Introduction

This document defines the specific safety requirements for machines for mounting and demounting

vehicle tyres. It examines all the main hazards and the hazard situations and conditions relating to the

type of machine in question, when used as indicated by the manufacturer or in improper conditions

reasonably foreseen by the manufacturer. The document defines the necessary technical measures for

eliminating or reducing risks caused by significant hazards or danger situations and conditions during

transport, use and maintenance.
This document is type “C”, as defined in EN ISO 12100:2010.

When provisions of this C-type standard are different from those which are stated in A or B standards,

the provisions of this type C standard take precedence over the provisions of the other standard for

machines designed and built according to the provisions of this C standard.

The type of machine in question, and the degree to which the hazards and danger situations/events, are

indicated in the “aim and application” section of this document.

1 Scope

This document specifies the safety requirements and their verification for the design and building of

machines (see the definition in 3.1) for mounting and demounting tyres on the vehicles listed below and

identified according to the international categories M1, M2, N1, O1, O , L4 and L5:

a) cars
b) buses
c) lorries
d) motor-vehicles for specific or special transport
e) mobile homes
f) cargo trailers
g) car trailers
h) motorised quadricycles
i) motor vehicles
j) mopeds

k) agricultural machines (if the wheel/tyre dimensions are compatible with the maximum dimensions

indicated in the tyre changer user instructions)

The vehicles listed in points a) to f) have an overall full-load mass no greater than 3,5 t.

These machines are designed to ensure the tyre is correctly fitted on the wheel in safe conditions. The

document describes how to eliminate or reduce the risks resulting from the foreseen use (or improper

but reasonably foreseeable use) of these machines by the operator during normal operation and service.

In addition, it specifies the type of information that the manufacturer will supply with regard to safe

working procedures.

The document describes all the significant hazards (as listed in Table 1) and the danger situations and

events relating to these machines.

This document does not apply to hazards regarding maintenance or repairs carried out by professional

maintenance personnel.

This document does not apply to automatic machines (machine, which, after initiation of start by the

operator, is capable of independently perform one or more defined sequences of movements that lead to

the complete assembly and disassembly of the tyre from the wheel. The operator has the task of

supervising the process by intervening, if necessary).
This document does not cover the reliability of control circuits.

This document does not cover the risk of mechanical failure in operating conditions.

This document does not apply to machines manufactured before its date of publication.

Introduction

This document defines the specific safety requirements for machines for mounting and demounting

vehicle tyres. It examines all the main hazards and the hazard situations and conditions relating to the

type of machine in question, when used as indicated by the manufacturer or in improper conditions

reasonably foreseen by the manufacturer. The document defines the necessary technical measures for

eliminating or reducing risks caused by significant hazards or danger situations and conditions during

transport, use and maintenance.
This document is type “C”, as defined in EN ISO 12100:2010.

When provisions of this C-type standard are different from those which are stated in A or B standards,

the provisions of this type C standard take precedence over the provisions of the other standard for

machines designed and built according to the provisions of this C standard.

The type of machine in question, and the degree to which the hazards and danger situations/events, are

indicated in the “aim and application” section of this document.

1 Scope

This document specifies the safety requirements and their verification for the design and building of

machines (see the definition in 3.1) for mounting and demounting tyres on the vehicles listed below and

identified according to the international categories M1, M2, N1, O1, O , L4 and L5:

a) cars
b) buses
c) lorries
d) motor-vehicles for specific or special transport
e) mobile homes
f) cargo trailers
g) car trailers
h) motorised quadricycles
i) motor vehicles
j) mopeds

k) agricultural machines (if the wheel/tyre dimensions are compatible with the maximum dimensions

indicated in the tyre changer user instructions)

The vehicles listed in points a) to f) have an overall full-load mass no greater than 3,5 t.

These machines are designed to ensure the tyre is correctly fitted on the wheel in safe conditions. The

document describes how to eliminate or reduce the risks resulting from the foreseen use (or improper

but reasonably foreseeable use) of these machines by the operator during normal operation and service.

In addition, it specifies the type of information that the manufacturer will supply with regard to safe

working procedures.

The document describes all the significant hazards (as listed in Table 1) and the danger situations and

events relating to these machines.

This document does not apply to hazards regarding maintenance or repairs carried out by professional

maintenance personnel.

This document does not apply to automatic machines (machine, which, after initiation of start by the

operator, is capable of independently perform one or more defined sequences of movements that lead to

the complete assembly and disassembly of the tyre from the wheel. The operator has the task of

supervising the process by intervening, if necessary).
This document does not cover the reliability of control circuits.

This document does not cover the risk of mechanical failure in operating conditions.

This document does not apply to machines manufactured before its date of publication.
