12 Emptying the container
Industrial vacuum cleaners with antistatic design need to be emptied after
every single use.
First of all, switch the motor off. Wait a moment until the dust has settled down before
you separate the dust collecting container from the upper part of the machine:
Lower the container by using the lifting mechanism.
Switch the motor on again in order to prevent dust
falling down from the filter.
Move the dust collector forwards.
Replace the disposal system.
Move the dust collector back under the machine.
Switch the motor off.
Push the dust collector upwards by using the lifting
mechanism.
