Safety Instructions
Owner’s Responsibility
To maintain machine and user safety, the responsi-
bility of the owner is to read and follow these instruc-
tions:
•Follow all installation instructions.
•Make sure installation conforms to all applicable
Local, State, and Federal Codes, Rules, and
Regulations; such as State and Federal OSHA
Regulations and Electrical Codes.
•Carefully check the unit for correct initial function.
•Read and follow the safety instructions. Keep them
readily available for machine operators.
•Make certain all operators are properly trained,
know how to safely and correctly operate the unit,
and are properly supervised.
•Allow unit operation only with all parts in place
and operating safely.
•Carefully inspect the unit on a regular basis and
perform all maintenance as required.
•Service and maintain the unit only with authorized
or approved replacement parts.
•Keep all instructions permanently with the unit and
all decals/labels/notices on the unit clean and
visible.
•Do not override safety features.
Operator Protective Equipment
Personal protective equipment helps make tire ser-
vicing safer. However, equipment does not take the
place of safe operating practices. Always wear dura-
ble work clothing during tire service activity. Loose
fitting clothing should be avoided. Tight fitting leather
gloves are recommended to protect operator’s hands
when handling worn tires and wheels. Sturdy leather
work shoes with steel toes and oil resistant soles should
be used by tire service personnel to help prevent injury
in typical shop activities. Eye protection is essential
during tire service activity. Safety glasses with side
shields, goggles, or face shields are acceptable. Back
belts provide support during lifting activities and are
also helpful in providing operator protection. Con-
sideration should also be given to the use of hearing
protection if tire service activity is performed in an
enclosed area, or if noise levels are high.

Make sure the instruction and warning decal
is clean and clearly visible to operator.
Remember R.I.M.
Three Simple Steps To Help Keep Shops Safe
R.I.M. is a training program developed by Hennessy
Industries to help keep tire technicians safe. By fol-
lowing the basic principles of R.I.M., technicians can
avoid situations that can cause catastrophic accidents
like tire explosions.
R.I.M. stands for read, inspect, and mount:
Read the tire size on a new tire before mounting to
make sure it is the proper size for the wheel.
Inspect the wheel for cracks, rust, and or other dam-
age that could cause an unsafe situation.
Mount the tire safely, making sure not to put any part
of your body over the tire during inflation.
The most serious of possible accidents is a tire explo-
sion. This is often caused by a tire/rim mismatch.
If a tire explodes on a tire changer, pressure causes it
to fly straight up at tremendous speed. If a technician
is standing over the tire, he can be seriously injured
or killed.
READ INSPECT MOUNT

Operation Instructions
This unit must be properly operated and properly
maintained to help avoid accidents that could dam-
age the unit and injure the operator or bystanders.
This section of the Operation Instructions manual
reviews the basic operations and use of controls.
These instructions should be reviewed with all employ-
ees before they are allowed to work with the machine.
Keep these instructions near the machine for easy
reference.
Bead Loosening and Demounting
CAUTION
This machine may operate dierently from
machines you have previously operated.
Practice with a regular steel wheel and tire
combination to familiarize yourself with the
machine’s operation and function.
Remember to remove all weights from both
sides of the wheel. Weights left on backside of
wheel may cause the wheel to be clamped
unleveled. This may result in the Duckhead®
mount/demount tool contacting the rim caus-
ing scratches. On alloy wheels, always rotate
the wheel one turn after setting the mount/
demount tool to insure proper wheel chucking.
Always review with the owner any nicks and
scratches on expensive wheel and tire combi-
nations prior to servicing.
CAUTION
Loosening the beads on a partially or fully
inflated tire is unsafe and causes excess
movement and friction against the bumper
pads and excessive wear on pivots. Deflate
the tire completely to prolong the life of your
machine.
1. Deflate the tire completely by removing the valve
core from the valve stem (figure 4). Be cautious and
do not smoke as a flammable gas could have been
introduced into the tire at some time.
Figure 4 - Remove Valve Core to Deflate Tire
CAUTION
Tires are always installed and removed from
the rim’s narrow side.
Always loosen the bead on the narrow side of
the wheel’s drop center first (tire removed in
figure 5 for clarity).
Figure 5 - Determine Narrow Side of Wheel
The clamps on the table top may extend
beyond the table top itself. To avoid damaging
the clamps, move them to their full inward
position before positioning a tire for bead
loosening.
Use extra care in positioning the bead loosener
shoe on larger wheels/tires, and on alloy
wheels. Make sure the shoe rests next to but
not on the rim, and not on the tire sidewall.
2. Pull the bead loosener shoe away from the
machine and roll wheel into position. The valve stem
should be in the 2 o’clock position to accommodate a
possible asymmetric safety hump type rim. Position
the bead loosener shoe against the tire next to, but
not on, the rim. Press the bead loosener foot pedal to
actuate the shoe and loosen the bead. It may be nec-
essary to loosen the bead in multiple locations around
the tire (figure 6).

