Maintenance of Pneumatic Impact Wrenches

Pneumatic impact wrenches are power tools that do require regular maintenance. Poor lubrication is one of the most common causes of tool decay and failure. Here we will go through certain practices that can help you maintain your tools in better conditions.

Work area basics

Keep your work area clean and tidy. Cluttered and dirty work areas can cause you to lose valuable tools and materials.

Wear the right safety equipment: impact wrenches should be used only by those who have been properly trained, following all relevant health and safety policies.

Dress appropriately. Make sure everybody in the room is wearing eye protection. Never operate this tool where there are flammable liquids or gases near it because of potential explosion hazard concerns.

Air motor lubrication

We recommend running an inline, or manually applying some Air Tool Oil through the air intake before every use to prevent corrosion. 10-15 drops of oil into each inlet should do it! It’s also important that you take care of this otherwise your tool will become too dirty and stop working properly – so apply more after every few hours if necessary (or at least when using for extended periods).

Impact wrench correct lubrication procedure

Lubricating both the motor and impact mechanism is important for keeping your power tool running smoothly. Because the two systems are not linked, they must be lubricated separately.

A specific airline lubricator is used to lubricate the motor. You may either add it to the FRL or use it right away on the air intake (to tool). Depending on the system, the impact mechanism is lubricated. This mechanism can be either a grease impact mechanism or an oil bath one.

Grease impact mechanism

Only the contact areas between the anvil and hammer are lubricated in this system to minimize friction. Grease should be replenished regularly.

The grease, on the other hand, will flow from the touchpoints to the outside of the hammer over time on account of inertia. Because of this, there will be more friction and heat. If it isn’t maintained, it will eventually stop working. It needs to be serviced regularly.

Oil bath mechanism

The entire front portion of an impact wrench is immersed in oil in a tool with an oil bath system. Because it encompasses the entire system, the oil is always there. The gap is always lubricated, so there is less need for maintenance.

To change the oil, you have to open the wrench carefully. When you are done with the oil, then you need to dispose of it. Replace the old oil with new oil that is only suitable for impact systems, such as SAE30.

Which oil is used in air tools?

Mineral oil is made from petroleum and is colorless and odorless. It’s a by-product of the process that makes gasoline. It’s been used as an ingredient in lotions, creams, ointments, and cosmetics for a long time.

Mineral oil is a lubricant that’s good for pneumatic tools. A contractor’s framing gun is an example of a pneumatic tool with a few moving components.

The components of a pneumatic tool slide against each other without actually contacting each other. Between carefully designed pistons, valves, and cylinders, the parts form a waterproof seal. Rubber and nylon o-rings make up the airtight seal.

Because of the mineral oil, the air chambers will be free of dirt and sticky build-up. However, petroleum oils might leave behind remnants or build-up so you must not use them. Air tools work best with mineral oil that has anti-foaming and anti-gumming additives.

Disposing of oil appropriately

All need to be aware of the rules and regulations that govern oil disposal. Whether you are an individual, a small company, or a large corporation, it’s in everyone’s best interest to adhere to these standards.

Because of the Environmental and Planning Assessment (EPA)’s requirements, all oil and oil filters from equipment, vehicles, and other products must be disposed of or recycled in an environmentally responsible manner. According to the EPA, one oil change’s used oil may pollute 1 million gallons of water. The waste oil can be recycled or refined into lower grades of fuels.

It’s possible that you’ll need to store your used oil before disposing of it. Always follow the best practices when storing used oil. This will help keep your environment healthy and make it easier to handle.

Since oil is not hazardous waste, it does not need to be stored for a certain amount of time. This implies that you may hold off on transporting and recycling used oil until you have enough for reasonable transportation and recycling.

The best way to store used oil is safely and securely. Although there are many ways you can do this, one of the most important factors for safety would have to be proper signage on all containers as well as written procedures that outline when and how certain tasks should take place with your facility’s discards. 

Avoid mixing them up with other wastes by including appropriate warnings about what they contain. Putting these instructions into practice will help prevent accidents from happening during storage or transportation!

You may also have your used oil collected by a local body shop or service station, which will recycle the oil for you. It is not legal to dispose of used oil in your regular trash cans or toss it on the side of the road.

Disposing of oil filters correctly

Filters must also be disposed of correctly since, at the very least, trace amounts of used oil abound. You have three alternatives for recycling your used oil filters:

• puncture the air filter (remove the filter from the wrench, then pierce the end of it with a needle and put it upside down 12 hours, the oil will drain out into a pan and then recycle)
• remove the filter and crush it
• take your used oil filter to a body shop or a municipal recycling facility that accepts them

Conclusion

Pneumatic impact wrenches are a very useful tool to have in your impact wrench kit, but they do require regular maintenance. Poor lubrication is one of the most common causes of tool decay and failure. Following these simple guidelines, your wrench will be ready to use at a moment’s notice.
