Operate the charger only indoors, in dry rooms and within an
ambient temperature range of 41 °F to 104 °F (5 °C to
40 °C).
The battery heats up during operation of the power tool. If a

for it to cool down before charging starts. The charging
process begins only after the battery has cooled down
sufficiently.
Charging time depends on a number of factors, including
battery condition and the ambient temperature. For a
complete list of approximate charging times, see
