high temperatures when in use. Flammable foreign bodies such as foliage, grass etc. may catch fire.

Perfect cooling can also only ensured when cylinder ribs are always clean.

IMPORTANT

Never use a pressure cleaner or ordinary water jet to clean the motor. Damages or expensive repairs can be the consequence of such action.

Cleaning engine cooling fins

IMPORTANT

Avoid damage! Keep fins clean or engine may overheat.

• Park the mower on level surface and switch off engine.
• Let engine cool.
• Disconnect the spark plug cable.
  – Clean the fins with a brush or rag.

Oil change

Check the oil level before every use and replenish oil if necessary (see "Check oil level" and "Fill with oil", illustration Y1).

An oil change is not necessary. If you wish to change the oil, however, please follow the instructions below.

NOTE

For environmental reasons, we recommend that the oil change is performed by an authorised workshop.

Changing the oil

• Before the engine or the equipment is tilted to drain oil, empty the petrol tank and let the engine to run until it stops due to lack of fuel.
• Stop the engine and remove the spark plug connector.
  – Renew the oil as long as the engine is warm.

• To change the oil, remove the dipstick from the oil refill neck.

• Turn the mower on one side so that the spark plug side is facing upwards and the used oil can drain into a container.
  Do not drain used oil into the sewage system or soil; dispose of it according to the local regulations.

- Position the mower straight and fill brand-name oil into the spout (for quantity and quality, see technical data). Screw the dipstick in and check the oil level (see "Check oil level" and "Fill with oil", illustration Y1)! If the oil level is correct, insert the dipstick and tighten it.

Filling fuel tank

IMPORTANT

Avoid damage! Dirt and water in fuel can cause engine damage.

Clean dirt and debris from the fuel tank opening.

Use clean, fresh unleaded fuel.

Fill the fuel tank at the end of each day's operation to keep condensation out of the fuel tank.

• Switch off engine. If engine is hot let it cool several minutes before you add fuel.
• Remove grass clippings and other dirt from tank area.
• Remove fuel cap.
• Fill tank with fresh fuel only to bottom of filler pipe.
• Reinsert fuel cap.

Cleaning and replacing the air filter (Illustration W)

IMPORTANT

Never let the engine start or run whilst the air filter is removed.

• Loosen the nut (1) on the air filter cover (2) and remove the cover.
• Remove the pre-filter (3) and paper filter element (4).
  – Clean the paper filter element every 50 operating hours.
  Knock gently onto a smooth surface if soiled lightly. Replace if heavily soiled or damaged. Do not wash out paper filters, nor blow them out with compressed air or grease them.
  – Clean the pre-filter every 50 operating hours.
  Wash pre-filters in hot water with liquid detergent, rinse them out in clean water, press out excess water and allow to dry thoroughly in air. Do not lubricate the pre-filter with oil.
• Insert the dry pre-filter on the paper filter element and fit both in the air filter plate (5). Ensure that the air filter sits firmly in the plate.
• Put the cover (2) on the air filter and fasten it with the nut (1) on the air filter plate (5).

In the case of unfavourable operation conditions (severe formation of dust), cleaning is required after every mowing process. Replace the paper filter element and pre-filter annually or every 200 operation hours.

(Please see original spare parts and accessories for Order No. of filter element and prefilter)

Checking the spark plug (Illustration Y)

To check for wear, remove the spark plug connector and unscrew the spark plug. If the electrode is badly worn the spark plug must be replaced as a matter of course. (Order no. see original spare parts list and accessories).

Otherwise it is sufficient to clean the spark plug and set the electrode gap to 0.5 mm.

Screw the spark plug (pay attention to sealing ring) into the engine by hand and tighten using the socket wrench. Press on spark plug connector. Replace the spark plug annually.

Correct winter storage of the engine (or when not used for a long period of time)

– Empty the petrol tank or allow the engine to run until it stops due to lack of fuel.
- Switch off engine and disconnect spark plug cable.
- Drain off the oil while the engine is still warm. Fill with fresh oil (for quantity and type, see technical data).
– Clean grass and chaff from cylinder and cylinder head fins and around muffler.
- Always keep the machine in a clean condition in a closed, dry room out of reach of children.
