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.

Operating Instructions

This unit must be properly operated and properly
maintained to help avoid accidents that could damage
the unit and injure the operator or bystanders. This sec­tion of the Operating Instructions manual reviews
basic operations and use of controls. These instruc­tions should be reviewed with all employees before
they are allowed to work with the machine. Keep these
instructions near the machine for easy reference.

Bead Loosening and Demounting

This machine may operate differently 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 combination duckhead®contacting the rim
causing scratches. On alloy wheels, always rotate the
wheel one turn after setting the duckhead to insure
proper wheel chucking.

Note: Always review with the owner any nicks and
scratches on expensive wheel and tire combinations
prior to servicing.

1. Deflate the tire completely by removing the valve

core from the valve stem (figure 1). Be cautious and do
not smoke as a

flammable gas could have been intro-

duced into the tire at some time

.

Figure 1 - Remove Valve Core to Deflate Tire

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.

ATV Note: It may be necessary on ATV wheels to

leave 3-6 PSI in some of these wheels to facilitate
bead loosening. Even after loosening one bead; it may
be necessary to reinflate to 5 PSI to loosen the oppo­site bead.

Note: Always loosen the bead on the narrow side of

the wheel’s drop center first (motorcycle wheels may
not have a narrow or long side, and some ATV wheels
may not bolt together). See figure 4 for more informa­tion on the drop center.

Remember: 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.

Note: 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. If using the optional bead loosener, lift bead

loosener shoe away from the machine. Adjust the
blocks so that the rim rests on top of them. Lay wheel
into position. Position the bead loosener shoe against
the tire next to, but not on, the rim. Depress the bead
loosener arm to loosen the bead. It may be necessary
to loosen the bead in multiple locations around the tire
(figure 2).

Figure 2 - Position Tire on Bead Loosener Shoe

CAUTION

CAUTION

3. Turn the wheel around and repeat loosening pro-

cedure on the other side of the wheel. This should be
the long side of the drop center.

Tip: It will be easier to clamp the wheel to the table

top if the lower bead is loosened last.

4. Apply tire manufacturer’s approved rubber lubri-

cant liberally to entire circumference of both tire beads
after loosening (figure 3).

Figure 3 - Apply Rubber Lubricant to Tire Beads.

5.

5. Next, observe the rim size from the tire, i.e. 15,

16, 17, etc. Turn the clamping screw to move the
clamps in the proper position (slightly wider than the
rim bead). It may be necessary to relocate the clamps
on the clamp carriers. Be sure each clamp is in the
same position before prelocating the clamps.

6. Determine the mounting side of the wheel. The

mounting side is the narrow side of the drop center
(tire removed in figure 4 for clarity).

Figure 4 - Determining Mounting Side of Wheel (note that
many motorcycle rims are symmetrical).

7. Using the tabletop locking knob (see letter G,

pages iv and v), lock the tabletop in place. This will
make mounting the tire/wheel assembly easier and
more positive. The tabletop has locking holes 90­degrees apart that the knob engages; it is not friction
lock. Place tire/wheel assembly on table top with
mounting side up (figure 5). Rotate the clamping screw
clockwise to move the clamps inward or crank coun­terclockwise to move the clamps outward. Clamp
motorcycle and ATV wheels from the outside (clamps
push inward against the outside rim edge). Place rim
flange into rear clamp and slowly move the other

clamps inward until they contact the rim. Observe
closely to prevent tire/wheel damage. If clamps are
properly positioned and the tire/wheel assembly is
secure, loosen the tabletop locking knob and proceed.

Figure 5 - Place Tire/Wheel Assembly on Table Top

Figure 6 - Rotate Clamping Screw to Move Clamps Into Position

8. 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 demount head into
contact with the rim edge. Push the locking handle

back to lock the slide into
place. As the slide is locked,
the mount/demount head
will move upward approxi­mately 1/8-inch from the
rim edge.

Note: On plastic duck-

heads, the upward move­ment should be limited to
1/16-inch maximum.

Figure 7 - Position Mount/Demount Tool

9. The Duckhead®roller should be in contact with the

rim edge. Turn the swing arm adjusting knob to move
the head away from the rim 1/8 to 1/4-inch. On expen­sive and polished rims, it is recommended a plastic
bootie (p/n 8183373) be used over the duckhead roller.

Important: Always read and follow the operating instructions. • 3

10. Check duckhead®positioning. Mount/demount

head should be positioned with 1/8 to 3/16-inch clear­ance between the top of the rim edge and the bottom
of the head (with plastic duckhead it is recommended
the vertical clearance be limited to a maximum of 1/16­inch) and 1/8 to 1/4-inch clearance between rim edge
and the head. This clearance will be maintained as long
as locking handle and adjustment knob are not
changed. The operator may swing the arm out of the
way and back into place again without needing to repo­sition the head (when clamping a like set of wheels).

Figure 9 - Proper Mount/Demount Head Position

Important: The vertical tool clearance may change
with machine use and should be inspected often.
Failure to maintain the proper clearance may result in
finish/painted/plated damage to the wheel rim.

