f Warning! Switch off, remove the isolator key,
battery and grassbox before adjusting or clean-
ing.
f Always wear gardening gloves when handling or
working near the sharp blades.
Use the following procedures to enable optimum us-
age of the battery:
– Protect the battery against moisture and water.
– Store the battery only within a temperature range
between 0 °C and 50 °C. As an example, do not
leave the battery in the car in summer.
– Do not leave the battery in the product in direct
sunlight.
– The ideal storage condition for the battery is 5 °C.
– Occasionally clean the venting slots of the battery
using a soft, clean and dry brush.
A significantly reduced working period after charging
indicates that the battery is used and must be re-
placed.
