• Hand starter and electronic starter
• Powerful cooling system
• TCI ignition module
• Fan guard made from special low-noise steel sheet

The leading point in the development of our series of air-cooled 4-stroke petrol engines has been the protection of material and saving of energy. By their compact design, the devices are easy to transport to every location and comfortable to handle. They offer the user a broad range of applications, including artisanry, industry, horticulture, agriculture, and household.
This user’s manual will assist you in optimally using the engine. Read it thoroughly before putting the device into operation. This will increase the lifetime of your device considerably.
Do not hesitate to contact us if you have any questions or proposals concerning this user’s manual. In some cases, the equipment of the device might vary from that described in the user’s manual present

Safety instructions

For your own safety, obey the following instructions, for otherwise material damage and/or personal injuries might result.

• Make sure that the engine is only operated in well-ventilated conditions; otherwise, the exhaust gases might be harmful to your health.
• Near other persons, only operate the engine with greatest care. Make sure that the exhaust pipe is free; it must not be covered, obstructed, or blocked.
• Before filling fuel into the tank, make sure to cut the engine off.
• The tank must not be filled to overflowing.
• In case fuel is spilled onto the casing of the device during filling fuel in, absolutely remove it before starting the engine.
• When exchanging the oil, make sure that the tank cover is closed lest oil get into the tank.
•  Do not operate the device near open flames, flammable or explosive materials or gases, and flying sparks.
• There should be a minimum distance of 1 m between the engine and the wall of a house or another permanent installation.
• Make sure that all moving and rotating parts are safely covered.
• During operation, certain components of the device (e.g., exhaust pipe) will heat up. When you touch these components, there is a risk of burns.
• Only operate the device in safe conditions and keep children away during operation.
• Only operate the engine on a level, solid surface. If inclined, fuel might leak.
• A major inclination (the device standing aslope) might impair the lubrication of the gearing mechanism even with full oil level.
• When transporting the engine, make sure that no fuel can escape. It is advisable to empty the tank and to close the fuel supply cock.

Connecting a battery (optional)

Only use 12 V batteries with a  minimum of 45 Ah. Connect them to the positive cable of the relay and the negative cable to the housing of the engine. Make sure that there is no corrosion on the cable. Should there be corrosion on the cable, remove it first

Attention!

• Only operate the engine in a well-ventilated area – with or without battery.
• Avoid any kind of flying sparks, open flames, or the like. Explosion hazard!
• Batteries contain sulphuric acid (electrolyte). Any contact with your skin or eyes can cause serious injuries. Wear suitable protection clothing. Contact the furnisher of the attery used to read up on suitable measures.

Before operating the device
1. Make sure that all fuel lines are properly connected and safely fixed lest there be a fuel leak.
2. Make sure that all fixing screws and nuts are well tightened.
3. Check the fuel and oil levels and top up oil or fuel if necessary.

Starting and stopping the engine
Open the choke (1) and untighten the drain screw (3) of the carburettor. As soon as fuel flows out, the drain screw (3) must be retightened. Afterwards, you can start the motor as usual.

OFF ON|  |  |

The motor may only be operated within the range of the rated performance and speed. Should you detect any abnormal operation behavior, immediately stop the engine and start remedial measures. The motor should not be charged within the first 1–3 min after starting.

If you wish to stop the engine, reduce the speed to its minimum, then turn the choke to off and the on/off switch to off. The motor will stop immediately. The switch is on the right side of the crankshaft gear housing.

Regular maintenance

• Regularly clean the air filter or replace it, should you not be able to clean it any longer. It should be cleaned after approx. 25 operation hours.
• Check all fixing screws for tightness and re-tighten them if necessary.

• Regularly check the motor oil level.

The spark plug should be cleaned, checked, replaced, after 50 operation hours, or re-adjusted following instructions if necessary. If the earth electrode is too heavily burnt or the spark plug is too heavily worn, the plug should be replaced by a new one of identical type. Only remove and install the spark plug with the engine being cold! ONLY use ORIGINAL spark plugs!

Clean the fuel tank after 100 operation hours. To do this, remove the tank and rinse its inside. The fuel pre-filter should be cleaned regularly.
Before the engine is stored for a long time, the fuel tank should be emptied entirely and the carburetor emptied via its drain screw (3). The motor oil should be drained in operation-warm condition (with the engine stopped!) and replaced with new oil. The exterior of the engine should be cleaned of dirt entirely.
The air filter and spark plug should be re-checked and replaced, if necessary, or cleaned/re-adjusted.

With the spark plug removed, the combustion chamber should be filled with a small quantity of oil to prevent oxidation. After these steps, the engine can be stored in a dry room.
