WARNING!
Danger of explosion!
In general, the negative pole (-) of the car battery is connected
with the chassis. But there are also exceptions. When connect-
ing the battery terminal clamps, reversing the poles may result
in a short-circuit, sparks and an explosion.
− Check which of the battery poles (+ or -) in the vehicle is
directly connected to the chassis. This determines the or-
der for safely attaching the battery terminal clamps.
1. Check which battery pole (+ or -) is not directly connected to the chassis. If
this concerns
• the positive pole (+) of the battery, connect the red battery terminal
clamp (+)
• the negative pole (-) of the battery, connect the black battery terminal
clamp (-)
2. To connect to the vehicle chassis, connect the free battery terminal clamp
to a screw or bare metal as far away from the battery and the petrol line as
possible.
