Congratulations,
You now have a REVOLUTIONARY piece of equipment that when coupled with
the PowerBase
™
10 or PowerBase
™
5, incorporates the latest in Chem-Dry carpet
cleaning technology. The Chem-Dry PowerHead AX
™
features are designed to increase
the productivity of you the user, your Technicians and business, while decreasing the
fatigue factor. With competition as strong as it is, you have not only invested in a
specialized cleaning tool, but also a marketing tool that will enhance your professional
image and the Chem-Dry brand.
Your foresight in acquiring and using Chem-Dry’s patented “Hot Carbonating
Extraction” technology will be rewarded with the knowledge that you are providing your
customers with maximum cleaning effectiveness and the best cleaning process Chem-Dry
has to offer. Using the Chem-Dry PowerHead AX
™
will also enhance your Technicians
image as professional carpet cleaning operators, rather than professional laborers.
Once again, congratulations for acquiring the Chem-Dry PowerHead AX
™
and
being an industry leader. Now more than ever, the competition will have to do that much
more to compete with you!
An Evolution That Had To Happen
Your new Chem-Dry PowerHead AX
™
has been precision engineered to bring
you state-of-the-art in carpet cleaning. In the past, a wand-using Technician had to supply
all the pressure and motion when cleaning carpets. The weight distribution and rotary
motion enables the Technician to maneuver the Chem-Dry PowerHead AX
™
unit easily
with less fatigue and back strain.
The electric motor of the Chem-Dry PowerHead AX
™
drives a precision transmission
that, in turn, rotates the Amplified Extraction cleaning head assembly. “The Natural®” III
cleaning solution is injected through the center of the stainless steel gearbox shaft directly
to the five spray jets. Soiled solution is then extracted from the carpet by five Chem-Dry
exclusive patented extraction cleaning heads and drawn through the aluminum exhaust
manifold to the “Hot Carbonating Extraction” unit recovery tank.
Construction
The base, manifolds, handle, gearbox housing, and cleaning heads are all cast or
molded aluminum. Other parts are either made of metal, stainless steel or high impact
plastic.

Assembly Instructions
To prepare your machine for use, follow these instructions:
a) Remove the machine from the packaging. Inspect the machine carefully
for any damage that may have occurred during shipping. If any oil spillage
is noted, be sure to check the gearbox lubricant level (see instructions).
b) Now, attach the cleaning head to the base. Lean the machine back and rest
it on the handle. Thread the cleaning head onto the exposed shaft
remembering to go in a counterclockwise direction (left-handed threads).
Important: Remove the gearbox cover and replace the solid shipping plug from
the top of the gearbox with the vented plug provided before operating the
machine. Reattach the cover back onto the Chem-Dry PowerHead AX
™
.
Your machine is now ready to operate.

Operation
Preparation
1. Handle Adjustment: Push the
clamp forward to loosen the
linkage. Adjust the handle to a
comfortable height. Pull clamp
back to lock in place.
NOTE: Most Technicians have found
better control and less fatigue when the
handle is in a low position-- just around
the hip line. There is an ideal position
for each person that will ensure the
Chem-Dry PowerHead AX
™
will do the
work for you.
2. Solution and Vacuum Hose
Hook-Ups: Your Chem-Dry
PowerHead AX
™
is equipped
with two 440 S/S male quick
connects for the dual solution
hose and a 37mm (1½in) vacuum
hose inlet. (refer to the above
photo) It also has a dual solution
hose with the two 440 female
quick connects is required. The
vacuum inlet requires a 37mm
(1½in) I.D., and a 50mm (2in)
O.D. vacuum hose for proper air
flow.
IMPORTANT: The vacuum hose must
be in good condition to ensure maximum
airflow.
3. Electrical Cord Hook-Up: The
15 meter (50ft) electrical cord on
your Chem-Dry PowerHead
AX
™
is a male/female three-
prong IEC plug. Attach the
female end to the receptacle on
the handle. The male end must be
attached to a small lead fitted
with the appropriate plug. This is
not supplied by CDNS.
¨ CAUTION ¨
Do not, under any circumstances,
remove the ground prong from your
Chem-Dry PowerHead AX
™
power
cord. Serious injury or death may
result.
Operating Instructions
1. Control Functions: There are
control triggers located on each
side of the handle under the
rubber handgrips. As you operate
the Chem-Dry PowerHead AX
™
,
the trigger on your right-hand
side controls the electric motor
that drives the Amplified
Extraction cleaning heads. The
Safety switch located on the top
of the handle must be depressed
while the trigger is pulled. Once
the motor is running, the safety
switch can be released. This must
be done each time the trigger is
released and the motor is
restarted.

