Important Safety Instructions

WARNING: Read all safety warnings and instructions before operating this product. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.

• General Safety: Keep work area clean and well lit. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Electrical Safety: Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Personal Safety: Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. It will do the job better and safer at the rate for which it was designed.
• Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• Service: Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• Blade Safety: Keep hands and feet away from cutting blades. Do not attempt to remove cut material or hold material to be cut when blades are moving. Ensure the switch is off when clearing jammed material.

3. While holding the safety lock button, squeeze the ON/OFF trigger switch (B). The blades will begin to move.

2. Stopping the Tool

To stop the tool, simply release the ON/OFF trigger switch (B). The blades will stop moving.

3. Using the Grass Shear Blade

The grass shear blade is ideal for trimming grass in areas inaccessible to a lawnmower, such as around flowerbeds, fences, or along edges.

• Hold the tool firmly with both hands if possible, or one hand if comfortable and safe.
• Keep the blade parallel to the ground or desired cutting surface.
• Move the tool slowly and steadily through the grass. Avoid forcing the blade through thick or wet grass.

4. Using the Hedge Trimmer Blade

The hedge trimmer blade is suitable for shaping and trimming small hedges, shrubs, and ornamental plants.

• Hold the tool firmly, ensuring a stable grip.
• Cut small amounts at a time. Do not attempt to cut branches thicker than 0.25 inches (6 mm).
• Move the tool in a sweeping motion, maintaining a consistent distance from the hedge for an even cut.
• For best results, trim the top of the hedge first, then the sides.

CAUTION: Always wear appropriate personal protective equipment, including safety glasses, gloves, and sturdy footwear, when operating the tool.

Maintenance

1. Cleaning

• Always ensure the tool is OFF and the battery is disconnected before cleaning.
• Clean the blades after each use. Remove any sap, debris, or grass clippings using a stiff brush or cloth.
• Wipe down the main body of the tool with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Ensure all parts are dry before storage.

2. Blade Care

• Regularly inspect blades for damage or dullness. Sharp blades ensure efficient cutting and reduce strain on the tool.
• Apply a light coat of machine oil or blade lubricant to the blades after cleaning to prevent rust and ensure smooth operation.
• If blades become dull, they can be sharpened by a qualified service technician or replaced.

3. Storage

• Store the tool in a dry, secure location, out of reach of children.
• Ensure the battery is fully charged before long-term storage to maintain battery health. Recharge every 3-6 months during extended storage.