Important: Always read and follow operating instructions. • 9

3. Turn the wheel around and repeat loosening pro-
cedure on the other side of the wheel (figure 7). This
should be the long side of the drop center (figure 5).
Figure 7 - Position Tire and Bead Loosener Shoe With Wheel
Turned Around
It will be easier to outside clamp the wheel to
the table top if the long side of the rim is loos-
ened last.
4. Apply tire manufacturer’s approved rubber lubri-
cant liberally to entire circumference of both tire
beads after loosening (figure 8).
Figure 8 - Apply Rubber Lubricant to Tire Beads
5. Determine the mounting side of the wheel. The
mounting side is the narrow side of the drop center.
See figure 2 for more information on the drop center.
6. Place tire/wheel assembly on table top with
mounting side up (figure 9). Use the clamp control
pedal to move the clamps inward (push pedal down)
or outward (toggle pedal up). Clamp steel wheels
from the inside (clamps push outward against wheel).
Clamp mag and custom wheels from the outside
(clamps push inward against the outside rim edge).
Figure 9 - Place Tire/Wheel Assembly on Table top
7. Move the swing arm into position. Pull the locking
handle forward to release the slide. Push down on the
top of the vertical slide to move the mount/demount
tool into contact with the rim edge. Push the locking
handle back and lock the slide into place (figure 10).

the rim edge. Turn the swing arm adjusting knob to
move the mount/demount tool away from the rim 1/8
to 1/4 inch (figure 11)
Figure 11 - Adjust Swing Arm to Position Tool Roller
9. Check metal mount/demount tool positioning.
The metal mount/demount tool should be positioned
with 3/16 to 1/8 inch clearance between the top of the
rim edge and the bot-tom of the tool, and 1/8 to 1/4
inch clearance between the rim edge and the mount/
demount tool roller. This clearance will be maintained
as long as the locking handle and adjustment knob
are not changed. The operator may swing the arm out
of the way and back into place again without need-
ing to reposition the tool (when changing a like set of
wheels) (figure 12).
Figure 12 - Proper (Metal) Mount/Demount Tool Position
The tool clearance may change with machine
use and should be inspected often. Failure to
maintain the proper clearance may result in
damage to the wheel rim and/or tire.
Normal table top rotation for demounting is
clockwise. Depress the table top pedal to rotate
this direction. To rotate the table top counter-
clockwise, lift the pedal up with your toe.
Table top rotation can be stopped at any time
by removing your foot from the rotation pedal.
CAUTION
At times during the mounting and demounting
procedure, the bead lifting tool may encoun-
ter resistance and can be thrown. Keep one
hand firmly on the tool to avoid possible tool
disconnect. Use the reversing feature to back
out of jam-ups. A thrown tool can cause injury.
10. Insert the smooth curved end of the bead lifting
tool over the forward end of the mount/demount tool
and below the top bead of the tire. Lift the bead up
and over the knob on the Duckhead®mount/demount
tool (figure 13). Also, note the valve stem position to
the mount/demount tool. Use your free hand to press
down on the tire opposite the mount/demount tool to
allow the bead to utilize the drop center area of the
rim, this position reduces stresses in the bead and
allows an easier bead lift.
Figure 13 - Insert Bead Lifting Tool Below Tire Bead

