Instructions for your personal safety and for the
protection of equipment/vehicle components
Mains voltages
High voltage
Hazardous voltages occur in both the lighting
system and the electrical system of a motor
vehicle. If contact is made with live parts (e.g.
with the ignition coil), there is a risk of electric
shock from flashover voltages caused by da-
maged insulation (e.g. ignition cables which
have been attacked by martens). This applies
to both the primary side and the secondary
side of the ignition system, to the cable har-
ness and the plug connections, to the lighting
systems (Litronic) and to the tester connec-
tions.
Safety precautions:
- Any cables with damaged insulation must
be replaced (e.g. power or ignition cables).
- Connect testers to the engine ground or to
the battery (B-) before switching on the
ignition.
- Always switch off the ignition before perfor-
ming any work on the electrical system of
the vehicle. The term „work" includes con-
necting testers, replacing parts of the igni-
tion system, removing assemblies (e.g. ge-
nerators), connecting assemblies to a test
bench, etc.
- Wherever possible, tests and settings
should always be carried out with the igniti-
on switched off and the engine stationary.
- If tests or settings are carried out with the
ignition switched on or the engine running,
care must be taken not to touch any live
parts. This applies to all the connecting
cables of the testers as well as to the
connections of any assemblies at the test
bench.

- Test connections must always be made
using suitable connectors (e.g. Set of Test
Cables 1 687 011 208 or vehicle-specific
adapter cables).
- Make sure that all test connections are pro-
perly plugged in and secure.
Danger of asphyxiation
Car exhaust fumes contain carbon monoxide
(CO) - a colorless, odorless gas. If inhaled,
carbon monoxide causes an oxygen deficien-
cy in the body. Extreme caution is therefore
essential when working in a pit, as some of the
components of the exhaust gas are heavier
than air and settle at the bottom of the pit.
Caution is also necessary when working on
LPG-driven vehicles.
Safety precautions:
- Always ensure effective ventilation and
suction (especially when working in a pit).
- Always switch on and connect the suction
plant in a closed area.
