Safety
Failure to follow danger, warning, and caution
instructions may lead to serious personal injury or
death to operator or bystander or damage to prop-
erty. Do not operate this machine until you read
and understand all the dangers, warnings and cau-
tions in this manual. For additional copies of either,

Operator Protective
Equipment
Personal protective equipment helps make tire serv-
icing safer. However, equipment does not take the
place of safe operating practices. Always wear durable
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 dur-
ing 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.
Consideration should also be given to the use of hear-
ing protection if tire service activity is performed in an
enclosed area, or if noise levels are high.

core to deflate the tire before servicing.
ALWAYS cover the electric motor and switch box
before hosing down the tire changer. Be sure water
does not enter the motor or switch box.
ALWAYS disconnect the electric power and air sup-
ply before attempting any maintenance.
ALWAYS keep all working surfaces clean and free of
tire lube buildup.
ALWAYS be aware of what each person is and will do
before attempting any two-person operation.
Bead Loosening
NEVER place anything between the bead loosener
disc and the tire/wheel.
NEVER place any part of your body between the
bead loosener disc and the tire/wheel, severe bodily
injury may result.
NEVER allow the bead loosener to contact the

H.I.T. 5000H2
Installation
It is not necessary to bolt the H.I.T. 5000H2 to the
floor. However, if desired, use the holes provided in
the base of the machine.
Most electrical codes require machinery
that is permanently installed to be wired
directly to the power source via conduit.
Remove the H.I.T. 5000H2 from the shipping pallet
and position on a relatively level and smooth floor,
preferably concrete.
Important: Read this operators manual thoroughly
before attempting to change any tires. Also, actuate
the controls several times to become familiar with
their function and direction.
Electric Installation
The H.I.T. 5000H2 requires 220 volts, 60 cycle, single
phase power, with a 20 amp circuit. An optional model
is available for 110 volt, single phase.
Important: Have a licensed electrician connect the
H.I.T. 5000H2 to the power source. The licensed elec-
trician must sign the warranty registration card to val-
idate the warranty.

Wheel Clamping
The self-centering chuck is powered by the high pres-
sure hydraulic system to securely lock onto the wheel.
Important: The hydraulic pressure regulator knob,
located on the swinging pod front, should normally be
set to 1500 PSI. This pressure should be reduced when
mounting or demounting weak or light weight wheels.
1. Roll the wheel onto the platform with the drop
center (or the split ring) away from the chuck. Position
the valve stem between two of the jaw clamps so the
stem will not be damaged when the wheel is clamped.
2. Rotate the chuck until one of the jaw clamps is in
the 12 o'clock position.
3. Open the jaw clamps slightly larger than the open-
ing you are clamping, then move the jaw clamps up or
down to the approximate center of the wheel. Refer to
the wheel drawings on this page for suggested meth-
ods of clamping various types of wheels.
4. Lower the jaw clamps until you can position the
wheel on the top jaw clamp. Raise the chuck, which
will also raise the wheel off the platform.
5. Slowly retract the jaw clamps until the wheel falls
into the proper position for clamping. Clamp the wheel
by pulling the control lever toward you until the
hydraulic motor stalls. Release the handle and the
wheel is ready for mounting or demounting.

Bead Loosening
1. After locking the wheel on the chuck, remove the
valve core and deflate the tire completely.
2. Position the bead loosening disc in one of the
square holes in the carriage closest to the outer edge
of the tire.
3. Rotate the tire. While the tire is rotating, slowly
advance the bead loosening disc to contact the tire
bead. Adjust the chuck up or down so the disc is close
to the rim.
Do not contact the rim with the bead loos-
ening disc. Damage to the rim may result.
4. Once the rim edge is cleared, the chuck may be
lowered to move the disc closer to the tire bead.
Continue moving the disc toward the machine until the
bead is loosened.
5. While the tire is still rotating, apply a liberal
amount of tire lubricant to the tire bead and the rim.
6. Raise the chuck and back the tool away from the
tire, being careful not to contact the rim.
7. Move the bead loosening disc to the rear of the
tire and repeat the steps above to loosen the rear
bead.
Note: Tire lubricant is very important in the demount-
ing and mounting process. While the bead loosening
tool is pushing the bead away from the rim edge, lib-
erally lube both beads and the rim. FAILURE TO APPLY
LUBE COULD RESULT IN DAMAGE TO THE TIRE
BEAD.
Note: Applying a liberal amount of lube to the tire
sidewall prior to bead loosening will make the tire
more pliable and therefore reduce the likelihood of
damage to the sidewall.
Demounting
1. If the rim has an inclined edge of 15 degrees, con-
tinue the bead loosening procedure for the rear bead
until the tire has been pushed off the rim.
The bead opposite the disc must be in the
drop center of the rim. Damage to the bead
may occur if the bead is not in the drop cen-
ter.
2. If the rim has no edge, or has a stiff sidewall,
retract the disc and remove it from the carriage. Place
the combo tool and tee into position near the outer rim
edge.
CAUTION
CAUTION
Tubeless, Duplex, and Supersingle Tires

3. Tighten the locking handle and move the tool into
position near the edge of the rim, as shown above.
4. Insert the bead lifting tool between the rim and
bead at a point near the right side of the tool.
5. Pry the bead out over the rim.
Note: You may have
to assist the bead opposite the tool into the drop cen-
ter. Use one of the tire tools to pry the top bead into
the drop center.
6. Rotate the wheel counterclockwise while main-
taining pressure on the bead lifting tool until the first
bead is off.
7. Repeat the steps above for the rear bead.
8. Retract the tool and remove the tire.
Mounting
1. LUBE BOTH BEADS LIBERALLY.
2. Roll the tire onto the carriage and lean it back
against the rim.
3. Position the combo tool near the edge of the rim
as shown. DO NOT CONTACT THE RIM.
4. Securely clamp the vise grip to the rim edge at a
position to the left of the combo tool. Rotate the chuck
clockwise until the vise grip hooks the inner bead and
lifts the tire.
5. Continue rotating the chuck until the first bead is
mounted. Avoid rotating the vise grip into the
combo tool.
6. Remove the vise grip and repeat the steps above
to mount the outer bead.
When mounting a tire, the bead must be
started in the drop center of the rim. Failure
to use the drop center could result in dam-
age to the tire bead.
Note: It may be necessary to push the bead(s) into
the drop center during the mounting process.
Note: Tire lubricant greatly reduces the force needed
to demount or mount a tire. Liberally lube each bead
and rim edge while the bead loosener disc holds the
bead away from the rim. FAILURE TO APPLY LUBE
COULD RESULT IN DAMAGE TO THE TIRE BEADS.
