3. Adding Engine Oil

The engine is shipped without oil. Fill the crankcase with the recommended type and amount of engine oil. Refer to the specifications section for oil type and capacity. Do not overfill.

4. Adding Fuel

Use fresh, clean, unleaded gasoline with an octane rating of 87 or higher. Do not use E85 fuel. Fill the fuel tank carefully, avoiding spills. Do not fill above the fuel filter screen.

5. Pre-Start Checks

Before each use, check the engine oil level, fuel level, and ensure all fasteners are tight. Inspect the air filter and clean if necessary.

Operating the Engine

1. Starting Procedure

1. Ensure the engine is on a level surface.
2. Open the fuel valve (if equipped).
3. Move the choke lever to the 'CHOKE' position (cold engine). For a warm engine, set to 'RUN'.
4. Move the throttle lever to the 'FAST' position.
5. Grasp the recoil starter handle firmly and pull slowly until resistance is felt, then pull quickly and smoothly to start the engine.
6. Once the engine starts, gradually move the choke lever to the 'RUN' position as the engine warms up.

2. Stopping Procedure

1. Move the throttle lever to the 'SLOW' or 'IDLE' position.
2. Turn the engine switch to the 'OFF' position.
3. Close the fuel valve (if equipped) for storage or extended periods of non-use.

Maintenance

Regular maintenance is crucial for the longevity and performance of your engine. Always perform maintenance with the engine off and cool, and disconnect the spark plug wire to prevent accidental starting.

• Oil Change: Change engine oil after the first 5 hours of operation, then every 50 hours or annually, whichever comes first.
• Air Filter: Inspect and clean the air filter every 25 hours or more frequently in dusty conditions. Replace if damaged.
• Spark Plug: Inspect the spark plug every 100 hours. Clean or replace as needed and ensure proper gap.
• Fuel System: Drain the fuel tank and carburetor if storing the engine for more than 30 days. Use a fuel stabilizer if draining is not possible.
• General Cleaning: Keep the engine clean from dirt and debris, especially around cooling fins and air intake areas.
