10.4. Functional Parts
Fig 12 shows functional parts to the 036 device:
A. Rotating arm connector B. Hexagonal horizontal arm
C. Tire lifting roller s
upport D. Tire lifting roller
E. Raise-fall control assembly
G. Tire pressing roller
10.5. Trial operation
The 036 device must connect with the air compressor, and the air pressure from 8 bars to
10 bars is desirable.
10.6. Operations
Mounting and demounting big flat tire is difficult work. By the help of 036 help arm to

pedal to open the jaws；
Put the tire on the turntable; Tread the corresponding pedal to close the jaws until they near the rim.
10.6.2. Demounting The Tire
-1. Generally speaking, tire is very tight. Loosen the beads with the tire pressing head first (or using
the bead breaker if it too tight to loosen).
Pull out the Hexegonal horizontal arm; let the tire pressing roller above the tire without collision.
Lower the tire pressing roller lower with the switch handle to press the tire. Tread the pedal to rotate
the turntable. Loosen the bead during this procedure. (Fig 13)
Caution：Lubricate the tire pressing head (upper) and the bead before the operation.
-2. Demounting the upper bead
a- Move the mounting head near the edge of the rim, rotate the tire pressing arm to move the tire
pressing block above the tire, press the switch handle to depress the tire, and insert the lifting lever
in the clearance between the tire and the rim, then hang the bead on the mounting head. (Fig 14)
b- Raise the auxiliary arm, rotate the tire pressing head to the opposite. Press the tire with the switch
handle to create enough space.
c- Tread the power supply pedal to rotate the turntable. With the help of the tire pressing head, the
upper tire bead is detached. If you thread the power supply pedal again, you can quickly demount
the tire upper lip.
d- Raise the help arm to move the tire pressing block to its non-working position.
-3. Demounting the bottom bead
Turn the roller support and move it under the tire, but don’t touch it with the rim.；(Fig 15) Tread
the power supply pedal to rotate the turntable, meanwhile, lift help arm gradually to loosen tire and
completely demount the bottom bead. If you thread the power supply pedal again, you can quickly
demount the tire.
Caution: The roller support can’t be used for all tires, some tires need following operation: Move
the mounting head above the rim; Insert the lifting lever in t
he clearance between the bottom tire bead
and the rim, have the tire hung on the mounting head(Fig 12)；Tread the power supply pedal to rotate
