WHEEL CLAMPING SYSTEM
The machine self-centring chuck is operated by the high-pressure hydraulic
system with working pressure from 2 to 11 MPa. During the rotation of the
chuck the working pressure is indicated by the installed manometer. The
standard working pressure amounts to 11 MPa, but for weaker or particularly
thin rims it is recommended to limit this pressure.

ALL WORKS WITHIN THE
ELECTRICAL SYSTEM OF THE
MACHINE, INCLUDING THE
FOLLOWING ONES, MUST BE
CARRIED OUT BY
PROFESSIONALLY
QUALIFIED PERSONNEL.
Check if the main electrical supply cable
corresponds to the voltage value indicated
on the rating plate.
Connect the supply cable to the plug
according to European or domestic
standards
(Drawing
12).
The
yellow-green
conductor in the supply cable is the
protective conductor,
Check the earthing efficiency
The machine must be connected to the
supply network through а multipoint
insulating
circuit-breaker
which
is
compatible with European standards and its
‘open contact gap is not smaller than 3 mm.
Check if the multipoint circuit-breaker is
properly
connected
in
the
switchboard.
After the connection of the machine you
should
momentarily
turn
on
the
main
switch
and check the correctness of engine
rotations — should be compatible with the
direction of the arrow indicated on the
engine (Drawing 13)
In the case when the engine rotations have
the
opposite
direction
you
have
to
interchange
two
phase
conductors
in
the
supply plug.
If the machine functions іп ап abnormal
way then you should immediately turn off
the main switch (Drawing 14) and find in

DISASSEMBLY
Detach
the
tyre
edge
from
the
rim
by
means
of
the
machine
disk;
lubricate
the
tyre
and
the
rim
edges
with
a
suitable
vulcanizer
paste
(Drawing
15).
Repeat
this
operation
on
the
other
side
of
the wheel.
If
it
is
the
rim
of
а
balloon
tyre
then
you
should
continue
the
operation
of
tyre
unsticking
until
it
gets
completely
detached
from
the
rim
This
operation
is
much
easier
if
you
use
a
special
roll for tubeless tyres
ATTENTION:
If

rim
it
is
recommended
to
carry
out
this
operation
in
the
same
way
as
for
agricultural machines.
ATTENTION:
Tyre
and
rim
edges
should
always
be
very
well
lubricated
with
a
vulcanizer
paste.
ASSEMBLY
In
order
to
assemble
the
required
tubeless
tyre
you
have
to
place
the
tyre
on
the
machine
carriage,
keeping
it
inclined.
Next
you
have
to
slide
it
over
the
rim
by
means
of
а
vulcanizer
spoon
and
by
pressing
the
tyre
top
slide
it
over
the rim top.
~
If
the
above
mentioned
is
not
possible
you
have
to
use
the
vulcanizer
clamp
contained
in
a
standard
equipment
(Drawing

апа
simultaneously
slide
both
tyre
edges
over
the
rim.

ATTENTION:
For
the
assembly
of
a
particularly
hard
balloon
tyre
with
textile
cord
or
a
tubeless
tyre
with
a
very
large
rim
it
is
recommended
to
carry
out
this
operation
in
the
same
way
as
for
agricultural
machines.
WARNING!
!t
is
strictly
forbidden
to
pump
the
wheel
until
it
was
properly
mounted
on
the
assembly
machine!
Particularly
heavy
wheels
should
be
mounted
on

MACHINES
DISASSEMBLY
Mount
the
wheel
in
the
machine
self-centring
chuck
апа
lift
it
until
the
rim
touches
the
machine
disk.
After
deflating
the
tyre
start
the
process
of
unsticking
the
tyre
from
the
rim
by
means
of
a
portable
control
unit
lever
(Drawing
18
or
Drawing
15).
By
using
pedals
and
levers
of
the
portable
contro!
unit
shift
the
disk
forwards
and
keep
on
turning
the
machine
spindle
After
lubricating
tyre
and
rim
edges
with
a
special
vuleanizer
paste
put
the
wheel
into
motion.
After
termination
of
the
above
operations
withdraw
the
locking
pin
and
turn
the
tool
by
180
degrees.
Repeat
these
operations
for
the
other
side
of the
tyre.
Tilt
the
working
arm
and
return
the
disk
by
pressing
the
pedal.
By
using
the
lever
turn
the
working
tool
to
its
second
position
(to
use
claw)
and
fix
the
working
tool
to
the
carriage.
Move
the
claw from
the
portable
control
unit
to
the
tyre
and
insert
it
between
the
tyre
edge
and
the
rim
until
the
tyre
is
hooked
(Drawing
19
and
20).
Stretch
the
tyre
and
move
the
wheel
rim
away
from
the
tool
until
the
tyre
edge
creates
the
channel
between
the
tyre
and
the
rim.
Insert
the
vulcanizer
spoon
(Drawing
20/
Drawing
7)
between
the
rim
and
the
tyre
over
the
claw
so
that
the
tyre
edge
remains
hooked
by
the
claw.
Again
put
the
rim
into
motion
towards
the
tool
and
tum
it
until
it
slips
off
the
tyre.
Lean
the
wheel
against
the
platform
carriage
in
order
to
secure
the
working
space
necessary
for
easy
inner
tube
removal.
Disassembly
of
the
other
edge
should
be
carried
out
after
reversing
the
working
tool
by
180
degrees
inserting
it
(the
claw)
between
the
rim
and
the
tyre
edge
(Drawing
19)
and
turning
the
machine
spindle
clockwise
until
the
operation
is
finished.
ASSEMBLY
In order to place the tyre on the rim you should first fix
the vulcanizer clamp at the peak point of the rim
(Orawing
17/
Drawing
8)
and
place
the
tool
(the
claw)
between the tyre and the rim.
Тит the machine spindle clockwise until the back
edge of the tyre slides fully over the rim.
Introduce the inner tube inside the tyre and by leaning
the wheel against the platform carriage (Drawing 17)
support this operation.
Place the tool again in the neighbourhood of the wheel
valve
as
it
was
done
for
the
previous
side
of
the
tyre.
Place
the
vulcanizer
clamp
to
the
left
of
the
too!
