Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury when operating power tools. Failure to follow these instructions may result in serious injury.

2.1 General Power Tool Safety

• Work Area Safety: Keep the work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Electrical Safety: Avoid body contact with earthed or grounded surfaces. Do not expose power tools to rain or wet conditions.
• Personal Safety: Always wear eye protection. Use appropriate personal protective equipment (PPE) such as hearing protection, non-skid safety shoes, and heavy-duty gloves. Stay alert, watch what you are doing, and use common sense when operating a power tool.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.

2.2 Specific Hedge Trimmer Safety

• Keep Hands Away: Never touch the blades while the tool is running. Keep all parts of the body away from the blade.
• Inspect Before Use: Before each use, inspect the hedge trimmer for damaged parts, loose fasteners, or any other condition that may affect its safe operation.
• Clear Obstructions: Before starting, ensure the area is clear of wires, fences, or other debris that could become entangled in the blades.
• Secure Grip: Always hold the hedge trimmer firmly with both hands during operation.
• Proper Stance: Maintain proper footing and balance at all times. Do not overreach.
• Blade Guard: Always use the blade guard when the tool is not in use or during transport.

4.2 Blade Guard

The blade guard is essential for safety. Always remove the blade guard before operation and re-install it immediately after use, before storage or transport. Ensure the blade guard is clean and free from damage.

5. Operating Instructions

Follow these steps for safe and effective operation of your hedge trimmer.

5.1 Starting and Stopping

1. To Start: Ensure both the front handle switch and the rear handle switch are depressed simultaneously. The tool will begin operation.
2. To Stop: Release either the front handle switch or the rear handle switch. The electric brake will quickly stop the blade.

The anti-restart function prevents the tool from starting if the battery is inserted while the switches are already depressed.

5.2 Cutting Techniques

• Hold Firmly: Always hold the hedge trimmer with both hands.
• Even Strokes: Use a smooth, sweeping motion to cut hedges. Avoid forcing the blade through thick branches.
• Branch Diameter: The tool is designed for branches up to 20mm in diameter. Do not attempt to cut larger branches, as this can damage the tool or cause injury.
• Working Height: Avoid working above shoulder height. Use a stable platform if necessary.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your hedge trimmer.

6.1 Cleaning

• After Each Use: Disconnect the battery. Use a stiff brush to remove leaves, twigs, and debris from the blades and housing.
• Wipe Down: Wipe the exterior of the tool with a clean, damp cloth. Do not use harsh chemicals or abrasive cleaners.

6.2 Blade Care

• Lubrication: After cleaning, apply a light machine oil or blade lubricant to the cutting blades to prevent rust and ensure smooth operation.
• Sharpening: If the blades become dull, they can be sharpened by a qualified service technician. Dull blades can cause the tool to bind and reduce cutting efficiency.
