ASSEMBLY

(
Unfold the boat on smooth and clean ground, on a trailer or a craddle.
Start to inflate as indicated. When inflating,
pressure compressor, it could spoil the performance of the valve, the
bulkheads or even the tube. Use only the supplied bellows.

excessive pressure and avoiding eventual risks of bursting (consider
that pressure increases with temperature +1°C = +0,003bar and with
atmospheric pressure +1mB atmospheric pressure = +1mB of
pressure in the tube). This safety valve is marked "
VALVE - DO NOT TOUCH".
The recommended inflation pressure for all compartments is
When this pressure is reached you will notice a strong resistance on the bellows making
operation difficult, it means the compartment is correctly inflated.

VALVES

( WARNING)
Make sure the central spindle of the inflation valve is in "closed" position (outwards). If it were
not so, press and turn it towards the right, it will lock by itself.
Insert the appropriate mouthpiece of the bellows in the valve and start to inflate the
compartments in the order mentioned above until a MAXIMUM 0,20 bar pressure is reached.
Next, remove the mouthpiece of the bellows and screw back the cap of the valve. This will
prevent water and dirt intake.
For deflation remove the cap of the valve, press the spindle inwards and to the left where it will
block itself in "open" position. Deflate the compartments completely and release the spindle of
the valve, placing it in the "closed" position. Screw the cap back into place.

LIFTING AND LAUNCHING

The rescue boat is supplied with a four-legged sling
designed to stand the weight of the boat, its equipment, its engine with fuel and 6 persons (total
885 kg.). This maximum load must not be exceeded (for example, lifting the boat with water
inside).
When launching, it is convenient to activate the release hook before the boat touches the water,
as it could capsize in case the vessel sails at high speed and the boat is hauled by a point that
is not suitable (lifting sling).
Bear in mind that this boat is designed to withstand a free drop from several metres, fully
loaded, but the persons could be harmed.

TOWING

The rescue boat is to be towed by the anchoring / mooring ring
there is a 20 metre-line for that purpose, as well as a release device that allows to free the line
