Atomisers

Atomiser faults Operation 11-4
There are two types of atomisers used on the 900 Series engine. Early engines use a clamp to retain each
atomiser. Later engines use atomisers where the body of the atomiser is held in position with a gland nut.
Warnings!
l If your skin comes into contact with high-pressure fuel, obtain medical assistance immediately.
l Keep away from moving parts during engine operation. Some moving parts cannot be seen clearly while
the engine runs.
In order to find which atomiser is defective, operate the engine at a fast idle speed. Loosen and tighten the
union nut (A1) of the high-pressure fuel pipe at each atomiser. Do not loosen the union nut more than half a
turn. When the union nut of the defective atomiser is loosened, it has little or no effect on the engine speed.
