This pulls the top Bead over the Demount Lip, which is what you want.
⚠
CAUTION
Hold on to the Bead Lifting Tool
. Depending on the Tire, it may take a
good deal of force to move the Bead up and over the Demount Lip. If you were
to release the Bead Lifting Tool at this point, it could easily injure the Operator
or damage the Wheel, Tire, or the Tire Changer.
Check to make sure the Bead Lifting Tool is lifting the Tire Bead up and over the Demount Lip of
the Mount/Demount Head. If the Tire Bead is
not
coming up and over the Demount Lip, pull the
Bead Lifting Tool out and start again.
On some Tires, it may take multiple attempts
.
8.
When the Bead Lifting Tool has moved all the way over to the middle of the Wheel, check the top
Bead to make sure it is above the Demount Lip.
The top Bead
must
be above the top of the Demount Lip to proceed.
Continue holding the Bead Lifting Tool
.
9.
Press down and hold down the Turntable Foot Pedal; the Turntable begins turning clockwise.
Note
: If you have difficulty getting the Turntable to move clockwise, release the Turntable Foot
Pedal, keep hold of the Bead Lifting Tool, and then press up on the Turntable Foot Pedal
for few seconds to move the Turntable counterclockwise, then press down again to
move clockwise. Repeat as necessary to clear up the difficulty.
Watch the top Bead to make sure it is being pushed over the Rim, all the way around the Tire, as
the Turntable moves.
10.
Keep turning the Turntable until the entire top Bead pops over the top of the Rim.
11.
When the top Tire Bead pops over the Rim, release the Turntable Foot Pedal and remove the Bead
Lifting Tool.
The top Bead is demounted.
The next step is to demount the bottom Bead over the top Rim.
12.
Make sure there is still lubricant on the bottom Bead and the top Rim.
If there is not, put some more on.
13.
Push the bottom Bead up as much as possible all the way around the Wheel, then push the side of
the Tire opposite the Mount/Demount Head into the Drop Center of the Wheel.
If you are using the R76ATR, you can position the Helper Disc to help hold up the Tire. If you are
using the R76LT, you can manually lift the Tire.
