Troubleshooting
Impact wrench lacks power or torque
Check air pressure and flow from the compressor. Ensure the air hose is not kinked and is of the recommended diameter (10mm). Verify the air inlet fitting is clean and unobstructed. Ensure proper lubrication as per maintenance instructions.
Tool vibrates excessively
Confirm that the socket is properly seated on the anvil and fastener. Check for any damage to the socket or fastener. Excessive vibration can also indicate a need for internal lubrication or servicing.
Air leaks from the housing
Inspect the tool for any visible cracks or damage to the aluminium alloy housing. Check air line connections for tightness. Internal seals may require servicing if leaks persist.
Impact mechanism not engaging
Ensure the tool is set to the correct forward/reverse setting and trigger is fully depressed. If the impact mechanism is still not engaging, it may require professional servicing.
