OPERATING INSTRUCTIONS Repair work Connecting the jumper cables Ü Connect the red jumper cable to the positive pole of the empty battery (1,Fig. 4-1:), then to the positive pole of the charged battery (2). Ü Connect the black jumper cable first to the negative pole of the charged battery (3), then to the negative pole of the empty battery (4). Explosion hazard When the negative terminal is connected to ground, a strong current flows through the jumper cable. The sparks produced in the contact area can ignite the gases emanating from the discharged battery. The negative terminal must therefore be connected to ground at a place as far away from the discarged batteríes as possible.
