Setup
1. Handlebar Assembly
- Attach the handlebar assembly to the main shaft using the provided clamps and bolts. Ensure it is securely fastened and positioned for comfortable operation.
- Connect the throttle cable from the engine unit to the throttle lever on the handlebar.
2. Attaching the Desired Head
The GX50 system allows for quick interchangeability of various heads. For example, to attach the string trimmer head:
- Align the attachment shaft with the main shaft coupling.
- Insert the attachment shaft into the coupling until it clicks into place or the locking pin engages.
- Secure the attachment with the locking knob or bolt, ensuring there is no wobble.

3. Fueling the Engine
- Ensure the engine is off and cool.
- Use fresh, unleaded gasoline with an octane rating of 87 or higher. This is a 4-stroke engine, so no oil mixing is required for the fuel.
- Carefully remove the fuel cap and fill the fuel tank (capacity: 1000ml) to approximately 90% capacity to allow for expansion.
- Securely replace the fuel cap. Wipe up any spilled fuel immediately.
Operating Instructions
Starting the Engine (Smart Starting Technology)
- Place the trimmer on a flat, stable surface.
- Ensure the ON/OFF switch is in the "ON" position.
- If the engine is cold, move the choke lever to the "CLOSED" or "START" position. If warm, leave it in the "OPEN" or "RUN" position.
- Press the primer bulb several times until fuel is visible in the clear return line.
- Pull the starter rope with a smooth, steady motion until the engine fires (usually 1-3 pulls). Do not pull the rope to its full extension or let it snap back.
- Once the engine fires, move the choke lever to the "OPEN" or "RUN" position.
- Allow the engine to warm up for a few moments before engaging the throttle.
Using the Trimmer
- Adjust the shoulder strap for comfortable balance and control.
- Maintain a firm grip on the handlebars.
- Keep the cutting attachment away from your body and obstacles.
- For string trimming, use a sweeping motion, cutting from right to left for optimal debris deflection.
- The trimmer offers a reach of up to 68 inches, allowing access to high or difficult-to-reach areas without ladders.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your equipment.
After Each Use:
- Clean the exterior of the engine and attachments. Remove grass, dirt, and debris.
- Inspect the cutting line/blade for wear or damage. Replace as needed.
- Check for loose fasteners and tighten if necessary.
Periodically:
- Air Filter: Clean or replace the air filter. A dirty air filter can reduce engine performance.
- Spark Plug: Inspect and clean the spark plug. Replace if worn or fouled.
- Fuel Filter: Check and replace the fuel filter if clogged.
- Gearbox Lubrication: Refer to the specific attachment manual for lubrication requirements of gearboxes (e.g., chainsaw head).
Storage:
- For long-term storage, drain the fuel tank or use a fuel stabilizer. Run the engine until it stops to clear the carburetor of fuel.
- Clean the entire unit thoroughly.
- Store in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.
