The jig saw is set for the right-angled cut. The test probe of Figure 101a) is advanced in any single plane perpendicular to the saw blade and parallel to and above the plane of the base plate as shown in Figure 101b) and Figure 101c). The longitudinal axis of the test probe shall be perpendicular to the toothed edge of the saw blade. The test probe shall be equally shared about the central plane of the 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 board shall be supported on resilient material and fixed vertically by screws, clamps,air cylinders or the like to a test rig, see Figure 1.102.
In all cases, the board excess end shall be approximately 250 mm from the clamp and shall be readjusted at the beginning of each series of tests, which consists of five test cycles.
During the entire cut, the saw blade shall be perpendicular to the board.New saw blade for the entire series of tests as specified for sawing chipboard. The saw blade used shall be recorded.
Pendulum systems, if any, being set as specified by the manufacturer for cutting chipboard.If not specified by the manufacturer, pendulum systems are set to maximum. For sabre saws, the guide plate shall be fitted.AS NZS 62841.2.11 pdf free download.
