Mowing with grass box: Lift the discharge flap (15) with one hand and hang the grass box (16) as shown in Fig. 9.
Mulching:
If the grass box (16) is attached, remove it and replace it with the mulch insert (19) as shown in Fig. 10-12.

Setting the cutting height

CAUTION!
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.13/ Item 14). 7 different cutting heights can be selected.
Pull the adjustor lever out and select the desired cutting height. The lever snaps into the desired position. (Fig. 13)

Preparing the area to be mowed
Before mowing, carefully examine the area. Remove stones, sticks, bones, wires, toys and other objects that may be ejected.

Operation

CAUTION! The engine does not come with oil in it. Therefore, ensure that you add 0,4 litres of oil before starting it up. Use normal, multigrid oil (SAE30). The oil level in the engine must be checked each time before mowing.
You will also need to fill in petrol, as this is also not supplied upon delivery.

In order to avoid any unintentional start-ups of the lawn mower, it comes equipped with an engine brake (Fig. 1/ Item 3) which must be pulled back before the engine can be started. When the engine control lever is released it must return to its initial position, at which point the engine automatically switches off.
Press the engine brake lever (3) together and give the starter cord (17) a vigorous pull. (Fig. 14) Attention: When you pull the starting rope the cutting blade rotates even when dissolved motor brake lever. Make sure that there are no body parts in danger zone of cutting blade.
When the engine is running, press the drive lever (2) to the handle (1) in order to engage drive on the mower.
Before you start mowing, you should run through this operation several times in order to ensure that the machine is working properly.

WARNING
Whenever you need to perform any kind of ad- dustmen 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.
Note!
Using the drive:

Engine brake (3):
Use the lever to stop the engine. When you release the lever the engine and the blade stop automatically.
To mow, hold the drive lever (2) in the working position. 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).
Drive lever (2):
If you press this the clutch for the drive will be closed and the lawnmower will start to move with the motor running. Release the drive lever in good time to stop the moving lawnmower. Practice starting and stopping before you use the mower for the first time until you are familiar with controlling the mower.

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 designed to provide many years of use.

Check the oil level.
Open the fuel tank cap and fill the petrol tank (6) up to the lower point of the tank inlet with about 1,0 litres of petrol. Use a funnel and a measuring con-trainer for filling. Do not overfill the tank. Use fresh, clean unleaded fuel. Never mix oil with petrol. Buy fuel in amounts which can be used within 30 days in order to guarantee its freshness. Note: Use only unleaded gasoline.

WARNING
Only use a safety petrol can. Do not smoke when fueling. Remove any oil or petrol residues. Switch off the engine before refuelling and allow the engine to cool down for a few minutes.
Start engine (Fig. 14)

Ensure that the ignition cable is connected to the spark plug.
Stand behind the mower. One hand squeezes the engine brake lever (3) to the handle, the other pulls the pull start.
Start the engine using the reversing starter (17). To do this pull the handle approx. 10 – 15 cm (until you feel a resistance) and then start the engine with a sharp pull. If the engine does not start, pull the handle again.
Due to protective coating on the engine, a small amount of smoke may be present during the initial use of the product and should be considered normal.

Note: Easier starting in colder temperatures by pressing the primer Fig. 14. Use only by a cold engine!
CAUTION!

Never allow the starter cord to snap back.
Note: In cold weather, it may be necessary to repeat the starting process several times.

Before mowing
Important information

Make sure that you are properly dressed when mowing. Wear sturdy, non-slip footwear; do not wear sandals or tennis shoes.
Inspect the blade. A blade that is bent or damaged in any other way must be immediately exchanged for a genuine replacement blade.
Do not fill the fuel tank indoors, but rather out in the open. Use a filling funnel and a measuring jug. Wipe off any spilled petrol.
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.
Exhaust gas is dangerous. Only start the engine out in the open.
Make sure that all the guards are fitted and that they are in good working order.
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.
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.
Advise children and others to keep well away from the lawn mower.
Never mow the grass in poor visibility.
Remove all loose objects from the lawn before you start mowing the grass.(Like stones, toys, sticks and wires etc.)

Tips for proper mowing
**CAUTION! 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!
Mulching
In the mulching mode the cuttings are shredded in the enclosed mower housing and then spread back onto the lawn. It is not necessary to gather and dispose of the grass.
Note! Mulching is only possible if the lawn is relatively short.
To use the mulching function, disconnect the debris bag (16), slide the mulching adaptor (Fig. 10-12 / 19) into the ejector opening and close the ejector opening (15).
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. Ins doing, 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 4 cm 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:**

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.
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!
Use extra caution when mowing on inclines and steep grades.
Insufficient daylight or even a sufficient level of artificial light is one reason not to mow.
Check the mower, the blade and other parts if they have struck a foreign object or if the machine vibrates more than usual.
Do not make any adjustments or repairs until the engine has been switched off. Pull the plug boot.
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.
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).
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.
Never remove any safety-related parts.
Never fill the engine with petrol when it is hot or is running.

Emptying the grass basket
As soon as grass clippings start to trail the lawn mower, it is time to empty the grass basket.
WARNING
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 (16), use one hand to lift up the chute flap (15) and the other to grab onto the basket handle (Fig. 16). Remove the basket. For safety reasons, the chute flap (15) 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.
In order to ensure that the majority of grass clippings are picked up, the inside of both the grass basket (16) and especially the air grill must be cleaned after each use. Reattach the grass basket (16) only when the engine is switched off and the blade is stopped. Using one hand, lift up the chute flap (15), while grabbing onto the basket handle with the other. Hang in the basket from the top. Fig. 9
After mowing

Allow the engine to cool before you put the lawn mower in an enclosed area. Remove grass, foliage, grease and oil before storing the mower. Do not place any objects on top of the mower.
Check all the screws and nuts once more before you start to use the lawn mower again. Tighten any loose screws.
Also be sure to empty the grass basket (16).
Pull the spark plug boot to prevent unauthorized use.
Ensure that you do not park the mower next to any source of danger. Petrol fumes can lead to explosions.
Only original parts or parts approved by the manufacturer may be used for repairs (see address on the warranty certificate).
If the lawn mower is not going to be used for an extended period, empty the petrol tank using a petrol suction pump.
Oil and maintain the machine.

