2. Safety Information
Always prioritize safety when operating and maintaining the engine. Failure to follow safety instructions can result in serious injury or property damage.
- Exhaust Fumes: Engine exhaust contains carbon monoxide, a colorless, odorless, and deadly gas. Operate the engine only in well-ventilated areas.
- Hot Surfaces: Engine components, especially the muffler, become very hot during operation and remain hot for a period after shutdown. Avoid contact to prevent burns.
- Moving Parts: Keep hands, feet, hair, and clothing away from moving parts such as the flywheel, fan, and recoil starter to prevent entanglement and injury.
- Fuel Handling: Gasoline is highly flammable. Store fuel in approved containers, in a well-ventilated area, away from ignition sources. Refuel outdoors with the engine off and cool. Do not smoke while refueling.
- Electrical Hazards: Do not touch spark plug wires or other electrical components while the engine is running or being started.
- Eye Protection: Always wear appropriate eye protection when working on or around the engine.
3. Setup and Installation
Proper setup is crucial for engine performance and longevity.
- Mounting: Securely mount the engine to a stable, level surface using appropriate hardware. Ensure adequate clearance for cooling and maintenance.
- Oil Fill: Before starting, fill the engine crankcase with the recommended type and amount of engine oil. Refer to the engine's oil capacity specifications. The engine is equipped with a low-oil sensor for protection.
- Fuel Fill: Fill the fuel tank with fresh, clean gasoline. Do not overfill. Ensure the fuel cap is securely tightened.
- Shaft Connection: The engine features a 1-inch diameter by 2.765-inch length shaft. Ensure proper alignment and secure connection to the driven equipment.

4. Operating Instructions
Follow these steps for starting and stopping the engine.
4.1 Starting the Engine
- Fuel Valve: Open the fuel valve (if equipped).
- Choke: Move the choke lever to the 'CHOKE' position for a cold engine. For a warm engine, the choke may not be necessary.
- Throttle: Move the throttle lever to the 'FAST' position.
- Recoil Starter: Grasp the recoil starter handle firmly and pull slowly until resistance is felt, then pull rapidly with a full arm stroke. Allow the rope to rewind slowly. Repeat until the engine starts.
- Choke Adjustment: As the engine warms up, gradually move the choke lever to the 'RUN' position.
4.2 Stopping the Engine
- Throttle: Move the throttle lever to the 'SLOW' or 'IDLE' position.
- Engine Stop Switch: Move the engine stop switch to the 'OFF' position.
- Fuel Valve: Close the fuel valve (if equipped) for storage or extended periods of non-use.
5. Maintenance
Regular maintenance ensures optimal performance and extends engine life.
- Check Engine Oil: Check the engine oil level before each use. Add oil as needed to the full mark.
- Change Engine Oil: Change the engine oil after the first 5 hours of operation, then every 50 hours or annually, whichever comes first.
- Air Filter: Inspect the dual clean air filtration system regularly. Clean or replace the air filter elements as necessary, especially in dusty conditions.
- Spark Plug: Inspect and clean the spark plug annually or every 100 hours. Replace if electrodes are worn or pitted. Ensure correct gap.
