1. Important Safety Instructions
Read all safety warnings and instructions before operating this tool. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury. Keep this manual for future reference.
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 such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Personal Safety: Always wear eye protection. Use appropriate personal protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection for relevant conditions. 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. It will do the job better and safer at the rate for which it was designed. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
Hedge Trimmer Specific Safety
- Keep Hands Away from Blades: Never attempt to remove cut material or hold material to be cut when blades are moving. Ensure the switch is off when clearing jammed material. A moment of inattention while operating the hedge trimmer may result in serious personal injury.
- Hold Tool Properly: Hold the hedge trimmer by insulated gripping surfaces only, because the cutter blade may contact hidden wiring or its own cord.
- Clear Work Area: Before starting, inspect the area for foreign objects such as wires or other debris that could become entangled in the blades.
- Maintain Balance: Always maintain proper footing and balance. Do not overreach.
- Use Shoulder Strap: Utilize the provided shoulder strap to reduce fatigue and maintain better control, especially when using the telescopic pole.
- Blade Cover: Always use the blade cover when storing or transporting the hedge trimmer.
