Setup
1. Fuel Mixture Preparation
The FX-MH123ECO uses a 2-stroke engine and requires a specific fuel mixture. Use unleaded gasoline mixed with high-quality 2-stroke engine oil at a ratio of 1:40 (1 part oil to 40 parts gasoline).
- Always mix fuel in a clean, approved fuel container.
- Shake the container well before filling the hedge trimmer's fuel tank.
- Do not store mixed fuel for extended periods.
2. Filling the Fuel Tank
- Ensure the engine is off and cool.
- Place the hedge trimmer on a flat, stable surface.
- Carefully open the fuel tank cap.
- Pour the prepared fuel mixture into the tank using a funnel to prevent spills. Do not overfill.
- Securely close the fuel tank cap. Wipe away any spilled fuel immediately.
Operating Instructions
1. Starting the Engine
- Place the hedge trimmer on a firm, flat surface. Ensure the blade is clear of any obstructions.
- Set the stop switch to the "ON" position.
- Engage the choke (if cold start).
- Press the primer bulb several times until fuel is visible.
- Pull the starter cord firmly and smoothly until the engine fires (usually 1-3 pulls).
- Once the engine fires, disengage the choke.
- Pull the starter cord again until the engine runs smoothly.
- Allow the engine to warm up for a few moments before engaging the throttle.
2. Cutting Operation
- Hold the hedge trimmer firmly with both hands.
- Maintain a stable stance and balance.
- Start cutting from the bottom of the hedge and work your way up for vertical cuts. For horizontal cuts, move the trimmer in a sweeping motion.
- Do not force the blade through thick branches. The maximum cutting capacity is 28 mm.
- Utilize the 90° pivoting rear handle for ergonomic cutting angles. Unlock, rotate, and lock the handle as needed.
3. Stopping the Engine
To stop the engine, simply move the stop switch to the "OFF" position. The centrifugal clutch will ensure the blades stop moving when the engine idles down.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your hedge trimmer.
1. Blade Maintenance
- Cleaning: After each use, clean the blades of sap, debris, and resin. Use a stiff brush and a suitable cleaning agent.
- Lubrication: Apply a light coat of machine oil or blade lubricant to the blades after cleaning to prevent rust and ensure smooth operation.
- Sharpening: If the blades become dull, they can be sharpened by a qualified technician or with appropriate sharpening tools. Always ensure the engine is off and the spark plug cap is removed before handling blades for sharpening.

2. Air Filter
Check and clean the air filter regularly, especially in dusty conditions. A clogged air filter can reduce engine performance and increase fuel consumption. Clean with warm soapy water, rinse, and allow to dry completely before reinstallation, or replace if heavily soiled.
3. Spark Plug
Inspect the spark plug periodically. Clean any carbon deposits and adjust the gap if necessary. Replace the spark plug if it is worn or damaged.
4. Storage
When storing the hedge trimmer for an extended period:
- Drain the fuel tank completely or run the engine until it runs out of fuel.
- Clean the entire unit thoroughly.
- Apply a rust preventative to the blades.
- Store in a dry, well-ventilated area, out of reach of children.
