What type of extension cord can I use with this lawnmower?

The extension cord must be suitable for outdoor use and have a current capacity rating sufficient to supply the product. The extension cord cable should be marked with either 'H05 RN-F' or 'H05 VV-F', and it must always be fully uncoiled during use as coiled cords can overheat. Damaged extension cords should not be repaired but replaced with an equivalent type. (Page 3)
