Remedy
Rinse the standard Vario nozzle (18)
with water. If required, clean the nozzle
bore hole with a needle (see chapter en-
titled cleaning).
Remove the nozzles (17/18) or the wash
brush (19) and ensure that the water can
discharge from the jet gun (1) unimped-
ed. In other words, the device is working
perfectly. The turbo dirt blaster (17) and
the rotating wash brush (18) do not nor-
mally get blocked.
Check ON / OFF switch (10)
Switch off the equipment and disconnect
from the mains. Check power supply
cable (6) for damage. If necessary have
the power supply cable (6) replaced by
a qualified electrician.
Check the electrical system for conform-
ity with the data on the rating plate.
Switch on the equipment with the jet gun
and with no nozzle until bubble-free wa-
ter comes out.
Check the water mains.
Switch off the equipment and disconnect
from the mains. Reconnect the equipment
to the water pipes (cf. "Initial Operation/
Set-Up")
Switch off the equipment and disconnect
from the mains. Replace the water con-
nection (9) inc. gasket (cf. "Spare Parts")
