support ring (3) (clipped onto spring (2)), outlet valve seat
(5) and seal (6), refer to gure.
Please also pay particular attention to the following notes:
1. The torque for tting the outlet valve is 57-60 Nm.
2. During normal operation, check regularly whether the
outlet valve has become loose.
3. Always also replace the seal (6) if you have dismantled the
outlet valve, regardless of which component you want to

TYPICAL WEAR PARTS
Despite the use of high-quality materials the highly abrasive
e ect of the paints means that wear can occur at the follow-
ing parts:
Inlet valve (spare part Order No.: 2443943)
For replacing refer to Section 10.1
(failure becomes noticeable through performance loss and/or
poor or no suction)
Outlet valve (spare part Order No.: 2443904)
For replacing refer to Section 10.2
(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.
