6.1.1 Checking the battery
Purchase the battery with the capacity that most
suits your operational requirements and fully
charge it according to the instructions in the
battery booklet.
The list of approved batteries for this machine is

IMPORTANT During the first period of use
(or after replacing the chain) it must be checked
more frequently due to settling of the chain.
