Accessible parts of small circular, small oscillating and reciprocating saws, 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 Small circular, small oscillating and reciprocating saws shall be so designed that they can be laid aside and remain in stable position on a plane surface 5.1.3 Flanges Flanges for small circular saws, for clamping the saw blade to the working spindle shall be of equal size and of a size not less than 0,3 times the rated diameter of the blade 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 5.1.5 Guide plate Small circular saws and jig saws shall have a guide plate affixed to the saw of a size and shape to permit the intended operation of the saw Power hack saws shall have a guide plate to absorb the reaction force from the sawing process 5.1.6 Run-down time Small circular saws shall have a run-down time after stop command has been given within s 5.1.7 Guard Small circular saws shall be provided with a guard above the guide plate to prevent unintentional contact of hands with the inserted saw blade It shall not be possible to remove the guard without the aid of a service tool Small circular saws with a sawing depth of more than 10 mm shall be provided with a moveable (retractable) guard covering the part of the blade protruding below the guideplate The moveable guard shall move freely without jamming When released from its full open position, it shall return to the fully closed position in 0,3 s Reciprocating saws not require a guard for the part of the saw blade which performs the sawing and is situated below the guide plate The part of the saw blade which is situated above the guide plate shall be protected by guard or the design shall be so that the risk of contact with the teeth of the blade and with moving parts of the mechanism is prevented NOTE Oscillating saws not require a guard BS EN 792-12:2000+A1:2008 EN 792-12:2000+A1:2008 (E) 5.1.8 Riving knife Small circular saws intended for cutting wood shall be provided with a riving knife The riving knife shall not be thicker than the width of the cutting groove nor thinner than the saw blade body For more detailed specifications see EN 50144-2-5 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, 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 10 BS EN 792-12:2000+A1:2008 EN 792-12:2000+A1:2008 (E) 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 small circular, small oscillating and reciprocating saws driven with compressed air the exhaust air or gases 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 Dust It shall be possible to connect to circular saws a dust collecting device or to use a dust suppression device 5.5.3 Lubricants Lubricants for small circular saws, 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 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 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 5.7 5.7.1 Safety related measures and means Start and stop device Small circular, small oscillating and reciprocating saws 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 The start and stop device shall be so designed that the inserted tool ceases to be powered when the start and stop device is released Without manual effort it shall, when released, move to the stop position, i.e be of the type "hold to run" The start and stop device shall be in the stop position or immediately move to the stop position when the power tool is connected to the energy supply It shall not be possible to lock the start and stop device in the running position 11 BS EN 792-12:2000+A1:2008 EN 792-12:2000+A1:2008 (E) 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 The start and stop device for small circular and reciprocating saws shall be designed with two separate and dissimilar actions to start it Information for use 6.1 Marking, signs and written warnings !Small circular, oscillating and reciprocating saws be marked