11. Insert the smooth curved end of the bead lifting

tool over the forward end of the demount head and
below the top bead of the tire. Use your free hand to
press down on the tire opposite the head to help with
tool insertion.

Figure 10 - Insert Bead Lifting Tool

12. Rotate the bead lifting tool down towards the

wheel to lift the tire bead up and over the knob portion
of the demount head. The lift tool may be removed if
desired (figure 11).

Figure 11 - Lift Bead Over Demount Head

13. Rotate the wheel clockwise. If additional lever-

age is needed, insert the table top rotating handle into
the receiver and use the handle to rotate the table top.
The demount head will guide the upper bead up and
over the edge of the wheel.

Figure 12 - Use Table Top Rotating Handle For Leverage

Note: Push down on the tire across from the

demount head during table top rotation to utilize the
drop center area of the wheel. This reduces the ten­sional force on the bead during demount.

14. Lift and hold the tire at an angle so that the

lower bead is resting in the drop center directly across
from the demount head, and is loose below the
demount head. Insert the smooth curved end of the
bead lifting tool down over the forward end of the
mount/demount tool and below the lower bead. Lift
the bead up and over the knob on the demount head
(figure 13).

Figure 13 - Demounting Lower Bead

15. Turn the table top to rotate the wheel. The

demount head will guide the bead up and over the
edge of the wheel. Continue rotation until lower bead
is demounted.

Note: With tube-type tires, demount the upper bead

and remove the tube before demounting the lower
bead.

Note: Normal table top rotation for demounting is

clockwise.

At times during the mounting and
demounting procedure, the bead lifting tool
may encounter resistance or come under
load. Keep one hand firmly on the tool to
avoid possible tool disconnect. Turn the
table top counterclockwise to back out of
jam ups.

After successfully completing the demount

process, proceed to MOUNTING.

Operator Protective Equipment

Always wear durable work clothing during tire serv­ice activity. Shop aprons or shop coats may also be
worn, however, loose fitting clothing should be
avoided. Tight fitting leather gloves are recom­mended to protect the 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.

6 • Important: Always read and follow the operating instructions.

Mounting

This information must be read and followed carefully

to prevent accidents and injuries during mounting.

Check tire and wheel carefully before
mounting. Make sure the tire bead diameter
and wheel diameter match exactly. Consult
the Rubber Manufacturer's Association for
approved rim widths for tire sizes. Mis­matched tires and wheels explode.

Never mount a tire and wheel handed to
you by anyone without checking both tire
and wheel for damage and compatibility.
The problem of mis-matched tires/wheels is
preventable. Be extra cautious of persons
without knowledge of tire service. Keep
bystanders out of service area; there is a
risk that could result in injury.

Never mount a damaged tire. Never mount
a tire on a rusty or damaged wheel.
Damaged tires and/or wheels may explode.

If you damage the tire bead during mount­ing, STOP!, remove the tire and mark it as
damaged. Do not mount a damaged tire.

1. Inspect the wheel closely for damage. Clean the

wheel and remove any light corrosion or rubber residue
(figure 14). Do not attempt to service heavily corroded
wheels.

Figure 14 - Inspect and Clean the Wheel

2. Inspect tire for damage, paying close attention to

the beads. Verify size match between tire and wheel.

3. Lubricate tire beads liberally with tire manufac-

turer approved lubricant (figure 15).

Figure 15 - Lubricate Beads

4. Place tire over wheel and move swing arm into

position. Position the tire so that the lower bead is
above the rear extension of the mount/demount head
and below the front knob (figure 16).

Figure 16 - Position Tire Against Mount/Demount Head

5. Turn the table top and rotate the wheel to mount

the lower bead. Use the drop center of the wheel to
reduce the tensional force on the bead by pressing
down on the tire directly across from the mount head.
Rotate table top until lower bead is fully mounted.

6. For top bead, rotate table top until the valve stem

is 90 degrees forward of the mount head. Lift the
upper bead up and over the rear of the mount head.
With your left hand press down on the tire between
the mount head and the valve stem to hold the tire in
the drop center. Rotate the tire until the bead is
mounted. Continue to press down on the tire during
the remaining mounting process.

Do not force the tire onto the rim. Bead
damage could result making the tire unsafe
and/or creating the risk of injury.

Note: If table top rotation begins to jam, reverse the

table top momentarily until the tire bead is again loose
on the wheel. Reposition the mount head, make sure
the bead is correctly positioned in the drop center of
the wheel; then attempt mounting again.

Note: For low profile or stiff sidewall tires, it may be

advantageous to use the bead lifting tool to initially
hold the upper bead down in the drop center

Note: For tube type tires, mount the lower bead first,

move swing arm out, install the tube, and then mount
the upper bead.

When you have completed the mounting process,

proceed to inflation.

Inflation

Do not inflate tire while wheel is clamped to
the Table Top. 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, damage, or
defects before mounting. Always use
approved tire bead lubricant during mount­ing and inflation.

