CHECKING EMISSIONS AT EXHAUST

Exhaust emission should be checked outdoors or at least in a suitable place according to current regulations.

The engine should be at normal operating temperature (i.e. when the fan has come on and turned off) and at idle speed (see GROUP 00 - "TECHNICAL SPECIFICATIONS OF THE ENGINE"). If idle speed is not within the specified limits check that the constant idle speed actuator is working properly.

• Check that the engine oil level is correct and that the air cleaner cartridge is clean.
• Start the engine and keep it at idle speed.

1. Insert the feeler of the analyser in the end of the exhaust pipe and check that the amount of CO and HC are within the specified limits.