Cleaning

The lawn mower should be thoroughly cleaned after every use, especially the underneath and the blade mount. To remove the gras, tip the lawn mower onto its left side (the opposite side to the oil filling socket) or clean the mower with water as descript below:

Remove the mulch unit / grass box.
Fit the hose connection to the mower and turn the tap on. (Fig. 23)
Start the mower and switch off again after about 30 seconds. The rotating blade bar throws the water onto the bottom of the mower and thus cleans it.
Turn off the tap and remove the hose connection .
Clean the top with a cloth (do not use any sharp objects).

Note! 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.

Transport

Preparing the mower for transportation (Fig. 22)

Empty the petrol tank.
Always let the engine run until it has used up the remainder of petrol in the tank.
Empty the engine oil from the warm engine.
Remove the spark plug boot from the spark plug.
Clean the cooling fins of the cylinder and the housing.
Remove the start tension cable (17) from the hook. Loosen the quick-release lever (5) and fold the upper push bar down. Make sure the cables are not bent during this process.
Wedge a few layers of corrugated cardboard between the upper and lower push bars and the engine in order to prevent any chafing.

Storage

Never store the mower (with petrol in the tank) inside a building in which petrol fumes could come into contact with open flames or sparks.
Allow the motor to cool before you put the lawn mower in an enclosed area.
In order to avoid fire hazards, keep the engine, exhaust and the area around the fuel tank free from grass, leaves and leaking grease (oil).

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.

Empty the petrol tank with a petrol suction pump.
Start the engine and let it run until any remaining petrol has been used up.
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.
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.
Clean the cooling fins of the cylinder and the housing.
Be sure to clean the entire machine to protect the paint.
Store the machine in a well-ventilated place.

Maintenance

Regular, careful maintenance is required to guarantee the safety level and performance of the machine.
Make sure that all nuts, bolts and screws are tightened securely and that the machine is in safe working condition.
Routinely check the grass basket for signs of wear and impaired functionality. Regularly clean the grass box with water and let it dry thoroughly.
For your own safety, replace worn or damaged parts without delay.
If the fuel tank should require emptying this should only be done in the open air using a petrol suction pump (available from DIY shops).

WARNING 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.
Wheel axles and wheel hubs

These should be lightly greased once a season.

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 (Fig. 17)
Only ever use original spare parts when having the blade replaced.
Wear gloves when replacing the blade in order to pre-vent injury.
Never have any other blade fitted.

Empty the fuel tank before removing the blade
To replace the blade, undo the screw.
Reinstall as illustrated in Fig. 17. Tighten the screw properly. Tightening torque 45 Nm. When replacing the blade, the blade screw should also be replaced.

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.
CAUTION! There is a risk of injury if you work with a damaged blade.
Rehappening the blade
The blades can be rehappened with a metal file. In order to avoid imbalance, the blade should be rehappened by an authorized service workshop
Checking the oil level
CAUTION! Never run the engine with no or too little oil. This could cause severe damage to the engine. Use only SAE30 engine oil.
Checking the oil level (Fig. 18):

Stand the lawn mower on a flat level surface.
Unscrew the oil dip stick (12) 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 (12) again and read off the oil level while holding horizontally. The oil level must be between the maximum and the minimum

Changing the oil Fig. 23

Change the engine oil every year before the start of the season when the engine is warm.
Use only engine oil (SAE30).
Empty the fuel tank (with a petrol suction pump)
Place a flat oil drip tray in front of the mower (min. volume 1 Litre).
Remove the dipstick and tip over the mower until the whole oil is run out into the oil drip tray.
Fill up with engine oil as far as the top mark on the dipstick (approx. 0.47 l).
Important! Do not screw in the oil dipstick to check the oil level – only insert it as far as the thread.

Dispose of the used oil in accordance with applicable regulations.
Cleaning the belts (Fig. 17, 19)

Remove the knife and the gear housing by loosen-ing the screws out.
Clean the elements of the transmission and the belt once or twice a year with brush or compressed air.
Screw the transmission housing and the knife on again.

Care and adjustment of the cables
Oil the cables at regular intervals and check that they move easily.
Maintenance of the air filter (Fig. 20)
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.
Unclip the air filter cover and remove the sponge filter element. To avoid objects falling into the air intake, replace the air filter cover. (Fig. 20).
Important: Never clean the air filter with petrol or in-flammable cleaning agents. Clean the air filter with compressed air or simply by knocking out any soiling.
Maintenance of the spark plug (Fig. 21)
Check the spark plug for dirt and grime after 10 hours of operation and if necessary clean it with a copper wire brush. Thereafter service the spark plug after every 50 hours of operation.
Pull off the spark plug boot with a twist. Remove the spark plug (10) with a spark plug wrench.
Using a feeler gauge, set the gap to 0.75 mm( 0.030”).
Refit the spark plug taking care not to overtighten.
Engine brake lever (Fig. 1)
The engine is equipped with a mechanical brake (3) which has to be checked regularly. When releasing the brake lever, the blade must come to a halt within 7 seconds. If this is not the case, the machine must not be used. Contact an authorised specialist retailer.
Ensure that the machine is in a flawless condition for its entire service life. Improper maintenance may lead to life-threatening injuries.
