4. Setup

4.1 Unpacking

Carefully remove all components from the packaging. Check for any damage during transit. Ensure all parts listed in the packing contents are present. Dispose of packaging materials responsibly.

4.2 Fuel Mixing

The MHT 2322 operates on a 2-stroke engine and requires a specific fuel mixture. Mix unleaded petrol with high-quality 2-stroke engine oil at a ratio of 50:1 (50 parts petrol to 1 part oil). Use a clean, approved fuel container for mixing. Shake the mixture thoroughly before pouring it into the fuel tank. Never use stale fuel or an incorrect mixture, as this can damage the engine and void the warranty.

4.3 Filling the Fuel Tank

Ensure the engine is off and cool before refueling. Open the fuel cap slowly to release any pressure. Fill the tank carefully, avoiding spills. Do not overfill. Securely close the fuel cap after filling.

5. Operating Instructions

5.1 Starting the Engine

1. Place the hedge trimmer on a flat, stable surface.
2. Press the primer bulb several times until fuel is visible in the bulb.
3. Move the choke lever to the 'CLOSED' position (cold start).
4. Pull the starter cord firmly and smoothly until the engine fires (usually 1-3 pulls).
5. Once the engine fires, move the choke lever to the 'OPEN' position.
6. Pull the starter cord again until the engine starts and runs smoothly.
7. Allow the engine to warm up for a few moments before beginning operation.

5.2 Holding the Trimmer

Hold the hedge trimmer firmly with both hands, ensuring a balanced grip. The MHT 2322 features a 180° rotatable handle with three grip positions, allowing you to adjust the handle for optimal comfort and control when trimming different sides of a hedge.

5.3 Trimming Techniques

• Top Trimming: Hold the trimmer with the blades angled slightly towards the hedge. Use a sweeping motion to cut across the top.
• Side Trimming: Hold the trimmer vertically. Use an upward sweeping motion for best results, allowing cuttings to fall away.
• Thick Branches: The 27 mm cutting capacity allows for cutting thicker branches. Do not force the blades through excessively thick material.
• Maintain a steady pace and avoid overreaching.

5.4 Stopping the Engine

To stop the engine, release the throttle trigger and move the engine stop switch to the 'OFF' position. Ensure the blades have come to a complete stop before setting the trimmer down.

6. Maintenance

Regular maintenance is crucial for the longevity and safe operation of your Mountfield MHT 2322 hedge trimmer. Always ensure the engine is off and cool, and the spark plug cap is disconnected before performing any maintenance.

6.1 Cleaning the Blades

After each use, clean the blades thoroughly to remove sap, debris, and dirt. Use a stiff brush and a suitable cleaning agent. Lubricate the blades with a light machine oil or blade lubricant to prevent rust and ensure smooth operation.

6.2 Air Filter

Check and clean the air filter regularly, especially in dusty conditions. A clogged air filter can reduce engine performance. Remove the filter cover, take out the filter element, and clean it with warm soapy water or compressed air. Ensure it is completely dry before reinstalling.

6.3 Spark Plug

Inspect the spark plug periodically. Clean any carbon deposits and check the electrode gap. Replace the spark plug if it is worn or damaged.

6.4 Fuel System

Inspect fuel lines for cracks or leaks. If storing the trimmer for an extended period, drain the fuel tank or use a fuel stabilizer to prevent fuel degradation.

6.5 Storage

Store the hedge trimmer in a clean, dry, and well-ventilated area, out of reach of children. Ensure the blade guard is in place. If storing for a long period, perform end-of-season maintenance as described above.
