means of the levers located on the sides or on
the handle with BOTH HANDS!
ŸDanger of crushing upper limbs when fitting and
locking the container on the machine.
Using the filter shaking system
ŸThis operation must only be performed with the
machine switched off once the motor has come to a
complete halt.
ŸThe filter shaking system is best operated every time
before use and after prolonged operation.
During vacuuming, avoid rolling up or twisting the
flexible hose
ŸOn the front of the machine is a vacuum meter
indicating the degree of vacuum inside the machine.
- Never use the machine with the filter blocked.
- If the arrow of the vacuum meter stays in the red
area even after cleaning the filter, the hose or
