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.

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.

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.

Bead Loosening and Demounting
1. After chucking the wheel, position the bead
loosener disc against the sidewall within 1/4 inch of the
lock ring. Do not contact the ring.
2. Rotate the wheel and slowly advance the bead
loosener disc until the bead is loosened. LIBERALLY
LUBE THE TIRE BEAD AND RIM.
3. Use the ring tool to remove the lock ring(s).
4. Raise the tire and move the bead loosening disc
into position on the inner bead. Do not contact the rim.
5. Rotate the wheel and slowly advance the disc to
push the tire about half way off the wheel. Push the
valve stem inside the wheel, then finish pushing the
tire off the wheel.
The tube will be damaged if the operator
fails to push the valve stem into the wheel
before completely removing the tire.
Mounting
1. Roll the tire onto the carriage, and align the rim to
the center of the tire.
2. Liberally lube both beads and the rim. Slowly
advance the carriage and guide the tire onto the rim.
Stop about 1/3 of the way on and insert the tube.
3. Place the bead loosening disc in the carriage.
Position it against the tire bead and push the tire onto
the rim.
4. With the disc pushing on the outer sidewall, install
the ring(s).
CAUTION
Wheels with Lock Rings

Bead Loosening
1. Remove the valve core. Deflate the tire away from
the machine and remove any calcium chloride or other
substances from the tire prior to rolling the wheel onto
the tire changer.
2. After locking the wheel on the chuck, move the
bead loosening disc into position near the edge of the
rim.
Note: Apply a liberal amount of lube to the tire side-
wall. This will regain some of the original flexibility of
the rubber, thus reducing possible damage to the side-
wall.
3. Rotate the wheel and slowly move the bead loos-
ening disc into the sidewall until the bead is loosened.
4. Continue to rotate the tire and apply a liberal
amount of lube to the bead and the rim.
5. Move the bead loosening tool to the inner bead
and repeat the above steps.
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.
Demounting
1. Advance the combo tool close to the rim, with the
finger past the rim edge.
2. With the spade tool inserted between the rim and
the outer bead, on the right of the combo tool, pry the
bead out over the rim edge.

3. Rotate the wheel counterclockwise while main-
taining pressure on the spade tool until the outer bead
is demounted. Push the valve stem inside the rim and
pull the inner tube out of the tire.
Note: It is possible to roll one or both beads(s) off the
rim with the bead loosener disc instead of the combo
tool. However, care must be taken not to damage the
tube or the valve stem. By alternately rotating the
wheel first counterclockwise, then clockwise, being
careful not to pass over the valve stem, the tire may be
demounted using this method. If the tire is wide, the
rim is thin or weak, or the side wall is tough, do not use
this method since the bead or the rim may be dam-
aged.
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.
Mounting
1. Lube both beads and the rim liberally.
2. Rotate the rim so the valve stem hole is directly
on the bottom, then roll the wheel onto the carriage.
3. Move the combo tool into position near the edge
of the rim.
Note: Mounting of the outer bead is shown in order
to see the position of the tools. Position of the tools
will be the same for the inner bead.
4. Lean the tire against the rim and clamp the vise
grip on the edge of the rim to the left of the combo
tool. Rotate the chuck to lift off the carriage.
5. Using one of the tire tools to assist the bead into
drop center, continue rotating the chuck until the inner
bead is mounted.
6. Insert the inner tube and repeat the above steps
to mount the outer bead.
Note: Avoid damage to the valve stem by never
allowing the stem to pass the stationary tool.

