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.

visually

if

the

machine

is

complete

and

without

damage.

If

you

have

any

doubts

then

you

should

not

use

the

machine

and

inform

it

the

producer's

or

distributor's

qualified

personnel

WARNING!

The

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

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

then

you

should

immediately

turn

off

lift

it

until

the

rim

touches

the

of

unsticking

the

tyre

from

the

rim

by

means

of

a

portable

control

unit

lever

(Drawing

By

using

pedals

and

levers

of

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

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
