Air Tools / Pneumatic Tools use the compressed air supplied by the air compressor to drive the air motor to work. It can be used in the harsh environment of flammable, explosive, dusty, damp and shock. It is widely used in modern machinery manufacturing, ship building, automobile, airplane and so on. It does not pollute the environment, has long working life, simple structure and easy maintenance. Manufacturing, automotive repair, construction and decoration, metal / wood / stone processing, cutting, grinding, polishing, spraying, assembly, fastening and many other areas, is the modern mass production of large quantities of indispensable of the important tooling equipment.

1. Air Leakage

Possible Causes: Damaged air hose、Aged connections、Worn or damaged seals

2. Reduced Performance or Insufficient Power

Possible Causes:

Low air pressure、Blocked air lines、Worn parts、Insufficient lubrication、Obstructions

3. Screws or Bolts Not Tightening Properly

Possible Causes:

Incorrect tool selection、Low air pressure

4. Tool Self-Rotation or Abnormal Operation

Possible Causes:

Trigger switch jammed by debris

Aged or damaged seals

5. Worn Parts

Common Wear Items Include:
Gears, washers, blades, bearings、O-rings、shims、retaining rings、chucks、springs, etc.

6. Improper Maintenance

Possible Causes:

Using different lubricants for the motor and impact mechanism. Using incorrect oil may cause jamming or damage.

Follow the operation manual and use the correct lubricants.

7. Maintenance Recommendations

If the tool produces abnormal noise, air leakage, or insufficient power, check air pressure, fittings, air lines, and lubrication first.

For issues that cannot be resolved, seek professional repair services.

Avoid disassembling the tool yourself to prevent secondary damage or safety hazards.

1. Air tools in terms of working capacity and power tools compared to small and lightweight.

2. Air tools are more suitable for long hours of work, and there is no motor overheating can not work like.

3. Even if the pneumatic tool of the aerodynamic motor overload occurs like a phenomenon, but the lifting of the load can be restored to normal operation, unlike the electric motor will burn problems.

4. Pneumatic tools are not used for electricity, only with the pressure source, the water resistance is strong, no electric shock hazard, and because of no electricity, the tool itself does not produce sparks, can be applied to explosive environments (such as Kouang, ). In the case of environmental applicability, it is more suitable for all kinds of adverse environments than other tools, but maintenance work (such as water treatment, dust removal, refueling, etc.) must be done.

5. Air tools follow-up maintenance costs lower than the power tools.

6. Compared with the power tools, air tools, early investment is more than power tools (air compressors and air lines, etc.).

1. Air Tool Lubrication

Pneumatic tool oil provides cleaning, lubrication, and rust prevention. We recommend using clean, transparent SAE 10 pneumatic tool oil without sticky or viscous additives. Using unsuitable lubricants may cause internal motor components to seize.

Before and after daily use, inject approximately 2–3 cc of pneumatic tool oil directly into the air inlet. Then, operate the tool for a few seconds. For tools equipped with forward and reverse functions, operate the tool in both directions to allow the oil to circulate through the motor assembly and lubricate the internal components.

During prolonged operation, the lubrication frequency may be increased or decreased depending on the frequency of use and actual working conditions. Proper lubrication helps maintain smooth operation and reduce wear on internal components.

2. Grease Lubrication and Periodic Maintenance

It is recommended to inspect and replace the lubricating grease every 3 months. Apply an appropriate amount of grease and avoid overfilling, as excessive grease may increase operating resistance and reduce tool performance.

For models equipped with a grease filling port, remove the filling screw and apply a small amount of suitable lubricating grease every month. This helps maintain proper lubrication of the impact mechanism or clutch assembly, reduces component wear, and extends service life.

The actual maintenance procedure and grease type should be determined according to the tool model, internal structure, and product specifications.

3. Air Pressure and Compressed Air Quality

Higher air pressure may increase the output torque of pneumatic tools. However, operating the tool continuously at pressures exceeding its rated specifications may accelerate internal component wear and shorten its service life.

We recommend using clean, dry compressed air at an appropriate temperature and maintaining the correct operating air pressure according to the tool specifications to ensure stable performance and extend service life.

4. Air Line and Moisture Management

Pneumatic tools require clean and dry compressed air. Even if moisture and contaminants have been removed by the air compressor system, small amounts of moisture and impurities may still remain inside the air piping and hoses.

We recommend installing an FRL unit (Filter, Regulator, and Lubricator) in the compressed air supply system to improve air quality and provide proper lubrication.

In addition, regularly drain accumulated water and contaminants from the air compressor tank and air lines to prevent moisture from entering the tool and causing internal corrosion, wear, or component seizure.

5. Long-Term Storage and Rust Prevention

If the pneumatic tool will not be used for an extended period, we recommend injecting an appropriate amount of SAE 10 pneumatic tool oil into the air inlet before storage. Operate the tool for a few seconds to allow the oil to circulate throughout the motor assembly, then store the tool in a clean, dry environment.

If the tool has been stored for approximately 2–3 weeks, we recommend taking it out and lubricating it again to maintain proper lubrication and rust protection of the internal components.

Since compressed air may contain moisture, storing a pneumatic tool for an extended period without proper lubrication after use may allow residual moisture to cause internal components to rust or seize, potentially preventing the motor from operating properly.

Therefore, regular lubrication, proper maintenance before storage, and suitable storage conditions can help reduce the risk of malfunction and extend the service life of pneumatic tools.
