Insert a round object in the hole for the glow plug and press downwards so that the combustion unit is lifted up.

NOTE: Take care not to damage the edge/thread and the nozzle unit. A damaged nozzle unit can result in imbalance (combustion noise) and disruption of function. To avoid this it is important that an object with as large a diameter as possible is used. Do not insert the object too far.
