1. Product Overview

The EBERTH 6.5 HP / 4.8 kW gasoline engine is a robust and reliable four-stroke, single-cylinder engine with a 196 cm³ displacement. Designed for various applications, it features air cooling and a cable start mechanism. The engine operates efficiently at a maximum of 3600 rpm and includes an oil shortage safety system that automatically shuts down the engine if the oil level is too low, protecting it from damage.

This engine is suitable as a drive unit for a wide range of machinery, including go-karts, lawnmowers, lawn tractors, vibratory plates, power generators, snow blowers, log splitters, garden tillers, and cultivators. Its 19.05 mm diameter left-rotating shaft ensures compatibility with many existing setups. The package includes essential tools for initial commissioning and ongoing maintenance.

2.2 Adding Engine Oil

The engine is shipped without oil. It is essential to fill the crankcase with the recommended engine oil before the first start. Refer to the specifications for the correct oil type and capacity.

1. Place the engine on a level surface.
2. Remove the oil filler cap/dipstick.
3. Slowly add the recommended oil until it reaches the upper mark on the dipstick. Do not overfill.
4. Securely replace the oil filler cap/dipstick.

2.3 Adding Fuel

Use only unleaded gasoline with an octane rating of 95 RON or higher. The fuel tank capacity is 3.6 liters.

1. Ensure the engine is off and cool.
2. Open the fuel tank cap.
3. Fill the tank slowly, avoiding spills. Do not fill above the filter screen or to the very top of the tank to allow for fuel expansion.
4. Securely close the fuel tank cap.

2. Open the fuel valve.
3. Move the choke lever to the 'CLOSED' position (for cold starts). For warm starts, the choke may not be necessary.
4. Set the engine switch to 'ON'.
5. Pull the recoil starter handle slowly until resistance is felt, then pull firmly and quickly. Do not let the rope snap back; guide it gently.
6. Once the engine starts, gradually move the choke lever to the 'OPEN' position.
7. Allow the engine to warm up for a few minutes before applying load.

3.3 Stopping the Engine

1. Reduce engine speed to idle.
2. Set the engine switch to 'OFF'.
3. Close the fuel valve for storage or extended periods of non-use.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your EBERTH engine.

4.1 Daily Checks

• Check engine oil level.
• Inspect air filter for dirt.
• Check for any fuel or oil leaks.

4.2 Air Filter Maintenance

A dirty air filter can reduce engine performance and increase fuel consumption. Clean or replace the air filter regularly.

1. Remove the air filter cover.
2. Remove the foam filter element.
3. Wash the foam element in warm, soapy water, rinse thoroughly, and allow to air dry completely. Lightly oil the foam element with engine oil before reinstallation.
4. Replace the air filter element and cover.

4.3 Spark Plug Inspection and Cleaning

Inspect the spark plug periodically for wear and carbon buildup. Clean or replace as needed.

1. Remove the spark plug cap.
2. Use a spark plug wrench to remove the spark plug.
3. Inspect the electrode for wear and the insulator for cracks. Clean any carbon deposits with a wire brush.
4. Adjust the spark plug gap to the specified setting (refer to specifications).
5. Reinstall the spark plug and cap.

4.4 Oil Change

Change the engine oil after the first 20 hours of operation, then every 50-100 hours or annually, whichever comes first.

1. Run the engine for a few minutes to warm the oil.
2. Place a suitable container under the oil drain plug.
3. Remove the oil filler cap/dipstick and the oil drain plug to allow the oil to drain completely.
4. Reinstall the oil drain plug and fill with new, recommended engine oil (refer to Section 2.2).
