Usage Features:

The HYHT2600X is designed for user-friendly operation with several features to ensure efficient and safe use:

Starting and Stopping: The machine can be started using a recoil starter. It has a choke lever for cold starts and a primer bulb to facilitate fuel delivery. The ON/OFF switch controls engine operation, and the throttle trigger allows for variable speed control.
Throttle Lockout: This safety mechanism prevents accidental operation of the throttle control. It releases the throttle when the handle is grasped and automatically locks the throttle at idle when the handle is released.
Adjustable Rear Handle: The rear handle can be set in five different positions by pulling out a catch, allowing for ergonomic adjustments during various cutting angles. This adjustment should be made when the hedge trimmer is idling or not running.
Hand Guard: A protective hand guard is in place to prevent hands from coming into contact with the moving blades, especially if the operator loses grip.
Vibration Damping System: The machine incorporates a vibration damping system with rubber bushings to reduce the transfer of vibration from the engine and cutting equipment to the handle unit, enhancing user comfort and reducing fatigue.
Muffler: The muffler is designed to minimize noise levels and direct exhaust fumes away from the user. Some models may include a catalytic converter to reduce harmful exhaust gases.
Fuel Handling: The machine requires a specific petrol/oil mixture (40:1 ratio) and emphasizes careful handling of fuel due to its flammability. Refueling should be done in a well-ventilated area, away from open flames, and with the engine off and cooled.
Working Techniques: The manual advises working with a swinging action from bottom upwards for trimming sides, adjusting throttle to load, and keeping the engine facing away from the hedge. It also stresses using both hands and avoiding cutting overly thick material or hedges beyond normal reach.

Maintenance Features:

Regular maintenance is crucial for the HYHT2600X's performance and safety. The manual provides a comprehensive maintenance schedule:

Daily/Before Use Checks:
- Clean the outside of the machine.
- Verify correct function of throttle trigger lock and throttle.
- Clean muffler, exhaust pipe, and engine from dirt, leaves, and lubricant.
- Check stop switch functionality.
- Ensure blades do not move at idle.
- Inspect blades for damage (cracks, distortion) and replace if necessary.
- Check hand guard for damage and replace if necessary.
- Verify tightness of nuts and screws.
- Check for fuel leaks.
Every 25 Hours (or more often in dusty conditions):
- Clean and oil the air filter.
- Fill the gear housing with grease (do not overfill).
Every 40 Hours:
- Check starter and starter cord.
- Inspect vibration damping elements for damage.
- Clean spark plug, check electrode gap (0.5 mm), and replace if necessary.
- Clean the machine's cooling system (fins, cylinder cover, air intake).
- Clean the outside of the carburettor and surrounding area.
- Check and clean the spark arrestor mesh on the muffler (if fitted).
Every 100 Hours:
- Clean the inside of the fuel tank.
- Check the fuel filter and fuel hose for cracks or defects and replace if necessary.
- Check all cables and connections.
- Inspect clutch, clutch springs, and clutch drum for wear, replacing if necessary by an authorized service workshop.
- Replace the spark plug.
Blade Maintenance: Regularly check blade edges for damage, file away burrs, and ensure blades move freely. Tighten cutting unit screws to 7-10 Nm.
Storage: After use, allow the engine to cool completely before storage. Store in a cool, dry place away from ignition sources. Empty the fuel tank for long-term storage. Keep the engine and silencer free of debris, and spray cutting blades with light oil to prevent rust. The transport guard should always be fitted during transport or storage.

The manufacturer emphasizes using genuine spare parts and seeking professional service for complex repairs, especially concerning safety equipment. The manual also highlights environmental responsibility, advising proper recycling and disposal of waste materials and the machine itself.
