Safety instructions for using pneumatic tools

Pneumatic tools (such as pneumatic wrenches, air guns, grinders, etc.) are powered by compressed air and have high efficiency but high risks. To ensure homework safety, please strictly follow the following operating procedures:

1. Pre use inspection

✅  Tool inspection:

Check whether the trachea and joints are aging or broken to avoid air leakage or pipe bursting.

Confirm that the tool switch is flexible and there is no jamming or air leakage.

Check if safety accessories such as protective covers and mufflers are intact.

✅  Air source inspection:

The pressure of the air compressor should not exceed the rated working pressure of the tool (usually 6-8 bar).

Ensure that the air source is dry and prevent water vapor from entering the tool and causing internal corrosion.

✅  Personal protection:

Goggles (to prevent metal shavings and dust splashing).

Anti noise earplugs (pneumatic tool noise often exceeds 85 decibels).

Non slip gloves (to prevent tools from slipping off).

Safety shoes (anti smashing and anti puncture).

2. Operating standards

Correct installation:

When using quick change connectors, ensure that they are locked in place to prevent accidental detachment of the trachea.

When installing accessories such as grinding wheels and wire wheels, ensure that the rotation direction is consistent with the tool identification.

Homework requirements:

Maintain a stable posture: Hold the tool with both hands to avoid losing control when holding it with one hand.

Control air pressure: Do not use under overpressure to prevent tool overload and damage.

Prohibition of modification: Protective devices such as safety valves and speed controllers cannot be removed.

Dangerous prohibition:

❌  Do not aim pneumatic tools at yourself or others (even if not ventilated).

❌  Oxygen or other flammable gases should not be used as a substitute for compressed air.

❌  Smoking and open flames are strictly prohibited in the work area to prevent oil mist or dust explosions.

3. Maintenance and Storage

Daily maintenance:

After daily use, inject 3-5 drops of specialized lubricating oil for pneumatic tools through the air inlet.

Regularly clean the accumulated water and impurities inside the tool (especially in high humidity environments).

Storage requirements:

Disconnect the trachea, release residual air pressure before storing.

Place in a dry environment to prevent metal parts from rusting.

4. Common risks and countermeasures

Risk type prevention measures

Regularly replace aging trachea to avoid breakage or crushing due to tracheal rupture.

Tool loss of control ensures manual operation, and anti rebound devices are installed.

Before using the attachment, check whether the grinding wheel and saw blade are cracked.

Long term work with hearing loss requires wearing noise cancelling earmuffs.

5. Emergency situation handling

🆘  Tracheal rupture or leakage:

Immediately turn off the power of the air compressor.

Slowly release the residual pressure in the pipeline before replacing the trachea.

🆘  Tool stuck or overheated:

Stop the homework and disconnect the gas source.

After the tool cools down, check the cause of the malfunction and do not forcefully start it.

summarize

Check tools, gas source, and protection before use.

Stability: Standardized operation and prohibition of dangerous behavior.

Maintenance: Regular maintenance and safe storage.

Safety slogan:

Pressure is ruthless, and caution is necessary in operation - every step you take is a guarantee of life
