 Repairing the headpiece
Only the small insulated screwdriver (P/N 201042)
should be used as this allows the screws to be
secured tightly without fear of a short-circuit or
other damage.
1. The switch should be placed in the off position
and the battery fuse removed (see section cap
lamp system) before disassembly of the
headpiece. When reassembling the headpiece,
ensure that the sealing channel is correctly
fitted around the reflector.
2. The reflector is located by two projections which
fit either side of the pin that rests against the
envelope of the pilot bulb.
3. The bezel ring should be screwed down firmly
while holding the glass firmly down with your
thumb.
4. The lock pin placed so that it fits into one of the
recesses of the bezel ring and firmly screwed
tight. The lock screw can be sealed with wax –
if applicable.
WARNING
It is essential that all contacts in the headpiece
are tight, so that no electrical resistance is
incurred which might increase the time
necessary to obtain an efficient charge or
possibly reduce the light output of the lamp.
In order to obtain the maximum light possible,
the outside of the lens glass should be cleaned
thoroughly.
