44、 of pulleys, discs,drums, sprockets, and gears shall be guarded by location orotherwise guarded to prevent inadvertent contact by the opera-tor, and passenger on two seat karts, during normal seating,starting of the engine, and operation of the kart.A component will be considered sufficiently guarde
45、d if itcannot be contacted with probe as shown in Fig. 3 when testedin accordance with 10.1.4.1.These guarding requirements do not pertain to contactduring maintenance activities.These guarding requirements are in addition to the hairentanglement test set out in 10.1.5.10.1.4.1 (WarningThe following
46、 procedures should notbe conducted with the engine running.) Insert the probe (seeFig. 3) into all openings to its maximum depth (4 in. (102 mm)or until a force of 1 lb (4.5 n) is attained. As the probe isinserted, rotate and position it in all possible angles within theopening, attempting to contac
47、t the part or parts under test. Thefinger probe shall not be inserted beyond the length of theprobe (4 in. (102 mm). Probe cannot contact any rotatingcomponent.10.1.4.2 The hazards shall be considered “guarded by loca-tion” if one of the following applies:(1) The hazard is covered by other parts or
48、components ofthe kart, or because of its location, cannot be contacted with thefinger probe shown in Fig. 3 (see ANSI/OPEI B71.1, 1998)while maneuvering the probe in any manner; or(2) The hazard is under and within the perimeter of thechassis components, such that the hazard cannot be reachedwith th
49、e finger probe shown in Fig. 3 (see ANSI/OPEI B71.1,1998) while maneuvering the probe as follows:(a) From above the chassis, downward through openingsin or between the components; and(b) Underneath the chassis components, allowing onlyhorizontal or downward probe movement, or both.(3) The hazard does not rotate when the kart is stationary andthe operator, and passenger in a two seat kart, cannot reach thehazard while in a Normally Seated Position (see Note 1 andNote 2).NOTE 1The entanglement test set out in 10.1.5 must also be compliedwith.NOTE 2Norm
