6.4.5.1. Repairing the air valve
Three levels of maintenance are possible:
•
Level 1
: Standard level of maintenance because the body of the air valve does not undergo any friction
nor wear.
•
Level 2
: Corrective maintenance, carry out if the valve body is damaged.
•
Level 3
: Exceptional maintenance, carry out if the magnet is lost or broken.
Level 1
: Replacement of the three o-rings (P/N
J3STKL032 inner ring, J3STKL005 outer ring and
900010256 conical seal.
• For three seals, extract the old by taking care
of not damaging the body of the air valve (but
they can be destroyed).
• The conical seal must be pushed up to its click-
and-ratchet work on the body of the air valve
by taking care not to damage its conical reach.
Level 2
: If the valve body is damaged.
• Extract manually the aluminium ring or put a
M4 screw in the ring, pull out in the axle of the
part, and remove the magnet by taking care to
locate its direction (silver face on the ring side).
• Put in place the magnet in the right direction
and retain the ring in the body of the air valve
by pushing firmly with the finger.
After complete reassembly of the spray gun, check the activation and the stop of the high voltage. If the high
voltage is permanently engaged or does not cut itself: check the direction of the magnet.
Level 3
: If the magnet is broken or lost.
For this maintenance operation, it is recommended to contact Sames.
