1. Introduction and Product Overview
The Loncin LC1P70FC gasoline engine is a reliable, modern, versatile, and ergonomic unit designed with a vertical shaft. This 4-stroke OHV (Overhead Valve) engine features a single cylinder and is engineered for durability and efficient performance. Its construction includes a cast iron alloy sleeve to extend service life. Air cooling is effectively managed through cooling fins that draw airflow through the hand starter's openings, maintaining optimal operating temperatures.
With a displacement of 196 cubic centimeters, the engine delivers a maximum power output of 6.5 HP at a crankshaft speed of up to 3600 rpm. The 1-liter fuel tank allows for extended operation under various loads. The replaceable air filter with double cleaning ensures consistent and stable temperature regulation. The LC1P70FC also incorporates advanced automatic features such as speed control for stable performance. The standardized crankshaft has a diameter of 22.2 mm and a usable length of 80 mm, with rotation occurring counter-clockwise when viewed from the shaft side.
Key Features:
- Reliable 4-stroke engine with 6.5 HP power.
- Vertical shaft configuration for diverse applications.
- Double cleaning air filter for enhanced engine protection.
- Easy start system for quick and convenient operation.
- Low smoke and noise levels for a more pleasant user experience.

- Fuel Safety: Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the engine or fuel. Store fuel in approved containers.
- Exhaust Fumes: Engine exhaust contains carbon monoxide, a colorless, odorless, poisonous gas. Operate the engine only in well-ventilated outdoor areas. Never operate indoors.
- Hot Surfaces: The engine and muffler become very hot during operation and remain hot for a period after shutdown. Avoid contact to prevent burns.
- Moving Parts: Keep hands, feet, and clothing away from moving parts such as the flywheel and crankshaft.
- Eye Protection: Always wear appropriate eye protection when operating or servicing the engine.
- Electrical Safety: Do not touch spark plug wires or other electrical components while the engine is running.
- Children and Pets: Keep children and pets away from the engine, especially during operation.

4. Setup and Initial Preparation
Before starting the engine for the first time, proper setup and preparation are essential to ensure safe and efficient operation.
4.1. Add Engine Oil
IMPORTANT: The engine is shipped without oil. Failure to add oil before starting will cause severe engine damage and void the warranty. Refer to Figure 3.3 for the oil warning tag.
- Place the engine on a level surface.
- Locate the oil fill cap/dipstick (typically near the bottom of the engine, as indicated by the warning tag).
- Remove the oil fill cap/dipstick.
- Add approximately 0.5 liters of recommended 4-stroke engine oil (e.g., SAE 10W-30) into the oil fill opening. Fill until the oil level reaches the upper mark on the dipstick or the edge of the fill opening. Do not overfill.
- Securely replace the oil fill cap/dipstick.
4.2. Add Fuel
Use fresh, unleaded gasoline with an octane rating of 87 or higher. Do not use E85 or gasoline containing more than 10% ethanol.
- Ensure the engine is off and cool.
- Locate the fuel tank cap (refer to Figure 3.2).
- Unscrew the fuel tank cap.
- Carefully pour up to 1 liter of gasoline into the fuel tank. Do not overfill. Leave some space for fuel expansion.
- Securely replace the fuel tank cap. Wipe up any spilled fuel immediately.
4.3. Mounting the Engine
Mount the engine securely to the equipment it will power using appropriate bolts and fasteners. Ensure the mounting surface is stable and capable of supporting the engine's weight and vibrations during operation. Refer to the technical drawings for mounting dimensions.
5. Operating Instructions
5.1. Starting the Engine
- Ensure the engine has sufficient oil and fuel.
- Open the fuel valve (if equipped).
- Move the choke lever to the 'CHOKE' position (for cold starts). For warm starts, the choke may not be necessary.
- Move the throttle lever to the 'FAST' or 'START' position.
- Grasp the recoil starter handle firmly. Pull slowly until resistance is felt, then pull quickly and smoothly to start the engine. Do not let the rope snap back; guide it gently.
- Once the engine starts, gradually move the choke lever to the 'RUN' position as the engine warms up.
- Adjust the throttle to the desired operating speed.
5.2. Stopping the Engine
- Move the throttle lever to the 'SLOW' or 'IDLE' position.
- Move the engine switch or stop lever to the 'OFF' or 'STOP' position.
- Close the fuel valve (if equipped) for storage or extended periods of non-use.
6. Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your Loncin LC1P70FC engine. Always perform maintenance with the engine off and cool, and disconnect the spark plug cap to prevent accidental starting.
6.1. Engine Oil Change
Change the engine oil after the first 5 hours of operation, and then every 25-50 hours or annually, whichever comes first.
- Run the engine for a few minutes to warm the oil, then shut it off.
- Place a suitable container under the oil drain plug.
- Remove the oil fill cap/dipstick and the oil drain plug. Allow the oil to drain completely.
- Reinstall the oil drain plug and tighten it securely.
- Refill with approximately 0.5 liters of recommended 4-stroke engine oil (e.g., SAE 10W-30). Check the level with the dipstick.
- Replace the oil fill cap/dipstick.
6.2. Air Filter Maintenance
The engine features a double cleaning air filter (refer to Figure 3.4). Inspect and clean the air filter every 25 hours or more frequently in dusty conditions.
- Remove the air filter cover.
- Carefully remove the foam and paper filter elements.
- Clean the foam element by washing it in warm, soapy water, rinsing thoroughly, and allowing it to air dry completely. Lightly oil the foam element with engine oil and squeeze out excess.
- Clean the paper element by tapping it gently against a hard surface to remove loose dirt. Do not wash or use compressed air on the paper element. Replace if heavily soiled or damaged.
- Reinstall the filter elements and the air filter cover.
6.3. Spark Plug Inspection
Inspect the spark plug every 50 hours or annually. Replace if necessary.
- Remove the spark plug cap.
- Use a spark plug wrench to remove the spark plug.
- Check for carbon deposits, electrode wear, and proper gap. Clean deposits with a wire brush. Adjust the gap if needed (refer to specifications for correct gap).
- Reinstall the spark plug and tighten it to the specified torque. Reattach the spark plug cap.
