Technician Safety Information

AA. Ignition and high tension components







Switch ignition off before:
- Connecting and disconnecting test instruments
- Connecting and disconnecting connectors.
- Taking readings with an ohmmeter.







High tension
Dangerous voltages are present at all points in the system, including connectors etc.


WARNING! THE IGNITION SYSTEM OPERATES AT HIGH POWER AND VOLTAGES. IT IS DANGEROUS TO COME IN CONTACT WITH THE HIGH TENSION CIRCUIT - THE IGNITION COIL, SPARK PLUG CAPS AND DISTRIBUTOR CAP.


CAUTION! Avoid sparking when working on the fuel system, especially when working on injectors.







AB. Battery
When testing components it is important that battery voltage is normal (approx. 12 V). If necessary, a battery charger can be connected during testing.

Connect battery charger to the battery terminals. Charge battery for approx. 10 hours at the recommended current - maximum 6 A.

Example: If the battery is marked 520 A a charge current of 0.01 x 520 = 5.2 A is recommended.

A higher than recommended charge current can damage the battery.


NOTE: Boost charging (with a high current or voltage above 16 V) will damage the battery and is prohibited.


WARNING! WHILE THE BATTERY IS BEING CHARGED AN EXPLOSIVE MIXTURE OF OXYGEN AND HYDROGEN GASES IS FORMED. SMOKING, WELDING, GRINDING OR OTHER ACTIVITIES INVOLVING SPARKS OR NAKED FLAMES ARE PROHIBITED IN THE VICINITY OF A CHARGING BATTERY. BATTERIES MUST BE CHARGED IN A WELL VENTILATED AREA.

AC. Safety instructions when handling refrigerant







AC1
Always wear tight-fitting safety glasses if there is any risk for refrigerant leakage.

If you get refrigerant gets in the eyes rinse immediately in running water for 15 seconds. Seek medical assistance if you experience any problems after exposure (with vision etc).

Protect exposed skin (hands) to avoid frostbite injuries. If skin is exposed to refrigerant, flush affected area with warm running water. Treat injury as for frostbite.







AC2
Toxic gases may be generated if refrigerant comes into contact with an naked flame.


WARNING! TOXIC GASES GENERATED WHEN REFRIGERANT IS HEATED ARE HAZARDOUS TO HEALTH. THESE GASES HAVE AN IRRITATING PRICKLY SMELL AND CAN CAUSE LUNG DAMAGE. THE SYMPTOMS CAN CONTINUE FOR A LONG TIME AFTER YOU HAVE BEEN IN CONTACT WITH THE GASES. THE GASES CAN CAUSE LUNG DAMAGE EVEN IF THE AMOUNT OF GAS IN THE AIR IS TOO LITTLE TO SMELL IT.


Do not keep gas bottles where the temperature can exceed 45 °C (113 °F).


WARNING! EXPOSING A GAS BOTTLE TO HEAT WILL CAUSE THE PRESSURE IN THE BOTTLE TO INCREASE WITH A CORRESPONDINGLY GREATER RISK OF AN EXPLOSION OCCURRING.


NOTE: Some countries have special legislation about working with air-conditioning Systems.
Only qualified technicians are to be allowed to work with the A/C system!
