Refueling:
Note: Two-stroke motor, mixing ratio 1:40 FOLLOW THE SAFETY PRECAUTIONS! Be careful and cautious when handling fuels.
- The engine must be switched off!
- Thoroughly clean the area around the caps, to prevent dirt from getting into the fuel or oil tank.
- Remove the fuel cap and carefully fill the fuel mixture up to the lower edge of the filler neck.
- Be careful not to spill fuel!
- Tighten the tank cap as far as it will go.
- After refuelling, clean the tank cap and surroundings and make sure the cap is sealed!
NOTE:
Always pre-mix the intended oil volume in half of the fuel volume to produce the fuel/oil mixture and then add the remaining fuel volume. Shake the finished mixture well before filling the mixture into the auger. It is not wise to add more engine oil than specified to ensure safe operation. This will only result in a higher production of combustion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the muffler. In addition, fuel consumption will rise and performance will decrease.
The storage of fuel
Fuels have a limited storage life. Fuel and fuel mixtures age through evaporation, especially at high temperatures. Aged fuel and fuel mixtures can cause starting problems and damage the engine.Purchase only that amount of fuel, which will be consumed over the next few months. At high temperatures, once fuel has been mixed it should be used up in 6-8 weeks. Store fuel only in proper containers, in dry, cool, secure locations!
Avoid skin and eye contact!
Mineral oil products degrease your skin. If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate. Various skin deseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil. If oil comes into your eyes, immediately wash them with clear water. If your eyes are still irritated, see a doctor immediately! Check fuel lines, fuel tank cap and fuel tank for leakages or tears. Do not start the machine with such damage. Do not refuel the machine when the motor is still hot or running. Never refuel the machine close to an open flame. Period of use: Using the earth auger can lead to poor circulation in the fingers, hands or wrists. Symptoms such as pins and needles, pain, stinging and changes in the skin can occur. If these symptoms occur, seek medical help. Use appropriate gloves and take regular breaks.

Warning!
In case of extended working periods, the operating personnel may suffer circulatory disturbances in their hands (vibration white finger) due to vibrations. Raynaud‘s syndrome is a vascular disease that causes the small blood vessels on the fingers and toes to cramp in spasms. The affected areas are no longer supplied with sufficient blood and therefore appear extremely pale. The frequent use of vibrating devices can cause nerve damage in people whose circulation is impaired (e.g. smokers, diabetics). If you notice unusual adverse effects, stop working immediately and seek medical advice. Observe the following information to reduce hazards:
- Keep your body and especially your hands warm in cold weather.
- Take regular breaks and move your hands to promote circulation.
- Ensure as little vibration as possible at the machine via regular maintenance and stable parts on the device.
Before operation
Assembly
For packaging reasons, your machine has not been assembled completely.
Inserting the earth auger
- Place the motor casing on a work bench. Place the earth auger (7) on the drive shaft (6), ensuring that both holes are aligned.
- Insert the locking pin (A).
Fuelling
- Open the fuel tank cap (15).
- Pour in the fuel mixture using a funnel.
- Do not fill the tank completely as fuel expands.
- Close the fuel tank cap (15) tightly and clean the area from possibly spilled fuel mixture.
Fuel mixture
The auger‘s motor is a two-stroke motor. It is driven by a 1:40 fuel mixture made up of two-stroke oil and fuel. The fuel requires unleaded ordinary petrol with a research octane count of at least 91. Lubrication of the motor takes place by adding premium two-stroke oil. Do not mix the fuel mixture in the fuel tank. Use the mixing container supplied or another appropriate container. Only pour the fuel mixture into the fuel tank after previously mixing and stirring it well.
- Use fresh, clean fuel. Water and contaminants in the petrol damage the fuel system.
- Refuel in a well-ventilated area with the motor not running. If the motor was in use directly prior to refuelling, leave it to cool down first. Never refuel the machine in a building where the petrol fumes can reach flames or sparks.
- Petrol is highly flammable and explosive. When handling fuel, you may suffer burns or other severe injuries.
- Turn off the motor and keep away from heat, sparks and flames.
- Only ever refuel outside.
- Wipe up spilled petrol straight away.
Starter cord
Pulling the cord (9) starts the motor.
Choke lever
The choke lever (C) closes and opens the choke in the carburetor. In the
position, the air-petrol mixture is enriched for the motor‘s cold start. The
position is used for the operation of the motor and for a warm start.
Idle setting screw
Using screw (5), the auger‘s idling mixture can be adjusted. If the idling mixture is a little too high (the boring head turn by itself in idle mode), the idling mixture can be reduced by slowly turning the screw anti- clockwise. Warning! Other work on the carburettor must be carried out by a specialist.
