Summary This standard specifies the safety requirements and test methods for the design, construction and use of portable knapsack powered brush and lawn mowers powered by an internal combustion engine and transmitting mechanical power to the cutting attachment. This standard specifies the methods to eliminate or reduce the various hazards caused by the use of the whole machine, and specifies the requirements for the relevant information on safe operation provided by the manufacturer. This standard and the relevant sections of Part 1 (see 4.1) deal with all serious hazards, hazardous situations and critically hazardous events associated with the whole machine during normal use and reasonable, foreseeable misuse of the machine by the manufacturer. Whole body vibration hazards caused by powered units are excluded. This standard applies to products produced after its implementation. This standard does not apply to machines with non-integral metal blade construction

1 Scope

This part of GB/T 19725 specifies a portable piggyback power that uses an internal combustion engine as the power source and transmits mechanical power to the cutting accessory Safety requirements and test methods for the design, structure and use of brush cutters and lawn mowers. This section proposes to eliminate or reduce the use of integral The methods of various hazards produced by the machine stipulate the requirements of the relevant materials for safe operation provided by the manufacturer. The relevant chapters of this part and part 1 (see 4.1) refer to the normal use and reasonable, foreseeable manufacturer misuse of the whole machine All serious hazards, dangerous situations and serious hazard events related to the whole machine, except for the whole-body vibration hazard caused by the backpack-type power plant. Note 1. There is currently no standard test procedure for measuring the whole body vibration caused by the piggyback power plant. Note 2. For a list of serious hazards, see Appendix A and Appendix C of GB/T 19725.1-2020. This section applies to products produced after its implementation. This section does not apply to the installation of non-integral metal blade structure of the machine, such as chain swing or knife blade.
