OPERATION

Filling with engine oil

IMPORTANT! The following procedures and adjustments must be performed before the engine is started. Do not attempt to make any of these adjustments while the engine is running.

This engine is shipped without oil or petrol, any oil residue is from testing prior to shipping. The engine must be filled with the correct grade of oil and petrol before starting the engine. Running the engine with a low oil level will cause irreparable engine damage. Always use high-quality engine oil classified SAE 30 oil (or equivalent, e.g. 5W 30, often termed as 4-stroke lawnmower oil). Only use additives recommended by the engine manufacturer. To prolong the life of your engine, it is important that the oil is changed after the first 5 hours of use.

Check the engine oil level with the engine stopped and the mower on a level surface.

1. Remove the oil filler dipstick and wipe oil from it with a clean cloth.
2. Insert the dipstick into the oil filler neck and screw it in.
3. Remove the dipstick and check the oil level. The oil level must be between the min. and max. marks on the dipstick. If near the lower level, fill to the upper level with the recommended oil (SAE 30 or equivalent). Do not overfill. Wipe away any spilt oil. ( Fig. J )
4. Before using for the first time, add 0.5 litres of oil (SAE 30).

Filling with engine fuel (Fig. K)

WARNING!
Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where the engine is refueled or where petrol is stored. Avoid repeated or prolonged contact with skin or inhalation of vapour.

CAUTION!
Petrol is highly flammable and extreme caution must be taken when handling or working with it. Keep out of reach of children.

1. Clean the area around the petrol filler cap before removing. Check the fuel level.
2. Refill the tank if the fuel level is low.
3. Always use clean, fresh unleaded petrol and purchase fuel in quantities that can be used within 30 days.

Never mix oil with petrol.
To allow for expansion, carefully refuel and avoid overfilling or spillage. There should be no fuel in the filler neck.
Clean up any overflow or splashes of petrol before starting the engine.
Ensure filler cap is secure after filling.

Setting the cutting height (Fig. L)

WARNING!
The blade can cause serious injury. Before adjusting the mower height, stop the engine and wait for the mower blade to come to a complete stop.

1. Pull the lever towards the wheel, then move it forward or backward to adjust the cutting height.
2. Move it to any one of the 7 positions for the desired cutting height.
3. Return the lever to the securing plate.

NOTE: Never use the lowest cutting height for the first cut of the season or in drought conditions. Only about one third of the grass height should be cut at this time.

Starting the engine

WARNING!
Do not operate the machine in enclosed or poorly-ventilated areas, as the exhaust gas contains toxic substances. Keep hands, feet, hair and clothing away from all the moving parts of the machine. The exhaust and other parts of the machine will become hot during use. Make sure that the blade is securely fastened before starting the engine.

1. When starting a cold engine, press down the primer 3-5 times. ( Fig. M )
   Pressing the primer button too many times can cause the engine to flood.
   NOTE: When starting a warm engine, the primer does not need to be used. If the engine stops due to a lack of petrol, refill and press the primer 3-5 times.

2. Start/stop bar activation
   Pull the start/stop bar towards you. ( Fig. N )

3. Pull cord handle
   With the right hand, slowly but firmly pull the starter handle and rope from the pull cord guide until you feel resistance, then pull briskly. If the engine fails to start after three pulls, repeat the start process. When the engine starts, return the starter rope to the rope guide gently.

To stop, release stop/start bar

Failure to start
If the engine won’t start after you have operated the starter several times, the engine may be flooded with excess fuel.
Use the following procedure to clean and start a flooded engine:
A. Release the stop/start bar.
B. Remove the spark plug, dry and replace. Install the spark plug carefully by hand to avoid cross-threading. After the plug is seated, tighten it 1/8 to 1/4 turns with the socket spanner to compress the washer.
C. Pull the stop/start bar towards the upper handle.
D. Operate the starter, as described above.

Using the Self-propelled function

1. This lawnmower equipped with self-propelled system.
2. Push the self-propelled rear switch bar towards the handle and hold it in position. The lawnmower will start to move automatically. ( Fig. O )
3. To stop the moving lawnmower, simply release the drive.

Mowing with collection bag

WARNING!
Always observe the strictest safety procedures when using the lawnmower.

Start the engine and allow it to run.
Keep a firm grip on the upper handle and stop/start bar and walk along with it. Never run with the mower. Be very careful when mowing uneven or rough ground. Maintain a stable footing. Mow across slopes, never up and down. Be careful when changing the direction of the mower on a slope. Do not use the mower on a steep slope of more than 15°.

NOTE:
The best results are achieved when the grass is dry. Wet grass will clog the blade and the grass collection system.
Grass grows at different rates at different times of the year. Never use the lowest cutting height for the first cut of the season or in drought conditions. Only about one third of the grass height should be cut.
If the lawnmower will not collect the cuttings efficiently, the grass discharge chute may be blocked, the grass bag may be full or the underside of the mower deck may be clogged.

Function of full indicator (Fig. P)
If the grass bag is empty or it is not filled with grass, the grass full indicator will be open. If the grass bag is filled with grass the grass full indicator will be closed.

