INFLATION / DEFLATION VALVE OPERATION.
The valve has twopositions of slidingpart Acorresponding
to its two conditions (modes):
– sliding part A is with drawn - operation condition of
the valve (compartment air filling mode);
– sliding part A is recessed - valve in condition "OPEN"
(compartment air discharge mode).
In order to switch the valve over from one condition to
another, just press sliding part A with your finger to turn
it by 90 degrees in any direction until it is fixed (See Fig.1).
Prior to begin the compartment filling process set all valves
in the operating condition. On completion of filling close the

MAINTENANCE
Main conditions of long service life is right and careful service.
Avoid excessive increasing of pressure in the board,
especially from heating by the sun rays.
After exploitation take off sand and dirt from boat surface,
and carefully dry it.
Avoid the water getting into the chambers. If a fuel or an oil / gas
gets to the boat surface it is necessary to wash the soiling place by
soap water as soon as possible and dry.
Pay attention to the condition of bottom and seat surfaces. If
the coating is destroyed it is necessary to dry this element and
restore the defend ply.
After the season prepare the boat to winter keeping. Clean
boat surface from sand and dirt and make the necessary
repairs, if damages take place. If it is possible, keep the boat
in the open and slightly pumped state in air temperature 0-
25°C. The boat must be protected from the sun rays.
Insignificant boat repairing (eliminating the board punctures
or cuts) you may carry out by yourself. In this case use the
coated fabric patches from the complete set. Ask your dealer
for the correct type of glue you may use for the repair.
In case if sufficient damagesof hull, tube body, partitions
or seams it is recommended to apply for professional repair in
authorised service station.
OPERATING REGULATIONS
Dear user,
Wethankyour foryourpurchase anddohope thatyouwill have
a great fun of it. However, to make your joy and pleasure
complete, we would request you to read carefully and observe
the directions and recommendations specified below.
IT IS STRICTLY FORBIDDEN :
to handle the boat in the state of intoxication and without individual
rescue means being used (life-saving belts, jackets, etc.)
IT IS FORBIDDEN :
- to overload the boat above the design weight-carrying capacity;
- to use an outboard engine of power exceeding the maximum
allowable value;
- to bring the tube pressure up to the value exceeding the rated
one ( 0.15 bar);
- to drag the boat across a rough surface.
Danger of usage of engine having insufficient or exces-
sive power
According tothe safetyregulations, eachinflatable boatshould
be furnished with an outboard engine having the maximum
allowable power. You will find the data on the maximum
allowable power of the engine on the manufacturer's plate with
the designation of the model type inscribed thereon. The plate
is fixed in the afterbody of the boat. However, your should
choose the engine power within the allowable range so as to
ensure that you may safely reach the shore when heading into
the wind or into the current.
Observation of local shipping regulations
For each particular water area the local shipping regulations
are in force. You may apply for information to the appropriate
water transport and shipping directorate, as well as to the
water police.

OPERATING REGULATIONS

occupiedseatsshould notbeleft throughout the entire sail ing
time. When sailing with an outboard engine the steersman
should shift his body forward in the course of acceleration
to prevent the boat forebody from raising under the force
of upthrust waves.
Presence of sharp and pricking objects on board
Despite the strong shell of the boat we are recommended
to handle sharp and pricking objects being on board with
care. For example, it concerns a knife blade, fish-hook
point, etc.
Rocky shore, mole, shoals (for example, sand
banks, coral reefs, rocks)
Approach rocky shores, shoals, moles, etc. carefully to
avoid damages to the boat. It is strictly prohibited to drag
the boat across rough surfaces (shingle, rocks, concrete,
etc.).
Check at navigation
Incaseofprolongednavigationwiththeuseofanoutboard
engine,regularlychecktoensurethattheengineisreliably
attachedto theboat.Iftheenginewasattachedcarelessly
theattachmentmayworklooseundertheactionofvibration.
Besides,checkairchamberspressureatregular intervals,
since the pressure may vary under the effects of outside
air temperature and atmospheric pressure variations.
Neverforgettomonitorregularlythe quantity of fuel in the
fuel tank. Keep always in mind that the quantity of fuel
shouldbe sufficientfor youtosailtoyourfinaldestination.
Availability of rescue means (life-saving jackets,
distress signals, spare parts)
Ifyouareplanningtogobeyondthe protectedwaterareas
you should provide all passengers on board with life-
saving
Proper usage of boat equipment and accessories
Use the boat equipment and accessories only on their direct
purpose to ensure reliable service.
Availability of Oars
Even when sailing with an outboard engine you should always
have the oars available with you so that you were able to reach
the shore without outside assistance in case of any damage to
the boat.
Usage of emergency stop switch
On your request any outboard engine seller may provide your
engine with the emergency stop switch. During navigation the
switch should be connected to the wrist of your hand by means
ofacord. In caseyoufalloverboard, evenifbeinga steersman,
the switch will cut out the engine and the propeller. This
arrangementwillenableyou to avoid any traumasandtoreach
the boat.
Prevention of damages caused by electrolyte or fuel
leakages
Take all possible precautions against penetration of fuel or
electrolyte from the storage battery into the inflatable boat. If it
does happen wash thoroughly the fouled spots with water.
Cargo arrangement and stowing, attachment of items
and prevention of falling overboard
You should be always sure that the number of people on board
never exceeds that specified in the user's manual or on the
manufacturer's plate provided on the transom. The boat will
retain an adequate floatability and will not keel over only
provided that the load is arranged reasonably. Therefore,do
not accommodate all passengers on the same side of the boat.
Arrange the cargo to be carried uniformly inside the boat, all
items being reliable secured on the bottom of the boat. All
passengers should be accommodated inside the boat. The

jackets. All passengers should put on life-saving jackets
under strong wind and heavy seaways conditions. Those
passengerswho cannotswim shouldalways carrythe life-
saving jackets while on board! It is also recommended to
keep constantly distress signal means on board.
Towing
At towing the towing rope length should not be at least 3
lengths of the boat, the rope being secured to both boats
in a manner ensuring its immediately, single-motion release.
Thesteersmanof thetowedboat should beassistedby another
crew member to monitor the process of towing. In this case,
certain communication gestures should be agreed upon
beforehand.
Damage to one of air chambers
Theinflatableboatis designedtoprovide anadequatestability
in case of the complete damage to one the air chambers
(balloon compartments) at the expense of the remaining air
chambers and the hull. Thanks to it, you will be able to reach

to the undamaged part of the boat. Watch changes in stability.
After this immediately head for the nearest shore. To prevent
penetration of water into the boat, pull the shell of the damaged
air chambers upwards.
Anchor and mooring fast fastening
Fix the anchor and towing ropes in the forebody of the boat to
the front towing ring. Fix the back spring on the transom via
special holes.
Danger of currents and wind
Before navigation of the boat in unfamiliar waters make detail
inquiries about local conditions and regulations! Currents,
wind, shoals, rising and falling tides, as well as weather
variations may imply serious danger!
