Why You Must Lubricate Impact Wrenches
If you try to remove a nut and you find that it is firmly in place, you may need to use an impact wrench instead. This device generates force necessary to dislodge most nuts. However, if you want to get the maximum life out of your impact wrench, you will want to make sure that it is properly lubricated.
Fortunately, you can usually lubricate the impact wrench with light motor oil, but check your owner's manual to make sure.
Understanding Why You Must Lubricate
Lubrication is essential because an impact wrench can be ruined by the buildup of debris and water contamination. Lubrication also makes the impact wrench more efficient. Because of anti-corrosive agents, the lubricant is often all you need to prevent corrosion.
Impact wrenches need to be lubricated or they will not last as long. The wrench needs to be lubricated before it is used for the first time. It must be lubricated after each use and it should be lubricated before each subsequent use. Therefore, you must make sure that you have enough lubricant on hand at all times.
Identifying Where to Lubricate the Motor
The impact wrench must be lubricated in the air motor and the impact mechanism. Also, the owner's manual might instruct you to lubricate other parts of the impact wrench. For example, most air tools will have several grease fittings that you will need to lubricate.
Lubricating the Motor
To begin lubricating the motor, you will need to disconnect the air hose from the wrench. Push the collar that fits the air hose from the tool. Then, you should hold the tool that has the inlet, found near the bottom of the hand grip, squeeze the trigger and hold it. While doing this, add the motor oil to the inlet hole. Then, you can let go of the trigger. After lubricating, oil discharges from the exhaust port for a few seconds. You will want to cover the exhaust port with a towel to prevent a mess.
Lubricating the Impact
Aluminum-bodied impact mechanisms have a pressure feed mechanism found at the back of the tool. The system takes the oil from a reservoir and feeds it to a crankcase so that the mechanism can then be internally lubricated.
Your impact wrench is likely an essential tool for your business, so the last thing you want is for it to fail. While keeping it lubricated might seem like a hassle, it is better than having your impact wrench fail.
