INTERNATIONAL STANDARD ISO 11680-1:2021(E)
Machinery for forestry — Safety requirements and testing
for pole-mounted powered pruners —
Part 1:
Machines fitted with an integral combustion engine
1 Scope
This document specifies safety requirements and measures for their verification for the design and
construction of portable, hand-held, pole-mounted powered pruners (hereafter named “machine”),
including extendable and telescopic machines, having an integral combustion engine as their power
source. These machines use a power transmission shaft to transmit power to a cutting attachment
consisting of a saw-chain and guide bar, a reciprocating saw blade or a single-piece circular saw blade
with a 205 mm maximum outside diameter. Methods for the elimination or reduction of hazards arising
from the use of these machines and the type of information on safe working practices to be provided by
the manufacturer are specified.
This document deals with all significant hazards, hazardous situations or hazardous events with the
exception of electric shock from contact with overhead electric lines (apart from warnings and advice
for inclusion in the instructions), relevant to these machines when they are used as intended and under
conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).
This document is applicable to portable, hand-held, pole-mounted powered pruners manufactured after
its date of publication.
Brush cutters with a circular saw blade are not included in the scope of this document.
NOTE Brush cutter requirements are outlined in ISO 11806-1:2021.

4 Safety requirements and/or protective measures
4.1 General
Machines shall comply with the safety requirements and/or protective measures of this clause. In
addition, the machine shall be designed according to the principles of ISO 12100:2010 for relevant but
not significant hazards which are not dealt with by this document.
The safe operation of a pole-mounted powered pruner also depends on the safe environment associated
with the use of personal protective equipment (PPE), such as gloves, slip-resistant footwear, and eye,
hearing and head protective equipment, as well as safe working procedures (see 5.1).
4.2 Protection against contact with power driven components
4.2.1 Requirements
All power driven components with the exception of the cutting attachment, shall be located or guarded
so that the operator will not inadvertently contact them when starting or during normal operation of
the machine as described in the instructions.
4.2.2 Verification
The location and accessibility of power driven components shall be verified by inspection. For straight
line access, the safety distances specified in ISO 13857:2019, 4.2.4.1 and 4.2.4.3 shall be met. For other
access points, use probe B of IEC 61032:1997, shown in Figure 2. The probe shall be applied to any
opening protecting a power-driven part using a force of (10 ± 2) N. Contact with any power driven
component is not allowed.

ISO 11680-1:2021(E)
4.3 Handles
4.3.1 Requirements
The machine shall have a handle for each hand. The shape and surface of the handle shall be designed
so as to provide the necessary sureness of grip, regardless of whether or not the operator wears gloves.
If the handle nearest the cutting attachment is an integral part of the drive-shaft tube, the perimeter of
the handle cross-section along the gripping length shall be between 65 mm and 170 mm. The gripping
length shall be at least 100 mm.
The gripping length of a bail or closed handle shall comprise any length that is straight or curved at a
radius greater than 100 mm together with any blend radius, but not more than 10 mm, at one or both
ends of the gripping surface.
4.3.2 Verification
The design and dimensions shall be verified by inspection and measurement.
4.4 Harness
4.4.1 Requirements
All machines with a dry weight of more than 6 kg shall be equipped with a harness to be worn by the
operator. The harness is primarily for supporting the machine during movement between cutting tasks
and for reducing the risk of unintentional contact with the cutting attachment. The harness shall be
adjustable to the size of the operator.
Shoulder harnesses shall be:
— designed in a way for easy removal; or
— equipped with a quick release mechanism that ensures that the machine can be removed or released
quickly from the operator.
A single shoulder harness is considered to be designed in a way for easy removal.
A double shoulder harness is considered to be designed in a way for easy removal, if the left and right
shoulder straps are not connected to each other in front of the operator’s body.
If straps to connect the left and right shoulder straps are provided, it is also considered to be designed
in a way for easy removal when the straps connecting the left and right shoulder straps can be released
under the load of the machine by using one hand and have no more than two release points.
