HANDLING THE HIGH-PRESSURE
HOSE
i
The unit is equipped with a high-pressure hose
specially suited for piston pumps.
Danger of injury through leaking high-pressure
hose. Replace any damaged high-pressure hose
immediately.
Never repair defective high-pressure hoses
yourself!
The high-pressure hose is to be handled with care. Avoid sharp
bends and folds: the smallest bending radius is about 8” (20 cm).
Do not drive over the high-pressure hose. Protect against sharp
objects and edges.
Never pull on the high-pressure hose to move the device.
Make sure that the high-pressure hose cannot twist. This can be
avoided by using a Wagner spray gun with a swivel joint and a
hose system.
i
When using the high-pressure hose while
working on scaffolding, it is best to always guide
the hose along the outside of the scaffolding.
i
The risk of damage rises with the age of the high-
pressure hose. Wagner recommends replacing
high-pressure hoses after 6 years.
i
Use only Wagner original-high-pressure hoses
in order to ensure functionality, safety and
durability.
