This European Standard was approved by CENELEC on 2000-08-01. 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, Czech
Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This European Standard has been prepared by the Technical Committee CENELEC TC 61F, Hand-held
and transportable electric motor operated tools. The text of the draft was submitted to the Unique
Acceptance Procedure (UAP) in July 1994 and was approved by CENELEC as EN 50144-2-15 on
1995-03-06.
A draft for an amendment was submitted to UAP in August 1999 and was approved by CENELEC on
2000-08-01 for inclusion into a second edition of EN 50144-2-15.
This European Standard supersedes EN 50144-2-15:1997
The following dates were fixed:
- latest date by which the EN has to be implemented
at a national level by publication of an identical
national standard or by endorsement (dop) 2001-10-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2003-08-01
This standard is divided into two parts:
Part 1: General requirements which are common to most hand-held electric motor operated tools (for the
purpose of this standard referred to simply as tools).
Part 2: Requirements for particular types of tool which either supplement or modify the requirements
given in Part 1 to account for the particular hazards and characteristics of these specific tools.
This European Standard has been prepared under a mandate given to CEN/CENELEC by the European
Commission and the European Free Trade Association and supports the essential health and safety
requirements of the Machinery Directive.
Compliance with the clauses of Part 1 together with this Part 2 provides one means of conforming with
the essential health and safety requirements of the Directive.
For noise and vibration this standard covers the requirements for their measurement, the provisions of
information arising from these measurements and the provisions of information about the personal
protective equipment required. Specific requirements for the reduction of the risk arising from noise and
vibration through the design of the tool are not given as this reflects the current state of the art.
As with any standard, technical progress will be kept under review so that any developments can be
taken into account.
Warning: Other requirements and other EC Directives can be applicable to the products falling
within the scope of this standard.
This standard follows the overall requirements of EN 292-1 and EN 292-2.
Subclauses, tables and figures which are additional to those in Part 1 are numbered starting from 101.
NOTE In this European Standard the following print types are used:
- Requirements proper;
- Test specifications;
- Explanatory matter.

1 Scope
This clause of Part 1 is applicable except as follows:
1.1 Addition:
This standard applies to hedge trimmers which are designed for use by one operator, for trimming
hedges and bushes utilizing one or more linear reciprocating cutter blades.
This standard is not applicable to hedge trimmers with a rotating blade or hedge trimmers powered by
back-pack or other external source.
This standard does not give requirements for the design of the tool to reduce the risks arising from noise
and vibration.
2 Definitions
This clause of Part 1 is applicable except as follows:
2.2.18 Replacement:
2.2.18 normal load: Continuous operation with no external load applied, the cutting device being
adjusted as for normal use. The normal load is based on the rated voltage or upper limit of the rated
voltage range.
Addition:
2.2.101 blade tooth: The part of the cutter blade which is sharpened to perform the shearing action. See
Figure 101.
2.2.102 cutter blade: The part of the cutting device having blade teeth which cut the hedge by shearing
action either against other blade teeth or against an unsharpened shear plate. See Figure 101.
2.2.103cutting device: The part of the assembly of cutter blade and shear plate or the cutter blade
together with any supporting part, which performs the cutting action. See Figure 101. This may be either
single or double sided.
2.2.104 cutting length: The effective cutting length of the cutting device measured from the inside edge
of the first blade tooth or shear plate tooth to the inside edge of the last blade tooth or shear plate tooth,
see Figure 102. Where both blades move the measurements shall be taken when the first and last teeth
are furthest apart.
2.2.105 front handle: A handle located at or towards the cutting device. See Figure 103.
2.2.106 rear handle: A handle located furthest from the cutting device. See Figure 103.
2.2.107blade control: A device activated by the operator’s hand or fingers for controlling the cutter
blade movement.
2.2.108 blunt extension: A blunt part of the cutting device or a part of an unsharpened plate fitted to the
cutting device which extends beyond the blade teeth. See Figure 101.
2.2.109 run-down time: The elapsed time from the release of the blade control until the cutter blade
stops.
2.2.110maximum speed: The highest motor speed obtainable when adjusted in accordance with the
manufacturer’s specifications and/or instructions and with the cutting device engaged.
