the same side of handle. Insert bolt
through small holes and secure with
nut. Tighten nut with screwdriver.
Fig. 1.
If the nut and bolt are not assembled
as shown in the illustration, the holes
in the handle are not lined up correctly.

place the two projections at the bot-
tom of the outer bag assembly inside
the metal grooved plate. (You will
find the grooved plate extending out
from the bottom rear of the cleaner.)
Fig. 1.
Just above the opening at the rear of
the cleaner is the bag clip. Pull the
bag clip to the left and fit bag against
opening. When you release the bag
clip, it should move to the right and
fit completely over the bag lock.

Adjustment for carpet pile height
The cleaning of carpet and rugs takes
place at the nozzle. This is the opening
at the bottom of the cleaner where the
agitator is located. Fig. 1.
It is necessary to raise and lower the
nozzle for various carpet pile heights.
The adjustment lever raises and lowers
the nozzle for various carpet pile and
is located to the right of the bag near
the bottom of the cleaner. The pile
height adjustment displays in the
window on top of the cleaner. Fig. 2.
Select the desired nozzle adjustment
by moving the lever with your toe
until it "clicks" into the desired posi-
tion. Fig. 3.
You can most easily make adjustments
if you move the lever UPWARDS into
the desired position. Therefore, when
a downward adjustment is required,
first press the lever all the way down
into the SHAG position and then move
upwards one position at a time. The
nozzle adjustment display will indicate
each pile height as you move the lever.

SPECIAL FEATURES
Carrying handle
Your cleaner has a convenient carry-
ing handle located underneath the han-
die bail.
Edge cleaning
This feature improves the cleaning of
carpet edges near baseboards and solid
furniture. Dust and lint tend to collect
along these edges. The cleaner bottom
plate has been designed with a passage-
way for dirt to enter the nozzle from
the side to increase cleaning ability of
edges. From the right or left side,
slowly guide the cleaner parallel to
the edge of the carpet.
Cleaning lightweight flexible rugs
Lightweight flexible rugs used on hard
surface floors in entrances, bathrooms,
etc. should be cleaned by the following
method.
Stand on one end of the rug and move
the cleaner toward the other end or
edge. Before reaching the other end,
push down on the handle. This will lift
up the nozzle (front of cleaner) and
will prevent the rug from clinging to
the cleaner. Continue to lift up the
nozzle so that when you have reached
the edge, it is completely off the rug.
Move the cleaner back to start again
and lower the nozzle, using only for-
ward strokes.

E. Have cleaner in upright position when using cleaning tools.
USING CLEANING TOOLS
A. Attach converter
By using the converter attachment,
Fig. 1, you can channel the suction
from the cleaner to the hose and
cleaning tools. The converter must
first be attached to the vinyl hose;
then the converter is attached to the
bottom of the cleaner. Follow the
steps detailed here for attaching the
converter.
To attach the converter to the vinyl
hose, insert converter into hose con-
nector. Fig. 2.

Push connector and converter togeth-
er and twist.
The converter is locked into position
when the projections on the converter
fit into the holes on the hose connec-
tor. Fig. 3.
To attach the converter to the cleaner,
first unplug cord. Warning: Cleaner
must not be running when position-
ing or removing front converter.
Have cleaner in upright position.

C. Attaching the tools
After having chosen the proper tool
for your particular task, attach it to
the end of the vinyl hose.
The outer plastic ring on the end of
the hose has a slot which adjusts.
Note the slot in the hose grip. Turn
the outer ring until the slots align.
Fig. 6.
Insert the toot so that the button on
the tool fits into the slot in the end of
the vinyl hose. Fig. 7.

Turn the plastic ring counterclock-
wise to lock the tool in place. Fig. 8.
For additional length, attach one or
both* wands to the vinyl hose as de-
scribed in the preceding section.
To attach the tools to the other end
of the wand, press down firmly on
the white plastic spring latch. Fig. 9.
Fit the attachment into place and
release plastic latch when it fits over
button on tool. It is now locked in
place.
*Available with deluxe sets only.
D. Regulating the suction
The suction regulator is located on
the end of the vinyl hose attached
to the cleaner. Set the regulator by
turning the dial to minimum, medi-
um, or maximum suction. Fig. 10.
E. Engaging the higher speed for using attachments
Your cleaner is equipped with a two-speed motor. One speed is utilized when
the cleaner is being used on carpet and rugs, and a second higher speed is for
use with attachments.
Upon insertion of the converter and having the cleaner handle in the upright
position, the motor automatically adjusts to the higher speed.
Therefore, for effective operation it is important to have your cleaner handle
in the upright position when using the attachments.
When using the cleaning tools, the adjustment for carpet pile height should
be set according to the surface on which the cleaner is standing. This will
give added stability when using the attachments. Set the adjustment for
pile height to LOW if using the cleaning tools in an area where there are
bare floors and use SHAG in carpeted areas.
After having followed the steps detailed above you are ready to use your clean-
ing attachments. Simply turn the cleaner switch to the ON position and you
are ready to clean above the floor and all those hard to reach areas in your home.
The handle must be in the upright position for proper, effective use of tools.
