When using the boat for the first time, screw in the screw valves with tender feeling firmly into the
bases of the air chambers 3 and 5.
Do not yet step onto the boat as long as it has not yet been inflated, in order to avoid damaging
the plastic sheet.
Inflating the boat
For inflating the boat please take a pump out of the WEHNCKE inflating pump collection.
Never use a compressor or compressed air!
The air chambers are to be inflated in the order of the numeration.
The procedure for inflating is as follows:
The floor chambers, the accompanying seats and back rests as well as the lower main chambers
are to be inflated via the plug valve by utilizing a suitable adapter that is accompanying the pump.
For this purpose, the valve must be completely pulled out and the plug must be removed. The
valve is to be closed again by means of the plug, subsequent to the inflating procedure and after
the adapter has been removed. Subsequently, press the valve inwards as far as possible into the
air chamber.
Unscrew the closure of the screw valve of Air Chamber No. 3 and connect the pump. When using
a dual stroke pump, connect the connecting hose to the pump socket marked with “Inflate” and
firmly insert the adapter in the opened valve. Remove the adapter after filling has been completed
and screw again the screw closure onto the valve.
The inflating procedure of Air Chamber No. 5 is effected in the same way.
The inflating procedure is to be continued until the nominal operation pressure of the respective
air chamber has been achieved. The operation pressures of the individual air chambers are stated
in the Table shown below. For checking the nominal operat¬ing air pressure, checking devices
have been installed on the two main air chambers. The operating pressure has been achieved as
soon as the top of the display ribbon points onto the marking stroke corresponding to the environ-
mental temperature (see Illustration 1).
Additional air chambers, as far as existing, also to be inflated in the manner described above.
Whether the required operating pressure has been achieved can be determined by pressing in
with one’s thumb in comparison with the main chambers. The plastic sheet must allow itself to be
pressed with medium force still approximately 1 cm deep.
Deflating the air chambers
For the deflating procedure of the air chambers, the complete screwed valve must be removed by
screwing it out. In order to assist the deflating process, utilize the little tubes attached, which have
to be inserted in the valve socket for this purpose.
For a controlled reduction of the air pressure of the buoyancy chambers, open the closure of the
screwed valve, press in briefly the pin that will become visible for opening the check valve until the
required reduced air pressure has been achieved.
For the deflating procedure of the floor chambers, lower main chambers, seats and back rests, pull
out the valve from the air chamber and pull out the plug from the valve neck. Press the valve neck
by means of two fingers in such a way that the air can escape. When the com¬plete evacuation of
air from the air chambers is intended, press the air chambers forcefully in addition.