Emptying the grass bag

Raise the discharge flap with one hand and remove the grass bag using its handle with your other hand. To maintain safety, the discharge flap will close back to cover the mulching plug when released.
Empty the grass clippings from the collection bag and refit. If grass is caught in the discharge chute, clean it using a nylon-bristled brush.

Mowing with mulching

When mulching, remove the grass collection bag and insert the plastic mulching plug into the rear discharge chute. Release the flap to cover the plug.
NOTE: To ensure that the cut grass can be mulched efficiently, do not cut high or wet grass

MAINTENANCE AND STORAGE

Storing the lawnmower for short periods

After mowing, please follow the actions below prior to placing the lawnmower in storage:
– Allow the engine to fully cool.
– Ensure the grass bag is empty.
– Clean all debris from under the mower deck.
Store the lawnmower on a flat and level surface with all 4 wheels on the ground. Store in a dry, safe place which is not accessible by children or people who are not familiar with operation.

Storing the lawnmower for extended periods

CAUTION! Do not empty the petrol tank in enclosed areas, near fire or when smoking. Petrol fumes can cause explosions and fire. Always carry the product using its gripping surfaces.
If the lawnmower is to be placed into storage at the end of the season, or if the mower is not to be used for a period longer than 6 weeks, storage maintenance must be performed on the lawnmower.
Temperature fluctuations cause condensation, which contaminates fuel and causes starting problems. Simply emptying the machine of fuel will prevent this.
Empty the petrol tank with a petrol suction pump, if available, or use the tipping method.
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. 20ml of oil from an oil can. Slowly pull back the starter handle, which will bathe the cylinder wall with oil, and 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 schedule

WARNING!
Before you tip the lawnmower onto its side, completely empty the fuel tank using a petrol suction pump.
Never turn the mower upside down.
Before commencing any maintenance, always disconnect the spark plug.
Performing routine maintenance correctly on your lawnmower will ensure you get years of trouble-free use.
Please keep this manual safe for future reference.
It is recommended that the following maintenance schedule is adhered to. This will ensure the lawnmower operates correctly and is safe to use.

Cleaning

1. To ensure long life and good performance of the machine, it is important to keep the machine clean and well lubricated. Make sure the chute is clean and under the deck is cleared from wet debris (see also short term storage).
2. Do not allow grass cuttings and other debris to become dry and hard on any of the mower surfaces, as this will directly affect the cutting and grass collection performance. Make sure that the underside of the lawnmower deck is clean and clear.
3. Never clean the lawnmower with a water jet or high-pressure cleaner. The engine must remain dry. Do not use aggressive cleaning agents or solvents, such as cold degreasers or petroleum ether.

Cleaning or replacing the air filter

WARNING!
Never run the engine without the air filter element installed:

1. Loosen the fastener that holds the cover.
2. Open the cover and remove the filter.
3. To loosen debris, gently tap the filter on a hard surface. If the filter is excessively dirty, replace with a new filter.
4. Install the filter.
5. Insert the cover tabs into the slots.
6. Close the cover and secure with the fastener.

Cleaning or replacing the spark plug

1. Once the engine has cooled, pull off the spark plug boot with a twist. Remove the spark plug using the socket spanner supplied.
2. Clean the plug with a wire brush.
3. Using a feeler gauge, set the gap to 0.51mm.
4. Install the spark plug carefully by hand to avoid cross-threading.
5. After the spark plug is seated, tighten with the spanner to compress the washer.

Changing the oil

Tilt the lawnmower towards the oil filler, have a container ready to catch the oil and remove the dipstick. Once the oil has been emptied, wipe up any spillages.
Refill with 470ml SAE 30 oil or equivalent, i.e. SAE 5W/30, SAE 10W/30). When the dipstick is rested on the filler pipe, the oil level must be between the min. and max. marks on the dipstick.

See `Filling with engine oil’. Do not overfill.
Start the engine and allow it to run briefly.
Stop the engine, wait one minute and check the oil level. Top up if necessary.

Replacing the cutting blade (Fig. Q)

WARNING! USE GLOVES.

Before you remove the grass collection bag, stop the engine and wait until the blade has come to a complete stop.
You will need garden gloves (not provided) and a spanner wrench to remove the blade. Always handle the blade with care – sharp edges can cause injury.
Do not hold the blade with bare hands.

Renew your blade after 36 hours of mowing or after 2 years, whichever comes first, regardless of condition.
Regularly check your blade. If the cut of your grass is poor, the blade might be blunt.
Damaged blades not only result in a bad cut, they cause excessive vibration and uneconomical running of the engine. If the blade has worn excessively and become pitted and blunt, it should be replaced or sharpened.

Tip the machine slightly towards the oil filler pipe and reach under the deck.
Hold the blade and unscrew the blade bolt counterclockwise using a spanner wrench. Remove the washer and the blade.
Inspect the blade adaptor for any signs of damage.
Fit a new blade, position the blade on the two studs on the blade flange and then replace the washer and bolts.

Check the washer is still slightly domed to keep the pressure on the bolt to stop it unwinding, keeping the blade secure. Then replace the washer (right way round!) and bolts.
Make sure the blade is correctly positioned and then firmly tighten the bolt. Do not over tighten. The up turn of the blade must project into the motor compartment.
