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 damaged 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 harness and the plug connections, to
the lighting systems (Litronic) and to the tester connections.
Safety precautions:
- All testers must be connected to properly grounded, shock-
proof sockets.
- Testers must always be connected using the power cables
supplied with them.
- All extension cables must be fitted with shock-proof contacts.
- Any cables with damaged insulation must be replaced (e.g.
power or ignition cables).
- Connect testers to the lighting system and switch them on
before connecting them to the vehicle.
- Connect testers to the engine ground or to the battery (B-)
before switching on the ignition.
- Always switch off the ignition before performing any work on
the electrical system of the vehicle. The term "work" includes
connecting testers, replacing parts of the ignition system,
removing assemblies (e.g. generators), connecting assemblies
to a test bench, etc.
- Wherever possible, tests and settings should always be carried
out with the ignition 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 connec-
tors (e.g. Set of Test Cables 1 687 011 208 or vehicle-specific
adapter cables).
- Make sure that all test connections are properly plugged in and
secure.
- Never open the casing of the screen.

Danger of acid burning
in the respiratory system
When exhaust gas measurements are taken, the sam-
pling hoses which are used release a highly caustic gas
(hydrogen fluoride) that can cause acid burning in the respiratory
system when heated to temperatures in excess of 250 °C (482
°F) or in the event of fire.
Safety precautions:
- Consult a doctor immediately after inhaling!
- Always wear gloves made of neoprene or PVC
when removing combustion residues.
- Neutralize any residues left after a fire with a calcium hydroxide
solution. This produces non-toxic calcium fluoride, which can
be washed away.
Danger of acid burning
Acids and alkalis can cause severe burning on unprotected
skin. Hydrogen fluoride forms hydrofluoric acid in combination
with moisture (water).
The condensate which accumulates in the sampling hose and
in the condensate container likewise contains acid.
When replacing the O sensor, it should be remembered that it

contains alkali.
Safety precautions:
- Rinse any affected parts of the skin immediately in water, then
consult a doctor!
- The O sensor is a hazardous waste and must be disposed

accordingly. Bosch technical equipment suppliers are able to
dispose of the sensors O

If liquid crystal escapes from a damaged liquid crystal display,
it is imperative to avoid direct contact between the liquid and the
skin, as well as inhalation or swallowing!
Safety precautions:
- Wash the skin and clothing thoroughly with soap and water if
it comes into contact with liquid crystal.
- Consult a doctor immediately after inhaling or swallowing liquid
crystal.
