Preliminary measures

1. Always wear sturdy, non-slip footwear and long trousers when mowing. Never mow barefoot or in sandals.
2. Check the grounds on which the machine will be used and remove all objects that could be caught up and violently flung out of the chute.

3. Warning: Petrol is highly flammable! Therefore: - Only store petrol in containers designed to hold petroleum-based liquids.

4. Only refuel out in the open and do not smoke during the refueling process.

5. Always refuel the lawn mower before starting the engine. Always ensure that the fuel tank cap is closed when the engine is running and when the mower is hot; also do not refuel.
6. If petrol has overflowed, do not under any circumstances attempt to start the engine. Instead, remove the machine from the affected area. Avoid starting the engine until the petrol fumes have completely evaporated.

7. For safety reasons, the petrol tank and other tank closures must be replaced if they are damaged.

8. Replace defective mufflers.

9. Before using the mower, visually inspect it to ensure that the blade, mounting bolts and the entire cutting apparatus are in good working order (i.e. not worn out or damaged). To prevent any imbalance, replace worn out or damaged blades and mounting bolts as a set only (if applicable).

1. Handling

1. Do not let the combustion engine run in enclosed areas, as dangerous carbon monoxide gas can

build up.

1. Only mow in broad daylight or in well-lit conditions. Avoid using the machine on wet grass as far as possible.
2. Always maintain good footing on inclines.
3. Only operate the machine at a walking pace.
4. For machines with wheels: Always mow across hills i.e. never straight up or straight down.
5. Be particularly careful when you change direction on a slope.
6. Do not mow on overly steep inclines.
7. Always be extra careful when turning the mower around and when pulling it towards you.
8. Switch off the lawn mower and ensure that the blade has stopped rotating whenever the mower has to be tilted for transporting over areas other than lawns and whenever it has to be moved from or to the area you want to mow.
9. Never use the lawn mower if the blade or safety grilles are damaged, or without the attached guards, e.g. deflectors and/or grass catching devices.
10. Do not adjust or overclock the engine speed settings.
11. Release the engine brake before you start the engine.
12. Start the engine with care, in accordance with the manufacturer's instructions. Make sure that your feet are far enough away from the mower blade!
13. Do not tilt the lawn mower when you start the engine unless the mower must raised off of the ground a little in order to start it. In the latter case, tilt the mower as little as absolutely necessary and only raise the side opposite to that of the user.
14. Never start the engine while standing in front of the chute.
15. Never move your hands or feet toward or under any rotating parts. Keep clear of the chute opening at all times.
16. Never lift or carry a lawn mower with the engine running.

3. Proper operation

The petrol lawn mower is intended for private use i.e. for use in home and gardening environments.

Private use of the lawn mower refers an annual operating time generally not exceeding that of 50 hours, during which time the machine is primarily used to maintain small-scale, residential lawns and home/hobby gardens. Public facilities, sporting halls, and agricultural/forestry applications are excluded.

The operating instructions as supplied by the manufacturer must be kept and referred to in order to ensure that the lawn mower is properly used and maintained. The instructions contain valuable information on operating, maintenance and servicing conditions.

Important! Due to the high risk of bodily injury to the user, the lawn mower may not be used to trim bushes, hedges or shrubs, to cut scaling vegetation, planted roofs, or balcony-grown grass, to clean (suck up) dirt and debris off walkways, or to chop up tree or hedge clippings. Moreover, the lawn mower may not be used as a power cultivator to level out high areas such as molehills.

For safety reasons, the lawn mower may not be used as a drive unit for other work tools or toolkits of any kind.

4. Assembling the components

Some parts of the lawn mower come disassembled. For quick and easy assembly, read and follow the instructions below.

Important! For assembly and maintenance work you will require the following additional tools not included in the scope of delivery:

● An open-ended wrench, size 10.
● A ring wrench, size 10.
● An open-ended wrench, size 13.
● A flat oil pan (for changing the oil)
● A 1 liter measuring jug (resistant to oil / petrol).
● A petrol canister (5 liters are sufficient for approx. 6 operating hours).
● A funnel (which fits the petrol refueling socket on the tank).
● Household cloths (for wiping residual oil / petrol; dispose of at a petrol station).
● Cutter.
● Pack of adhesive tape.
● A petrol suction pump (plastic version, available from DIY shops).
● An oil can with hand pump (available from DIY shops).
● 1 liter of engine oil, 15W-40.

