FAQ

Q1: My air impact wrench spins freely after releasing the trigger – is this normal?
Answer: Some free spin after releasing the trigger is normal due to residual inertia. However, if the wrench continues to spin excessively, it might indicate issues with the clutch or an internal part failing to disengage. Inspecting the internal mechanism is recommended in this case.

Q2: How can a worn-out hammer or anvil cause my air impact wrench to keep spinning?
Answer: The hammer and anvil are crucial in generating the impact force. When these parts wear out, they may fail to “catch” correctly, causing the tool to spin continuously without producing enough torque. Replacing these parts can often resolve the issue.

Q3: Could a blocked exhaust cause my air impact wrench to spin without torque?
Answer: Yes, a blocked exhaust can cause airflow issues, which may affect the tool’s torque and function. If the exhaust is blocked, clear it out and ensure smooth airflow through the tool to restore normal operation.
