TDB 1, TDB 6
and
TDB 3
end pieces of the
DBG-F2
device, with moving arm, have been designed
for adaptation to the different operating conditions on rails and track fittings; their assembly is
shown in Fig. 13.
• When assembling the TDB 3 end piece ensure that the positioning pawl is pointing down-
ward in relation to the bolt.
• When disassembling the TDB 6 end piece ensure that, after removing the pivot, the com-
plete assembly is slid away downwards without acting on the holding plate.
• Over-advancing the spindle after drilling must be avoided when using the TDB 1 and TDB3
end pieces.
