3.11 Start with jump leads
Preparation
■
Observe precaution measures for handling batteries (see Safety
instructions).
■
Pay attention to the nominal voltage of the batteries.
■
A discharged battery can freeze already at 0 °C (32 °F). It is essential
that you defrost a frozen battery in a warm room before connecting it
with jump leads.
■
Use jump leads with an insulated terminal clamp and a cross section
of at least 25 mm².
■
The terminal clamps of one lead may not come in contact with those
of the other.
■
Do not disconnect the battery from the vehicle's supply system.
■
Charging vehicle and discharged vehicle may not come in contact
with each other.
Connecting leads
1. Connect one terminal clamp of one wire with the positive terminal of
the charged battery (plus sign).
2. Connect the other terminal clamp of this lead to the positive terminal
of the discharged battery (plus sign).
3. Connect one terminal clamp of the second wire with the negative
terminal of the charged battery (minus sign).
4. Connect the other terminal clamp of the second wire with the
discharged vehicle e.g. at the engine block or at the fastening screw
of the engine suspension. Do not connect the terminal clamp with the
negative terminal of the discharged battery (risk of explosion) but as
far away from the discharged battery as possible.
5. Lay leads such that they are not drawn into rotating parts and that
they can be taken off even with a running diesel engine.
Starting process 1. Start the engine of the charging vehicle and let it run with medium
engine speed.
2. Start the diesel engine of the discharged vehicle after approx. 5 min.
3. For approx. 3 min let both engines run with medium engine speed
and the jump leads connected.
