should happen, wait for at least 24 hours before using the machine, so that the liquid that
may have penetrated inside the device has time to evaporate.
• For oil fired machines without a flame safety control: Do not leave the machine unattended
during operation.
• When the high-pressure water cleaner goes into Total Stop, the lever of the gun must be
blocked with the safety device and make sure that it is not inadvertently activated.
PRECAUTIONS FOR CORRECT USE
If the indications below are ignored, there is a strong possibility to
CAUTION
damage the machine.
• See the table in paragraph "SPECIFICATIONS AND TECHNICAL DATA" and observe the supply
water values of the: minimum flow-rate; maximum and minimum temperature; maximum and
minimum pressure (maximum priming depth): if in doubt, contact a QUALIFIED TECHNICIAN.
• If priming a tank, it is advisable to fit a supplementary filter at the end of the suction pipe
(contact your dealer in this regard).
• Do not operate the machine:
- Without water supply;
- With brackish water or water containing impurities: if this should happen, run the cleaner
for a few minutes with clean water;
- For more than three minutes in by-pass (gun closed), if the Total Stop is not available or
if cleaning at a very low pressure so that the device does not activate (refer to the technical
data table of paragraph "SPECIFICATIONS AND TECHNICAL DATA");
- If it is excessively noisy and/or there are significant water or oil dripping;
- In direct sunlight, with a surrounding temperature greater than 40°C/104°F.
• If used under very low temperatures, make sure that ice has not formed inside the pump and
the pipes.
• In order to avoid incrustations and/or deposits of chemical products after using detergents,
the circuit should ideally be cleaned by aspirating clean water for a few seconds.
• Carry out the foreseen routine maintenance controls with particular reference to the oil.
• The machine does not like frost.
To avoid the build-up of ice inside the machine in harsh environments, a car anti-freeze
product can be aspirated before carrying out the "STOP" procedure. Before doing so, contact
a QUALIFIED TECHNICIAN because the pumped liquid could damage the high-pressure seals
of the pump. If the machine could not be protected as previously indicated, place it in a warm
location for a sufficient time before starting so that the ice that has formed inside can melt:
The machine could be seriously damaged if these simple instructions are not followed.
