LY/T 3022-2018Garden machinery - Hand-held chain-saws with lithium-ion battery as power source (English PDF)

1 Scope

This standard specifies the terms and definitions, model preparation methods, basic parameters, technical requirements, test methods, signs, instruction manuals, packaging, transport, storage, handling of hand-held chain-saws with lithium-ion battery as power source (hereinafter referred to as chain-saws with lithium-ion battery).

This standard applies to hand-held chain-saws, which are operated by a single person, for sawing branches, wood and similar materials; are powered by a rechargeable lithium-ion battery pack (battery pack) with a nominal voltage not greater than DC 75V, under normal environmental conditions.

This standard does not apply to.

- Lithium-ion chain-saws for one-handed operation and/or for use at heights, such as in trees;

- Hand-held chain-saws, which are powered by user-installed universal battery packs or battery packs;

- Other hand-held chain-saws, which are powered by non-lithium-ion batteries.
