Overloading security
The overloading security protects the battery against excessive loading. The battery
charger switches off automatically when the battery has been charged completely
in order to protect the battery against overloading.
Deep de-charging protection
The battery is secured against too deep de-charging. This prevents the battery from
de-charging further when a too low battery tension is reached.
Overheating protection
The battery has a built-in temperature sensor that stops the charging when the
battery overheats. The temperature sensor protects the battery when the device is
being used. Otherwise the battery could reach a dangerously high level in case of
overloading or long-term use. In case of overheating the battery must first cool off
before it can be used again. Depending on the ambient temperature and how the
device is being used, it can take up to 30 minutes before the battery has cooled off
sufficiently.
Overvoltage security
The battery is temporarily switched off to prevent damage if the maximum voltage
is exceeded. The normal battery function is reset automatically some seconds after
this security has been activated.
Short-circuiting security
The short-circuiting security switches off and immediately interrupts the circuit of
the battery when the battery short-circuits. This prevents damage to the battery
and/or the device.
Other risks
Even if the device is being used according to the instructions then it is still
impossible to exclude all risk factors. The following potential risks are related to the
design and the functionality of the device:
- damage to the lungs if a dust mask is not being used;
- hearing loss if no hearing protection is being used;
- eye damage is safety goggles are not being used;
- vibration damage if the device is being used too long or is not being maintained
properly.
Vibrations
- Specified vibration values were measured according to a standard test method
and can be used for comparison between devices.
- The specified values can also be used for a provisional assessment of the
exposure.
- Vibration levels may deviate from the specified value, depending on how the
device is being used.
