4. Setup and Installation
4.1 Unpacking
Carefully remove the engine from its packaging. Inspect for any shipping damage. Keep all packaging materials until you are sure the engine is in good working order.

4.2 Add Engine Oil
IMPORTANT: The engine is shipped WITHOUT oil. Failure to add the correct amount and type of oil before starting will result in permanent engine damage and void the warranty. Refer to the 'Specifications' section for oil capacity and recommended oil type.
- Place the engine on a level surface.
- Remove the oil filler cap/dipstick.
- Slowly add the recommended engine oil (refer to specifications for type and capacity) until the oil level reaches the upper mark on the dipstick. The elevated oil dipstick position facilitates this process.
- Securely replace the oil filler cap/dipstick.
4.3 Add Fuel
Use fresh, unleaded gasoline with an octane rating of 87 or higher. Do not use E85 fuel or mix oil with gasoline.
- Ensure the engine is off and cool.
- Remove the fuel tank cap.
- Fill the fuel tank carefully, avoiding overfilling. Leave space for fuel expansion.
- Securely replace the fuel tank cap.
4.4 Mounting the Engine
Mount the engine securely to the lawnmower deck or equipment frame using appropriate hardware. Ensure the vertical shaft is correctly aligned with the blade adapter or drive mechanism. Consult your lawnmower's specific instructions for mounting procedures.
5. Operating Instructions
5.1 Starting the Engine (Recoil Start)
- Ensure the engine has sufficient oil and fuel.
- Place the equipment on a firm, level surface.
- If equipped, ensure the engine switch is in the "ON" position.
- The engine features an auto-choke system, simplifying cold starts. No manual choke adjustment is typically required.
- Grasp the recoil starter handle firmly. Pull the rope slowly until you feel resistance, then pull quickly and smoothly with a full arm stroke.
- Allow the rope to rewind slowly. Repeat if necessary until the engine starts.
5.2 Stopping the Engine
To stop the engine, move the engine switch to the "OFF" position. Allow the engine to cool down before storage or further handling.
6. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your engine. Always ensure the engine is off and cool before performing any maintenance.
6.1 Engine Oil
- Check Oil Level: Check the oil level before each use.
- Change Oil: Change the engine oil after the first 5 hours of operation, then every 25-50 hours or annually, whichever comes first. Refer to the 'Specifications' section for oil type and capacity (0.5L).
6.2 Air Filter
The engine uses a sponge filter element. A dirty air filter will reduce engine performance and lifespan.
- Remove the air filter cover.
- Remove the sponge filter element.
- Clean the element with warm, soapy water, rinse thoroughly, and allow to air dry completely. Alternatively, replace with a new filter element.
- Reinstall the dry filter element and air filter cover.

6.3 Spark Plug
Inspect the spark plug annually or every 100 hours of operation. Clean or replace if necessary. Ensure the gap is set to the manufacturer's specification.
6.4 Fuel System
If storing the engine for an extended period (over 30 days), drain the fuel tank and carburetor, or use a fuel stabilizer to prevent fuel degradation.
