Using booster batteries
Booster batteries are used if the carrier batteries are too
flat or cold to start the carrier normally.
CAUTION: Before boost-starting the carrier, shut
it down properly to prevent unexpected machine
movement when the engine starts.
CAUTION: An explosive gas is produced while
batteries are in use or being charged. Keep
flames or sparks away from the battery area.
Make sure that the batteries are charged
in a well-ventilated area.
IMPORTANT: Always disconnect the controller before
using booster batteries, otherwise severe
controller damage could occur.

cable between the two carrier batteries (A).
