and then put the wheel over the threaded shaft and
adaptor.
Lube the bead area with water, pressing down on the
tire area i n several places to allow the
water to run into and around the bead. Also lube area
where the breaker arm will contact the sidewall
of the
tire.
Use only water as a lubricant removing
or
mounting
tires. Soap or some mounting lubricants may leave a
slippery residue which can cause the tire to shift on
the rim and lose air pressure during riding.
While holding t h e breaker a r m assembly a t an
approximate
45" position, insert the blade of the
breaker arm between the tire and r i m . Push the
breaker arm inward and downward until

Insert the threaded shaft through the appropriate
hole i n the breaker press head assembly. When
installing the press head block onto the breaker arm,
you may have to rotate the press head assembly to

press head assembly are in firm contact with the rim.
Tighten the press head bolt until the reference mark
on the press block is aligned with the top edge of the
press head.
Do not tighten past this reference mark.
If the rest of the bead cannot be pushed down into
the center of the rim by hand, loosen the press head
bolt and the lever nut.
Rotate the breaker arm assembly and breaker press
head assembly
t o the circumference of the
rim.
Tighten the lever nut and then tighten the press head
bolt as described.
