4.5  Battery 

 
Each Weasel is powered by a maintenance-free battery. Only use 
the  designated  batteries  supplied  with  your  Weasels.  The  daily 
runtime of the battery, as well as its lifetime, strongly depends on 
the individual use and battery age. You can expect about 8 hours 
of driving time and about 8 hours of charging time.  Make sure to 
replace  and  recharge  the  batteries  soon  enough.  Exhaustive 
discharging may damage your battery, it may lose capacity or fail 
completely.  
 
There are two batteries provided for each Weasel. This means that a Weasel can also be used in multi-
shift operation without any problems (one battery is operating in the vehicle while the other one is being 
charged). If you use a Weasel in one-shift operation only and one charge is sufficient, you can use the 
batteries alternately in order to increase their life.  
 
Always turn your Weasel off when removing/replacing the battery. Loosen the front latch of the structure 
and push it towards the front. Press the side holder back and lift the battery up by the handle. 

4.6  Charger 

 
The  charger  is  a  simple  device  for  recharging  your  Weasel 
batteries.  To  charge  a  battery,  power  the  charger  via  the  mains 
connector and insert the battery. The LED display of the charger 
will indicate the current state: 
 

  Green (flashing): No battery inserted 

  Yellow (continuous light): Charging in process  

  Yellow (flashing): Final charging phase  

  Green (continuous light): Charging complete 

Make sure the battery is fully charged before installing it in your Weasel. The chargers may only be 
used for charging the designated batteries. They must not be used for storing any other materials.  

4.7  LEDs 

 

The LEDs of your Weasel indicate its state. Normally, the LEDs will flash at a frequency of 1 Hz (Weasel 
without  destination)  or  will  have  continuous  light  (Weasel  with  destination).  When  a  Weasel  turns 
left/right, only one of the two LEDs will be on to indicate the current direction. Using special LED signals, 
the Weasel signals that an error has occurred.  
 

Fault signal

 

 

Meaning 

Flashing quickly (3 Hz) 

Weasel has lost track and is stopped for this reason. Lift up the 
front carefully to position the pivoted drive unit with the camera 
in the middle of the track. If necessary, clean and repair the 
track. Once the Weasel sees the track again, it will move on.
