Maintenance
Storage/shipping
When preparing an FH Flyer head for storage or shipping, place dust caps over expander telescope and
focusing optics. Place a cap over Flyer’s Gas Purge port to prevent debris from entering the gas purge path.
If possible, repackage the head in its original SYNRAD shipping container to lessen the chance of damage.
Lens mount removal/replacement
For best results, remove the focusing lens assembly before cleaning. This allows you to work comfortably
and inspect the lens under good lighting.
The 80 mm, 125 mm, 125HP, and 200 mm FLA lenses used on FH Flyer marking heads are held in place
by three cap screws. Older FLA lenses, and all FLA 370 mm lenses, include a dowel pin that indexes the
lens to a specic orientation relative to the head.
To remove FH Flyer’s focusing lens for inspection and cleaning, perform the following steps:
1
Shut o and lock out all power to the laser and marking head. You must verify that the laser is OFF
before proceeding with lens removal and inspection!
2
While holding the one-piece lens mount assembly in place, remove the three 8–32 × 3/8" Allen cap
screws securing the focusing lens to the marking head (see Figure 7-1).

3
Carefully pull the lens mount away from the marking head and place it on a sheet of lens tissue for
inspection.
Important Note: Do not disassemble the lens assembly or attempt to remove the focusing lens from
its mount.
