19.101 Saw blade barrier 1) For jig saws A barrier shall be provided to prevent inadvertent contact with the cutting edge of the saw blade above the plane of the base plate and from the front of the tool. The barrier shall not prevent the visual observation of the saw blade in contact with the workpiece. Compliance is checked by inspection and by the following test. The jig sawis setforthe right-angledcut. The testprobe ofFigure 101 a) is advancedin anysingle plane perpendicular to the saw blade and parallel to and above the plane ofthe base plate as shown in Figure 101 b) andFigure 101 c). The longitudinalaxis ofthe testprobe shallbe perpendicularto the toothededge ofthe saw blade. The test probe shall be equally shared about the central plane ofthe saw blade. When the test probe is moved towards the saw blade, it shall not be able to touch its toothed edge. 2) For other types of reciprocating saws If a reciprocating saw is designed with a grip zone adjacent and behind the saw blade, a barrier shall be provided to prevent inadvertent contact with the teeth of the saw blade in any saw blade position in accordance with 8.14.2 b) 103). The barrier shall: – be located between the grip zone and the teeth of the saw blade; – have a minimum height of 6 mm above the grip surface; and – extend a minimum of 6 mm on either side of the teeth of the saw blade. A barrier is not required if the tool is supplied with an auxiliary front handle. Compliance is checked by inspection and by measurement. 20 Mechanical strength This clause of Part 1 is applicable. 21 Construction This clause of Part 1 is applicable except as follows: 21.18.1 Addition: For jig saws, power switches other than momentary power switches are permitted. 22 Internal wiring This clause of Part 1 is applicable.
