4. Opsætning og montering

The HECHT 752 tiller requires some assembly before first use. Follow these general steps:

1. Udpakning: Carefully remove all components from the packaging. Check for any damage during transit and ensure all parts are present according to the packing list.
2. Håndtagssamling: Attach the upper and lower handle sections to the main unit using the provided bolts and knobs. Ensure they are securely tightened.
3. Hjulfastgørelse: Install the transport wheels. These wheels aid in moving the tiller to and from the work area and can be adjusted for tilling depth.
4. Brændstofforberedelse: This is a 2-stroke engine. It requires a specific mixture of gasoline and 2-stroke engine oil. Refer to the engine specifications for the correct mixing ratio (e.g., 1:25 or 1:50). Mix the fuel in a separate, approved container before pouring it into the fuel tank. Do not use pure gasoline.
5. Indledende kontrol: Before starting, ensure all connections are secure, the spark plug is properly seated, and there are no fuel leaks.

5. Betjeningsvejledning

5.1. Tankning

1. Sørg for, at motoren er slukket og afkølet.
2. Flyt til et godt ventileret udendørs område.
3. Åbn forsigtigt brændstoftankens dæksel.
4. Pour the pre-mixed gasoline-oil fuel into the tank, avoiding overfilling.
5. Luk brændstoftankens dæksel forsvarligt.

5.2. Start af motoren

1. Placer rorfræseren på en flad, stabil overflade.
2. Ensure the tines are not in contact with the ground or any obstacles.
3. Set the choke lever to the 'START' or 'CHOKE' position (if applicable).
4. Tryk flere gange på primerpumpen, indtil brændstoffet er synligt.
5. Hold the tiller firmly with one hand on the handle.
6. Pull the starting handle cord with a smooth, steady motion until the engine starts.
7. Når motoren starter, skal du gradvist flytte chokerhåndtaget til 'RUN'-positionen.

5.3. Jordbearbejdning

1. With the engine running, engage the tines (if there's a clutch lever).
2. Guide the tiller slowly into the soil. The 250 mm working width allows for efficient coverage.
3. Allow the tines to penetrate the soil. Do not force the machine.
4. Move the tiller forward in a controlled manner, overlapping passes slightly to ensure complete cultivation.
5. For deeper cultivation, make multiple passes, gradually increasing the depth.

6. Vedligeholdelse

Regelmæssig vedligeholdelse sikrer din jordfræsers levetid og optimale ydeevne.

• Rensning: After each use, clean the tiller, especially the tines and engine cooling fins, to remove soil, debris, and plant matter. Use a brush or cloth. Do not use high-pressure water directly on the engine.
• Tændrør: Periodically inspect the spark plug for wear or fouling. Clean or replace as necessary. The recommended electrode gap is 0.6 - 0.8 mm.
• Luftfilter: Check and clean the air filter regularly. A clogged air filter can reduce engine performance.
• Brændstofsystem: For long-term storage, drain the fuel tank and run the engine until it stops to clear the carburetor of fuel. This prevents fuel degradation and gumming.
• Bladinspektion: Inspect the tines for wear, damage, or looseness. Replace worn blades to maintain effective tilling.
• Smøring: Refer to the product diagram for any lubrication points and apply appropriate grease or oil as recommended.
• Generel inspektion: Regularly check all nuts, bolts, and fasteners for tightness. Tighten any loose components.
