2. Remove and clean the oil dipstick.
3. Insert the dipstick into the oil filler neck and pull it out to check the oil level.
4. If the oil level is too low, open the oil filler cap and fill with the recommended engine oil up to the upper mark on the oil dipstick.
5. Then refit the oil dipstick and the oil filler plug.

Important!

• Damage caused by operating a petrol engine with an insufficient oil level is not covered by the warranty.
• If the oil level falls below the lower safety limit, the engine may come to a standstill or even be damaged. To avoid accidental burn-out, it is important to check the oil level before every start. This should be carried out every few months to ensure the long-term protection of the engine.

Oil change
Changing the oil is quick and easy when the petrol engine is warm.

1. Place a suitable container under the petrol engine to collect the used oil. Remove the oil pressure sensor, the drain plug, and the seal.

2.  Drain the residual oil completely, then insert the drain plug and a new seal and tighten them.
   Important! When disposing of used oil, the environment must not be polluted. We recommend collecting the used oil in a container and taking it to a recycling centre or recycling workshop. Do not dispose of it in household waste, do not pour it on the floor, do not dispose of it in the sewage system!

3. Position the petrol engine horizontally and fill with the recommended oil up to the upper mark on the dipstick.

4. Then reinsert the oil pressure sensor and tighten it.

Replacing the oil filter

1. Drain the oil and then retighten the oil drain plug.

Hints and recommendations
Storage

1. Preparing for storage : Proper preparation for storage is important to prevent damage to the petrol engine and to maintain its appearance. Observe the following points to prevent corrosion and rust, keep the performance and appearance of the engine in good condition, and ensure a smooth restart.
2. Cleaning: Allow the petrol engine to cool down for at least 30 min after switching it off before cleaning it. Remove dirt from the entire exterior surface, repair damage to the paint, and apply a thin layer of oil to prevent rusting.

Important! If you clean the petrol engine with a hose or a high-pressure cleaner, there is a possibility that water can penetrate through the openings of the air filter or the silencer. The water may get into the air-filter element and from there into the air filter or silencer, which can damage the cylinder.
Fuel

• Petrol can oxidise and spoil during storage. Prolonged storage of petrol leads to starting diffi-culties and gelatine-like deposits. If the petrol in the engine deteriorates during storage, it is necessary to repair or replace the carburettor or another part of the fuel system.
• The service life of the petrol in the tank or carburettor depends on various factors, e.g., the mixing ratio, the storage temperature, and the filling level. The air in an unfilled tank can also cause the petrol to deteriorate more quickly, as can high temperatures. It is possible for petrol to spoil within 30 days or less, especially if the oil has become old.

Important! Any damage to the fuel system or loss of performance of the petrol engine due to improper storage by the user is not covered by the warranty.
Draining fuel from the fuel tank and carburettor

Warning!

• Petrol is highly flammable and explosive and can cause severe burns if handled incorrectly.
• Keep the petrol away from heat sources, sparks, or naked flames.
•  In the event of spillage, remove the petrol immediately.
  1. Remove the fuel line attached to the side of the petrol engine and drain the fuel from the fuel tank into a container provided for this purpose. If the fuel tank is equipped with a fuel tap, turn the fuel tap to “ON” to drain the fuel. After you have completely drained the fuel, reconnect the fuel line.
  2. Loosen the carburettor drain plug to drain the remaining oil into a container and then retighten the drain plug.

Motor oil

1. Replace the engine oil.
2. Remove spark plug.
3.  Fill about 5–10 ml of new engine oil into each cylinder.
4. Set the petrol engine switch to “ON” and hold it down for a few seconds so that the oil is dis-tributed in the cylinder.
5. Refit the spark plug.

Storage warning

• If you store your petrol engine and there is still petrol in the fuel tank or carburettor, you must ensure that the petrol vapours do not ignite and cause a serious accident. Choose a well-venti-lated storage location and keep away from all appliances that can produce an open flame, e.g., heaters, water heaters, tumble dryers. Also avoid starters or other power consumers that can generate sparks.
• Avoid places with high humidity as far as possible, as appliances located there are very susceptible to rust and corrosion.
• Store the petrol engine horizontally. Avoid tilting it to prevent fuel or oil leaks.
• If the fuel remains in the tank, set the fuel tap to “OFF” to prevent leakage.
• Cover the cooled petrol engine and the exhaust system to prevent dust deposits.
• Some flammable materials can be ignited or melt by the hot petrol engine and exhaust system. It is important not to cover the engine with plastic film, as the impermeable films allow ambient moisture to condense, which can accelerate rust and corrosion. If the engine is equipped with a battery, it is recommended that the battery is removed and stored in a cool, dry place and charged monthly to extend its service life.

Retrieving from storage

• Check the petrol engine according to the instructions in the section “Inspection before commissioning.”
• If the fuel has been drained before storage, fill the fuel tank with new petrol and check the tank to ensure that the petrol is clean. Over time, petrol can oxidise or go bad, making it difficult to start the engine.
• It is normal for a petrol engine to emit smoke when starting if preservative oil has been applied to the outside of the cylinder.

Transport

• If the petrol engine has just been running, it should cool down for at least 15 min before it is loaded onto the transport vehicle. A hot petrol engine and a hot exhaust system can endanger people and flammable materials in the vicinity.
• The petrol engine should be kept level to prevent oil from leaking during transport. If the fuel tank has a fuel tap, this should be turned to “OFF.”

Connection between starter motor and battery

• Recommended battery: 12 V/45 Ah
• Make sure that the battery cables are not connected in reverse order, otherwise a short circuit may occur. First connect the positive cable to the battery and then the negative cables so that accidental contact between positive and earth does not cause a short circuit.

Warning!

• Incorrect handling can cause the battery to explode and cause serious injury to people in the vicinity.
• Keep the battery away from sparks, flames, and other flammable materials.

Important! The battery terminals, clamps, and corresponding accessories contain lead and lead com-pounds. Wash your hands after touching them.

1. Connect the positive cable of the battery to the start relay.
2. Connect the negative cable of the battery to the fastening screw of the petrol engine, the ground screw, or another well-grounded connection point.
3. Connect the positive cable of the battery to the positive terminal of the battery as shown.
4. Connect the negative cable of the battery to the negative terminal of the battery.
5. Apply grease to the poles and cable ends.

Carburettor change for high altitudes

• At higher altitudes, the standard mixture ratio for the carburettor is too rich, which leads to a reduction in performance and increased fuel consumption. A mixture that is too rich also leads to contamination of the spark plug, which can cause starting difficulties. When operating a petrol engine at different altitudes, exhaust emissions increase with the operating time.
• The performance of a petrol engine can be improved at high altitudes by adjusting the carburet-tor. If the engine is operated permanently at high altitudes (≥ 1500 m), please contact a specialist to adjust the carburettor. However, the output decreases by 3.5 % every 300 m above sea level. If the carburettor is not adjusted, the performance drops even more.

Important! The carburettor must be correctly adjusted so that it is adapted to the conditions at high altitudes. A petrol engine with an incorrectly adjusted carburettor cannot be used in areas with low altitudes (< 1500 m) as the fuel mixture is too weak. This can cause the motor to overheat and cause serious damage. Please contact a specialist to have the carburettor setting adjusted before using the petrol engine at low altitudes.
