Safety Information

Whilst ratchet wrenches present relatively low risk compared to other power tools, proper precautions ensure injury-free operation. Always wear appropriate safety glasses to protect against falling debris when working underneath vehicles or machinery. Ensure work areas remain adequately lit, supplementing with the tool's LED light where necessary to clearly identify correct fasteners and avoid slippage.

Before commencing work, verify that sockets attach securely to prevent detachment under load, which risks injury and fastener damage. Never exceed the tool's maximum torque rating, as this damages both fastener and tool whilst potentially causing sudden slippage. When working overhead, secure the tool with a wrist strap to prevent dropping, and maintain proper footing on stable platforms rather than overreaching from ladders or scaffolding.

For automotive applications, ensure vehicles remain properly supported on axle stands rather than relying solely on jacks, which can fail catastrophically. Battery maintenance proves crucial—only use manufacturer-approved chargers and inspect batteries regularly for damage, swelling, or corrosion. Tooled-Up stocks replacement batteries and chargers across all major platforms for maintaining safe operation. Consult HSE guidance on power tool safety for comprehensive workplace requirements, particularly when operating in commercial or industrial environments where additional regulations apply.