Do not inflate tire while wheel is clamped to the table
top. Remove tire and wheel assembly from machine to
inflate. Use a remote controlled inflation device when
inflating; to seat beads, use a small amount of air inter­mittently; never exceed the tire manufacturer’s recom­mendation when inflating. If beads do not seat,
remove air and relubricate beads. After tire is properly
inflated secure bead locks were required.

ATV Tire Inflation: ATV tire inflation is unique in that
the bead seat pressure allowed is more than the oper­ating pressure. ALWAYS follow the tire manufacturer’s
information on inflation. This information can be printed
on the sidewall, on the tire sticker, or from the manu­facturer.

present.

Floor Mounting

The machine should be securely bolted to the floor
with suitable anchors using the hole at each corner of
the machine base.

Assembly Instructions

Please inspect this unit for damage/missing parts
prior to use.

Carton Contents (boxes marked 1 through 3):

Contains the base, tower and table top for your RC­50M Manual tire changer. Be sure to check all contents
prior to assembly.

(Optional) Carton Contents (box marked 4):

Contains the Bead Loosener. Be sure to check all con­tents prior to assembly.

Base Assembly: Enclosed with base unit you will
find 4 (four) anchor bolts (1/2” X 3”) choose the loca­tion for the base at this time being sure to position the
RC-50M in a clear working area. (It is suggested that
the unit is firmly mounted to the floor prior to attaching
the tower or table top.) Attach the tool tray to the base
with supplied hardware.

Tower Assembly: Using the supplied hardware 4
(four) (12mm X 55mm hex bolts) that attaches the
tower to the base of the RC-50M, position the tower in
place. Attach the swing arm to the tower, (at this time
it is suggested that grease be added to the pivot shaft.)
The slider may be put into place at this time, (add the
return spring prior to placing the slider in the swing­arm guide) once placed attach the bead head. Check
travel, clearances and locking mechanism prior to use.

Table Top Installation: Prior to installation BE SURE
TO PLACE THE TABLE TOP WITH THE LOCKING KNOB
FACING FORWARD FOR ACCESS WHEN RC-50M IS
IN USE. Once the table top has been positioned check
all clearances for complete 360-degree rotation. Place
wheel jaws at desired position, making sure to place

holding pin completely through the guild hole prior to
locking the wheel in place.

Bead-head Adjustment: Prior to using your RC-50M

you should take a few moments to check the align­ment of the bead-head. This is a simple procedure that
will require a 4.5mm hex wrench and an 18-inch wheel.
Set the jaws in place to accept the 18-inch wheel
(using a bare wheel will ease the adjustment process),
tighten the jaws so that the wheel is held in place.
Lower the bead head until contact is made between
the plastic rim protector and top outer edge of the
wheel. If they do not match-up, make the following
adjustment using the two adjusting screws (located
side-by-side on the bead-head mounting base, fig.1) If
needed, rotate the head until contact is made with the
wheel. The plastic protector should be touching the
wheel as close to the center as possible. The rear por­tion of the bead head should overlap the outer edge of
the wheel so that there is approximately 1-3mm over­hang (fig. 2.) Offset changes are made with the two
adjusting screws.

Assembly for (Optional) Bead Loosener: Check all

contains prior to assembly. Attach support to the base
using the supplied hardware. At this point you may
now attach the link, breaker and lever arm to the sup­port. The Bead Loosener will attach to the RC-50M by
hooking on to the locating mount.

TIRE FAILURE UNDER PRESSURE IS HAZ­ARDOUS! This tire changer Will Not Restrain
Exploding Tires, rims or other related equipment.

TIRES CAN EXPLODE, ESPECIALLY IF INFLATED
BEYOND SPECIFIED LIMITS. DO NOT EXCEED
TIRE MANUFACTURERS RECOMMENDED AIR
PRESSURE.

AN EXPLODING TIRE, RIM, OR BEAD SEATING
EQUIPMENT MAY PROPEL UPWARD AND OUT­WARD WITH SUFFICIENT ENERGY TO CAUSE
SERIOUS INJURY

OR DEATH TO OPERATOR

AND/OR BYSTANDERS.

DANGER

READ…

Mounting and inflating the
wrong size tire can get
you hurt.

Read

the size on
the tire and make sure it
matches the rim. Be espe­cially careful about putting
a smaller tire on a larger
rim, such as a 16-inch tire
on a 16.5-inch rim.

Inflation of a mismatched
tire and rim can cause an
explosion.

INSPECT…

Before you put any tire on
a rim,

inspect

the rim for
rust, tough spots, bent
edges, or cracks that could
prevent the tire from seat­ing right. If you spot any of
these problems, don’t
mount the tire until the rim
has been checked by your
shop foreman.

Inspect

the tire for bead

damage.

MOUNT…

Once you’ve made sure the tire is OK
and the right size and the rim is OK,

mount

the tire safely. NEVER, ever
lean over the tire when you’re inflating
it. If a tire does explode, it will go
straight up. You don’t want to be over
the tire if that happens. Also, never
over-inflate the tire, even if the bead
doesn’t seat. Never inflate over 40 PSI.
If the tire hasn’t seated, something is
wrong. Deflate the tire and check it
and the rim again. If it doesn’t work the
second time, try another tire.
