Important: Always read and follow operating instructions.
Bead Sealing
1.
Remove the valve core from the valve stem to
allow more air flow into the tire to assist with bead
seal.
2.
Position valve stem in front of operator and con-
nect the inflation hose with the clip-on chuck. Hold
tire up against upper edge of the wheel. Be sure tire’s
top bead does not cover the bottom of the valve stem
(figure 27).
Figure 27 - Lift Tire Upwards for Bead Sealing
3.
Depress inflation pedal to position 2 and hold to
begin air flow through tire valve.
4.
If tire beads do not seal, then use the Auxiliary
Bead Sealer (ABS), see figure 28. Verify that both
beads are completely sealed to the wheel. Repeat
these steps if beads have not sealed. It may be neces-
sary to wait a few seconds for the air storage tank
pressure to recover before attempting again.
Figure 28 - If Necessary, Use ABS for Bead Sealing
5.
After bead seal is achieved, remove the clip-on
chuck and reinstall the valve core. Reattach the clip-on
chuck after core is installed.
Bead Seating
NEVER exceed 40 PSI to seat beads while
using this tire changer. If more than 40 PSI
is permitted by tire manufacturer, ALWAYS
use safety cage and clip-on chuck. NEVER
exceed recommended pressure after seat-
ing beads. ALWAYS keep hands and entire
body back from inflating tire.
An exploding tire, wheel, or bead sealing
equipment may propel upward and out-
ward with sufficient force to cause serious
injury or death to operator or bystander.
Check tire pressure frequently. If operator
is unable to obtain Bead Seat, something
is wrong. Deflate tire completely, inspect
tire and wheel, correct any problems found,
relubricate both tire beads, and reattempt
Bead Seal and Seat procedures. Follow all
safety instructions in this manual and on
machine.
1.
Once tire pressure is indicated on the air gauge
(inflation pedal in position 1; foot removed from pedal),
continue to inject air into the tire (inflation pedal posi-
tion 2) in short intervals. Check the pressure frequently.
Stand back during bead seat. Keep hands, arms, and
entire body away
from tire during this
procedure (figure
29).
Tire beads should
move outward and
“pop” into their
bead seat position
as pressure inside
the tire increases.
If this does not
happen, a problem
exists. Investigate
carefully.
Important:
Do
not continue to add
air pressure to force
bead seat.
