Page 4: Exhaust Gas
Safety precautions I Exhaust gas If you come into contact with any of these fl uids, consult a doctor immediately. Exhaust gases contain carbon monoxide. This colourless If the engine gets too hot, switch it off and disconnect it and and odourless gas is extremely harmful and could lead to wait for it to cool down before handling. - Page 5 Safety precautions I Accidental starting Do not wear bracelets, necklaces or rings when working on the engine. Accidental starting can cause serious injury and even death! Check that the bolts and screws are properly tightened and Disconnect the battery before working on the engine. that the protection mechanisms are in place.
