Helpful Tips:

1. If the Great Stuff Pro™ Dispensing Gun is used daily, it should be thoroughly purged weekly.
2. Close the flow control knob when not in use to prevent premature discharge.
   
3. Always leave a can of foam attached to the gun with the flow control screw closed. Use can within 30 days of initial use.
   
4. NEVER leave a gun without a can of adhesive without a can of Great Stuff Pro™ attached unless the gun has been thoroughly cleaned with Great Stuff™ Foam Cleaner.
