eral factors:
–Proneness to blood circulation deficien-
cies (cold, numb fingers).
–Low ambient temperature. Wear warm
gloves to protect hands.
–A firm grip impedes blood circulation.
–Continuous operation is worse than an
operation interrupted by pauses.

Set dosing value for detergent to "0".
With open hand spray gun turn device
onandoffmultipletimes withthedevice
switch.
Open and close the pressure/quantity
regulation at the pump unit with the
hand spray gun open.
Note: By dismantling the high pressure
hosefromthehighpressureconnectionthe
venting process is accelerated.
If detergent tank is empty, refill.
Check connections and conduits.
–Pressure is set to MIN
Set pressure to MAX.
–Sieve in the water connection is dirty
Clean sieve.
Clean the fine filter; replace it, if necessary.
–Amount of water supply is too low.
Check water supply level (refer to tech-
nical data).
–Pump leaky
Note: 3 drops/minute are allowed.
With stronger leak, have device
checked by customer service.
–Leak in the high pressure system
Check high pressure system and con-
nections for tightness.
Leave device running with open deter-
gent dosage valve and closed water sup-
ply, until the swimmer tank is sucked
empty and the pressure falls to "0".
Open the water supply again.
If the pump still is not sucking in any deter-
gent, it could be because of the following
reasons:
–Filter in the detergent suck hose dirty
Clean filter.
–Backflow valve stuck
Removethe detergenthose andloosen
the backflow valve using a blunt object.
–System care container is empty.
Refill system care.
–Fuel tank empty.
Refill fuel.
–Water shortage
Check water supply, check connec-
tions.
Clean sieve in the water shortage safe
guard.
–Fuel filter dirty
Change fuel filter.
–No ignition spark
If device is in use and no ignition spark
can be seen through the viewing glas,
have device checked by customer ser-
vice.
–Working pressure/flow rate to high
Reduce working pressure/flow quantity
at the pressure/volume regulator in the
pump unit.
–Sooty heating spiral
Have device de-sooted by customer
service.
If malfunction can not be fixed, the de-
vice must be checked by customer ser-
vice.
