Problem
Possible Cause
Solution
No display
No power connected
Switch power on
No inflation process
Tyre is below 3 psi
Faulty connector
Press flat tyre button
Replace faulty connector
Buzzer does not sound
Buzzer volume has been turned off
Buzzer is damaged
Turn buzzer on
Replace buzzer
Inflation process starts but does
not complete
Low or no supply pressure
Leaks exist
Check supply pressure
Confirm leaks do not exist
Supply pressure leaks out input Input and tyre hoses are incorrectly reversed
Ensure input connection is to offset port, tyre
connection is central between input and exhaust
Inflating or deflating is very slow Check that mesh filters under input and output
port fittings are blocked
Clean and or replace mesh filters
Connector will not seal to the
tyre stems
Connector worn
Replace connector
Connector leak while not
connected to tyres
Connector worn
Replace connector
E1
Unstable or insufficient supply pressure
Check the supply pressure
E4
Small volume, caused inflator to check pressure
> 2bar / 29psi over target pressure
Check hose is not kinked or blocked, ensure a OPEN
END connector is installed
E5
Inflator started under pressure i.e. is connected
to tyre or a CLOSED END connector is being used
Remove hose from tyre and allow inflator to reset
Change connector to OPEN END type
