COATS 4070 Tire Changer - Manual (Page 14)

10 • Important: Always read and follow operating instructions.
3. Inject frequent, short bursts of air into the tire by
pressing the Air-Flate pedal to position 2 and releasing.
Continue the bursts until the beads move outward into
their bead seat position.
Check the pressure frequently. If beads do not seat,
a problem exists. Investigate carefully and correct the
problem.

4. Proceed to the inflation step only when both beads
are completely and properly seated.
Inflation
DANGER
NEVER exceed tire manufacturer‘s recom-
mended air pressure. Tires can explode,
especially if inflated beyond these limits.
Keep hands, arms, and entire body back
from inflating tire. Avoid distraction during
inflation and observe tire pressure frequently
to avoid over inflation. Excessive pressure
can cause tires to explode, causing serious
injury or death to operator or bystander.
REMEMBER: If you removed the valve core for bead
sealing, it must be reinstalled before the tire is inflated.
1. Depress the Air-Flate pedal to position 2 and inflate
the tire. Release the pedal to position 1 and check the
increasing pressure frequently to avoid over inflation.
IMPORTANT: The 4070 is equipped with a pressure
limiter to assist the operator with proper tire inflation.
The 4070 limiter will keep most car and light truck tires
from inflating beyond 60 PSI (smaller tires may reach
higher pressures). Tires that require inflation above 60
PSI should be removed from the 4070 and inflated
using a safety chamber or safety cage. Tires can be over
inflated and explode even with the use of this pressure
limiter if other instructions in this manual and on the
unit are not followed. Check the function of the pres-
sure limiter regularly and maintain as required for safe
and proper operation.
IMPORTANT INFLATION FEATURE: If the Air-Flate
pedal is held steady at position 2, the Air-Flate system’s
pressure limiter will automatically cycle between infla-
tion and off. This cycle will continue until the pedal is
released. The operator should check the increasing
pressure frequently to avoid over inflation.