Assembling the lawn mower

Take the lawn mower and attachments out of the packaging and check that all parts are there (Fig. B). Fasten the lower push bar (Fig. B/5) to the mounts on the mower housing as follows. When doing so, make sure that the tension cables, which are to be fastened later, are not in the way. Remove the two locking cotter pins from the chute flap shaft (Fig. A/8). Slacken the two hand locking screws on the engine housing. Pull the lower push bar apart. Fit it onto the shaft so that it locks into the holders on the engine housing, and the hand locking screw with the start tension cable guide (Fig. A/6, at the top of the push bar) is attached on the right in the pushing direction. Fit the two locking cotter pins again. If the hole is not easy to get to, start at the other side. Then press sideways on the side that has been locked in order to move the shaft a little. Then screw the lower push bar tightly in position with the hand locking screws. Now screw the upper push bar (Fig. B/2) to the lower push bar. Make sure that the start tension cable guide on the right-hand side faces inwards (Fig. C). Then draw both tension cables underneath the crossbar of the lower push bar (see Fig. F). Fasten the tension cables for the engine control and engine brake (Fig. D) in such a way that the lever for the engine control faces outwards and the tension cable holder for the engine brake faces inwards. Fasten the screw and the nut tightly (wrench size 10). Then lift the lever for the engine brake out of the fastening hole on the left-hand side and pull it slightly forwards with your left hand (Fig. E). Then insert the tension cable for the engine brake in such a way that it is inserted in the lever from the outside (Fig. E/1). Secure the tension cables with a cable binder (Fig. F) and cut off the excess length with a cutter.

Checking the setting of the engine brake

Fasten the lever for the engine brake on the upper push bar (Fig. G) with adhesive tape. You should be able to pull the lever for the engine brake smoothly as far as the handle. If this is not the case (the distance between the lever for the engine brake and the upper push bar is greater than approx. 5mm), check whether setting of the engine brake is correct (12. Care and maintenance, Item 5). Remove the adhesive tape when you have finished checking the setting and have adjusted it if required.

Assembly of the grass basket

Place the frame for the grass basket on the ground with the handle in the middle facing upwards (Fig. H). Then place the basket behind the frame with the

hard plastic base facing downwards. Draw the grass basket over the frame such that the top side of the basket stretches over the back part of the frame and the hard plastic base hangs down. Then clamp the grass basket with the plastic bars on the frame. Lift the chute flap with one hand and attach the assembled grass basket over the chute flap shaft (Fig. I)

5. Setting the cutting height

Important! Adjust the cutting height only when the engine is switched off and the plug boot has been pulled.

Before you begin to mow, check to ensure that the blade is not blunt and that none of the fasteners are damaged. To prevent any imbalance, replace blunt and/or damaged blades as a set only (if applicable). To carry out this check, first switch off the engine and pull the spark plug boot.

The cutting height is centrally adjusted with the cutting height adjustor lever (Fig. B 9). Up to 5 different cutting heights can be selected.

Pull the adjustor lever out and select the desired cutting height. The lever snaps into the desired position.

6. Starting up

Important!

The engine does not come with oil in it. Therefore, ensure that you add 0.4 liters of oil before starting it up. Use normal, multigrade oil (15W 40). The oil level in the engine must be checked each time before mowing. (see Checking the oil level).

• In order to avoid any undesired start-ups of the lawn mower, this model is equipped with an engine brake (Fig. J item 1+2) that must be pulled back before the engine can be started. When the engine brake is released it must return to the starting position and the engine will stop automatically.
• Before you start the lawn mower, open the petrol stopcock (Fig. K, arrow = Petrol stopcock open). Move the speed lever (Fig. L) to the choke position. Pull the engine brake lever together (Fig. J item 2) and give the start tension cable a strong pull. You can control the rotation speed of the blade using the speed lever (Fig. L).

GB

● Before you start mowing, you should run through this operation several times in order to ensure that the machine is working properly.
● Whenever you need to perform any kind of adjustment and/or repair work on your lawn mower, wait until the blade has come to a complete stop.

Always switch off the engine before carrying out any adjustments, maintenance or repairs.

Starting up

Note:

1. Engine brake (Fig. J): Use the lever to stop the engine. When you release the lever the engine and the blade stop automatically (Fig. J/1). To mow, hold the lever in the working position (Fig. J/2). Before you start to mow, check the start/stop lever several times to be sure that it is working properly. Ensure that the tension cable can be smoothly operated (i.e. is not catching or kinking in any way).
2. Speed lever (Fig. L): Move this lever in order to increase or decrease the engine speed. (Snail symbol = slow / Hare symbol = fast)
3. Caution: The blade begins to rotate as soon as the engine is started.