Chem-Dry PowerHead AX
™

This lockout will prevent accidental
starting of the motor. On the left-
hand side, the trigger controls the
low pressure Hot Carbonating
solution spray. The air flows
constantly while the Chem-Dry
PowerHead AX
™
is in operation.
2. Maneuvering Your Chem-Dry
PowerHead AX
™
:Your Chem-
Dry PowerHead AX
™
maneuvers
like a buffer. To move to the
right, lift the handle slightly. The
more you lift or lower the handle,
the faster the machine will move.
To move forward and backward,
position the handle so that the
unit remains stationary, then
push forward or pull back. To
familiarize yourself with your
Chem-Dry PowerHead AX
™
,
practice on an open carpeted
area. Depress both the solution
trigger and motor trigger and
move the machine slowly in a
one to two meter (3 to 5 ft) arc,
as shown in Cleaning Patterns
on the following page.
¨ CAUTION ¨
Do not operate your PowerHead on dry
Carpets as the friction generated by the
revolving Amplified Extraction cleaning
heads may damage fibers in the carpet.
Once you have become familiar with the
speed and movement of the machine,
practice making it hover in one spot.
The hovering maneuver is useful for
removing stubborn stains, as well as
removing furniture indentations.
Do not tilt machine sideways while
moving forward and backward. A loss of
control may result in damage to the unit
or location.
3. Using the Crevice Tool:
The crevice tool is located on the
front right-hand side of the Chem-Dry
PowerHead AX
™
. To remove, pull the
crevice tool upward until the alignment
pin matches the large diameter of the
keyhole slot. Pull the tool away from
the unit and it is ready to use. When
attaching it back onto the machine, rest
the end of the tool on the lower elbow
and slide the pin into the keyhole slot.
Gently push the crevice tool into the
elbow until it is snug.

Cleaning
Information
Cleaning Patterns
For regular carpet cleaning, use an
overlapping arc pattern, two times over
the same area (one pass with solution
and one pass for drying). When cleaning
carpets, first clean in a circular pattern,
then use the overlapping arc pattern to
dry the area.
Note: Dirtiest areas may require two or
more cleaning passes. Using either
pattern, you should develop a
comfortable rhythm. To obtain
maximum performance from your
Chem-Dry PowerHead AX
™
, move it
slowly and deliberately with a 50%
overlap, giving it time to clean and
extract. (Unlike a manhandling wand,
the unit is doing the work your
Technician had to do in the past) A
steady pace rather than a frenzied one
will increase efficiency and production
and decrease fatigue.
The Following Cautions
Should Be Observed While
Cleaning:
1. DO NOT operate your Chem-
Dry PowerHead AX
™
over metal
floor moldings as damage to both
the molding and the Amplified
Extraction cleaning head will
result.
2. DO NOT operate your Chem-
Dry PowerHead AX
™
on
hardwood floors.
3. DO NOT operate your Chem-
Dry PowerHead AX
™
over loose
or unraveled carpet seams. The
Amplified Extraction cleaning
head may catch and cause further
damage.
4. DO NOT operate your Chem-
Dry PowerHead AX
™
on
concrete floors. It will develop
sharp edges on the Amplified
Extraction heads that will
damage carpet fibers.
5. DO NOT clean over the edge of
a loose carpet. Instead, clean
only up to the edge. Damage
may occur should the Amplified
Extraction heads catch the loose
carpet.
Special Information:
During the cleaning of some plush
carpets, you may notice a “pilling”
effect. With the Chem-Dry PowerHead
AX
™
, loose yarns form balls and are
kicked aside as the Amplified Extraction
cleaning heads revolve. This is normal
when aggressive cleaning or even
normal vacuuming takes place, as
evidenced by a number of dead, loose
yarns in the vacuum cleaner bag. These
loose yarns, in most cases, are short
staple yarns or filler yarns used to give
the carpet a denser appearance. Because
your Chem-Dry PowerHead AX
™
weighs approximately 31 kilograms (70

Chem-Dry PowerHead AX
™
Rev: # 1 Jun 2002
PGS
7
lbs) and rests on five 100mm (4 in)
cleaning heads, the yarns are not sucked
up into the Amplified Extraction heads
as they are with a vacuum cleaner or old-
style cleaning wand.
¨ CAUTION ¨
The Chem-Dry PowerHead AX
™
may
cause further damage to older, rubber-
backed, glued down carpets that may be
delaminating with age. When in doubt,
DO NOT use your Chem-Dry
PowerHead AX
™
.
Cleaning Hints
A. Most cleaners customarily clean
their way out of an area or room.
With the Chem-Dry PowerHead
AX
™
, it is possible to clean into
an area or room, as shown in the
illustration below, so that the
hoses are dragged behind you
during the cleaning process
rather than kicked out of the way
as you back out of an area. The
“cleaning into” method works
especially well in hallways or
confined areas.
B. The Chem-Dry PowerHead AX
™
is a very aggressive carpet-
cleaning machine and will leave
the carpet with a freshly cleaned
appearance. The carpet should be
brushed or groomed after the
cleaning process to remove any
swirl marks left behind.
The Chem-Dry PowerHead AX
™
has
been very successful in restoring badly
matted traffic lanes in front of doorways
and sofas. Even pivot areas can be
brought back to life again, in most cases.
“Cornrowing” in hallways can also be
eliminated with minimal effort.

