Scope

This part of GB 20888 specifies the design and structural safety of pole-type knapsack power pruning saws (hereinafter referred to as "knapsack pruning saws") with a knapsack power device and the power source transmits power to the cutting parts through the drive shaft. Requirements and test methods. Cutting components in this section refer to saw chains and saw blades that reciprocate or rotate. This section proposes ways to eliminate or reduce various hazards caused by the use of knapsack pruning saws, and specifies the information requirements for safe operation provided by the manufacturer. This part and the relevant chapters of Part 1 deal with all the serious hazards associated with the knapsack pruning saw during normal use and reasonably foreseeable misuse, but do not involve the electric shock hazard caused by contact with overhead cables (use warnings and recommendations contained in the instruction manual) and whole-body vibration hazards from backpack-mounted power units. This section applies to products produced after its promulgation and implementation.
