Our series of air-cooled four-stroke gasoline engines has been developed in terms of material and energy saving. Due to their compact design, the devices are easy to carry to every location and convenient to handle. They offer a wide range of applications in the fields of craft, industry, horticulture and agriculture, or household. This manual will help you use your engine optimally. Please read it carefully before using the device. By doing so, the life of the device will be significantly increased. Please contact us if you have any questions or comments about these instructions. In some cases, the device equipment may vary from the kind described in this guide.
Safety precautions
Please follow the following tips and ideas for your own safety, otherwise damage to the equipment or operator’s injury may occur.
- Make sure that the engine is only operated in well-ventilated environments, otherwise a health risk may occur because of the fumes.
- In other persons’ vicinity, the engine must work with due diligence. Make sure that the exhaust pipe is free and accessible; it must not be covered or blocked.
- Before filling the tank with fuel, the engine must always be switched off.
- The tank must not be overfilled.
- If the fuel is spilled on the device when filling, it must be removed before starting the engine.
- Before changing the oil make sure that the cap of the tank is closed, so no oil can go into the petrol tank.
- Do not use the unit near open flames, flammable or explosive substances or gases, and flying sparks.
- The engine should be at least one 1 m away from house walls or other fixed facilities.
- Make sure that all moving and rotating parts are covered.
- While the device works, the individual components (e.g., the exhaust) become hot. Be careful when touching, because otherwise it may cause burns.
- Operate in a safe environment and keep children away from it while operating.
- Operate on a straight and solid surface. On slopes the device may leak fuel.
- A larger inclination can have, even with full oil level, negative influence on the gear.
- Take care when transporting the device; make sure there are no fuel leaks. We recommend that the tank is emptied and the fuel inlet valve closed.
Before commissioning the device keep the following advice in mind:
- Make sure that all fuel lines are connected and firmly attached, so that no leakage may occur.
- Make sure that all screws and nuts are firmly tightened.
- Check the fuel and oil level and if necessary, re-fill fuel or oil.

Starting and stopping the engine
Open the throttle (1) and the drain screw (3) of the carburettor. Once the fuel runs out, the drain screw (3) may be refastened. Then you can start the engine as usual.

The engine may be run only within the rated power and rated speed. If you detect abnormal episodes, please stop the engine immediately and initiate corrective measures. The engine should not be charged during the first 1–3 min after the start.

If you want to stop the engine, reduce the speed to a minimum, set the choke to Off and turn the on/off switch to off. The engine should be shut immediately. The switch is located right on the crankshaft housing.
Regular maintenance
- Regularly clean the air filter; replace it in case it cannot be cleaned any more. It should be cleaned after approximately 25 hours of working.
- Check all fittings for tightness and re-tighten them if necessary.
- Regularly check the engine oil level.

Every 50 hours of operation, the spark plug should be cleaned, tested, or replaced if necessary. If the earth electrode is burnt too much or the spark plug worn, it should be exchanged against a new spark plug of the same type. Only mount or dismount spark plugs in a cold engine. ONLY use ORIGINAL spark plugs! 
| № | Instruction/name |

Clean the fuel tank every 100 hours of operation. For this, the tank should be taken from the holder and rinsed. The fuel filter should periodically be cleaned.
If the engine shall be stored for long periods of time, the fuel tank shall be completely emptied and the carburettor emptied on his discharge screw. The engine oil should be discharged when the engine is hot, but switched off. Then re-fill new oil. The engine should be completely cleaned of dirt from the outside. The air filter and spark plug should be checked again and replaced or cleaned if necessary. The combustion chamber should be filled with some motor oil when the spark plug is unscrewed so that the combustion chamber is not oxidised. After that, the engine may be stored in a dry storage place.