Important:

Before you start the engine, move the motor brake several times to be sure that the stop cable is properly working. Note: The engine is factory set to a speed that is optimal for cutting and blowing grass into the basket and is desired to provide many years of use.
designed to provide 4. Check the oil level.
5. Fill the tank with approx. 1.6 liters of petrol whenever empty, using a funnel and measuring jug to do so. Ensure that the petrol is free of any contaminants.

Note: Use only unleaded petrol as fuel.

Warning: Never use more than one safety petrol can. Do not smoke when refueling. Switch off the engine before refueling and allow the engine to cool down for a few minutes.

1. Ensure that the ignition cable is connected to the spark plug.
2. Lock the speed lever in the CHOKE position.
3. Stand behind the mower. Place one hand on the engine start/stop lever. Place the other hand on the starter handle.
4. Quickly pull back the starter handle and let it

slowly return.

1. If the engine does not start up after 5 - 6 pulls. Note: In cold weather, it may be necessary to repeat the starting process several times.
2. If the engine is at normal running temperature it can be started in the slow position (Fig. L). Important: When you attempt to start the engine in the choke position (Fig. L), the engine spark plug can become saturated. Allow a few minutes before attempting to start the engine again.

7. Before mowing

Important information

1. Make sure that you are properly dressed when mowing. Wear sturdy, non-slip footwear; do not wear sandals or tennis shoes.
2. Inspect the blade. A blade that is bent or damaged in any other way must be immediately exchanged for a genuine Einhell replacement blade (special accessory art. no. 34.055.23).
3. Do not fill the fuel tank indoors, but rather out in the open. Use a filling funnel and a measuring jug (an empty tank can be refilled with approx. ca. 1.6 liters of petrol). Wipe off any spilled petrol.
4. Read and follow in the instructions in the operating manual as well as the information regarding the engine and accessory equipment. Store the manual in a place where it can be readily accessed by other users of the machine.
5. Exhaust gas is dangerous. Only start the engine out in the open.
6. Make sure that all the guards are fitted and that they are in good working order.
7. The machine should only be operated by persons who are well informed with the way it works, and who are in reasonably good physical condition.
8. It can be dangerous to mow the grass when it is wet. Try to ensure that you only mow the grass when it is dry.
9. Advise children and others to keep well away from the lawn mower.
10. Never mow the grass in poor visibility.
11. Remove all loose objects from the lawn before you start mowing the grass.

8. Tips for proper mowing

Important! Never open the chute flap when the catch bag has been detached (to be emptied) and the engine is still running. The rotating blade can cause serious injuries!

Always carefully fasten the chute flap and grass basket. Switch off the engine before emptying the grass basket.

Always ensure that a safe distance (provided by the length of the long handles) is maintained between the user and the mower housing. Be especially careful when mowing and changing direction on slopes and inclines. Maintain a solid footing and wear sturdy, non-slip footwear and long trousers. Always mow along the incline (not up and down). For safety reasons, the lawn mower may not be used to mow inclines whose gradient exceeds 15 degrees. Use special caution when backing up and pulling the lawn mower. Tripping hazard!

9. Mowing

Only use a sharp blade that is in good condition. This will prevent the grass blades from fraying and the lawn from turning yellow.

Try to mow in straight lines for a nice, clean look. Insodoing, the mowing swaths should always overlap each other by a few centimeters in order to avoid bare strips.

Keep the underside of the mower housing clean and remove grass build-up. Deposits not only make it more difficult to start the mower; they decrease the quality of the cut and make it harder for the machine to bag the grass. Always mow along inclines (not up and down). Slightly turning the front wheels up the hill while mowing will prevent the mower from sliding out of the straight line. Select the cutting height according to the length of the grass. If the lawn has grown quite a bit, mow over it several times so that no more than 4cm of grass are cut at one time.

Switch off the engine before doing any checks on the blade. Keep in mind that the blade continues to rotate for a few seconds after the engine has been switched off. Never attempt to manually stop the blade.

Regularly check to see if the blade is securely attached, is in good condition and is sharp. If the contrary is the case, sharpen the blade or replace it. In the event that the blade strikes an object, immediately switch off the lawn mower and wait for the blade to come to a complete stop. Then Inspect the condition of the blade and the blade mount. Replace any parts that are damaged.

Tips for proper mowing:

1. Pay attention to ensure that you do not run into or over anything that could damage the mower.

The lawn mower could be damaged and/or the machine could inflict bodily injury.

