10.10.1. Repairing of the air valve
Three levels
of maintenance are possible:
•
Level 1
: Standard level of maintenance since the air valve body is not subject to any fric-
tion or wear.
•
Level 2
: Corrective level, to be performed in case the valve body has deteriorated.
•
Level 3
: Exceptional level, to only be performed in case the magnet gets lost or broken.
Level 1: Replacement of the three O-ring
(P/N#
J3STKL032 interior O-ring, J3STKL005 exterior O-ring
and 900010256 conic sealant joint.
• For all three O-rings, extract the former one in
taking care not to damage the air valve
body (they may however be destroyed).
• The conic sealant joint must be pushed down
into its locking mechanism on the valve body
in being sure not to alter its conic range.
Level 2: If the air valve body (black part) has dete-
riorated.
• Manually extract or insert an M4 screw into
the aluminium ring (activating the locking
mechanism), pull along the axis of the part,
remove the magnet in paying attention to
identify its direction (silver-plated / black
sides).
• Raise the magnet in the right direction (
see §
10.10.1.1 page 37
) and lock the ring into the valve body by pushing firmly with your finger.
Once the gun has been completely reassembled, inspect the high-voltage activation and shut-
down. If the high-voltage is permanently activated or does not turn off: verify the magnet direc-
tion.
