HOW TO USE THIS MANUAL This manual is divided into Level 1 maintenance sections. If doubt exists as to the serviceability or mechanical integrity of the F1A4, turn to Section 2 for a comprehensive mechanical and functional test of the F1A4. If any mechanical component (eg handgrip, coil) of the F1A4 requires replacement, turn to Level 1 maintenance procedures in Section 3, which details all mechanical repairs. -

F1A4 should be on hand. After any repair to the F1A4, Section 2.2 Functional Testing, must be completed in full to ensure the F1A4 is returned for operational use. -
Page 8: Functional Testing
This section details functional testing of the F1A4. It should be used to confirm serviceability of an F1A4 before it is returned to the field for use and whenever doubt exists about the serviceability of an F1A4. The F1A4 must pass all these tests to be considered serviceable. - Page 9 The F1A4 should initially detect the GB Test Piece (a change of threshold tone will be heard) as the GB Test Piece is moved to and from the Coil. The F1A4 will then become “balanced” to it, i.e. the F1A4 threshold will remain stable as the GB Test Piece is moved to and from the Coil.

30 degrees side to side, listening for a change of threshold. If there is a noticeable threshold change (ie similar in volume to test piece threshold change), the Coil should be replaced (Section 3.4) or the F1A4 should be sent to an accredited F1A4 Level 2 maintenance workshop for repair. -
Page 11: Maintenance Procedures
CAMLOCK REPAIR PROCEDURES This procedure details the dismantling and re-assembly of the Camlocks fitted to the Upper Shaft of the F1A4. This is only necessary when a Camlock becomes damaged or worn. The F1A4 uses Camlocks in three locations – Upper Camlock locks the armrest into the Upper shaft, Lower Camlock locks the lower shaft into the Upper shaft and the Handle camlock locks the Handle onto the Upper shaft. - Page 12 F1A4 Field Service Manual – Level 1 Maintenance 3.1.1 Servicing the Upper and Lower Camlocks Knock out Camlock Pivot Pin with the 3 to 3.5mm punch.