Important: Always read and follow operating instructions. • 11
11. Push the bead lifting tool down towards the wheel
to lift the tire bead up and over the knob portion of the
mount/demount tool. Hold the bead lifting tool and
tire bead in this position (figure 14).
Figure 14 - Lift Tire Bead Over Duckhead®Mount/Demount
Tool Knob
12. Depress the table top pedal to rotate the wheel.
The Duckhead®mount/demount tool will guide the
tire bead up and over the edge of the wheel. Continue
rotation until the upper bead is demounted.
Push down on the tire across from the mount/
demount tool during table top rotation to utilize
the drop center area of the wheel. This reduces
the tensional force on the top or first bead
during demount (figure 13).
Figure 15 - Demounting Lower Bead
13. Lift and hold the tire at an angle so that the
lower bead is resting in the drop center directly across
from the mount/demount tool, and is loose below the
mount/demount tool (figure 15). Insert the smooth
curved end of the bead lifting tool down over the for-
ward end of the mount/demount tool and below the
lower bead. Lift the bead up and over the knob on the
mount/demount tool (figure 16).
Figure 16 - Guide Lower Bead Over Tool Knob
14. Depress the table top pedal to rotate the wheel.
The mount/demount tool will guide the bead up and
over the edge of the wheel. Continue rotation until
lower bead is demounted.
With tube-type tires, demount the upper bead
and remove the tube before demounting the
lower bead.

12 • Important: Always read and follow operating instructions.
Mounting
This information must be read and followed carefully
to prevent accidents and injuries during mounting.
Attempts to force a bead seat on mismatched
tires and wheels can cause the tire to violently
explode, causing serious personal injury or
death to operator and/or bystanders.
Check tire and wheel carefully before mount-
ing. Make sure the tire bead diameter and
wheel diameter match exactly. Consult the
Tire Guide and/or Rubber Manufacturer’s
Association for approved rim widths for tire
sizes.
Never mount a damaged tire. Never mount a
tire on a rusty or damaged wheel. Damaged
tires and/or wheels may explode.
CAUTION
When in doubt do not mount.
CAUTION
Never mount a tire and wheel handed to you
by anyone without checking both tire and
wheel for damage and to be certain the sizes
match. Do not let untrained persons operate
tire changer and keep bystanders out of ser-
vice area.
CAUTION
Forcing the tire onto the rim can cause bead
damage. If you damage the tire bead during
mounting, STOP!, remove tire and mark it as
damaged. Do not mount a damaged tire.
1. Before any mounting, inspect tire for damage and
verify size match between tire and wheel (figure 17).
Figure 17 - Verify Size Match Between Tire and Wheel
2. Inspect wheel closely for damage. Clean the
wheel and remove any light corrosion or rubber resi-
due (figure 18). Do not attempt to service a heavily
corroded wheel, damaged wheel, or bent wheel.
Figure 18 - Inspect and Clean the Wheel
3. Inspect valve stem and replace if necessary. Next
lubricate tire beads liberally with tire manufacturer’s
approved rubber lubricant (figure 19).
Figure 19 - Lubricate Tire Beads Liberally

Important: Always read and follow operating instructions. • 13
4. Place tire over wheel and move swing arm into
position making sure the valve stem is at the 9 o’clock
position in front of bead lock. Position tire so that
lower bead is above the rear extension of the mount/
demount tool and below the front knob (figure 20).
Figure 20 - Position Tire Against Mount/Demount Tool
5. Depress table top pedal and rotate wheel to
mount lower bead. Use drop center of wheel by forc-
ing down on tire just ahead of the mounting tool, and
follow as tire rotates. Rotate table top until lower bead
is mounted.
6. For top bead installation, rotate the table top until
the valve stem is directly across from the Duckhead®
mount/demount tool. Lift the upper bead up and
over the rear of the mount/demount tool. With your
left hand press down on the tire between the mount/
demount tool and the valve stem, to hold the tire in the
drop center. Depress table top pedal and rotate tire
until bead is mounted. Be careful to ensure bead stays
in the rim drop center in the area ahead of mount/
demount tool (figure 21).
Figure 21 - Mounting Top Bead
If table top rotation stalls, reverse the table top
momentarily until tire bead is again loose on
the wheel. Reposition tire on Duckhead®
mount/demount tool, make sure bead is cor-
rectly positioned in drop center of the wheel;
then attempt mounting again.
For low profile or sti sidewall tires, it may be
advantageous to use the bead lifting tool to
initially hold the upper bead down in the drop
center.
For tube type tires, mount lower bead first,
move swing arm out, install tube, and then
mount upper bead.

