TYPICAL WEAR PARTS
Despite the use of high-quality materials the highly abrasive
eff ect of the paints means that wear can occur at the following
parts:
Inlet valve (spare part Order No.: 0344700)
For replacing refer to Section 10.2
(failure becomes noticeable through performance loss and/or
poor or no suction)
Outlet valve (spare part Order No.: 0341702)
For replacing refer to Section 10.3
(failure becomes noticeable through performance loss and/
or poor suction) The outlet valve is usually considerably more
durable than the inlet valve. Thorough cleaning may already
help here.
Relief valve (spare part Order No.: 0169248)
For replacing refer to Section 10.5
(failure is noticeable through performance loss. Furthermore
material arrives constantly at the return hose although the
multifunction switch is set to spraying.
This part is relatively seldom a wear part.
