Vacuum gauge function
On the front side of the vacuum there is a vacuum gauge indicating suction pressure level inside the
vacuum. If the suction inlet is free and the vacuum gauge pointer indicates irregular suction pressure, it
is necessary to shake the filter.
If the optional automatic filter shake system is available, press the blue led switch and keep it pressed
for a few seconds to start filter shake functions.
If suction pressure value is still excessive, it is necessary to clean or replace the main filter or the
safety filter.
