Surfaces, edges and corners Accessible parts of the compression power tools, except the inserted tool, shall not have sharp edges or angles or rough or abrasive surfaces, see 3.1 of EN 292-2:1991 5.1.2 Supporting surface and stability Compression power tools shall be so designed that they can be laid aside and remain in stable position on a plane surface 5.1.3 Position of handles Handles shall be designed to be clear from the compression area and be remotely positioned from the compression mechanism 5.1.4 High pressure ejection Hydraulic systems of the power tools shall be enclosed so as to give protection against high pressure fluid ejection 5.2 Thermal safety Surface temperatures of parts of the power tools which are held during use or could be inadvertently touched shall follow the provisions of EN 563 NOTE The limit values for low temperatures are studied by CEN/TC 122 Power tools for use in potentially explosive atmospheres should comply with EN 1127-1 However because the suitability of a power tool for use in potentially explosive atmospheres will depend not only on the power tool but the inserted tool and the workpiece, it is not possible to give any detailed advice in this standard 5.3 Noise 5.3.1 General The emission of noise from a hand-held power tool shall be kept as low as possible The noise emission from using hand-held power tools emanates from three main sources: the hand-held power tool itself, the inserted tool, the workpiece NOTE 5.3.2 Generally, the manufacturer has no possibility of influencing the noise emitted by the processed workpiece Noise emitted by the hand-held power tool The noise emitted by the hand-held power tool itself can be divided into: noise from the motor, BS EN 792-10:2000+A1:2008 EN 792-10:2000+A1:2008 (E) noise from exhaust air at pneumatic tools, vibration induced noise The noise from the exhaust of air is one major contributor of noise from pneumatic driven hand-held power tools A silencer of good design will reduce this noise The principles contained in EN ISO 11688-1 should be followed to reduce the noise emitted by the power tool NOTE The exhaust air can also be piped away in a hose away from the operator, however this method has limitations in practice Vibration induced noise can be reduced by use of acoustic isolation and vibration damping 5.4 Vibration Vibration at the handle of a hand-held power tool shall be kept as low as possible The principles contained in CR 1030-1 should be followed to reduce the vibration emitted by the power tool 5.5 5.5.1 Materials and substances processed, used or exhausted Exhaust air For compression power tools driven with compressed air the exhaust air shall be directed in such a way that it cannot cause a hazard to the operator and so that any secondary effects are minimized e.g blowing the dust and reflected air from the workpiece onto the operator 5.5.2 Lubricants Lubricants for compression power tools, specified by the manufacturer, shall not cause hazards to the operator or the environment 5.6 5.6.1 Ergonomics Design of the handle Handles and other parts used for gripping the power tool shall be designed to ensure that the operator is able to grip the compression power tool correctly and to perform the expected work Handles shall suit the functional anatomy of the hand and the dimensions of the hands of the operator population See 3.6 of EN 292-2:1991 and EN 614-1 Power tools having a mass greater than kg (including the inserted tool) shall be capable of being supported by two hands whilst being lifted or operated The surface of the handle or of the part of the power tool being gripped by the operator shall permit ventilation of the hand and give adequate friction 5.6.2 Control device The control device shall be adapted to the handle or to the part of the power tool being gripped by the operator so that it can be held comfortably in the run position For compression power tools which are normally are started frequently and often used for precision works the trigger force should be small 10 BS EN 792-10:2000+A1:2008 EN 792-10:2000+A1:2008 (E) For further information on trigger forces for control devices see EN 894-3:2000 5.6.3 Suspension device Provision shall be made, where appropriate, to enable the attachment to the compression power tool of a suspension device The fitting of a suspension device shall not introduce an additional hazard 5.7 Safety related measures and means 5.7.1 Start and stop device Compression power tools shall be equipped with a single control device to start or stop them It shall be arranged near the handle so that the operator can activate it without releasing the grip on the handles Each operation of the compression power tool shall be initiated by actuating the start and stop device which shall return to the start position before a new or a continued operation can be initiated The start and stop device shall be in the stop position or immediately move to the stop position when the compression power tool is connected to the energy supply 5.7.2 Unintentional start The start and stop device shall be so designed, positioned or guarded that the risk of unintentional start is minimized Verification shall be made according to clause 7.3 5.7.3 Two-hand control Two-hand control according to type of EN 574 shall be required for compression power tools having a stroke of more than mm, if the power tool is designed to execute a complete stroke and where the stroke cannot be interrupted by releasing the start and stop device
