TEST SEQUENCE
NOTE
These adjustment procedures assume prior knowledge of some aspects of
disassembly of the 318. If further information is required, refer to the disassembly
procedures in Section 6:General Maintenance.
It is necessary to perform the following sequence step by step, because all timings in the 318 are level-sensitive.
