10 • Important: Always read and follow the operating instructions.
Bead Sealing
1.
Position valve stem in front of operator and con-
nect the infl ation 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 20 - Lift Tire Upwards for Bead Sealing
2.
Depress infl ation pedal to position 2 and hold
about one second to begin air fl ow through tire valve,
then depress pedal to position 3 and hold briefl y — less
than one full second. The blast of air from the jets will
expand tire and seal the beads.
3.
Release the infl ation pedal and allow it to return to
position 1. Verify that both beads are completely sealed
to the wheel. Repeat these steps if beads have not
sealed. It may be necessary to wait a few seconds for
the air storage tank pressure to recover before attempt-
ing again.
Note
If tire and wheel are properly lubricated and op-
erator cannot achieve bead seal after three or four at-
tempts, the valve core may be removed from the valve
stem to allow more air fl ow into the tire to assist with
bead seal. 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 infl ating tire.
An exploding tire, wheel, or bead sealing
equipment may propel upward and out-
ward with suffi cient 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. Defl ate 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
(infl ation pedal in position 1; foot removed from pedal),
continue to inject air into the tire (infl ation 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
(fi gure 21).
