to the hea dlamp body and detach the rim together with diffuser a nd
reflector from the headl a mp body. Then press out the bulb hold er s,
remove
the connecting block from the double-filament bulb of the
high and lower beams and fit a new one following the procedur e re -
ve r se to th at described above.
In
order to replace the parking light bulb take out the socket with
the bulb and take out the bul,b from the socket.
When rep lacing a burn t-Gut bulib in the pilot lamps (tl1LI.20E and
DLI.29Ll.), take the lamp o ut of the pan el and detach the bulb from
the socket.
When replacing a broken diffuser or repairing the h ea dl amp, it
is necessary to clean the reflector by blowi ng it round and caref ully
wiping with a clean flannel cloth or soft brush. The diffuser with the
reflector may be disassembled o nly in exceptional cases, since fre-
quently performed disma ntling may cause damage to the reflector.
When assembling the diffuser take care to ensure its co rr ect in stal -
l
atio n.
• In case the sou nd of the horn deteriorat es, the latter should be
a djusted by turning the adjusting . sc re w in one di ·rection or the ot her.
Ever y 1000 km, it is necessary to check:
the condition of the working surface of the co ntact bre ake r points
and the gap be twee n them (if the bre aker contacts (poin ts ) are worn
or burnt, remove the movi ng contact and fixed contact, cle an the con-
tacts with a ne edle file a nd wash them with petrol).
Every 5000 km run check the following:
the
spark g ap of the plug s (the gap should be equal to 0.5-
0.6 mm); if req uir e d, cl ean the p. lugs to remove the ca rbon d.eposit;
the wi res f or rel ia ible co nne ction ;
the bul bs in the lamps for proper fitting and working condition;
if
necessary, clean off dust f·rom the headlamp reflector and wipe the
glass of the lamps.
Wipe the storag-e b attery to re move dust and dirt, clean out the
ho l es in the p lu gs, clean o ff oxides from the b attery termina ls and
coat the latter with tec hni cal petroleum jel ly, check the level of ele-
ctro lyte and verify the electr. olyte density with a battery densimeter.
In summ er, when irt is hot, check the electrolyte density eve ry 5
to 6 days,
during other seasons , eve ry 10 to 15 days. The level of the
electrol yte in the battery mu st be 10 to 12 mm above the protective
shie l'd. If the 'level of the el ectro ly te is be low the s·pecified limits, add
distilled wate r (water evapo r ates during usage of the b attery). Ele-
ctrolyte is to be ad ded only wh<!n it is exactly known that it has
been spilt.
Checking of the electrol yte density makes it possible to determi-
ne the state of charge of the battery and, consequently, its working
condition. Particular atte ntion sho uld be give n to the electrolyte den-
sity in winter. A d ischarged battery may get f·rozen. Th e storage
b at tery may be utilized when discharged by not m ore tha n 25 per
cent in winter time, and by not more than 50 per cent in summer
time.
