Troubleshooting
Press tool does not activate
Ensure the tool is fully charged (if applicable) and properly seated on the fitting. Check that the correct jaw size is being used.
Leak detected after pressing
While the leak-before-press system aims to prevent this, if a leak occurs, release the press, remove the fitting, inspect the pipe end and fitting for damage, and re-press with a new fitting if necessary. Ensure the pipe is clean and properly inserted.
Fitting appears loose after pressing
This may indicate an incomplete press. Release the tool and re-press, ensuring the tool is fully actuated according to its operating manual.
