Checking the rotation direction of the vacuum unit
motor
Check the vacuum cleaner operation by putting a hand on the
inlet.
If the vacuum cleaner blows air out of the vacuum hose, the
motor rotation direction is wrong; disconnect the machine from
the electrical mains and invert two of the three
phase wires inside the power plug or inside the electrical
panel to which the power cable is connected.

Shaking the primary filter
VHW310 / VHW311 version
In case a filtering capacity reduction occurs when using the
vacuum cleaner, the primary filter is to be cleaned by using
the knob (1).
WARNING!
Stop the vacuum cleaner before shaking the filter.
Do not shake the filter while the vacuum cleaner is on,
as this could damage the filter itself.
Wait before restarting the vacuum cleaner, to allow the dust
to settle. If the vacuuming capacity remains low, even after
shaking the filter, the filter element must be replaced (see
"Primary filter replacement" paragraph).
VHW311T version
Depending on the vacuumed dust quantity and if the pointer
of the vacuum gauge switches from the green zone (2) to the
red zone (3), turn the vacuum cleaner off and shake the main
filter with the knob (1).
WARNING!
Stop the vacuum cleaner before shaking the filter.
Do not shake the filter while the vacuum cleaner is on,
as this could damage the filter itself.
Wait before restarting the vacuum cleaner, to allow the dust to
settle. Replace the filter element if the pointer still remains in
the red zone (3) even after the filter has been shaken (consult
the "Primary filter replacement" paragraph).
Emergency stopping
Turn the main switch to "0" position.
