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 possi
ble, 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.
We use only top quality stainless steels, which are resi
stan to corrosion. However, it is not permanent and
maintenance is required:
-Avoid contamination and scoring its surface,
-Frequently wash with fresh water,
-Grease and mirror polish it regularly.
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
OA Dear user,
We thank your for your purchase and do hope that you will
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/ 2.15 psi );
- to drag the boat across a rough surface.
Danger of usage of engine having insufficient or
excessive power
According to the safety regulations, each inflatable boat
should 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.
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 of a cord. In case you fall overboard, even if being a
steersman, the switch will cut out the engine and the propeller.
This arrangement will enable you to avoid any traumas and to
reach 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
occupied seats should not be left throughout the entire
sail ing time. When sailing with an outboard engine the
steersman should shift his body forward in the course of

GRAND Golden Line G850 UM18500
12
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
In case of prolonged navigation with the use of an outboard
engine, regularly check to ensure that the engine is reliably
attached to the boat. If the engine was attached carelessly the
attachment may work loose under the action of vibration.
Besides, check air chambers pressure at regular intervals,
since the pressure may vary under the effects of outside air
temperature and atmospheric pressure variations.
Never forget to monitor regularly the quantity of fuel in the fuel
tank. Keep always in mind that the quantity of fuel should be
sufficient for you to sail to your final destination.
Availability of rescue means (life-saving jackets,
distress signals, spare parts)
If you are planning to go beyond the protected water areas
you should provide all passengers on board with life-savi
ng jackets. Those passengers who cannot swim should
always carry the 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. The
steersman of the towed boat should be assisted by 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
The inflatable boat is designed to provide an adequate stability
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
safely the nearest shore. Reduce the speed and shift your
body 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!
In emergency stay in boat
In any unexpected situation (engine failure, boat damage,
etc.) do not ever leave the boat provided it is still afloat. Even
if you believe that the shore is just nearby stay in the boat,
since you will be looked for in this particular place and, most
probably, will be found. Should the boat become partially
flooded throw heavy objects (batteries, fuel tank, engine)
overboard to ensure additional floatability.
The "GRAND" Company employees would like to wish you a
pleasant and safe leisure time!
