WARNING: Failure to replace the laser vacuum filters at the
appropriate intervals could create a hazardous operating environ-
ment.
WARNING: Hazardous materials. Wear safety goggles and dis-
posable protective gloves.
WARNING: Electric shock hazard. Shut down the PS288 (see
“Shut Down the System” on page 3-12) and turn off the main

1. Prepare the system—
1a) Verify that the PS288 is shut down and the main power switch is in the
OFF position.
1b) Remove the lower back laser housing panel.
1c) Loosen the vacuum hose clamp and detach the vacuum hose from the
extractor top.
1d) Undo the four spring clamps on the extractor top and remove the
extractor top.
2. Inspect the pre-filter—
If clogged or dirty, remove the filter and discard it in a sealable plastic
bag.
NOTE: For detailed instructions, see “Replace Pre-filter and
Pleated Filter in Fume Extractor” on page 5-18.
Clean the Laser Marker Shuttle Assembly
During extended or heavy periods of use, the shuttle assembly may become
dirty and gummed up by laser dust or other foreign material. This situation
may cause the shuttle assembly to stall during movement to and from the
laser mark position.
WARNING: Hazardous materials. Wear safety goggles and dis-
posable protective gloves.
WARNING: Electric shock hazard. Shut down the PS288 (see
“Shut Down the System” on page 3-12) and turn off the main
power switch. Do not use compressed air to remove laser dust.
To clean the laser marker shuttle assembly:
1. Prepare the system—
1a) Verify that the PS288 is shut down and the main power switch is in the
OFF position.
1b) Remove the upper left laser housing panel. Figure 5-5 shows the panel
removed.

2. Clean—
2a) Use a damp paper towel and antistatic cleaner to wipe laser marking
dust and other foreign material from the housing into a sealable plastic
bag.
2b) Place the paper towel in a sealable plastic bag. Pull off the disposable
protective gloves, place them in the sealable plastic bag, and close and
tightly seal the bag.
WARNING: Numerous government regulations apply to the stor-
age of hazardous waste. Ensure that contaminated filters are
properly labeled and stored in your hazardous waste storage area.
Also, make sure that they are not stored on your site longer than
government regulations allow (the typical limit is 90 days). Check
your government (local, state, and federal) regulations for haz-
ardous waste storage requirements.
2c) Clean the laser shuttle track using isopropyl alcohol.
3. Lubricate—
Use Tri-Flow lubricant to lubricate the bearing block and shuttle track.
NOTE: Use a small amount of lubricant, just enough to allow the
bearing block to move freely on the track. Too much lubricant will
aid in the build up of contamination and cause stalling.
4. Reinstall—
Reinstall all guards and panels.
