2 • COATS Bump-n-Roll

Installing your new “Bump-n-Roll”

1. Remove the Torx T40 screws from the lower
front bead loosener pad on your 5030, 5050,
5060, or 6060 tire changer and remove the
bead loosener pad.

NOTE: Clean off any dirt and/or debris that
may have accumulated around the bead
loosener pad so that the Bump-n-Roll
assembly has an even surface for mounting.

2. Place the Bump-n-Roll assembly on the floor
next to your COATS tire changer and line up
the holes in the Bump-n-Roll assembly with the
screw holes in the side of the tire changer
where the bead loosener pad was removed.
On 5030 machines, line up two (2) holes at
front of the Bump-n-Roll assembly and install
the extension plate under the upper flange of
the Bump-n-Roll assembly with the two (2) 1/4­20 screws supplied. (See Parts Listing)

3. Replace the bead loosener pad (over the
Bump-n-Roll bracket) with the four (4) new
screws supplied with the Bump-n-Roll
accessory. You are now ready to “Bump-n­Roll”. (Discard excess hardware)

Using your new “Bump-n-Roll”

Parts List — “Bump-n-Roll”

With the new Bump-n-Roll, encountering a stubborn
bead will be an easier process. When the bead is
loosened the first time (with the valve stem at the 2
o’clock position) and the user finds it is necessary to
loosen the bead at another location; hold the bead
loosener shoe away from the tire with one hand and
then roll the tire forward with adequate force into the
Bump-n-Roll apparatus and the tire will spin to an
alternate location for additional bead loosening.

In the past when a stubborn bead was encountered,
the user had to roll the tire back away from the bead

loosener , release the bead loosener handle, pick up
the tire and spin it the desired amount, grab the
bead loosener handle, open it to the desired width,
and roll the tire back into the bead loosening area.

When servicing tires on
wheels which have the old

style strap-on pressure
sensors; take care not to damage the sensor.
Sensor is located directly opposite the valve stem.
