Removing weeds
WARNING
Risk of burns! The spray bar must be in-
stalled in such a way that the outlet open-
ings face downwards.
Do not direct the water jet on persons or an-
imals.
Do not touch the WR 20/ WR 50 or hold the
water jet while the machine is running.
Set the device switch on the high-pres-
sure cleaner to max. 98 °C.
If installed, set the Servo Control to the
max. setting.
Switch on the high pressure cleaner
and pull the lever of the high pressure
gun.
Wait until hot water emerges from the
spray bar.
Note
Depending on the high-pressure cleaner in
use, the heating-up time can last between
2 and 5 minutes.
Guide the spray bar slowly over the
weed.
Repeat the procedure several times if
required.
Note
The optimal effect is achieved when hot
water escapes almost unpressurised with-
out any steam.
Shutting down
WARNING
Risk of burns! Allow the WR20 / WR 50 to
cool down before disassembly.
After the operation, operate the spray
bar with cold water for two minutes in
order to cool it down.
If necessary, rinse off the spray bar and
chassis and suspension (WR 50) with
clear water.
Protect the appliance against frost.
Clean the chassis and suspension (WR
50) of dirt, earth and plant residues
Regularly check the nozzles on the
spray bar for blockages.
Mind the weight of the appliance during
transport.
Consider the weight of the appliance
when storing it.
Store the appliance in a frost free area.
Troubleshooting
Steam is coming out of the spray bar:
Reduce the temperature setting on the
high-pressure cleaner.
The emerging water pressure is too
high:
Install the flow restrictor.
Select a suitable nozzle (see table).
High-pressure cleaner switches off/the
high-pressure cleaner burner does not
start:
Check the nozzles on the spray bar for
soiling.
Check the nozzles on the spray bar for
calcification.
The wheels of the chassis and suspen-
sion (WR 50) do not turn:
Check wheel axle and bearings for soil-
ing.
