RUpon request of the trade association a test manual is to be maintained into which specific entries are made. 3. Safety instructions3.1 Risk of electric shocks3.1.1 Low voltages, high voltagesHazardous voltages occur in both the lightingsystem and the electrical system of a motorvehicle. If contact is made with live parts (e.g.with the ignition coil), there is a risk of electricshock from flashover voltages caused bydamaged insulation (e.g. ignition cables whichhave been attacked by martens). These apply to the secondary and primary sides of the ignition system, the wiring harness with con-nectors, lighting system (Litronic) as well as connection to the vehicle.Safety measures: ¶Only connect to a properly grounded outlet. ¶Only the enclosed or a tested power supply cable is to be used. ¶All extension cables must be fitted with shock-proof contacts. ¶Any cables with damaged insulation must be repla-ced. ¶First connect the lighting system and turn it on befo-re connecting it to the vehicle. ¶Before switching on the ignition connect the (B-) cable to engine ground or the battery (B–) terminal. ¶Always switch off the ignition before performing any work on the electrical system of the vehicle. Inter-vention includes, for instance, connection to the vehicle, replacement of ignition system components, removal of equipment (e. g. alternators), connection of equipment to a test bench. ¶Wherever possible, tests and settings should always be caried 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 connection cables and leads as well as to connec-tions of equipment to test benches. ¶Test connections must always be made using sui-table connectors (e.g. Bosch testing cable set or vehicle-specific adapter cables). ¶Make sure that all test connections are properly plugged in and secure. ¶Before disconnecting the (B-) cable from the engine ground or battery (B–), switch off the ignition. ¶Never open the enclosures.

Bosch Automotive Diagnostics Equipment (Shenzhen) Limited Safety instructions | VCI | 7VCI | 7 | 7 en3.1.2 High voltages in hybrid vehicles and electric ve-hicles as well as their high-voltage componentsIf high-voltage components or high-voltage wires are inexpertly handled, there is a risk of fatal injury from high voltages and the possib-le transmission of current through the body. ¶Deenergization is only to be performed by a qualified electrician, a qualified electri-cian for specific tasks (hybrid) or a power systems engineer. ¶Work on vehicles with high-voltage compo-nents is only ever to be performed in a safe, deenergized condition by persons with the minimum qualification "Trained to perform electrical work". ¶Even after deactivating the high-voltage vehicle electrical system, the high-voltage battery may still be live. ¶Operating condition cannot be established from any running noise, as the electric ma-chine is silent when stationary. ¶In gear positions "P" and "N" the engine or electric motor may start spontaneously depen-ding on the charge of the high-voltage battery.Safety measures: ¶Never open or damage high-voltage batteries. ¶On accident vehicles, never touch high-voltage com-ponents or exposed high-voltage wires before deacti-vating the high-voltage vehicle electrical system. ¶Avoid contact with any high-voltage components and high-voltage wires (orange sheathing) when in operation. ¶Secure against unauthorized renewed start-up (e.g. by means of a padlock). ¶Always wait at least 10 seconds after deactivating the high-voltage system. ¶Visually inspect the high-voltage components and high-voltage wires for damage. The power systems engineer responsible should always be immediate-ly notified of any irregularities, doubts or defects found. $High-voltage components must never exhibit signs of external damage. $The insulation of the high-voltage wiring must be intact and undamaged. $Watch out for any abnormal deformation of the high-voltage wiring.3.2 Danger of acid burningWhen exhaust gas measurements are taken, the sampling 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.Rules of conduct: ¶Consult a doctor immediately after inhaling! ¶Always wear gloves made of neoprene or PVC when removing residues left after a fire. ¶Neutralize any residues left after a fire with a cal-cium hydroxide solution. This produces non-toxic calcium fluoride, which can be washed away.Acids and alkalis can cause severe burning on unprotected skin. Hydrogen fluoride in combi-nation with moisture (water) forms hydroflu-oric acid. The condensate, which accumulates in the sampling hose and in the condensate container likewise contains acid.Rules of conduct: ¶When replacing the O2 measuring sensor, bear in mind that it contains alkali. ¶When replacing the NO measuring sensor, bear in mind that it contains acid. ¶Rinse any affected parts of the skin immediately in water, then consult a doctor! ¶NO and O2 measuring sensors are hazardous waste and must be disposed of separately. Your Bosch spe-cialist equipper can dispose of sensors in the proper manner.If liquid crystal escapes from a damaged liquid crystal display, it is imperative to avoid direct skin contact, inhalation and swallowing.Rules of conduct: ¶If you have inhaled or swallowed liquid crystal, con-sult a doctor immediately! ¶Wash the skin and clothing thoroughly with soap and water if it has come into contact with liquid crystal.If fluid (electrolyte) escapes from batteries and rechargeable batteries, avoid getting it on your skin or in your eyes.Rules of conduct: ¶If contact with skin or eyes happens nevertheless, wash the affected parts immediately with clean wa-ter and then consult a doctor.

