Troubleshooting Common Electric Impact Wrench Problems

Posted on: 16 May 2015

If there is one tool that you need to have in your garage as a mechanic, it is a heavy duty impact wrench. While the electric-powered impact wrench will likely give you years of service, it is not immune to its fair share of simple issues here and there. It would not be ideal to contact the manufacturer every time you have an issue, and therefore, it is a good idea to learn how to troubleshoot some of the most basic problems on your own. Here are a few of the most common problems and what you will need to do in order to fix them.

Problem: You are not getting enough torque with the impact.

Solution: If you have had your wrench on a shelf for a while and it has not been used, make sure you look at the wrench to check for signs of corrosion. Rust can prohibit the wrench from moving freely. Furthermore, you should make sure that the wrench motor is lubricated with a high-grade liquid lithium lubricant. If this is not your problem, readjust the regulator on the motor to it's maximum setting and try to run the wrench again. A higher speed setting will usually be enough to help the impact push through any compromises that may be present.

Problem: The wrench is leaking fluid around the impact head.

Solution: This is less an issue with the impact wrench itself and more of an issue with air lines or the air compressor tank itself. You should check the tank of your compressor and remove any moisture that is present and look over your lines to look for signs of leaks. There could also be problems with the air filter you are using to separate moisture in the compressed air.

Problem: The impact wrench runs slowly or will not power on at all.

Solution: This can be a sign that the motor or ball-bearing in the motor is starting to wear out, which will require a motor replacement. However, it can also be related to gunk built up in your wrench. Flush all of the debris out of your wrench by using a grease solvent or recommended solution.

In the end, if you cannot narrow down the problem on your own, it is always a good idea to find the manufacturer of your impact wrench and look for a troubleshooting guide on their website or give them a call. However, most heavy duty impact wrench owners find that knowing how to address simple issues saves them a lot more time when there is a problem.

Using Heavy Construction Equipment Safely

When I was a kid, my family owned a small timber company. My father, my grandfather, my three uncles, and my cousin worked hard to make this family business a success. Every year, they assessed their heavy equipment needs. If they discovered that they needed a new piece of heavy machinery, they did not hesitate to purchase it. They knew that replacing worn equipment was necessary in order to protect the employees of the business. Whenever they bought a new piece of machinery, they also scheduled training sessions to teach employees how to properly use it. On this blog, you will discover the importance of training employees how to safely use new heavy construction equipment.