14 • Important: Always read and follow operating instructions.

Inflation Pedal Positions
Ination
Tire inflation is performed in three steps: BEAD
SEAL, BEAD SEAT, and INFLATION. These steps are
explained in detail on page 18. Read the explanation
of each step and understand them thoroughly before
proceeding.
Tire failure under pressure is hazardous. This
tire changer Will Not Restrain Exploding Tires,
rims or other related equipment. Inspect tire
and wheel carefully for match, wear, dam-
age, or defects before mounting. Always use
approved tire bead lubricant during mounting
and inflation.
CAUTION
The clip-on chuck allows the operator to keep
hands and entire body back from inflating
tire. The chuck must be an open/freeflow
style with all parts in proper working order.
CAUTION
Check for proper inflation gauge operation.
Accurate pressure readings are important
to safe tire inflation. Refer to the Operat-
ing Maintenance section of this manual for
instructions.
CAUTION
If the rim has been clamped from the outside
for tire mounting, release the clamps, lift the
tire, and move the clamps to the center of the
table top.
CAUTION
If the wheel/tire has a diameter larger than
14-inches and is dicult to bead seal, the
clamps should be moved to the center of the
table top for the bead seal operation.
The inflation pedal, located at the rear of the left side
of the machine, controls the flow of air through the
inflation hose, and has three positions.
The clip-on chuck on the end of the hose
should always be an open/freeflow style with
all parts in proper working order.
Position 1 - Tire Pressure – With the inflation
hose attached to the tire valve and the pedal in this
position, the air gauge will register the air pressure
in the tire. Whenever your foot is removed from the
pedal, it will return to this position.
Position 2 - Tire Ination – This is the first acti-
vated position. With the inflation hose attached to the
tire valve and the pedal in this position, line pressure is
allowed to flow through the valve system and into the
tire for inflation. Correct tire pressure is not indicated
on the gauge in this position.
Position 3 - Bead Sealing – This is the second
and last activated position. With the inflation hose
attached to the tire valve and the pedal in this posi-
tion, line pressure is allowed to flow through the valve
and to the air-flate bead seal jets on the table top for
bead sealing.
1. If the rim has been clamped from the outside for
tire mounting, release the clamps, lift the tire, and
move the clamps to the center of the table top.
Note the Inflation Pedal Positions (See Above)

Important: Always read and follow operating instructions. • 15
CAUTION
Use of bead sealing jets without a tire in place
can cause dirt and debris to be blown into the
air with enough force to injure operator and/
or bystander. Do not use the bead sealing
control position to inflate a tire.
This unit is equipped with a pressure regulator
to assist the operator with proper tire inflation.
The pressure regulator will keep most car and
light truck tires from inflating beyond 60 PSI
(smaller tires may reach higher pressures). It is the
operator’s responsibility to follow all instructions
and to control inflation pressure as specified in
these instructions. Check the function of the pres-
sure regulator regularly and maintain it according
to the instructions provided in this manual for safe
and proper operation. Do not tamper with or
attempt to adjust the pressure regulator. Tires
requiring inflation beyond 60 PSI should be
inflated in a safety cage.
Bead Sealing
1. Remove the valve core from the valve stem to allow
more air flow into the tire to assist with bead seal.
2. Position valve stem in front of operator and con-
nect the inflation hose with the clip-on chuck. Hold
tire up against upper edge of the wheel. Be sure tire’s
top bead does not cover the bottom of the valve stem
(figure 22).
Figure 22 - Lift Tire Upwards for Bead Sealing
3. Depress inflation pedal to position 2 and hold
about one second to begin air flow through tire valve,
then depress pedal to position 3 and hold briefly —
less than one full second. The blast of air from the jets
will expand tire and seal the beads.
4. Release the inflation pedal and allow it to return
to position 1. Verify that both beads are completely
sealed to the wheel. Repeat these steps if beads have
not sealed. It may be necessary to wait a few seconds
for the air storage tank pressure to recover before
attempting again.
5. After bead seal is achieved, remove the clip-on
chuck and reinstall the valve core. Reattach the clip-
on chuck after core is installed.

