ADVICE ON USING DETERGENTS
This cleaner has been designed for use with the detergents
supplied or recommended by the manufacturer.
The use of other detergents or chemicals may inuence the
safety of the cleaner.
1) For environmental compatibility, we recommend a rea-
sonable use of detergents (g.9), according to the instructions
on the pack.
2) From the range of recommended products, choose the
one most suited to the washing job to be done and dilute it
with water according to the instructions on the pack or in the
catalogue of the detergents most suited for the type of hot or
cold water cleaner.
3) Ask your dealer for the detergents catalogue.
OPERATING PHASES FOR CORRECT CLEANING WITH
DETERGENTS
1) Prepare the solution of detergent at the concentration
most suitable for the type of dirt and the surface that is to be
washed.
2) Start the cleaner, turn on the detergent tap (if present),
switch on the detergent suction control on the lance (g. 10)
and spray the dirty surface with the diluted product, working
from bottom to top.
Let it react for a few minutes.
3) Rinse the whole surface well from top to bottom at high
pressure.
4) After using with detergent, ush out the intake circuit; place
the detergent suction hose (g. 8) in a tank of clean water and
let the pump run for 1 minute with the dosing tap turned fully
on and the lance in detergent delivery condition.