Bosch Automotive Diagnostics Equipment (Shenzhen) Limited 8 | VCI | Safety instructionsen3.3 Danger of injury, Danger of crushingThe vehicle has rotating and moving parts that can injure fingers and arms.If the vehicle is not prevented from rolling away, there is a danger of people being crus-hed against a workbench, for example.There is the risk with electrically operated fans in particular that the fan can start run-ning unexpectedly even when the engine and ignition are off.Safety measures: ¶Take steps to prevent the vehicle from rolling away while it is being tested. Select the park position if the vehicle has an automatic transmission and apply the handbrake or lock the wheels with chocks (wedges). ¶Operating staff must wear work clothes without loose bands and loops. ¶Do not reach in any area with rotating or moving parts. ¶When working on or in the vicinity of electrically driven fans, allow the engine to cool down first, then disconnect the plug of the fan motor. ¶Route cables at a suitable distance from rotating parts. ¶Secure the trolley against rolling away by setting the brakes. ¶Do not place heavy objects on or lean on the sensor holder. ¶Transport and operate the equipment only in ac-cordance with the operating instructions.3.4 Danger of burningWhen working on a hot engine, there is a risk of injury from burning if such components as the exhaust gas manifold, the turbo-charger, the Lambda sensor, etc. are touched or if parts of the body come too close to them. These components may be heated to tempe-ratures of several hundred degrees Celsius. Depending on the duration of the exhaust gas measurements, the sampling probe of the exhaust gas measuring instrument may also become extremely hot.Safety measures:: ¶Always wear protective clothing, e.g. gloves. ¶Allow the engine to cool down first. This also applies to auxiliary heating systems. ¶Keep connecting cables well away from all hot parts. ¶Do not leave the engine running any longer than necessary for the test or setting.

Bosch Automotive Diagnostics Equipment (Shenzhen) Limited Safety instructions | VCI | 9VCI | 9 | 9 en3.5 Danger of fire, Danger of explosionThere is a risk of fire and explosion from fuels and fuel vapors when work is performed on the fuel system or on the mixture control system.Safety measures: ¶Switch off the ignition. ¶Allow the engine to cool down first. ¶Avoid naked flames and potential sources of sparks. ¶Do not smoke. ¶Collect any leaked fuel. ¶Always ensure effective ventilation and suction when working in closed areas.3.6 Danger of asphyxiationCar exhaust fumes contain carbon monoxide (CO) - a colorless, odorless gas. If inhaled, carbon monoxide causes an oxygen deficiency in the body. Extreme caution is therefore es-sential 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 measures: ¶Always ensure effective ventilation and suction (es-pecially when working in a pit). ¶Always switch on and connect the suction plant in a closed area.3.7 NoiseNoise levels in excess of 70 dB(A) can occur when measurements are carried out on a vehicle, especially at high engine speeds. Da-mage to hearing may result if human beings are exposed to noise at such levels over an extended period of time.Safety measures: ¶Noise protection facilities must be provided by the ow-ner at all workplaces in the vicinity of the testing area. ¶Suitable personal noise protection facilities must be used by the operator.3.8 Danger of trippingWhen conducting tests or making adjust-ments, the sensor and connection cables increase the risk of tripping.Safety measures: ¶Route the connecting cables such that any risk of tripping up is prevented.
