6.4.6.1. 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 (
A
), J3STKL005 outer ring (
B
)
and 900010256 conical seal (
C
).
• 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 (
D
) 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 (
E
) 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.
