Guidelines Guidelines

Guidelines

These recommendations are service level guidelines

- actual service levels required in your factory

will vary based on environmental and operating

conditions. High or low volume adhesive usage, as

well as adhesives that contain a powdered release

agent or are otherwise dusty, will have an impact

on the frequency of lter maintenance. To establish

a preventative maintenance cycle tailored to your

environment, Graco recommends inspecting lters

every 4 weeks after installation and replacing when

necessary. Document replacement intervals and

use this as your preventative maintenance schedule

moving forward.
