6.1.2.3 The adhesive recommended for usage is acrylate cyanide,
type LOCTITE 454, or the like providing an adequate bonding of
fiberglass laminate with polyvinyl chloride (the adhesive sets in 2 to 3 min
and the unit may be used after a lapse of 24 h). For the bonding
procedure, refer to the Instructions for Cement Usage.
6.1.2.4 While bonding the fastener press its smooth side to the
helmet surface evenly without applying an excessive force. Apply
pressure to the fastener total area and use a screw clamp for locking the
parts to be bonded (Uniformly press the sticking fastener against the
helmet until its strip is bonded to the helmet, use should be made of the
suitable device).
6.2 Individual Adjustment and Fitting (Figs 6.4 thru 6.6)
CAUTION: EACH PILOT SHOULD CARRY OUT INDIVIDUAL
FITTING AND ADJUSTMENT OF THE NIGHT-VISION GOGGLES.
Before starting the adjustment check to see that the lenses are
closed with safety caps.
6.2.1 Remove the night-vision goggles from the case.
6.2.2 Depress button (1) (Ref. Fig. 6.4) and, while holding the fixing
assembly in one hand, take monoculars (28) and (29) in the other hand,
transfer the goggles to the operating position so that the fixing assembly
is straightened. In doing so, see that only a slight force is applied to
securely lock (latch) the monocular pair in the operating position,
indicated by a click of retainer (21) (Ref. Fig. 5.2).
CAUTION: IN THE EVENT OF FAILURE OF THE RETAINER TO
LATCH THE MONOCULAR PAIR IN THE OPERATING POSITION, THE
NIGHT-VISION GOGGLES WILL NOT BE ENERGIZED AND THE
INDIVIDUAL ADJUSTMENT WILL NOT BE POSSIBLE.
6.2.3 To ensure proper latching, essential for retaining the
monocular pair in the operating position, check to see that the hinged joint
linking the monocular pair to the unit fixing assembly is reliably locked.
