5.3.5. Turning the tool on and turning it off
ATTENTION! Before turning on the tool for the first time after
it has been stored for a long time or transported, it is necessary to fully
charge the battery cell (see Supplement 4). Only after having charged
the battery the tool may be turned on. Otherwise, the tool cannot be
switched on or it can switch off immediately after having been turned
on. But this does not mean that the tool has any default.
