P/N 5900158 — Rev. E1 — Nov. 2019
Break the Beads
The Beads must be broken – on both sides of a Tire – before the Tire can be demounted.
⚠
WARNING
Do not Break the Bead of a Tire until
you
have made sure the Tire is fully deflated.
A Tire with air still in it could explode, injuring the Operator or bystanders.
The Bead is broken when the Tire Beads come out from between the Rim Lip and the Bead Retainer
(the Bead Seat) all the way around the Tire, on both sides of the Tire.
To break a Tire’s Beads
:
1.
Make sure you are wearing OSHA-approved (publication 3151) personal protective equipment:
leather gloves, steel-toed work boots, back belts, hearing protection, and ANSI-approved eye
protection (safety glasses, face shield, or goggles).
2.
Check the Tire again to make sure it is
fully
deflated.
3.
Check both sides of the Tire to make sure all Wheel weights (from balancing) have been removed.
If they have not, remove them.
⚠
CAUTION
Breaking the Beads of a Tire with Wheel weights could damage the Tire Changer
and/or the Wheel.
4.
Identify the Narrow side of the Tire whose Beads you are breaking; break this side first.
5.
Move the Tire into position between the Pads and the Bead Breaker Blade, with the Narrow side of
the Tire on the Blade side.
6.
Depending on the size of the Tire whose Bead you are breaking, you may need to adjust the
position of the Blade or use the Adjustment Rod to adjust the Bead Breaker Mechanism.
Refer to
7.
If you are Breaking the Beads of a Tire with a TPMS, put the sensor at 12 o’clock high or 6 o’clock
low (relative to the ground), to reduce the chances of damaging it.
8.
Move the Blade so that it is on the side of the Tire, very close to,
but not touching
, the Rim.
⚠
CAUTION
Make sure the Blade is
not
touching the Rim. The Bead Breaker Mechanism uses
a great deal of force; the Rim could be damaged if the Blade pushes on it instead of
the side of the Tire.