Machine
Maintenance
Good care and regular maintenance of
your Chem-Dry PowerHead AX
™
will
result in a long, dependable life for the
unit. Keep in mind that your Chem-Dry
PowerHead AX
™
will be in full view of
your customer. A Chem-Dry
PowerHead AX
™
that is dirty and
unkempt in appearance can cause your
image to suffer. You are offering your
customer the latest in cleaning
technology. Therefore, it is important
that your company image reflect your
desire to give your customer THE
BEST.
The surface finish on your Chem-Dry
PowerHead AX
™
is a durable, baked on
epoxy coating and is easily cleaned with
a damp cloth. To further protect the
finish, a light coat of good silicon base
polish should be applied periodically.
Lubrication and maintenance play a key
role in the life of your Chem-Dry
PowerHead AX
™
. Hence, the following
daily and periodic maintenance steps
must be followed. Train yourself to
maintain your unit on a regular schedule
until it becomes habitual.
Daily Maintenance
1. Inspect the power cord for cuts,
breaks, etc. Repair as needed.
2. Inspect the vacuum hoses for
breaks or tears. Repair or replace
as necessary.
3. Visually inspect your Chem-Dry
PowerHead AX
™
for water leaks,
damage to the Amplified
Extraction cleaning heads, etc.
Repair as necessary.
4. Check the jet spray for evenness.
An uneven spray will cause
improper flow of the cleaning
solution.
5. Remove the Amplified
Extraction cleaning head. It
unscrews in the same direction it
turns during operation (or
clockwise when looking at it
from the underside). Once you
have loosened the assembly, spin
it off with your hands. If the
cleaning head is difficult to
remove, you may use a ¾ inch
socket wrench on the exposed
center nut located under the
gearbox cover. To prevent the
gearbox from turning, remove
the gearbox cover to expose the
output shaft.
The output shaft will accept a 5/8

Chem-Dry PowerHead AX
™
Rev: # 1 Jun 2002
PGS
9
inch wrench just below the rotary
union. Wash the cleaning heads
and shroud assembly with a
garden hose, being careful not to
wet the electric motor assembly.
Clean any lint buildup from the
cleaning heads and vacuum hoses
(lint buildup will restrict proper
air flow and prolong drying
time). Before cleaning the
cleaning head assembly, place
the rubber stopper (available in
the Service Kit, Part No. E2000-
SK) inside the threaded bore of
the hub. This will prevent debris
from entering the solution lines
and clogging the spray jets.
¨ CAUTION ¨
6. Clean off any debris that may
have accumulated on the gearbox
shaft or the inside threaded bore
of the hub. An accumulation of
debris here, if not removed, may
damage the gearbox oil seal.
This will result in loss of oil in
the gearbox. If the gearbox is
operated without oil, severe
damage may occur.
7. Lubricate the felt vacuum seal on
top of the hub with a quality, 30
weight SAE motor oil. Also, it
pays to put a few drops into the
hub threads.
8. Coat the shaft with Pennz-Guard
or a similar lubricant. Reinstall
the vacuum head assembly onto
the shaft by rotating it counter-
clock-wise.
IMPORTANT: While rotating the
vacuum head assembly in the counter
clockwise position, make sure that it
spins freely all the way down. If it
begins to require the slightest fingertip
pressure, unscrew it and brush off the
threads. All it takes is the slightest grain
of dirt or sand to obstruct the threads. If
you turn too far onto a grain of dirt, the
hub may become locked onto the shaft
of the gearbox.

Periodic Maintenance
Check the oil level in the gearbox on a
monthly basis. This is a permanently
lubricated gearbox. You do not need to
change the oil. However, maintaining
the proper oil level is important. To
check the oil level, remove the vent plug
and look into the gearbox. Turn the
cleaning head until you can see the
inspection hole in the gear. With the
PowerHead sitting flat on a table or the
floor, the oil level should be up to, but
not above, the middle of the gear. If oil
needs to be added, use quality 80-90-
weight gear oil.
NOTE: When checking the oil level in
the gearbox, you can use a toothpick as a
dipstick. The oil level should read 9mm
(3/8 in).
Transport and/or Storage
Whenever your Chem-Dry PowerHead
AX
™
is transported or stored, it is
recommended that the cleaning head be
removed. The machine will then sit flat
on the floor and remain more stable,
especially during transport.
Freeze Warning/Protection
Your Chem-Dry PowerHead AX
™
can
sustain damage from freezing, as can
any equipment that functions with the
use of water. Care must be taken to
protect this tool from freezing just as
you do your other equipment. To protect
it from freezing, simply blow air from a
gas station air hose through the solution
quick connect with the valve open.
This will blow all water from the valve,
solution line, rotary union and jet
assembly. Open and close the valve
several times to ensure that all water is
removed.
