Machine Assembly
1. Locate Assembly Packet - A packet is included with vacuum and includes
two (2) 2-part bolts and two (2) cord hooks. Also included is an extra drive-
belt.
2. Attach Lower / Upper Handle - Slide the upper handle (D) and the lower
handle (E) together so the holes for the handle bolts are aligned and the
slots in the handle are positioned as shown in Figure 2. Insert a 2-part bolt
(A) in the center of the handle and fasten tightly. Position the assembled
handle (D/E) so it curves toward the operator. Push the handle into the
handle socket (F) at the rear of the cleaner. Align the holes, insert the other
2-part bolt (A) and tighten.

3. Attach Upper Cord Hook - Pull the spring (G) on the cord upward toward
the top of the handle. Insert the lower half of the spring (G) into the upper
cord hook (B). Make sure slots in handle are positioned properly (Figure 2).
Place inner tab into slot as shown in (1) and press hook around handle (2),
snapping opposite inner tab into place (3) (Figure 4).
4. Attach Lower Cord Hook - Insert the power cord into the lower cord hook
(C) (Figure 3). Snap the hook into the lower handle. Pull the cord up to tight-
en but leave enough slack near the base so the cord is not strained when
the handle is lowered. Wrap the cord around the two cord hooks. Fasten the
plug to the cord to prevent unwinding.
5. Attach Filter Bag - Position the lter bag adapter clip (H) on the bottom
of the lter bag collar and inside the bag adapter retainer (I) below the air
outlet. Push the bag collar up and forward so the locator tab (J) to the right
of the cam latch (L) slides and engages into the slot (K), then turn the cam
latch to lock the bag onto the shoulder rivet (M). To support the bag, loop
the spring (N) from the top of the bag onto the bag support, located to the
back of the upper cord hook (B) (Figure 2).
Machine Operation
6. Power Switch - The power switch is located at the left rear of machine. Use
foot to step on power switch to turn machine on or o.
7. Handle Adjustment - The handle lock is located at the left rear side of the
machine. Use foot to step on handle lock to release and move handle to
one of three positions.
8. Height Adjustment - This machine has a 6-position carpet height adjust-
ment knob. To select the proper setting, start by moving the knob to the
highest setting. Turn down one setting at a time until the machine’s sound
changes to a smooth buzzing or vibrating tone. This is the sound of the
beater bars grooming the pile. Raising the front of the machine will make it
easier to change settings.
Emptying Cloth Bag - The cloth bag should be emptied frequently for maximum performance. To empty cloth bag,
disconnect power cord from electrical wall outlet. Slide top of bag out of clamp, remove bottom by pulling back on lever
arm on bag collar. Dump contents into a waste container and shake to remove stubborn dust. Reinstall bag on machine.
NOTE: It is not necessary to remove top clamp from machine.
Replacing Disposable Paper Filter Bags (models with zipper bag) - Disconnect power cord from wall
outlet. Unzip the cloth bag and pull the plastic bag throat out of the bag’s top ll sleeve and move coil spring down on
throat. Remove full paper bag and dispose. Slide a new disposable paper lter bag on the plastic bag throat. Move coil
spring up until it stops and paper bag is secure. Zip up cloth bag.
IMPORTANT: For optimum vacuum performance, the disposable paper lter bag should be changed frequently.

receptacle is not available. The temporary adapter should be
used only until a properly grounded outlet (sketch A) can be
installed by a qualied electrician. The green colored ear, lug,
or the like extending from the adapter must be connected to
a permanent ground such as a properly grounded outlet box
cover. Whenever the adapter is used, it must be held in place
