Operator Protective
Equipment
Personal protective equipment helps make tire servicing 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 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.
Consideration 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.

mounting and seating the beads.
NEVER
use
antifreeze, silicone, or petroleum base lubricants.
ALWAYS
clean and inspect the wheel.
NEVER
mount a tire on a damaged or rusty wheel.
Wheel damage or rust may cause tire or wheel failure
during inflation. Explosion from failure may result in
severe injury or death of the operator and bystanders.
ALWAYS be sure the bead opposite the tool is in the
drop center before rotating the tire when demounting
or mounting to avoid damage to the tire beads.
Inflation
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. 5000 is not designed as a safety
device or stand for bead seating or inflation.
ALWAYS
use an approved inflation chamber or infla-
tion cage.
The following safety instructions are for one piece
wheels only. Refer to the manufacturer’s or R.M.A.
procedures for multipiece wheels.
ALWAYS
use an approved inflation chamber or inflation cage equipped with a grip chuck and a remote
inflation gauge and valve. DO NOT OVER INFLATE!
Tire or wheel failure during and after inflation may
result in an explosion capable of causing severe injury
or death.
ALWAYS
inflate the tire to manufacturer’s recom-
mended cold operating pressure.
NEVER
reinflate a tire that has been run underinflated or flat without first demounting the tire and
checking for wheel and tire damage.
ALWAYS
inspect the tire interior for loose or broken
cords, cuts, penetrating objects, and other damage to
the carcass. Discard tires that cannot be properly
repaired.
NEVER
rework, weld, heat or braze wheels.
NEVER
strike the tire or wheel with a hammer.
ALWAYS
be sure the tire diameter exactly matches
the wheel diameter.
Tire failure under pressure can be hazardous. Place the wheel inside an approved
inflation chamber or cage before inflating.
Use an approved remote inflation valve,
hose, and gauge. ALWAYS wear safety goggles 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
pressure frequently. Do not exceed the
manufacturer’s recommended maximum
inflation pressure. Failure to follow these
instructions may cause the tire and rim to
separate with tremendous force, resulting
in serious personal injury or death.

H.I.T. 5000
Installation
It is not necessary to bolt the H.I.T. 5000 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. 5000 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.
Electrical Installation
The H.I.T. 5000 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. 5000 to the power source. The licensed electrician must sign the warranty registration card to validate the warranty.

H.I.T. 5000
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 methods 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 loosening 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 demounting and mounting process. While the bead loosening
tool is pushing the bead away from the rim edge, liberally 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 center.
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 center. 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 damage 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 sidewall. This will regain some of the original flexibility of
the rubber, thus reducing possible damage to the sidewall.
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 damaged.
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.
There are two methods of spreading the tire with the
roller tool.
Method A:
1. With the first bead removed, hook the roller tool
over the outer bead and move the tool away from the
rim to spread the beads and gain access to the inside
of the tire.
Method B:
1. With the tire completely demounted and the rim
removed from the clamps, hook the inner bead over
the clamps and the roller tool over the outer bead.
Move the tool away from the inner bead to gain access
to the inside of the tire.
Tire Spreading
Note:
The wheel can be rotated with the roller tool still in place,
but the tool should be moved toward the wheel slightly. This will
relieve some of the pressure on the bead, thus avoiding any
damage, which might occur from over stretching the bead.
Tire failure under pressure can be hazardous. Place
the wheel inside an approved inflation chamber or
cage before inflating. Use an approved remote inflation valve, hose, and gauge. ALWAYS wear safety
goggles 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 pressure frequently. Do not exceed
the manufacturer's recommended maximum inflation pressure. Failure to follow these instructions
may cause the tire and rim to separate with tremendous force, resulting in serious injury or death.
