Garden machinery - Hand-held chain-saws with lithium-ion
battery as power source
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.

3 Terms and definitions
The terms and definitions, which are defined in GB/T 18960, as well as the following
terms and definitions, apply to this document.
3.1
Nominal voltage
The product of the nominal voltage of a single cell and the number of cells in series.
Note: The unit is volts.
3.2
Cutting efficiency
Under the load of the rated output state, the area of the standard test material, which
is cut by the lithium-ion chain-saw per unit time.
Note: The unit is square centimeters per second.
3.3
Net mass of the machine
In the working state, the mass of the lithium-ion chain-saw, including the guide plate
and saw chain as specified in the installation instructions, the pluggable adaptable
battery pack (except for the split battery pack, which is connected to the whole
machine by a flexible cord), without the knife cover and lubricating oil.
4 Model preparation method
4.1 The model preparation method of lithium-ion chain-saw shall be carried out, in
accordance with the provisions of LY/T 1621.
4.2 The lithium-ion chain saw takes the nominal voltage of the battery pack as the main
power parameter, takes the effective length of the longest guide plate as the main
parameter of the product. The model preparation method is as shown in Figure 1:
h) Maximum linear speed of saw chain, m/s;
i) Cutting efficiency, cm2/s;
