HANDLING AND RECOVERY
Attention
Before moving the equipment it is necessary to:
• stop the machine in accordance with the indications
set out in the "STOP" paragraph;
• disconnect the electricity supply, removing the plug
and winding the cable;
• shut off the water supply tap and unscrew the water in-
let pipe.
Handling can be carried out by lifting or, if the machine is provided
with the carriage, by tipping it and making it run on the carriage
wheels.
The machine must be stored in a protected location. Where it is
stored for a long period of time, it is necessary to completely empty the
water circuit (operating the machine for a few seconds with the water
supply off and with the spray gun on) and protect the machine from
dust. When functional once again, it is necessary to check that there
are no cracks or cuts in the hydraulic pipes.
PRECAUTIONS AGAINST FREEZING
During the winter season, the high pressure cleaner must not be
exposed to freezing, unless during normal functioning. We therefore
recommend, when operational activity has ceased, and before complete-
ly stopping the machine, closing the water supply tap and allowing the
high pressure cleaner to function until the hydraulic circuit is completely
empty.
Where there are extended pauses at low temperature, we recom-
mend using an antifreeze product. After emptying the hydraulic circuit,
operate the high pressure cleaner, directly taking up the antifreeze liquid
through the water intake pipe until completely filling the hydraulic cir-
cuit.
Antifreeze liquid is a harmful product for the environ-
ment, and as a result it is important to follow the in-
structions set out on the product packaging.

8. MAINTENANCE OPERATIONS

Attention
All the operations described in this paragraph must only
be carried out by professionally qualified personnel.
Attention
Use only original spare parts; contact technical assis-
tance centres for any requirements you may have.
For regular and safe functioning of the machine, it is necessary to
periodically carry out the operations set out in the rest of this para-
graph.
Attention
Before starting the operation it is necessary to:
• stop the machine in accordance with the instructions
set out in the "STOP" paragraph;
• disconnect the electricity supply, removing the plug;
• turn off the water supply tap and unscrew the water in-
let pipe.
PUMP OIL CHANGE
Where it is necessary to change the pump oil, use a mineral base
oil (110 g) with SAE 20W40 gradation.
The oil collected must not be dispersed in the environ-
ment but disposed of in accordance with current regula-
tions.
WATER FILTER CLEANING
The filter, which is located within the rubber pipe junction at the en-
trance of the H.P. pump, must be frequently cleaned and carefully re-
assembled to avoid any intake of air. Use pliers to extract it from the
pump and rinse it carefully under running water (see Fig. 6).
