INSTRUCTIONS FOR USE
PREPARATION OF THE BATTERY
Refer to the vehicle manufacturer
’s handbook for battery maintenance and charging guidelines.
CONNECTION
Check the battery voltage and using the voltage selection switch select the correct output from the
charger; 6v or 12v for MP7108, 12v or 24v for MP7112
Always disconnect the mains supply before making or breaking battery connections. Connect the
battery clips to the battery in the following order:
1.
Connect the positive charging lead (RED) to the positive post of the battery (, +ve or P).
2.
For vehicles with the battery still installed: connect the negative charging lead (BLACK) to the
vehicle chassis (marked -, -ve or N), well away from the battery, fuel line, hot or moving parts.
For batteries removed from the vehicle: Connect the negative charging lead (BLACK) to the negative
post of the battery (marked -, -ve or N).
After connecting the clips, rotate them slightly so as to remove any dirt or oxidization, thus ensuring
a good contact.
