MAINTENANCE ON VAPORISOR
Maintenance on the vaporisor should include the checking of the secondary valve actuating lever (1).
The Impco maintenance kits are used for two different vaporisor types (series E and EP). As a result, a
check must be carried out, and, if necessary, the actuating lever (1) has to be bent accordingly.
To carry out the check and the bending adjustment, proceed as follows:
After assembly of the maintenance kit, check the position of the connecting pin (4) using a setting bar (3)
and a feeler gauge. A setting bar is placed over the housing (5). The spring (2) pushes the valve into its
closed position. The distance between the connecting pin (4) and the setting bar (3) must be 1 mm. If
necessary, the actuating lever (1) should be bent to achieve this dimension.
