A good rule of thumb is: When you cannot depress the tube
more than 1 cm (1/2”) with the pressure of your nger, you
have then reached approximate working pressure.
Important:
The correct way to inate the air chambers is by inating the
rear chambers rst, and then those towards the bow. When
the inatable buoyancy chambers have been inated, screw
the cap on the valve properly in order to secure nal air
tightness. The buoyancy tubes must be inated to the
recommended pressure otherwise the craft will perform
Air tightness is obtained partly by means of the plunger
one-way check valve that is set in the base of the valve insert;
complete air tightness is ensured by the properly tted valve
cap. Before screwing on the cap, check that the valve is clean,
free from sand weeds or other debris.
To Deate:
Remove the cap and with your nger, push down the
spring-loaded plunger in the center of the valve. To deate
totally you may want to lock the plunger down.
The Hand Pump also called Cylindrical Pump:
To inate the ABJET boat, plug the valve connector to the
valve. Put it in an upright position and step onto the tongues
located at the bottom of the pump. The hand pump is double
action. Each time you lift and push the handle, 4lts (1 gallon)
of air will enter into the buoyancy chambers. The hand pump
comes with two connectors, one for ination and the other
for deation.
The Buoyancy Chambers:
Depending on the model you have chosen; it will have three
or more air chambers. Each chamber is divided by a special
bae system that keeps the multiple air chambers complete-
ly sealed o from one another, while working to equalize air
pressure between compartments. It is advisable to inate
your boat properly and check the pressure frequently. The
pressure should be maintained at 0,02 bar (3 Psi) in the
buoyancy chambers. (A pressure gauge is not included with
the boat).
NOTICE
The pressure of the boat uctuates with change in temperatu-
re.
Pressure increases after prolonged exposure to sun and falls
when the boat is launched and when in darkness. Do not
worry about this.
We have seen experienced people send boats over for repair
which were in excellent condition that either lost air due to a
WARNING
Care should be taken not to allow a boat which has been fully
inated in the cool of the morning to stand in direct sunlight.
Buoyancy pressure will quickly rise with the temperature and
could strain or cause serious damage to the buoyancy tube.
