Setting the suction force
Suction force control unit
(1)
The On/Off foot switch (1) dually
serves as a suction force control
unit.
• Rotate the On/Off foot
switch (1)
–

tion.

Air by-pass vent
(26)
You can adjust the suction force
as needed by using the air by-
pass vent (26). The covering of
the air by-pass vent (26) can be
adjusted as desired.
Should you accidentally
allow the vacuum cleaner
to come into contact with
an object, opening the air by-
pass vent immediately reduces
the suction force. This remedial
action will prevent such items
from being drawn into the dust
bin.
