1. Introduction
This manual provides essential information for the safe and effective use of your Stanley FatMax 10m Construction Extension Cable. Please read these instructions carefully before use and retain them for future reference.
The Stanley FatMax extension cable is designed for demanding construction environments, offering reliable power extension with enhanced safety features. It features a 16A+T plug and socket with a protective cover, an IP44 rating for protection against solid objects and splashing water, and a robust HO7RN-F 3G1.5 mm2 cable for durability.
2. Safety Information
WARNING: Failure to follow these safety instructions may result in electric shock, fire, or serious injury.
- Always ensure the cable is fully uncoiled before use to prevent overheating.
- Do not exceed the maximum power rating of 3680 watts.
- Inspect the cable for any damage (cuts, abrasions, exposed wires) before each use. Do not use a damaged cable.
- Ensure the plug and socket connections are clean and dry before connecting.
- The IP44 rating protects against splashing water; however, do not immerse the cable or connections in water.
- Keep children and pets away from the extension cable during operation.
- Do not use the cable in hazardous environments without proper assessment.
- Disconnect from the power source when not in use.
- Always pull the plug, not the cable, when disconnecting.
3. Setup
- Uncoil the Cable: Carefully uncoil the entire 10-meter length of the extension cable. This prevents heat buildup that can occur when a coiled cable is under load.
- Inspect Connections: Check the male plug and female socket for any debris, moisture, or damage. Ensure the protective cover on the socket is intact and functional.
- Connect to Power Source: Insert the male plug (Type E) into a compatible 16A+T power outlet. Ensure a secure connection.
- Connect Device: Plug your electrical device into the female socket of the extension cable. Close the protective cover over the socket if it is not in use or to maintain IP44 rating during use.

4. Operating Instructions
- Power On: Once all connections are secure, activate the power source.
- Monitor Load: Ensure the total power consumption of devices connected to the extension cable does not exceed 3680 watts. Overloading can cause overheating and damage.
- Environmental Protection: The IP44 rating provides protection against splashing water and solid objects larger than 1mm. While suitable for outdoor use, avoid direct exposure to heavy rain or submersion.
- Cable Routing: Route the cable in a way that minimizes tripping hazards and protects it from damage by sharp objects, heavy machinery, or excessive foot traffic.

5. Maintenance
- Regular Inspection: Periodically inspect the entire length of the cable, including the plug and socket, for any signs of wear, cuts, cracks, or discoloration.
- Cleaning: Disconnect the cable from all power sources before cleaning. Wipe the cable and connectors with a dry or slightly damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: When not in use, coil the cable neatly and store it in a dry, cool place, away from direct sunlight and extreme temperatures. Avoid kinking or bending the cable sharply.
- Repair: Do not attempt to repair damaged cables or connectors yourself. Refer to qualified personnel for any repairs or replacements.
