Pneumatic tools common faults and solutions


Any tool will have a variety of faults after use, and our pneumatic tools are the same, because the working environment and working pressure in daily life lead to various failures of pneumatic tools. When you use the pneumatic tools, the following faults can be found. Please refer to the following solutions. Also, if there is no special tool, please do not disassemble it yourself. It should be returned to the dealer for processing; because the pneumatic tools are more precise. If it is forcibly removed, it may damage the parts inside, which will be difficult to repair.

First, the motor does not turn
Reasons: 1. The motor part is mixed with debris; 2. The bearing is damaged; 3. The main shaft is rusted and damaged; 4. The blade is worn; 5. The pressure is insufficient;
Solution: 1. Remove debris; 2. Change bearing; 3. Change spindle; 4. Change blade; 5. Check pipeline.
Second, cut off gas (only exhaust, no rotation, no blow)
Reasons: 1. Lack of butter; 2. Damage to parts of the striker; 3. Wear of the front cover; 4. Poor design;
Solution: 1. Change the butter; 2. Change the impact parts; 3. Change the front cover; 4. Change the new product.
Third, the spindle speed is slow
Reasons: 1. The air pressure is too low; 2. The position of the reverse lever or the speed lever is wrong; 3. The oil is not enough; 4. The fan blade and the cylinder cover are rusted and worn; 5. The lock nut is rusted;
Solution: 1. Adjust the air pressure; 2. Confirm the position; 3. Refueling; 4. Decompose and refurbish; 5. Separate and tighten.
Fourth, the strength of the strike department is insufficient
Reasons: 1. Wear parts of the striker; 2. Lack of butter; 3. Wear of the front cover;
Solution: 1. Change the impact parts; 2. Change the butter; 3. Change the front cover.
Five, the rotation does not stop
Reasons: 1. The switch valve has debris; 2. The spring is short-cut; 3. The switch valve is deformed;
Solution: 1. Remove debris; 2. Replace the spring; 3. Replace the switch valve.
Sixth, air leaks
Reasons: 1. Air inlet leakage; 2. Speed ​​control rod leakage; 3. On-off valve leakage; 4. Air outlet leakage;
Solution: 1. Replace the new head 2. Change the O-ring 3. Change the O-ring 4. Change the O-ring or clear the switch valve debris.
Special reminder: Some pneumatic tools may generate reaction torque during use, which makes the operator's body in a state of tension, affecting the balance of the body, and may pinch fingers. Therefore, special care should be taken when using multi-axis nut lock equipment, screwdrivers, ratchet wrenches, diagonal wrenches, rotors, tapping machines, pipe beveling machines, etc. Operators should be careful to take precautions against bad reaction torque.
If a fault occurs, it should be solved immediately. It must not be used any more. This will increase the degree of failure of the tool, resulting in difficulty in repairing or repairing. The care tool is everyone's responsibility!
