If leakage occurs, inspect the chuck and o-ring for defects. If the chuck is
damaged it is recommended that it is replaced with a new Laurell chuck. If the
chuck is defect free, wipe the chuck and o-ring surface with IPA. The cleaning
solution or solvent must be compatible with the o-ring material. Repeat wet test.
If wiping down the chuck and o-ring fails to prevent leakage remove and clean
the o-ring. See section 4.1.4.

4.1.4 CLEANING AND REPLACING THE CHUCK O-RING
•
To remove the o-ring from the chuck, insert a thin blunt instrument or o-ring puller
into the o-ring groove and pull upward. Be careful not to damage the o-ring or
chuck. Inspect the o-ring carefully. If the o-ring is cut, nicked or scratched it must
be replaced. Contact Laurell for part number and ordering information. If the o-
ring is in good condition, wipe it with a cleaner and insert it back into the o-ring
groove. Use the following procedure to insert the o-ring.
1 - Carefully press the
o-ring into the chuck
face groove. Do so by
pressing in a small
section at a time.
2 - After the
small sections
have been
pressed in,
carefully press
around the
chuck until the
o-ring is fully
seated.
3 - The o-ring should
lay flat in the groove.
4 - There should
not be any areas
that do not lay flat.
If this occurs,
continue to press
around the chuck
until they are gone.
