Historically, impact wrenches were predominantly pneumatic, or air powered, which left them squarely in the domain of professional mechanics. To run a typical 1⁄2-inch pneumatic impact wrench, you usually need an air compressor putting out close to 100 psi—a significant investment. These tools have two important mechanisms, the “air motor” and the impact mechanism. Unlike their cordless counterparts, these parts are lubricated separately. Following are some of the problems with impact wrenches and their repair solutions. Impact Wrench Not Producing Enough Torque Apply multi-purpose grease to the anvil, the ball bearing between the anvil and the spindle, the planetary gears, the main gears (located inside the hammer case), and the inside of the hammer case as well.

All things being equal, higher voltage will give you more power—but there are cases for lower voltage. With smaller batteries, 12-volt impact wrenches are more compact. This makes them good for smaller jobs, working overhead, or getting into tight spaces. Tools with 18 and 20 volts have less difference between them. Generally, 18-volt tools with advanced features and capabilities make them more versatile and easier to use.Amp hours (Ah) equals the number of amps that the battery will discharge, continuously, for an hour. Think of amp hours like the volume of a gas tank—a bigger number equals more gas. IPM vs. RPM Impact wrenches have many moving parts that need attention so that you can make the most of your tool. Here are some tips for the maintenance and care of your impact wrench: 1. Lubricate Regularly

Power wrenches are perfect tools for handling bolted connections, metalware or furniture assembly as well as for car servicing where torque tools are must-have. So, we will analyse the main aspects that will help you choose a proper impact wrench suitable for your needs. To reoil your machine, remove the oil filler’s plug, drain the old oil, and fill it with new oil through the filler plug. Some models require removing the hammer case to drain the old oil. It can be a messy process, so be careful. The Makita DTW190Z is not an exception to the above-mentioned rule. It stands out for a great combo of cordless design and decent power characteristics offered at a budget-friendly price. Fitted with the Makita brushless motor, this impact wrench delivers a rather high impact rate of up to 3000 IPM that will let you easily remove stubborn bolts and nuts. With a maximum rotation speed of 2300 RPM and a fastening torque of 190 Nm, the tool will come in handy for a variety of household needs. The speed is variable and controlled by a special trigger located on the handle. Meanwhile, by choosing a forward or reverse driving shank rotation you can either tighten or remove the fasteners. Electric Motor Problems (Brushed): If your tool is not brushless, the motor brushes may be worn and need to be replaced. This is one of the most common reasons for the failure of brushed machines. High torque impact wrench battery leverages existing IQV®20 battery platform with enough power for a full day of workIf you are using your tool all day, every day, you should consider installing an inline lubricator. Lubricating the Hammer Mechanism:

Extreme weather conditions can strain any tool, and impact wrenches are no exception. Anvils are strong but can weaken when subjected to sudden temperature changes or extremely hot or cold weather. Have you noticed grease coming out from the front of your tool? If so, that grease has to be replenished at some point. Unlike cordless drill/drivers and impact drivers, which excel at drilling holes and driving screws, the impact wrench is specially designed for tightening and loosening various hex-head bolts, nuts, and lag screws. It employs both rotational force (torque) and short-burst concussive blows (impacts) to deliver an unparalleled amount of power. For example, most cordless drill/drivers produce about 50 foot-pounds of torque, and the average impact driver delivers about 125 foot-pounds. By comparison, cordless impact wrenches can easily produce torque outputs of over 250 foot-pounds, which is more than enough muscle to power-drive the fattest lags and bust loose rusty, corroded nuts.

Cordless impact wrenches need less attention than their pneumatic counterparts; however, although they seem to be maintenance-free, this isn’t always the case. Mechanical Problems: poor lubrication can turn the tool’s moving parts harder to move, which may result in poor torque output.
