Ambient Temperature Recom‐
mendations
For optimum performance, observe the following
ambient temperature ranges for the trimmer, bat‐
tery and charger:
– Charging: 41 °F to 104 °F (5 °C to 40 °C)
– Use: 14 °F to 104 °F (- 10 °C to 40 °C)
– Storage: - 4 °F to 122 °F (- 20 °C to 50 °C)
Charging, using or storing the battery outside the
recommended ambient temperature ranges may
reduce performance.
If the battery became damp or wet during opera‐
tion, allow it to dry at least 48 hours at tempera‐
tures between 59 °F (15 °C) and 122 °F (50 °C)
and relative humidity below 70 % before charg‐
ing or storing. Higher humidity can extend the
drying time.
