Clamp the rim
• Step the pedal (Z) to the central position and locate the
clamp (G) according to the reference scale of the
turntable.
• Place the tire on the clamp so that the rim is near the
lowest part of the clamp and step on the pedal (Z) to
the bottom.
• Make the clamp (G) closed completely.
• Place the tire on the clamps and step the pedal Z to
clamp the rim.
• Lower the operating arm (M) until the dismounting head
is supported on the rim edge and locked with the
locking handle (K).In the process, the operating arm is
locked in a fixed position in the vertical direction, and
the working head is moved to 2mm above the rim.
Note：Once the operating arm is locked in the vertical
direction, the working head must be manually removed
from the rim (approximately 2mm) with the manual wheel
on the left side of the horizontal swing arm.
• With the crowbar T interested between the bead and
the front section of mounting head I, move the tire bead
over the mounting head I with crowbar T(see pic.10).
Note：In order to avoid damaging the inner tube, if there
is one, it should be 10cm to the right of the mounting
head I about the above operation.
• While the crowbar in this position, rotate the turntable
Y clockwise by pressing down on pedal V until the tire is
completely separated from the wheel rim.
• Remove the inner tube if there is one. Repeat the same
operation for the other bead.

14
www.mechmaxx.com
Don’t put your hands between tire and
clamps in operating clamps, avoiding
hands injury
Note：Turntable is always rotating clock-
wise during mounting and demounting
process, unless the machine is something
wrong or operating mistakenly, it may
rotate anticlockwise.
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.
• Check 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,
that 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 can’t make
sure of it, don’t mount the tire.
Don’t put your hands on the wheel: if you
put your hands between rim and mounting
head, it may getting hurt when operating
arm return to its original position.
Keep your hands and body as far as away
from the operating arm when rotating the
turntable, avoiding body injury.
