Safety Note: Wear safety glasses, ear protection, and gloves. Use only impact-rated sockets, never standard chrome sockets. Hold the tool firmly with both hands and keep clear of rotating parts. Do not over-tighten fasteners, and use a torque wrench for critical bolts such as wheel nuts. Unplug before changing sockets or accessories.
