Airtightness test
There are no leaks if the pressure of the manifold does
not rise for 5 minutes or more after leaving the pump and
manifold.
NOTE: When the battery remaining capacity becomes
low, LED lamp goes out and at the same time a long
alarm beep start sounding. About two minutes later
the motor stops. And then alarm beep changes into a
repeated short-time interval beeping which notifies the
motor stop and 30 seconds later the beeping stops.
However, do not wait until the motor stops (or alarm
beep changes to a short-time beeping), and instead
close the inlet valve of the tool and the low pressure
side valve of manifold.
