Monitoring pressure loss:
1. Fill the container up to the pressure level of 8,5 bar.
2. Watch the manometer.
3. After 1 hour read the pressure difference on the manometer.
Monitoring ball valves:
1. When filling and emptying the Booster device, pay attention to
the valve lever whether it can be moved freely.
INTENDED USE
Booster serves as an aid in inflating tubeless tyres. A common
problem in this kind of tyres is the air that goes through the valve and
leaks through the aperture between the rim flange and the rim fringe
protector which prevents the tyre from being inflated. The solution
for this problem is a rim for inflating the tubeless tyres. It is available
in different sizes for different rim diameters.
Booster is a universal device supporting tyre inflation as it can be
used for rims with different diameters. The pressure container serves
as a sort of a “means of transport” for the compressed air.
Compressed air is inflated into the tyre very fast through a special
valve, so that the rim fringe protectors almost immediately fit tightly
to the rim –thanks to this, the inflating process continued through the
valve can be successfully finished.
UNPACKING
Check for damage
Right after you collect the package, check to ensure that it was not
damaged during shipping. Bear in mind the legally defined deadlines
for returning the package.
OPERATING AND SAFETY INSTRUCTIONS
WARNING:
The Booster device can be used only for purposes described in
this user guide.
Storage
If the device is not used, you must store it in an empty state:
constricting nozzle must be directed downward, so that the
condensed moisture can drain away.
Safety valve
Safety valve opens when the pressure exceeds the permissible value
(9 bar).
Filling with compressed air
The container must be filled only with clear, dry and de-oiled air at
an ambient temperature. The pressure of the compressed air cannot
exceed 9 bar.
Noise
Hearing protection must be used when the device deflates the air.
WARNING:
The Booster device makes noise which may damage your
hearing, therefore, you must wear hearing protectors.
The device makes noise at the level up to 135 dB. The
measurement took place with an open constricting nozzle; when
filling up the tyre, the noise level will be lower. When tyres are
inflated 6-10 times a day, the average level of noise will remain
below 70 dB. Workers who are nearby the place of tyre inflating
process, must also wear hearing protectors.
Eye protection
You must wear eye protection, regardless the place where
the device is being emptied. There is a danger that dirt,
dust, rust and other foreign objects may be raised by the
stream of air..

2.4 Inflating the tyre in a vertical position
• Put the inflating hose on the valve and start inflating.
• Put on the hearing protectors and the eye protection.
• Set the Booster opposite the valve at an angle of 70oC tot
he horizontal and start inflating the tyre by a quick move
oft he main valve lever.
Check for completeness oft he consignment
WARNING:
The assembly paste for tyres may be thrown away by
compressed air.
GENERAL INFORMATION ON USAGE
Correct pressure in a container
Correct pressure values for individual types of tyres are specified in a
table on page 14. It is recommended to follow the provided values.
Assembly paste for tyres
Use sufficient amount of assembly paste for each type of flanges and
rims. Insufficient amount of the paste may cause the rim fringe
protector moves away from the rim.
Correct setting angle
The correct setting angle between the device and the rim is very
important. The inflating effect will be undermined if the air stream
meats the rim or the rim fringe protector and losses its speed there.
The perfect place to inflate the air is the spot between a rim flange
and a tyre.
Correct position of the device
The most effective way to inflate is to place the device opposite the
valve. This way the air will be inflated to the tyre from both sides.
The space between the rim and a rim fringe protector should be as
big as possible. It enables a free and undistorted air inflation from the
cantainer

THE USE OF BOOSTER DEVICE
1. Filling the container with compressed air
• Close the main valve.
• Close the air pressure valve.
• Connect the Booster to the compressor with a inflating hose.
• Check first whether the pressure in a compressor does not
exceed. The permissible container pressure value.
• Connect the inflating hose to the PCL connector from the container.
• Open the air pressure valve.
• Monitor the inflating process on the manometer.
• Recommended air pressure –see page 14.
• Close the air pressure valve.
• Remove the inflating hose.
2. Preparing the wheel and starting the process of inflating
2.1 Preparing the wheel in a horizontal position
• Carefully apply the assembly paste on a tyre.
• Set the rim and tyre so that the lower rim fringe
protector is closely fitted to the rim.
• Aim the front of the rim and the valve upwards.
• The upper rim fringe protector in the area near the valve should
be fitted to the rim as closely as possible. It is good to place the
wheel chock under the tyre.
2.2 Inflating the tyre in a horizontal position
• Put the inflating hose on the valve and start inflating.
• Put on the hearing protectors and the eye protection. Turn the
constricting nozzle in such a way that its flange is on the same side
as the main valve lever.
• Set the Booster opposite the valve at an angle of 70°C to the
vertical and start inflating the tyre by a quick move of the main
valve lever.
2.3 Preparing the wheel in a
vertical position
• Carefully apply the assembly
paste on a tyre.
• Lean the rim and the tyre
against the wall in such a way
so that the lower rim fringe
protector is fitted closely to
the rim..
• Turn the front of the rim and
the valve towards you.
• The upper rim fringe protector
in the area near the valve
should be fitted to the rim as
closely as possible. It is good
to place the wheel chock
under the tyre.
