SIST EN 13525:2005
EN 13525:2005 (E)
4.2 Operator controls
4.2.1 General
All machines shall have separate controls for starting/stopping the chipping components and for
starting/stopping the infeed action meeting the requirements given below in 4.2.2, 4.2.3, 4.2.4. The safety and
reliability of control system shall meet the requirements given in 4.2.5. Controls for stopping the chipping
components shall also stop the infeed action.
4.2.2 Starting the machine
4.2.2.1 Where the machine is powered by an external power source, e.g. a tractor power take-off or a
hydraulic system, the tractor power-take-off start control or hydraulic system control is regarded as the
operator's control for starting the chipping components, infeed components and integral conveyors (where
fitted).
4.2.2.2 Where the machine is powered by an integral power source, e.g. an internal combustion engine
or an electric motor, the engine or motor start is regarded as the operator's control for starting the chipping
components, infeed components and integral conveyors (where fitted).
4.2.2.3 Where an electric starter is used to start the integral power source, unauthorised activation of the
starter shall be avoided by using one or more of the following methods:
a key operated ignition or starting switch;
a lockable cover for the ignition or starting switch;
a security ignition or starting lock;
a lockable battery disconnection switch.
4.2.3 Stopping the machine
4.2.3.1 Where the machine is powered by an external power source, e.g. tractor power take-off or
hydraulic system, the external power source stopping controls such as the tractors engine stop control, the
tractor power take-off control or hydraulic system control are regarded as the operator's control for stopping
the machine.
4.2.3.2 Where the machine is powered by an integral power source, e.g. an internal combustion engine
or electric motor, the engine or motor stop is regarded as the operator's control for stopping the machine.
4.2.3.3 Where integral power source is an internal combustion engine, the engine stop control shall not
require sustained manual pressure for its operation and when once actuated it shall not be possible to restart
the engine unless the control has been reset.
4.2.4 Infeed stop control
4.2.4.1 General
All machines shall have an infeed stop control. The design, position and function of the infeed stop control
shall allow the operator when in the designated operating position, if entangled in the wood being fed into the
machine, to stop the infeed action. The operator shall be able to engage the infeed stop control, in the
direction of infeed, by using parts of the body other than just the hands (e.g. shoulder, elbow, torso, hip, legs
etc.). To achieve this, it shall meet the positional requirements given in 4.2.4.2 and functional requirements in
4.2.4.3.

---------------------- Page: 11 ----------------------
SIST EN 13525:2005
EN 13525:2005 (E)
Whilst these requirements shall be fulfilled, the design, position and function of the infeed stop control shall
seek to minimise inadvertent activation (nuisance tripping) by wood and branches as they are fed into the
machine; and opportunities for the operator to remove, disconnect, disable, defeat, or jam the control.
4.2.4.2 Positional requirements
4.2.4.2.1 The infeed stop control shall be located in accordance with either 4.2.4.2.2, see Figure 2 or
4.2.4.2.3, see Figure 3, as appropriate to the height of the outermost lower edge of the infeed chute. At the
infeed chute vertical edges, the infeed stop control shall cover a minimum of 0,75 x h. At the relevant
horizontal edge, top or bottom, the infeed stop control shall cover the entire width of the edge.
4.2.4.2.2 For type A machines, the infeed stop control shall be located at the sides and at the lower edge of
the chute, see Figure 2.

4.2.4.2.4 In either location, the position of the infeed stop control in relation to the outermost edge of the
infeed chute shall be in accordance with the appropriate Figure 4 or Figure 5 such that:
all positions of the infeed stop control that allow or cause infeed action are in front of the outermost edge
of the infeed chute, i.e. zone B;
10
---------------------- Page: 12 ----------------------
SIST EN 13525:2005
EN 13525:2005 (E)
from those positions, the infeed stop control shall be able to be moved to a position known as the
‘emergency stop position’, i.e. position C; and
this emergency stop position is in the position closest to the outermost edge of infeed chute but
sufficiently in front of that edge for the emergency stop position to be successfully engaged, i.e. the
respective operation completed, by the operator in the manner described in 4.2.4.1 in the event of
entanglement.
4.2.4.2.5 The positions/functions of the infeed stop control shall be clearly indicated on both sides of the
infeed chute and also in the instruction handbook. The colour of the infeed stop control shall be preferably red
or yellow. Where other colours are used, they shall be bright and in contrast to the background colour of the
infeed chute.
4.2.4.2.6 In the case of machines with an integrated feed conveyor, the infeed stop control shall meet the
requirements of 4.2.4.2.4. Instead of meeting the location requirements of 4.2.4.2.1 the infeed stop controls
shall be provided at the sides and at the outer end of the conveyor. Any reverse action of the conveyor shall
have a hold-to-run control located within reach of the operator but outside of reach to the danger zones and in
a position providing good visibility of the conveyor and the infeed components.

4.2.4.3 Functional requirements
4.2.4.3.1 All machines shall comply with 4.2.4.3.2 to 4.2.4.3.6 inclusive. Type B machines shall also meet
the requirements of 4.2.4.3.7. Where the infeed stop control incorporates other functions for controlling the
infeed components, they shall meet the appropriate requirements of 4.2.4.3.8 to 4.2.4.3.10.
4.2.4.3.2 Actuation of any part of the infeed stop control shall have the same functional result.
4.2.4.3.3 Movement of the infeed stop control from zone B to position C, as defined in 4.2.4.2.4, shall stop
infeed action. Actuation to the emergency stop position shall have priority over any other controls used to
operate the infeed components as defined in 4.2.4.3.6.
4.2.4.3.4 The force required to actuate the infeed stop control from zone B to position C (see Figures 4 and
5) shall not exceed 150 N on the horizontal part of the infeed stop control (including those provided on
machines with an integrated feed conveyor) and 200 N on other parts along the length 0,75 x h as specified in
4.2.4.2.1. The force required shall be measured in a horizontal direction ±15°, or in the case of a pivoting
infeed stop control, in the tangential direction of its movement.
4.2.4.3.5 On actuation of the infeed stop control to position C, the time taken for infeed action to stop shall
be as short as practicable and in all instances less than the minimum time for wood to travel from the nearest
position of the infeed stop control to the reference plane.

EN 13525:2005 (E)
4.2.4.3.6 When actuated to position C, the operator shall not be able to restart infeed action by solely
returning the infeed stop control to any position in zone B. The operator shall only be able to restart infeed
action by deliberate actuation of a separate control provided for this purpose.
4.2.4.3.7 In addition to meeting the requirements of 4.2.4.3.2 to 4.2.4.3.6, for type B machines the infeed
stop control shall stop or reverse infeed action when pulled to its outermost position against the direction of
feed, i.e. to position H.
4.2.4.3.8 Where the infeed stop control incorporates a control position for reversing the infeed action, the
operation of that function shall be hold-to-run if it is behind the outermost edge of the infeed chute, i.e. at
position E, see Figure 4 or Figure 5 as appropriate. Position E shall be as close as possible to the outermost
