INSTRUCTIONS FOR USE

LEAD DETECTION AT THE EXHAUST

1. - Test conditions:

• Engine off.
• Exhaust pipes warm but not hot.
• Do not perform the test at a temperature below 0 °C.

1. 1
   - If necessary, gently clean the inside of the exhaust outlet with a dry cloth to remove soot deposits.
2. 2
   - Put on gloves, take a test paper and dampen it lightly with distilled water (if too wet, the paper loses its effectiveness).
3. 3
   - Immediately after dampening, press the test paper onto the cleaned part of the exhaust and hold firm pressure for about one minute.
4. 4
   - Remove the test paper and let it dry. The presence of lead is indicated by a red or pink colour on the test paper.

CAUTION: the lead test must be carried out on the rear exhaust outlet, never on the oxygen sensor.
