COOLING SYSTEM

The cells performance is dependent on the temperature
as indicated in the above image. The critical behaviors are
recorded at low temperatures, At these temperatures the
cells performance decreases. Park the machines with bat-
teries charged.
NOTE: Do not park the machine with flat batteries. The cells
can lose a small quantity of charge capacity. This can
lead to an increase in charging time during reigni-
tion and the charge level will be very low. In such
condition, if external temperatures are below 0°C,
charging time of cells will increase as compared to
the standard time with completely flat batteries
and temperature above 0°C.

The optimal solution in cases of very low temperature is to
use the platform for a few minutes before the charge to
heat the battery pack and reduce the charging times or
charge the machine after having completed work when
the battery pack is still warm. It is important to store the
machine with some charge remaining in the battery.
There will not be any problems if the battery is completely
discharged, but it will require longer time during charge
cycle. There is a self cooling system in case of high temper-
ature which is described later.
When temperature of any cell is below 0 °C (32 °F), the
machine will recover in the low speed function; then the

Case Cooling Air Flow

MAF11630
The case of the lithium battery pack has a cooling system
(see figure above). The fan no. 1 pulls the fresh air and
pushed through the bottom case. The fresh air flows
through the cells from the lower side and then pulled
though the fan no. 2.
