27、vice brake, parking brake, and traction clutch (unless operator-presence type) shall be identified by a durable label. Universal symbols in ANSI/SAE J1362 or ISO 3767-1, -2, or -3 may be used. 4.2 Shutoff control device A shutoff control device shall be provided to stop operation of the engine (moto
28、r). This device shall require manual and intentional activation in order to restart the engine (motor). 4.3 Handle-mounted engine speed controls Handle-mounted engine speed controls shall move generally forward to increase speed, and generally rearward to decrease speed or stop. 4.4 Self-propelled m
29、owers Wheel-drive controls shall move generally opposite to the direction of mower travel in order to disengage the drive, except operator-presence controls, which may operate in any direction to disengage the drive. Wheel-drive disengaging controls shall be mounted with the control convenient to th
30、e operator while mowing. 5 Shields or guards 5.1 Power drives All power-driven shafts, chains, belts, gears, friction drivers, and pulleys shall be positioned or otherwise guarded to prevent the operators accidental contact during normal starting and operation of the machine. Rope starter pulleys ma
31、y be exposed only when starting engine. 5.2 Heat protection A guard or shield shall be provided to prevent inadvertent contact with any exposed components that are hot and may cause burns during normal starting and operation of the machine. 5.3 Fuel ignition protection Overflow gasoline shall be div
32、erted away from the muffler outlet area. 5.4 Attachment of shields or guards All shields or guards, except for those that are required to comply with 10.1.3 and 10.2.1, shall be either permanently attached or secured to prevent removal without the use of tools.

34、manufacturer, that shall be performed with the engine running. 6.2 Servicing points Access doors, shields, or guards shall be provided to prevent inadvertent operator contact with hazardous servicing points. 7 Electrical requirements 7.1 General The specifications given in this standard are not inte
35、nded to completely cover electrical requirements. There are such pronounced differences in the sizes and types of electrically driven outdoor power equipment that no materials, conductors, insulation, or other components can be specifically designated as standard. Therefore, all such items shall be
36、carefully chosen for each application, giving maximum consideration to safety, efficiency, and accessibility. For these reasons, the references to the standards and recommended practices of the Society of Automotive Engineers (SAE) in this clause should be considered as guidance in design rather tha
37、n exact conformance requirements. Any equivalent alternates will be considered acceptable. 7.2 Line voltage The electrical requirement for line voltage equipment is not covered in this standard. 7.3 Low-voltage battery-powered circuits (not including magneto grounding circuits) 7.3.1 Insulated cable
38、s Insulated cables comprising wiring circuits should be protected by rubber, plastic, nonmetallic tape, or nonmetallic braid covering capable of withstanding severe abrasion, except where otherwise protected or not in potentially abrasive contact with metal surfaces. This wiring assembly shall, wher
39、e possible, be grouped together, be properly supported, and be located so that no portion is in contact with the carburetor, metallic fuel lines, the exhaust system, moving parts, or sharp edges. Any edges of metal members subject to contact with the cables shall be rounded or protected to prevent p
40、ossible damage to the cables by cutting or abrasion. (See SAE J1127, J1128, J1292, and J2031.) 7.3.2 Battery installation The compartment for a vented storage battery shall be vented and provide for drainage of acid from the compartment. Drainage of acid from the battery in operating position shall
41、not come in contact with parts that will be critically affected in such a manner as to create a hazard. 7.3.3 Overload protection All circuits, except starting motor and ignition circuits, shall have overload protective devices on the battery-feed side of switches, except that, for two-wire, nongrou
42、nded systems, the overload protection shall be located in either line. (See SAE J156, J258, J553, J554, and J1284.)

43、03 8 7.3.4 Terminals and noninsulated electrical parts Terminals and noninsulated electrical parts shall be protected to prevent short-circuiting by the fuel can or tools during normal refueling and lubrication servicing. 8 Label durability requirements 8.1 General Required labels shall be certified
44、 by the machine manufacturer to meet the following label and durability requirements. Permanent safety signs are considered to have a reasonable life if the sign has good color and legibility for a period of at least five years. Exterior durability is based on vertical exposure tests for weatherabil
45、ity in the extreme climate of the United States, or a 2000-h carbon-arc test in accordance with ASTM G23, or a 2000-h xenon-arc test in accordance with ASTM G26. Other test methods may be used, providing the method ensures equal or superior sign durability. 8.2 Additional requirements Labels shall f
46、orm a durable bond with the base material surface and shall show no appreciable loss of adhesion or legibility during weathering exposure or exposure to spilled fuel or oil. When processed and applied in accordance with the label manufacturers recommendations, labels shall be weather resistant in ac
47、cordance with 8.1 and, following normal cleaning procedures, shall show no appreciable fading, discoloration, cracking, crazing, blistering, or dimensional change. Labels shall not curl at the edges. 8.3 Types considered durable 8.3.1 Embossed, indented, cast, or molded labels shall be considered su
48、fficient to meet the requirements of 8.1. 8.3.2 Metal plates more than 0.48 mm (0.019 in) thick with embossed or etched lettering, and fastened with rivets or equivalent fastening means, shall be considered sufficient to meet the requirements of 8.1. 8.4 Silk screening Silk screening or other types of marking, when used, shall meet the applicable requirements of 8.1 and 8.2. 9 General requirements (Blade rotation warning) An indicator of blade rotation shall be provided on mowers that operate so quietly that it may not be evident that the blades are rotating.
