TC39 Series Changer Operation Instructions
The left or the central pedal on the front of TC base is a two-stage design. Refer to
"Equipment Components," on page 9. The pedal controls the air going to the inflation
hose and the blast inflation nozzle.
CAUTION: Keep hands clear of wheel during sealing and seating of
bead.
CAUTION: When operating air inflation hose, do not lean over the tire.
Step down partially on the pedal to inflate tires through inflation hose.
Step down completely on the pedal to activate the blast inflator nozzle to seal tire
beads.
Refer to "2.6" on page 25 for complete inflation operation instructions.
As a safety device, the pressure limiter prevents the operator from using excessive
air pressure to seat the tire bead during tire inflation. Bead seating pressure should
never exceed 40 psi. If tires being mounted require more than 40 psi for inflation
pressure, the tire/wheel assembly should be removed from the tire changer, placed in
an inflation cage, and inflated per manufacturer's instructions.
While inflating the tire, the pressure gauge will read zero until the inflation pedal is
released. At that time, the gauge will give the correct air pressure reading in the tire.
Refer to "2.6" on page 25 for complete inflation operation instructions.
The bead press arm assists with tire mounting. The bead press arm moves in tandem
with the mount / demount head.
The controls on the bead press arm move the bead press up or down.
Refer to "Equipment Components," on page 9.
The command unit governs all the movements necessary for complete bead roller
operation. Refer to "Equipment Components," on page 9.
The command unit is used to position the bead roller and the tool into working
position.
Press the positioning push-buttons in order to press and pull the bead breaker rollers,
or the tool, on the correct rim diameter.
For proper operation of the command unit, place your hand over controller with index
finger and middle finger over lever buttons.
The command unit consists of 2 levers (pos. A) and of 2 push buttons (pos. B).
The left lever and push button control the lower bead breaker roller. The right lever
and push button control the upper bead breaker roller.
Each lever has 4 positions:
- Position 1 (rest position) stops the operated bead breaker roller in its current
position;
- Position 2 (held position) lowers the upper bead breaker roller or lifts the lower
bead breaker roller;
