OPERATING THE VACUUM CLEANER
1. Release the power cord from the cord hooks (2) at the backside of
the vacuum cleaner. Turn the lower hook so that the cord is released.
Unwind the whole power cord .
2. Adjust the height of the handle, by pushing at the handle lock button
(4) and then pull or push at handle to comfortable height.
3. Add the cord to the hook of the handle in order to make an anti strain
function. Then plug-in the power cord into a electrical outlet.
4. Turn the Main Power Switch (17) ON. “l” is ON and “O” is OFF. Now
the vacuum motor will start.
5. Step on the Pedal (11) and then tilt the cleaner backwards. Now the
brush motor will start (DUAL-versions only). At DUAL-versions the green
light (7) at the brush housing (9) will come on to indicate that the brush
motor is running. On single-motor versions, the brush is always turning
when on.
6. Turn the Height Adjustment Knob (10) to adjust the height that the
brush will operate in - depending on the material at the surface to be
vacuumed. For carpets with short textiles the brush should in the lower
position. Turn the knob to the left (when you are placed in front of the
machine) to lower the brush. For carpets with longer textiles the brush
should in a higher position. Turn the knob to the right (when you are
placed in front of the machine) to set the brush at a higher level. If the
red light comes on, slowly turn the knob in the opposite direction until
the light goes off (Dual-versions only).
If the red light (8) stays on continuously, there may be debris wrapped
around the brush, during operation. On double motor units this can
cause the overload protector for the brush motor to trip. If this occurs,
turn the Main Switch (17) OFF and unplug the power cord. Remove any
debris from the brush and plug in the power cord, turn the Main Switch
(17) back ON. This will automatically reset the overload protector. If the
overload protector trips repeatedly contact your dealer for service. For
more information of the light indicators on the DUAL-versions - see the
table below.
NOTE! Always disconnect the power cord before performing any
machine maintenance.
Change the bag whenever the “Bag Full” indicator (15) comes on.
For details of dust bag replacement see separate instruction in this
manual. If the light comes on before the bag is full, the inside of the bag
may be coated with very fi ne dust (change the bag), or debris may be
built up somewhere between the brush and the bag.
IMPORTANT !
Foot pedal must be used to
release base to
operating/non operation
position. Failure to do so
could result in damage to the
handle release mechanism.
