An air tool that responds poorly when its trigger is pressed or released may have wear inside the throttle assembly. This replacement steel spring works with the throttle ball to support proper airflow control. Correct spring tension helps the throttle pieces move as designed, but the ball, seat, plunger, seals, and trigger should also be...Read more inspected. Clean the area and replace any damaged pieces found during service. Shut off the compressor supply, disconnect the air line, and press the trigger to release trapped pressure. Work over a clean surface so small pieces are not lost, and use the exploded parts diagram to confirm their order and direction.
A pneumatic hammer that runs poorly or responds unevenly may have damage inside its throttle system. This replacement ball works with the spring and seat to help control the compressed air entering the tool. Check the ball for wear, rust, dirt, or surface damage. Also inspect the seat, plunger, seals, and spring because replacing only one...Read more piece may not correct the problem. Shut off the air supply and disconnect the hose before service. Press the trigger to release trapped pressure and remove the working bit. Take apart the handle over a clean tray, keep the small pieces in order, and use the tool diagram during reassembly.
Proper airflow inside an air hammer depends on the throttle valve sealing correctly. A damaged or worn seat may cause air leaks, weak operation, or a trigger that responds poorly. Check nearby seals and valve parts before choosing a replacement. Match the seat to the full tool model and parts diagram. Shut off and disconnect the air hose,...Read more then release all stored pressure. Work over a clean surface so the ball and spring are not lost, and use only the approved lubricant during assembly.
