How to clean or replace Dispenser Tubes on Mini-Roller^® HD.

Replace or Clean Dispenser Tubes 

To ensure proper fluid delivery, the dispenser tubes inside the rollers must be clean and free of debris. Inspect, clean, and replace components periodically as needed. The dispenser tubes should always be inspected when the roller covers are changed and serviced as needed. 

Visually inspect all holes in the dispenser tubes for debris or blockages. Use compressed air to blow out debris and ensure that air is coming out of every hole. If there are blocked holes, replace the dispenser tube.
