INTENDED USE
Before starting the machine, it is necessary to know how to quickly stop it and understand the correct use of
all the commands and to know the security instructions.
Don’t allow someone to use the machine before having carefully read the instructions.
This machine has to be use only by trained people that are also aware of the security rules.
Use the machine just to remove the weed (steam weeding version) or to the high pressure washing
(high pressure washing function) or as a sprayer
The water in the tank is sucked and sent under pressure by a pump driven by a gasoline generator and sent
to a boiler or burner powered by car diesel fuel that warms the water to the desired temperature: steam at
120-140 °C for weeding mode, water at 80 °C maximum for the washing mode. The action on the two
lances operates the burner warming the water up at the chosen temperature. When the burner is off the
water goes out at the outside temperature.
Don’t use the machine with flammable liquids, corrosive acids or any other product that doesn’t refer
to the treatment, use only clean water.
These instructions are integral parts of the machine and they have to be delivered with the machine
when it is sold or rented.

Follow one of the two procedures shows below to do the weeding or the washing:
WEEDING MODE PROCEDURE
To obtain the best weeding results you have to work with one or two weeding shields at the same
time (one for each lance) or with a 40 cm boom on only one lance. The use with a weeding shield on
a lance and the boom on the other lance doesn’t allow to reach the maximum temperature of work.
1. Connect the accessory desired (weeding shield or 4 nozzles boom) to the lance with the quick connector
Always check the nozzles are clean and not clogged.
Caution: hot parts. Danger of burn.
2. Adjust the pressure gauge to 20 bar with the pressure regulator’s knob.
Caution: it is dangerous to work at a pressure of more than 20 bar if the temperature of the
boiler exceeds 80 °C. Risk of damaging of the boiler.
3. To adjust the working temperature desired push and release the button on the thermostat
(pos. 5)
The red display shows "Set 1"
use the key to increase the temperature (always 140°C MAX).
use the key to reduce the temperature (always 40° C MIN).
After 10 seconds the new value will be stored in the green display
The red display will show the current value.
The temperature suggested for a good weeding result is 120-140° C.
4. To increase the water temperature till 140° C let it circulate by pushing the lever gun:
- of the 2 lances if they works at the same time
- of one lance if only one person works.
5. Check the temperature in the red display of the thermostat (Pos. 5).
When the water temperature shown on the thermostat (pos. 5) exceeds 120° C you can start the
weeding treatment.
TO REDUCE THE CONSUMPTION OF FUELS YOU CAN WORK AT A TEMPERATURE OF120°C AND
THE GENERATOR IN ECONOMIC MODE AUTO P-SAVE
Avoid to pass on the grass you don’t want to remove with water warmer than 70° C.
NOTE:
The burner automatically stops warming when the lever of the gun is released or when the temperature
reaches about 140°C (temperature alarm on) and it starts again operating when the lever is push again or
when the temperature drops below 130°C
