WARNING: make sure no swimmers or floating objects are in the vicinity before switching on the thru-
ster. The hydraulic thruster is a system component. The system must have these given characteristics.

7 - System Characteristics

• The initial contamination level of the fluid used to fill the system shouldn't exceed class 18/15 (ref. ISO 4406).
Such a level shall be kept by means of a suitable filtering, performed by the system filter itself, according to the
chart below.

• The system shall have a filter to keep the oil free from impurities.
• The installation of an exchanger or the use of a well-dimensioned oil tank is suggested, in order to prevent the oil
maximum temperature from exceeding the values recommended for the hydraulic fluid used.
• The use of specific fluids for hydraulic circuits with a mineral-oil base are recommended; they shall have good
wear-proof and antifoam features, with quick de-aeration, antioxidant, corrosion-inhibiting, lubricant properties,
and shall be compliant with the requirements of DIN 51525 and VDMA 24317 standards, with kinematic viscosity
included between 10cSt and 100cSt.
• Operating temperatures shall be included in the range between -10°C and +80°C.
• The whole hydraulic system is responsibility of the installer, whom according to the described specifics and the
operating requirements shall preserve the propeller from potential damages deriving from the system itself.
• The motor shall not be used with higher pressures than those indicated.
• Higher values may jeopardize irreparably the integrity of the motor itself.
• Follow carefully Quick indications to obtain the highest efficiency from your product: in different setting condi-
tions, do not exceed the maximum pressure values listed in the chart.
• In no case shall the maximum pressure in the draining arm exceed 6 bar.
• The installation of a pressure-relief valve (set at 10% - 15% higher than the maximum operating temperature of
the control valve) is recommended, in order to protect the system from any damage deriving from a mechanical
stoppage of the system.
• The installation of an electronic or hydraulic system, capable of delaying the motor motion reversal is recom-
mended, in order to preserve the gearbox from damages.
