2.2 OPERATION
It is difficult to demount and mount big low profile tire. If operation is proper,

bead, rotate turntable, lift roller C (G, Figure 16).
2. Move demount/mount head close to edge of rim, keep a 2-3mm gap between demount/mount
head and rim plane, lock vertical arm, adjust screw bolt in column to position swing arm.
3. Nearby demount/mount head, insert lift lever N into tire, use lift lever to lift bead upon knob
of demount / mount head. Manually rotate roller C to inner side pull handle D down, make
roller C to press rim keep 3-5mm gap between demount/mount head and rim, make sure
demount/mount head not damage rim, rotate tire installation base, demount tire upper bead
(Figure 18)