Demounting
1. By operating the carriage to the extended posi-
tion, the table will be rotated to the horizontal position.
2. Place the tire and rim over the table top by rolling
into place and then leaning back onto the table.
3. Again, using carriage handle, rotate table back to
vertical position. As this occurs, the tire and rim will fol-
low and end up sitting on top of the table.
Ensure that table cylinder is retracted when
the above operation is done so there will be
no damage to the cylinder shaft.
4. When the table is in the vertical position, manually
center the tire and rim so that it lies perpendicular to
the table cylinder.
5. Place the tire compressor on top of the tire and
pin it to the clevis affixed to the table cylinder.
Adjust the four arms of the compressor to
just clear the lock ring.Tighten all of the "T"
handles so they won't move.
Ensure at this point that the tire has been
completely deflated and the valve core
removed from the valve stem.
6. Compress the retaining ring and tire down enough
to clear the lock ring. Using the ring tool, remove the
lock ring.
7. Extend the table cylinder and remove the com-
pressor, lock ring, retaining ring and rim seal.
8. Rotate table to the horizontal position. Remove
tire and rim, then replace them after turning them 180
degrees.
9. Rotate table back to vertical position.
Note: Rim face should now be on bottom.
10. Reinstall compressor and pin it to the clevis
affixed to the table cylinder.

12. Remove compressor and rim from table top.
13. Rotate table to horizontal position and remove
inner and outer tire from table.
14. Roll tire onto carriage platform and clamp bead
into deepest "V" in jaws.
The hydraulic pressure regulator knob,
located on the swinging pod front, should
be set at minimum pressure. Also, care
should be taken to ensure that the beads
are not overly stretched.
15. Using the longest of the two nylon web straps,
place the strap around the top of the inner tire and the
cross brace of the table linkage. The carriage should be
in the retracted position. Using socket and ratchet,
tighten strap as shown.
Note: The vertical cylinder should be lowered to a
point where the tire just clears the carriage.
16. Move the carriage to the extended position,
thus pulling the inner tire out of the outer tire. If the
two tires are not separated when the carriage has
reached its extended position, further travel can be
reached by raising the vertical cylinder until the two
tires are separated.
17. Remove the web strap from the inner tire, and
remove the outer tire from the clamps of the machine.
CAUTION

Mounting
1. Place the two inner tire side plates into the car-
riage forward holes facing each other as shown above.
2. Place the shortest nylon web strap down on the
center of the two side plates.
Note: Ensure that the ratchet end of the strap is to the
outboard of the side plates and the flat side is facing up.
3. Roll the inner tire over the strap and between the
two side plates. Ensure that the two slits in the inner
tire are placed opposite one another and parallel to the
ground.
4. Compress the inner tire by pushing down on it
with the clamps.
Note: The jaws should be spread to a point that the
arms are parallel to the ground. While compressing the
inner tire, ensure that the inner tire is maintained in a
vertical position.
5. After the inner tire is compressed to its lowest
point, place strap around inner tire and tighten with
socket and ratchet as shown above.
6. Raise the clamps and remove the strapped inner
tire from the side plates. Then remove the side plates
from the carriage.
7. Roll the outer tire onto the carriage and clamp the
bead into the deepest "V" in jaws.
The hydraulic pressure regulator knob,
located on the swinging pod front, should
again be set at minimum pressure. Also, care
should be taken to ensure that the beads are
not overly stretched.
8. Place the two bead spreaders into the lower edge
of the bead with the other end hooked into the open-
ings of the tire ramps (angles welded to the side rails).
Then, lift the tire up until the bead is spread open
slightly.
Note: Apply a liberal amount of lube to the front bead
of the outer tire and the edges of the spreaders in the
area of the bead.

ALWAYS follow all applicable Local, State, and Federal
Codes, Rules, and Regulations; such as the Federal
OSHA Standard Number 1910.177.
NEVER seat beads or inflate a tire on the tire changer.
The H.I.T. 5000H2 is not designed as a safety device or
stand for bead seating or inflation.
ALWAYS use an approved inflation chamber or infla-
tion cage.
Tire failure under pressure can be haz-
ardous. Place the wheel inside an approved
inflation chamber or cage before inflating.
Use an approved remote inflation valve,
hose, and gauge. ALWAYS wear safety gog-
gles for eye protection. Do not stand beside
the wheel or cage during inflation. Keep
hands and other parts of the body out of the
cage during inflation. Observe the tire pres-
sure frequently. Do not exceed the manufac-
turer's recommended maximum inflation
pressure. Failure to follow these instruc-
tions may cause the tire and rim to separate
with tremendous force, resulting in serious
personal injury or death.