1. A hot engine, exhaust or drive unit can burn the skin if touched. Thus, do not touch these parts unless the mower has been switched off for a while and you know that they have cooled down!
2. Use extra caution when mowing on inclines and steep grades.
3. Insufficient daylight or even a sufficient level of artificial light is one reason not to mow.
4. Check the mower, the blade and other parts if they have struck a foreign object or if the machine vibrates more than usual.
5. Do not make any adjustments or repairs until the engine has been switched off. Pull the plug boot.
6. Pay special attention if you are mowing directly next to a street or are close by one (traffic). Always keep the grass chute pointed away from the street.
7. Avoid mowing in places where the wheels have trouble gripping or mowing is unsafe in any other way. Before you back up, ensure that nobody is standing behind you (especially little children, who are more difficult to see).
8. When mowing over thick, high grass, select the highest cutting level and mow at a slower speed. Before you remove any grass or blockages of any kind, switch off the engine and pull the plug boot.
9. Never remove any safety-related parts.
10. Never fill the engine with petrol when it is hot or is running.

10. Emptying the grass basket

As soon as grass clippings start to trail the lawn mower, it is time to empty the grass basket.

Important! Before taking off the grass basket, switch off the engine and wait until the blade has come to a stop.

To take off the grass basket, use one hand to lift up the chule flap and the other to grab onto the basket handle. Remove the basket.

For safety reasons, the chute flap automatically falls down after removing the grass basket and closes off the rear chute opening. If any grass remains in the opening, it will be easier to restart the engine if you pull the mower back approx. 1 meter.

Do not use your hands or feet to remove clippings in or on the mower housing, but instead use suitable tools such as a brush or a hand broom.

GB

In order to ensure that the majority of grass clippings are picked up, the inside of both the catch bag and especially the air grill must be cleaned after each use.

Reattach the catch bag only when the engine is switched off and the blade is stopped.

Using one hand, lift up the chute flap, while grabbing onto the basket handle with the other. Hang in the basket from the top.

11. After mowing

1. Allow the engine to cool before you put the lawn mower in an enclosed area.
2. Remove grass, foliage, grease and oil before storing the mower. Do not place any objects on top of the mower.
3. Check all the screws and nuts once more before you start to use the lawn mower again. Tighten any loose screws.
4. Also be sure to empty the grass basket.
5. Pull the spark plug boot to prevent unauthorized use.
6. Ensure that you do not park the mower next to any source of danger. Petrol fumes can lead to explosions.
7. Only original parts or parts approved by the manufacturer may be used for repairs (see address on the warranty certificate).
8. If the lawn mower is not going to be used for an extended period, empty the petrol tank using a petrol suction pump.
9. Tell your children not to use the mower. It is not a toy.
10. Never place petrol near an ignition source. Always use a can that is approved to store petrol. Keep petrol away from children.
11. Oil and maintain the machine.
12. How to switch off the engine: All you have to do to switch off the engine is release the engine start/stop lever (Fig. J/1). Pull the ignition cable from the spark plug boot in order to prevent the engine from restarting. Before starting up again, check the tension cable for the engine brake. Check that the tension cable is correctly fitted. If the cable is kinked or damaged, it should be replaced.

12. Care and maintenance

Important:

Never work on or touch conducting parts on the ignition unit with the engine running. Always pull the

spark plug boot from the spark plug before starting any work of care or maintenance. Never perform any work on the machine while it is running. Any work not described in these Operating Instructions must be performed by an authorized service workshop only.

1. Cleaning the lawn mower

The lawn mower should be thoroughly cleaned after every use, especially the underneath and the blade mount. To do so, tip the lawn mower onto its left side (the opposite side to the oil filling socket).

Important: Before you tip the lawn mower onto its side, completely empty the fuel tank using a petrol suction pump. The lawn mower must never be tilted by more than 90 degrees. Dirt and grass is easiest to remove immediately after you have finished mowing the grass. Dried on grass and dirt can result in poorer mowing performance. Check that the grass chute is free of any residual grass. Remove any such residue. Never clean the lawn mower with a water jet or high-pressure cleaner. The engine must remain dry. Do not use aggressive cleaning agents such as cold cleaner or petroleum ether.

2. Wheel axles and wheel hubs

These should be lightly greased once a season. To do so, remove the wheel caps with a screwdriver and slacken the fastening screws on the wheels.

3. Blade

For safety reasons you should only ever have your blade sharpened, balanced and mounted by an authorized service workshop. For optimum results it is recommended that the blade should be inspected once a year.

Changing the blade

Only ever use original spare parts when having the blade replaced. The marking on the blade must be matched with the number given in the list of spare parts. Never have any other model of blade fitted.

