10.1

General servicing

Servicing of the unit should be carried out once annually by the
WAGNER service.
1. Check high-pressure hoses, device connecting line and plug
for damage.
2. Check the inlet valve, outlet valve and filter for wear.
10.2

High-pressure hose

Inspect the high-pressure hose visually for any notches or bulges, in
particular at the transition in the fittings. It must be possible to turn
the union nuts freely.
i
The risk of damage rises with the age of the high-
pressure hose. Wagner recommends replacing high-
pressure hoses after 6 years.
