PNEUMATIC BEAD ASSIST ARM
Up/Down Control Switch - Toggle switch allows single
fi nger operation of all pneumatic PBA functions, with or
without gloves.
Top Bead Roller - Provides easily controlled pneumatic
power to drive upper beads down into the wheel drop
center (while tire is turning) for easy lubrication prior to
dismounting. Also provides pneumatic power assistance
for safely remounting second bead on extremely low profi le
and Run Flat design tires.
Bead Depressor - Provides easily controlled pneumatic
power to depress the tires sidewall during the remount
cycle. This will prevent premature bead seating before the
entire bead has been reinstalled on the wheel. Provides
an added level of safety by keeping the technicians hands
away from the bead area during this potential pinch point
procedure. Additionally the Bead Depressor "follows" the
tire around while turning to guarantee successful remount
fi rst time everytime.
Bottom Bead Roller - Provides easily controlled
pneumatic power to unseat stubborn lower beads which
may have accidentally reseated after the original bead
breaking procedure. Also allows a technician to raise and
hold wider tires up, to assist in safely and easily getting the
second bead up onto the mount/demount head.
Wheel Centering Depressor - Provides downward
pressure on a rim when working to clamp a low profi le
tire/rim combination. Will assist the technician in correctly
seating the rim clamps between the tire and the rim when
clamping from outside in where it is diffi cult to depress the
tire sidewall enough to expose the rim edge.
