OPERATION
Keep your hands and body as far away as
possible from the moving parts when
operating the machine, to avoid getting
hurt.
It is dangerous to wear necklace, brace-
lets and loose clothes.
Note: To avoid explossion in inflating, it is
important to check the tire and rim.
Before mounting the tire, pay attention to
the following points:
• Don’t mount the tire if the outside of tire
is damaged.
• Whether the rim is dented or deformed.
In particular, there will be small cracks
in the rims of alloy wheels, which cannot
be seen with naked eyes, which will
damage the durability of wheel, so there
will also be risks in inflating process.
• Make sure that the wheel rim and tire
are of the same size. If you cann’t make
sure of it, don’t mount the tire.
Make sure that the rim is firmly fixed to
the clamps.
Don’t put your hands on the wheel: if you
put your hands between rim and mounting
head, it may getting hurt when column
return to its original position.
Pic.7
Don’t put your hands on the wheel: if you
put your hands between rim and mounting
head, it may getting hurt when column

• Lubricate the tire beads with special grease in order to
avoid damaging them and to facilitate the mounting
operations.
• Clamp the rim firmly on the turntable.
• Move the tire so that the bead passes below the front
section of the mounting head is brought up against the
edge of the rear section of the mounting head itself.
• Keep the tire bead pursed down into the wheel rim
channel with your hands. Step pedal M to rotate the
turntable clockwise. Continue until you have covered
the entire circumference of the wheel rim.
• Insert the inner tube, if there is one. Repeat the above
operation for the other side of bead.
