Why won’t my impact wrench remove lug nuts?

An impact wrench may not remove lug nuts for a couple reasons. First, check the regulator setting on the impact wrench and compressor and make sure each is set at 90-100 psi. If the regulators are set at the correct psi range, the next thing to do is check to make sure there is plenty of oil in the tool. If a tool is low on oil, it may not perform correctly.
