Using the heavy duty electric wheelbarrow is easy. First, make sure the 36V 10.5Ah battery is fully charged. Then, use the Grin Technologies conversion kit to turn your regular wheelbarrow into an electric one. When loading, don't exceed the 100L capacity of the Kelso Heavy Trade Professional Wheelbarrow. While operating, be careful on uneven terrain to avoid tipping. After each use, clean the wheelbarrow and store it in a dry place. Charge the battery regularly, even if you don't use the wheelbarrow often, to keep it in good condition. If you notice any issues with the motor or battery, stop using it and contact a professional for repair.
