October 7, 2026 — A consumer reported suffering severe finger lacerations while handling a Ryobi RY40HG01 hedge trimmer, citing an unintentional start-up as the cause.

Product Details
Incident Overview
On September 21, 2026, a consumer reported a serious injury involving their Ryobi RY40HG01 hedge trimmer. The incident occurred while the individual was attempting to hang the tool on a wall hook for storage. During this routine action, the hedge trimmer reportedly started unintentionally, leading to immediate and severe trauma. The consumer sustained deep cuts to three fingers, necessitating urgent medical attention. The report explicitly states the user’s belief that these trimmers “need a safety switch to prevent unintentional starting,” suggesting a potential design flaw or inadequacy in the product’s existing safety mechanisms. The retailer where the product was purchased was not specified in the incident report.
Safety Concerns
This incident with the Ryobi RY40HG01 hedge trimmer raises significant safety concerns regarding the potential for unintentional activation, a risk that is critical for powerful cutting tools.
- Immediate Dangers: The most immediate and apparent danger is severe lacerations, punctures, or even partial or complete amputation of fingers or hands. Hedge trimmer blades move at high speeds, and accidental contact can result in devastating injuries requiring emergency medical care, including stitches, surgery, or specialized hand reconstruction. Significant blood loss is also a potential immediate threat.
- Long-Term Risks: Injuries sustained from hedge trimmer blades can lead to profound and lasting consequences. These may include permanent nerve damage, loss of sensation, chronic pain, reduced grip strength, limited range of motion, and impaired dexterity. Such long-term effects can severely impact an individual’s ability to perform daily tasks, engage in hobbies, and maintain employment, significantly diminishing their quality of life. The risk of infection in deep wounds is also a serious concern.
- Who Might Be Affected: Anyone handling the Ryobi RY40HG01 hedge trimmer is potentially at risk, particularly during periods of non-use such as storage, transport, cleaning, or maintenance. Even experienced users can be caught off guard by an unexpected start-up. The risk is magnified for individuals who may not strictly adhere to all safety protocols, or if the product’s design makes accidental activation too easy.
- Property Damage Potential: While the primary risk is personal injury, an unintentionally starting hedge trimmer could also cause damage to nearby objects, walls, or other equipment if it is dropped or if the blades strike something unexpectedly. If dropped while running, it could also cause further injury to feet or other body parts.
What Consumers Should Do
If you own a Ryobi RY40HG01 hedge trimmer or any similar power tool, it is crucial to prioritize safety to prevent such incidents.
- Immediate Steps After an Incident: If you or someone you know has been injured by a hedge trimmer, seek immediate medical attention for any wounds, no matter how minor they may seem. Document the incident thoroughly, including taking clear photographs of the injury, the product, and the surrounding circumstances. Preserve the product in its state at the time of the incident without attempting repairs.
- Check If You Own the Affected Product: Verify if you own the Ryobi RY40HG01 model hedge trimmer. This model number is usually found on a label affixed to the tool itself, often near the motor housing or handle.
- Prevention Measures:
- Remove Battery: For cordless models, always remove the battery pack from the hedge trimmer immediately after use and before performing any storage, cleaning, maintenance, or transport. Never handle or store the tool with the battery installed unless it is actively being used for trimming.
- Inspect Safety Features: Familiarize yourself with all safety switches and activation mechanisms on your hedge trimmer. Ensure they are functioning correctly and that the tool cannot be easily started accidentally.
- Proper Storage: Store hedge trimmers securely, preferably with blade covers in place, in a location where accidental contact with the trigger is unlikely and where children or unauthorized individuals cannot access them.
- Careful Handling: Always carry the hedge trimmer by its handle, keeping your fingers clear of the trigger and the cutting blades.
- Read the Manual: Always consult your product’s owner’s manual for specific safety instructions and guidelines provided by the manufacturer.
- Reporting Procedures: If you have experienced a similar incident, have concerns about the safety of your Ryobi RY40HG01 hedge trimmer, or believe it poses a risk, please report it to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. You should also contact One World Technologies, Inc., the manufacturer, directly to make them aware of the issue.
