after disconnectingt he battery. The vehi-
cle is secured against rolling away. You
can then no longer move the vehicle.
The batter yand the cover of the positive
terminal clamp must be installed securely
during operation.
Comply with safety precaution sand take pro-
tective measures when handling batteries. Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the bat-
