CHECKING THE WATER INTAKE FILTER
Inspect and clean the water intake filter on the in-
take union periodically. This is important to prevent
fouling which may impair operation of the pump.
CLEANING THE FUEL FILTER
Check the fuel filter periodically and replace if it has
deteriorated or is excessively dirty.
DESCALING
The descaling procedure must be carried out periodically
with specific products. The interval depends on the hard-
ness of the water. Pour one litre of product for every 15
litres of water into a drum containing at least 30 litres of
water. Disconnect the gun from the high pressure line and
place its free end in the drum, in order to form a closed cir-
cuit, and draw the solution into the machine for at least 10
minutes. The delivery end of the line should discharge into
a canvas or mesh bag so that the scale removed is not re-
turned to the circuit. Then restore the normal connection
and rinse with plenty of cold water. This operation should
be carried out by our after-sales service, since the descal-
ing product may cause wear of components. Comply with
the regulations in force when disposing of the descaling
agent.
Liquid softener tank integrated
(Optional - if included)
The descaling procedure must be carried out pe-
riodically with specific products. The interval de-
pends on the hardness of the water. This opera-
tion should be carried out by our after-sales serv-
ice, since the descaling product may cause wear
of components. Comply with the regulations in
force when disposing of the descaling agent.
- Fill the softener tank with our products (in
all cases, with non corrosive products). The
dispensing rate is set at a medium value; the
After Sales Services will be able to adapt the
setting to local conditions.
