Safety

Ensure you have read and fully understood the instruction manual and safety advice before using this product.
Only operate the scythe mower if you are trained, competent, and physically fit to handle motorised garden equipment.
Always wear appropriate personal protective equipment (PPE), including safety goggles, hearing protection, protective gloves, long trousers, and steel-toe capped boots.
Do not allow children or untrained individuals to operate or be near the mower during use.
Keep all bystanders, pets, and observers at a minimum safe distance of 15 metres during operation to avoid injury from flying debris.
Before starting the mower, thoroughly inspect the mowing area and remove stones, sticks, wire, and any other foreign objects that could become dangerous projectiles.
Never attempt to adjust, clean, or remove debris from the blade or mower deck while the machine is running. Always switch off the engine and wait for all moving parts to come to a complete stop.
Use extreme caution when handling the cutting blade. It remains sharp even when not in motion and may cause serious injury if handled improperly.
Never insert hands or feet near the blade housing or discharge opening during operation or maintenance.
Ensure the scythe mower is on stable, level ground before starting or adjusting the machine.
Do not use the mower on steep slopes, excessively uneven surfaces, or slippery ground to reduce the risk of losing control or slipping.
Use correct manual handling techniques when lifting or moving the mower. Do not attempt to lift the mower alone if it exceeds safe individual lifting limits.
Avoid overexertion by taking regular breaks during extended use. Fatigue increases the risk of injury.
Always operate the mower at the recommended engine speed. Do not modify the engine or alter safety features.
Regularly inspect the mower for damage, loose bolts, worn blades, or other signs of wear and tear. Replace damaged or worn parts before use.
Store the mower in a dry, well-ventilated area away from flammable materials and inaccessible to unauthorised persons.
Refuel the mower only when the engine is off, cool, and in a well-ventilated outdoor area. Wipe up any fuel spills immediately and never smoke or use open flames nearby.
Keep hands, clothing, hair, and tools away from moving parts during operation. Tie back long hair and avoid loose-fitting clothing.
Never leave the machine unattended while it is running. Always turn it off completely before walking away.
Do not use the mower if safety guards or protective covers are missing or damaged.
Check oil and fuel levels before each use and only use fuel and lubricants recommended by the manufacturer.
Ensure all fasteners are tightened before use and after any maintenance. Loose parts can lead to malfunction and serious injury.
Do not use the mower in poor visibility, at night, or during adverse weather conditions such as rain or strong wind.
Keep all maintenance and repair records up to date and retain proof of servicing to demonstrate responsible use and care.

Engine Safety

When Adding the Fuel:

Turn engine OFF and let engine cool at least 2 minutes before removing petrol cap.
Fill petrol tank outdoors or in well-ventilated area.
Do not overfill petrol tank. Fill tank to approximately 1-1/2 inches below top of neck to allow for fuel expansion.
Keep petrol away from sparks, open flames, pilot lights, heat, and other ignition sources.
Check petrol lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.

When Starting the Engine:

Make sure spark plug, muffler, petrol cap and air cleaner are in place.
Do not crank engine with spark plug removed.
If petrol spills, wait until it evaporates before starting engine.
If engine floods, set choke to OPEN/RUN position, place throttle in FAST and crank until engine starts.
If there is a petrol leakage in the area, do not start the engine.
Do not use pressurized starting fluids because vapour's are flammable.

When Operating Equipment:

Do not tip engine or equipment at angle which causes petrol to spill.
Do not choke carburettor to stop engine.
Running engines produce heat. Engine parts, especially the muffler, can become extremely hot. Severe thermal burns can occur on contact. Combustible debris, such as leaves, grass etc. can catch fire.
Allow muffler, engine cylinder and fins to cool before touching.
Remove accumulated combustibles from muffler area and cylinder area.
Wear appropriate hearing protection and goggles while working with the product! Wearing hearing protection reduces the risk of injury.

When Transporting Equipment:

Transport with the petrol tank EMPTY or with the petrol shut-off valve OFF

When Storing Petrol Or Equipment With Petrol In the Tank:

Store away from furnaces, stoves, water heaters or other appliances that have pilot light or other ignition source because they can ignite petrol vapors.
Allow the motor to cool down before storing product in enclosed spaces.
While petrol is in the tank, never store the product in a building in which petrol vapours may come into contact with naked flames or sparks or can be easily ignited.

Maintenance

Always make sure that all nuts, bolts and screws are firmly tightened. This will ensure that the product is in a safe working condition.
Should the tank need draining, do this outdoors.
Check the petrol system for leaks or defective parts on a regular basis.
Carefully remove overflowing petrol without delay.
Use only genuine spare parts. Only these spare parts are designed and suitable for the product. The use of other spare parts not only invalidates the warranty, it also presents a danger to yourself and your environment.
Always visually examine the cutting tool before use to make sure it is not worn or damaged.
Replace damaged exhaust silencers.
Careful handling and regular cleaning ensure that the product remains functional and efficient for a long time.
Clean the product immediately after each use. Dried-on grass is extremely hard and difficult to remove.
Brush off coarse dirt.
Wipe down the product with a slightly damp cloth.
Never spray the product with water or expose it to water.
Never use cleaning agents or solvents.
Keep ventilation slots clean and free of dust.
