PS288 Owner’s Manual 5—25

WARNING: Failure to replace the laser vacuum filters at the

appropriate intervals could create a hazardous operating environ-

ment.

WARNING: This procedure should be performed only by quali-

fied service personnel who have successfully completed

“Shut Down the System” on page 3-12) and turn off the main

power switch.

WARNING: Hazardous materials. Wear safety goggles and dis-

posable protective gloves. Do not clean the laser vacuum filters by

blowing with compressed air, shaking, or using any method that

allows the particulate trapped by the filters to be released into the

work environment.

1a) Verify that the PS288 is shut down and the main power switch is in the

OFF position.
