The importance of having proper lubrication cannot be stressed enough. Without enough proper oil, you can easily shorten the life of a pneumatic tool and reduce the tools' efficiency in the work it should be capable of. Inadequate lubrication can be very evident when the tool is broken down for service and/or repair and would also normally void any warranty claims. 

There are several things to look for in setting up adequate tool lubrication:

• Some tools have an integral oil reservoir and oil metering system built in to the tool, which generally supplies a couple of hours of lubrication. This will need frequent checks and refilling because of their capacity (approx. 1 ½ ounces of oil). No adjustments to the oil supply are required by this system. 

• Line Oilers should be used, even if the tool has its own oil lubrication system. These oilers have the benefit of larger capacities, from 3 ounces to 16 ounces, so times between refills are longer. 

• Check to see if the correct line oiler is being used for the tool. There are two types, Pressure Feed and Constant Feed oilers. Constant Feed Oilers are typically used on tools that have long running cycles, such as Rock Drills. Because they run for extended period of time, they require lubricating constantly. Pressure Feed Oilers are used on all other ‘short cycling’ tools. 

• Line Oilers should be placed within 8 feet of the tool, any longer, the oil is ‘wasted’ by having to lubricate the hose before it reaches the tool. These oilers also have an adjustable oil flow, which will allow you to have a light or heavy oil mist being supplied to the tool. Care must be taken to avoid over-lubricating the tool as it may tend to make internal parts stick together, making the tool run erratic.

• Make sure the oiler is fitted correctly. There is an arrow on the side of the oiler indicating the direction of flow (towards the tool). 

• Make sure the correct type of oil is being used. Light oil is recommended for Paving Breakers, Chipping Hammers, Rivet Busters, Clay Diggers, Tampers and small Rock Drills (9 to 15lb class). This oil should be a 10W oil or ‘Air Tool’ specific oil widely available on the market. Air Tool oil typically contains additives that prevent rust and oxidation. For the heavier Rock Drills, Rock Drill specific oil should be used. This is heavier oil which contains rust inhibitors and has high lubricating properties, ideal for the more stressful situations found in heavy rock drilling operations.

Conclusion

In conclusion, maintaining proper lubrication is crucial for maximizing the lifespan and efficiency of your pneumatic tools. By choosing the right type of oil, using appropriate oilers, and ensuring correct placement and flow adjustments, you can prevent premature wear, avoid costly repairs, and keep your tools running smoothly. Regular lubrication checks and selecting oil types suited to specific tool demands will safeguard performance and protect your investment, ensuring your tools operate at their best for the long haul.
