4 Safety requirements and/or protective measures
4.1 General
Machines shall comply with the safety requirements andlor protective measures of this clause. In addition, the machine shall be designed according to the principles of ISO 12100 for relevant but not significant hazards which are not dealt with by this part of ISO 11680,
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 wortung procedures (see 5.1).
Except where otherwise specified in this part of ISO 11680, the safety distances specified in ISO 13857:2008. 4.2.4,1 and 4 2,43, shall be met
4.2 Hand-grips
4.2.1 RequIrements
The machine shall have a hand-grip tOt each hand. The shape and surface of the hand-grip shall be designed so as to prOvide the necessary sureness of grip, regardless of whether or not the operator wears gloves. If the hand-grip nearest the cutting attachment is an integral part of the drive-shaft tube, the diameter shall be between 20 mm and 50 mm The hand-grip length shall be at least 100 mm,
The ripping length of a bail or closed hand-grip 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 gnpplng surface.
42.2 Verification
The design and dimensions shall be verified by inspection and measurement,
4.7 EngIne startIng device
4.7.1 Requirements
The engine startmg device shal be a self-contained, battery-powered electric starter and/or a manual starter where the actuator is permanently attached to the machine.
Pole-mounted powered pruners with a manual starter shall have a recoil device for the rope.
Two or more separate and disswnilar actions shall be requied to activate the electrical starting device.
4.7.2 V.rlflcatlon
The means of starling the engine shall be verified by inspection and functional testing.
4.8 Engine stopping device
4.8.1 Requirements
The machine shall be fitted with an engine stopping device by which the engine can be brought to a final stop and witidi does not depend on sustained manual effort for Its operation. The control for this device shall be so positioned that It can be operated while the machine Is held with both hands by an operator weanng gloves The colour of the control shall clearly contrast with the background.
4.8.2 VerIfication
The correct functioning of the engine stopping device shall be verified by mspection while the machine Is being operated. The location of the control shall also be verified by inspection.
4.9 Throttle control
4,9.1 PosItion
4.9.1.1 Requirements
The throUle trigger shall be positioned so that It can be pressed and released with a gloved hand while both handgrips are being held.
4.9.1.2 Verification
The position shal be verified by inspection and functional testing.
4.9.2 OperatIon
4.9.2.1 Requirements
The machine shall be provided with a throttle trigger that, when released, automatically reverts to the idling position unless a throttle lock to aid starting is engaged (see 4.9.3). The throttle trigger shal be retained in the idling position by the automatic engagement of a throttle trigger lock-out.
