Operation

1. Inflation
a- Valve cap
b- Plunger
a) To inflate the chamber, first unscrew the valve cap by turning a quarter of a turn counterclockwise. Check
that the plunger in the center of the valve is closed i.e. upper position. If closed i.e. spring compressed, down
position, push the plunger down and rotate to the closed position.
b) Connect the air pump to the valve, rotate the connector into the valve to lock it and start inflating. No matter
you used foot pump or electrical, please do not inflate over the maximum air pressure 0.25 Bar per chamber.
c) Use air gauge to measure the tube pressure.
d) Be sure to inflate each chamber in turn according to the sequence shown below. Do not inflate a chamber
completely then move on to the next one. Start with the rear chambers. Repeat procedure until all chambers
are evenly inflated to the recommended working pressure.
e) When inflating, please keep the air pressure balance between air chambers to avoid the damage of
bulkheads.
f) Inflatable boats can be damaged by extreme internal air pressure. Such pressure can be caused by
temperature differences. A boat properly inflated in the morning may become dangerously over-pressurized
as the day warms up. The internal pressure can multiply many times as the surfaces temperature increases
and under such conditions, seams can separate and bonded materials can delaminate. Avoid subjecting your
inflatable to such conditions by relieving pressure in all chambers of your boat as the day heats up or before
leaving the boat exposed to hot midday sun. It is highly recommended that the boat be stored in the shade
or under cover when it is not being used.
g) Using the boat with under inflated tubes may cause serious damage, including transom cracking.
