This European Standard was approved by CENELEC on 1998-10-01. 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 February 1994 and was approved by CENELEC as EN 50144-2-14 on
1994-10-04.
A draft for an amendment was submitted to UAP in April 1994 and was approved by CENELEC on
1994-10-04 for inclusion into the European Standard.
A further amendment was submitted to UAP in May 1996 and was approved by CENELEC as
amendment A1 to EN 50144-2-14 on 1996-12-09.
Amendments to fulfill the essential requirements of the Machinery Directive were submitted to the formal
vote in June 1998 and were approved by CENELEC on 1998-10-01 for inclusion, together with the earlier
amendment, into a second edition of EN 50144-2-14.
This European Standard supersedes EN 50144-2-14:1996.
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with the EN have to be withdrawn (dow) 2001-12-01
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 provision of
information arising from these measurements and the provision 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.
CEN TC/255 is producing standards for non-electrically powered tools.
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:
Addition:
This standard applies to planers with a cutting width up to 150 mm.
This standard does not give requirements for the design of the tool for the reduction of the risk 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: The load obtained when the planer is operated continuously, the load being such
that the input, in watts, is equal to rated input.
The normal load is based on the rated voltage or on the upper limit of the rated voltage range.
Additional definition:
2.2.101 cutting head: The assembly of blades, drums, blade fixing elements, relevant screws and
spindle, the whole being ready for working.
3 General requirements
This clause of Part 1 is applicable.
4 General conditions for the tests
This clause of Part 1 is applicable except as follows:

This clause of Part 1 is applicable except as follows:
7.1 Addition:
Planers shall be marked with:
— the rated no-load speed in revolutions per minute where the rated no-load speed is the speed
measured on the cutting head obtained after the planer has been running idle for 10 min;
— a clear indication of the direction of rotation of the cutting head by means of an arrow, raised or
sunk, or by any other means no less visible and indelible.
7.13.1 Addition:
The instructions sheet shall also contain the following information:
— instructions for the fitting of the blades and their adjustment to the correct position;
— types of cutting heads which can be used;
— information on the correct use of the dust collection equipment.