Bead Seating
NEVER exceed 40 PSI to seat beads while
using this tire changer. If more than 40 PSI is
permitted by tire manufacturer, ALWAYS use
safety cage and clip-on chuck. NEVER exceed
recommended pressure after seating beads.
ALWAYS keep hands and entire body back
from inflating tire.
An exploding tire, wheel, or bead sealing
equipment may propel upward and outward
with sucient force to cause serious injury or
death to operator or bystander.
Check tire pressure frequently. If operator
is unable to obtain bead seat, something is
wrong. Deflate tire completely, inspect tire
and wheel, correct any problems found, re-
lubricate both tire beads, and reattempt bead
seal and seat procedures. Follow all safety
instructions in this manual and on machine.
1. Once tire pressure is indicated on the air gauge
(inflation pedal in position 1; foot removed from
pedal), continue to inject air into the tire (inflation
pedal position 2) in short intervals. Check the pressure
frequently. Stand back during bead seat. Keep hands,
arms, and entire body away from tire during this pro-
cedure (figure 23).
Tire beads should move outward and “pop” into
their bead seat position as pressure inside the tire
increases. If this does not happen, a problem exists.
Investigate carefully.

Inflation
NEVER exceed tire manufacturer’s recom-
mended air pressure. Tires can explode,
especially if inflated beyond these limits.
Use clip-on air chuck, keep hands, arms and
entire body back from inflating tire. Avoid
distraction during inflation. Check tire pres-
sure frequently to avoid over inflation. Exces-
sive pressure can cause tires to explode,
causing serious injury or death to operator or
bystander.
1. Make sure both beads are seated. When both
beads are seated, the tire is ready for inflation.
2. Replace the valve core if it was removed.
3. Depress the inflation pedal to position 2 to inflate
the tire. On most tires, the pressure regulator will
cease air flow at approximately 60 PSI. On smaller
volume tires the pressure may be higher.
4. Important: When inflating tires that require more
than 60 PSI, always use a safety cage and air hose
with a clip-on air chuck and in-line valve. The air hose
must have enough length between the chuck and the
operation/in-line valve to allow the operator to stand
outside the trajectory.
If you change tires defined as truck tires, they
must be inflated per OSHA instructions.

Explosion Hazard
Never exceed 40 PSI
while seating beads.
Remember R.I.M.
(see page 3 and back cover)
Explosion Hazard
Never inflate tire
above manufacturer’s
recommended pressure
after bead is seated.

Stages of Ination on a
Conventional Tire and Rim
Review these descriptions and diagrams carefully. Refer to them as
necessary during bead sealing, bead seating, and inflation to verify that
you are proceeding properly and safely.
Bead Sealing
Bead sealing is the process of capturing air pressure between the tire
and the rim. The tire will usually contain about 1/2 to 2 PSI at initial bead
seal.
Bead Seating
Bead seating usually occurs on the long tapered side of the wheel first
and the shorter side last. Bead seating will usually require at least 7 PSI
in the tire. 40 PSI is the maximum safe pressure at this stage regardless
of tire operating pressure.
Most European import cars and many aftermarket alloy wheels are
very tight and can be dicult to bead seat. Also note that asymmetrical
hump and run-flat tires are extremely dicult to bead seat. Follow tire
manufacturer’s recommended procedure for bead seating.
Inflation
After the beads are seated, the tire is ready to be inflated. Do not
inflate the tire above the manufacturer’s recommended pressure as
stamped on the tire sidewall. The typical inflation pressure for automo-
bile tires is between 24 and 45 PSI. Light truck inflation pressure typi-
cally covers a wider range.