Damaged blades

Should the blade, in spite of all precautions, come into contact with an obstruction, shut down the engine immediately and pull the spark plug boot. Tip the lawn mower onto its side and check the blade for damage. Damaged or bent blades must be replaced. Never attempt to bend a bent blade back to straight again. Never mow the lawn with a bent or heavily worn blade as this will cause vibrations and can lead to further damage to the lawn mower.

Important: There is a risk of injury if you work with a

damaged blade.

Resharpening the blade

The blades can be resharpened with a metal file. In order to avoid imbalance, the blade should be resharpened by an authorized service workshop.

4. Checking the oil level

Important: Never run the engine with no or too little oil. This could cause severe damage to the engine. Use only 15W40 engine oil.

Checking the oil level:

Stand the lawn mower on a flat level surface. Unscrew the oil dip stick by turning anticlockwise, pull out and wipe. Insert the dip stick back in the filling mount as far as the stop, but do not screw back in. Pull out the dip stick again and read off the oil level while holding horizontally. The oil level must be between the maximum (top edge of the flat-pressed metal stick, Fig. N) and the minimum (bottom edge of the flat-pressed metal stick, Fig. N). The moveable orange plastic part on the oil dip stick provides protection against oil foam.

Changing the oil:

Stand your lawn mower on a work bench with the front right-hand wheel (in the pushing direction) projecting beyond the edge of the work bench. Place a flat oil pan beneath the lawn mower (Fig. O). Remove the oil outlet screw on the underside of the lawn mower (see Fig. P). Completely empty the used oil. Screw the oil outlet screw back on tightly. Fill with 0.4 liters of fresh 15W40 engine oil (see Checking the oil level).

5. Care of the tension cables and setting the

tension cable for the engine brake Oil the tension cables regularly and check that they move smoothly.

● The setting of the engine brake play must be checked every time before starting the mower:
● a) Fasten the lever for the engine brake with adhesive tape (Fig. G).

- b) Check the setting of the play between the setting screw and the tension cable nipple (distance approx. 2 - 4mm, Fig. Q+R).

- c) If the distance is too small (Fig. Q) it must be corrected by slackening the setting screw and readjusting (Fig. R).

6. Maintenance of the air filter

A soiled air filter will reduce the performance of the engine because it will prevent enough air getting to

the carburetor. It is therefore imperative that regular checks are made. The air filter should be checked every 25 hours and cleaned if required. If the air is very dusty the air filter should be checked more regularly.

Important: Never clean the air filter with petrol or inflammable cleaning agents (Fig. S). Clean the air filter with compressed air or simply by knocking out any soiling.

7. Repairs

After any repair or maintenance work, check that all safety-related parts are in place and in proper working order.

All parts which may cause injury must be kept where they are inaccessible to children or others. Important: In accordance with product liability legislation we are not liable for any damages caused by improper repairs or the use of spare parts that are not original spare parts or parts approved by us. In addition, we are also not liable for any damages arising from improper repairs. Such work should be performed by a customer services workshop or authorized specialist. The same applies to accessory parts.

8. Times of use

Lawn mowers are only permitted to be used on workdays between the hours of 7.00 a.m. and 7.00 p.m. Please comply with statutory regulations, which may vary from location to location.

13. Preparing the mower for long-term storage

Caution: Do not empty the petrol tank in enclosed areas, near fire or when smoking. Petrol fumes can cause explosions and fire.

1. Empty the petrol tank with a petrol suction pump.

2. Start the engine and let it run until any remaining petrol has been used up.

3. Change the oil at the end of every season. To do so, remove the used engine oil from a warm engine and refill with fresh oil (see Changing the oil, item 12/4).

4. Remove the spark plug from the cylinder head. Fill the cylinder with approx. 20 ml of oil from an oil can. Slowly pull back the starter handle, which will bathe the cylinder wall with oil. Screw the spark plug back in.

5. Clean the cooling fins of the cylinder and the housing.

6. Be sure to clean the entire machine to protect the paint.

GB

1. Store the machine in a well-ventilated place.

14. Preparing the mower for transportation

1. Empty the petrol tank (see item 13/1).
2. Always let the engine run until it has used up the remainder of petrol in the tank.
3. Empty the engine oil from the warm engine.
4. Remove the spark plug boot from the spark plug.
5. Clean the cooling fins of the cylinder and the housing.
6. Remove the start tension cable from the hook (Fig. A/6). Slacken the wing nuts and fold down the upper push bar (Fig. T).
