Questions and answers
Why won't work under fitting pressure
The Central Pneumatic part number 68293 may not work under fitting pressure due to several possible issues:
1. Not enough air pressure or air flow – the air supply may not be providing sufficient CFM at the required PSI.
2. Obstructed trigger – debris or buildup may prevent proper trigger movement.
3. Incorrect or insufficient lubrication – lack of proper air tool oil or grease can reduce performance.
4. Blocked air inlet screen – buildup may restrict airflow.
5. Air leaking from loose housing – leaks can reduce pressure and tool efficiency.
