GroundingInstructions
This appliance must be grounded. If it should
malfunction or breakdown, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock. This appliance
is equipped with a cord having an equipment-
grounding conductor and grounding plug. The
plug must be plugged into an appropriate outlet
that is properly installed and grounded in accor-
dance with all local codes and ordinances.
WARNING: Improper connection of the equip-
ment-grounding conductor can result in a risk of
electric shock. Check with a qualified electrician
or service person if you are in doubt as to
whether the outlet is properly grounded. Do not
modify the plug provided with the appliance.
For a grounded, cord-connected appliance ra-
ted less than 15 amperes and intended for use
on a nominal 120-volt supply circuit, the instruc-
tions in either item 1 or 2:
1) This appliance is for use on a nominal 120-
volt circuit, and has a grounded plug that looks
like the plug illustrated in sketch A at page 2.
A temporary adaptor that looks like the adaptor
illustrated in sketches B and C may be used to
connect this plug to a 2-pole receptacle as
shown in sketch B if a properly grounded outlet
is not available. The temporary adaptor should
be used only until a properly grounded outlet
(sketch A) can be installed by a qualified elec-
trician. The green colored rigid ear, lug, or the
likeextending fromtheadaptor mustbe connec-
ted to a permanent ground such as a properly
grounded outlet box cover. Whenever the adap-
tor is used, it mus be held in place by a metal
screw.
Note:InCanada,theuse ofatemporary adaptor
isnotpermittedbytheCanadianElectricalCode.
2) This appliance is for use on a nominal 120-
volt circuit and has a grounding attachment plug
that looks like the plug illustrated in sketch A at
page 2. Make sure that the appliance is connec-
tedtoanoutlet havingthe sameconfiguration as
the plug. No adaptor should be used with this
appliance.

3. Starting the unit and handling
3.1 Connect the upper section of the vacuum
cleaner to the power nozzle
Unscrew both fastening screws from the upper section of the
vacuum cleaner before assembly.
Push the upper section of the vacuum cleaner upright onto the
brush head. Then insert the two support arms into the grooves
provided on the upper section of the vacuum cleaner. Fasten
with screws. Tighten screws firmly.<Figure 2>
Connect the hose to the brush head and upper section of
vacuum cleaner. Plug the connecting cable with plug at the
bottom of the power head into the female receptable at the
bottom of the vacuum housing. <Figure 3>
3.2 Storing and removing cable
The vacuum cleaner’s power cable can be wounded up around
the upper and lower cable clips. The entire cable can be easily
removed by turning the lower cable clip.
3.3 Onandoff positions
The power nozzle has a pivot latch which locks the unit in the
upright off position. To operate, tread on the latched pedal and
tip the handle backwards. <Figure 4>
Caution: do not drive the rotating brushes over the connecting
cable. Carry the unit over steps and high thresholds.
3.4 Working with the suction hose <Figure 5>
Switch the unit on via the ON/OFF switch (green light still
illuminated) .
Please note: The carpet brush switches on automatically once
the suction hose with handle is firmly located in the motor
housing. Please check.
If the suction hose with handle is pulled out of the motor housing
for vacuuming, the brush drive motor switches off automatically.
The suction hose is streched when removed and increases the
working radius for above-the-floor cleaning.
The hose handle can be separated in the middle (bayonett
connection). The crevice and upholstery nozzle can be atta-
ched to both ends.
Important: Never use the hand pipe for vacuuming without first
attaching either the crevice nozzle or the upholstery nozzle (the
cleaner will malfunction if the end of the hand pipe is worn down
– see Section 6 for Troubleshooting).
The suction handle is inserted back into the vacuum motor
housing to activate the brush motor.
