Extension Cords
If an extension cord is used, the cross sectional
area of its conductors must meet the following
minimum requirements – depending on the line
voltage and length of the extension cord:
If rated voltage on the rating label is 220V to
240V:
– Cord length up to 20 m: AWG 15 / 1.5 mm²
– Cord length 20 m up to 50 m: AWG 13 /

Temperature Limits
WARNING
■ The battery is not protected against all ambi‐
ent conditions. If exposed to certain ambient
conditions, the battery may catch fire or
explode. This may result in serious injury to
people and damage to property.
► Do not charge or use the battery below
-20 °C or above +50 °C.
► Do not store the battery below -20 °C or
above +70 °C.
► Do not use the lawn mower below 0 °C or
above + 50 °C.
► Do not store the lawn mower below - 20 °C
or above + 70 °C.

Recommended Temperature
Ranges
For optimum performance of the lawn mower,
the battery and the charger, observe the follow‐
ing temperature ranges:
– Lawn mower:
– Usage: 0 °C to +40 °C
– Storage: -20 °C to +50 °C
– Battery and charger:
– Charging: +5 °C to +40 °C
– Use: -10 °C to +40 °C
– Storage: -20 °C to +50 °C
If the battery is charged, used or stored outside
the recommended temperature ranges, perform‐
ance may be reduced.
If the battery is wet or damp, allow it to dry for at
least 48 hours at above +15 °C and below
+50 °C and at less than 70% humidity. Higher
humidity may increase the drying time.

Sound Values and Vibration
Values
The K value for the sound pressure level is
3 dB(A). The K value for the sound power level is
2.5 dB(A). The K value for the vibration value is
0.9 m/s².
– Sound pressure level L
ance with EN IEC 62841-4-3: 76 dB(A)
– Guaranteed sound power level L
ured in accordance with 2000/14/
EC / S.I. 2001/1701: 90 dB(A)
– Vibration value a
hv
with EN IEC 62841-4-3, handlebar: 1.80 m/s²
The indicated vibration values were measured in
accordance with a standardised test method and
can be used for the purpose of comparing electri‐
cal appliances. The actual vibration values that
occur may deviate from the indicated values,
depending on the type of application. The indica‐
ted vibration values can be used for an initial
assessment of the vibration load. The actual
vibration load must be assessed. Times during
which the electrical appliance is switched off,
along with times during which it is switched on
but running without load, can also be taken into
consideration.

Vibration Directive 2002/44/EC and
S.I. 2005/1093, see www.stihl.com/vib .
