This European Standard was approved by CENELEC on 2005-09-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, the Czech

Foreword
The text of EN 60335-2-77:2000 (IEC 60335-2-77:1996, modified) has been revised by WG 5,
Gardening appliances, of the Technical Committee CENELEC TC 61F, Safety of hand-held and
transportable motor-operated electric tools, with the aim to delete the non-electrical requirements and
to refer in that case to EN 836. In addition this standard has been brought in line with
EN 60335-1:2002. A first draft was submitted to the Unique Acceptance Procedure in December 2003.
A second draft was submitted to the formal vote and was approved by CENELEC as EN 60335-2-77
on 2005-09-01.
Tthis European Standard supersedes EN 60335-2-77:2000 + corrigendum December 2000.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-09-01
In this European Standard the common modifications to the International Standard are indicated by a
vertical line in the left margin of the text.
This standard has to be used in conjunction with EN 60335-1, Safety of household and similar
electrical appliances - Part 1: General requirements, and EN 836, Garden equipment - Powered
lawnmowers - Safety.
This Part 2 supplements or modifies the corresponding clauses of EN 60335-1, so as to convert it into
the European Standard: Household and similar electrical appliances - Safety - Particular requirements
for pedestrian-controlled mains-operated lawn-mowers.
When a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies as far as
is reasonable. When this standard states “addition”, “modification” or “replacement”, the relevant text
of Part 1 is to be adapted accordingly.
This European Standard has been prepared under a mandate given to CEN and CENELEC by the
European Commission and the European Free Trade Association and supports the essential health
and safety requirements of the Machinery Directive. See Annex ZZ.
Other harmonised standards referred to this European Standard are listed in Annex ZC of Part 1 and
this part. The annex lists the valid edition of those documents at the time of issue of this EN. All
references are however to be understood as references to the latest edition.
NOTE 1 The following numbering system is used
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a
replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.;
– subclauses, figures and annexes that are additional to those in the IEC standard are prefixed with the letter Z.
NOTE 2 In this standard the following print types are used:
– Requirements proper;
– Test specifications
– Explanatory matter.

1 Scope
This clause of Part 1 is replaced by:
This European Standard specifies safety requirements and their verification for the design and
construction of pedestrian controlled mains-operated electrical cylinder or rotary lawnmowers with a
rated voltage being not more than 250 V single phase.
This standard does not apply to lawn trimmers, lawn edge trimmers, lawn edgers, fail mowers, sickle-
bar mowers or agricultural mowers.
This standard is not applicable to rotary lawnmowers for which the cutting means is a generally
circular central drive unit on which is mounted, either one or more non-metallic filaments or one or
more non-metallic, pivotally mounted cutting elements. These cutting elements rely on centrifugal
force to achieve cutting, with the kinetic energy of a single cutting element not exceeding 10 J.
This document is not applicable to pedestrian controlled mains operated lawnmowers which are
manufactured before the date of publication of this document by CENELEC.
This standard does not in general take into account
– the use of appliances by young children or infirm persons without supervision,
– playing with the appliance by young children.
