BRUSHES

These brushes must be
connected to the STEAM
LANCE. They are used to
remove resistant dirt and for
deep cleaning, even in the
corners or small spaces.
Choose the most suitable type
(ø28, 40, 60 mm) according to
the surface to be treated.

MANTAINANCE

(End user)

Always remove the plug before cleaning

or carrying out operations on the machine.
* End user must not open or dismantle the
machine

For the safety of the operator and to always ensure a
perfect performance, we recommend the following
checks and maintenance:

AFTER EVERY USE:

For a correct cleaning, it is advice to clean the machine
and  its  accessories  with  a  clean  cloth  moistened  only
with  a  few  drops  of  water.  Do  not  use  alcohol  or  other
solvents,  they  may  damage  the  plastics  and
components.
To maintain efficient and easy to couple the accessories,
check  the  o-ring  seal  (

steam sealing gaskets

) and

possibly wet them with a little silicone grease.
VACUUM FUNCTION: when you finish to vacuum, it is
advisable to vacuum some water to clean the conducts
and the filter. Afterwards, dry the bucket or do not totally
close it so that it will dry itself.

PERIODICALLY:

Periodically check that the power cord does not show
signs of wear or aging. If it is damaged, it is absolutely
necessary to get it replaced by specialized personnel
before being able to re-use the appliance again.

BOILER CLEANING

(End user)

Once a year a check and boiler cleaning must be carried
out in our authorized centers.

RINSE

: It’s recommended at least every 50 hours of

operation or 2 months.
a) DISCHARGE: The machine must be cold or definitely
discharged from the steam pressure and the plug
disconnected. With the help of a wrench CH 21 unscrew
the

cap

(15)

placed

under

the

correspondence  of  the  boiler (see  image).  After  having
taken  off  the  cap,  shake  slightly  the  machine  to  let  the
water and the dissolved limestone out.
When the boiler is empty, clean and close carefully the
cap tightening it with the wrench.
b) FILLING: Fill the water tank (7), turn the machine on
and  make  it  start  again,  waiting  for  the  boiler  to  be  re-
charged again.
(

att

: it may be that during the first charge cycle, th

e “end

the machine to complete the load)

BOILER AND TANK CLEANING:

The boiler cleaning is recommended at least every 200
hours of operation or 6 months.
1- Cleaning with suction of the plastic tank (7): Check
that the water level in the plastic water tank (7) is at
least halfway up, shake/move the machine to shake the
water and any possible deposit.
Connect the flexible hose to the connector block (5) of
the machine, and hook the

“TANK SUCTION”

accessory into the handle, insert the accessory tube
into the tank (7) and completely suck the water in it.

(Operation also possible in the tank (8))

2- The machine must be cold or definitely discharged
from the steam pressure and the plug disconnected.
Exhaust  the  contents  of  the  boiler,  carefully  following
what  described  in  the  previous  point  "BOILER
DISCHARGE".
Prepare 2 liters of water and vinegar, in proportions of
about 60% vinegar 40% water.
Insert  the  prepared  liquid  in  the  refill  tank  of  the
machine (7).
3-  Turn  on  the  machine,  wait  until  the  pump  finishes
filling  the  boiler.  (att:  it  may  be  that  during  the  first
charge cycle, the water end indicator lights up and the
machine must be switched off /  on again to complete
the  load).  When  the  pump  has  finished  loading  the
boiler  and  stops,  immediately  switch  off  the  main
switch, unplug it and leave the machine at rest for 6-7
hours.
(Att: do not leave the solution after the indicated times).

advisable to check if the caps under the machine leak,
in this case check their closure with a wrench or (with
the machine discharge and cold) replace the seal with
an original spare part.
