Check the state of charge of the battery
The state of charge of the battery should be checked after every 10 000 km
(6 000 miles). The check is carried out with the help of a hydrometer, this show-
ing the specific gravity of the electrolyte which varies with the state of charge.
See page 55. When checking the battery, check also the terminals and terminal
bolts to make sure they are well tightened and smeared with grease or vaseline.
If necessary, wipe off the terminals and terminal bolts with a rag or brush them
with a wire brush before greasing them.

Check headlight alignment
The alignment of the headlights should be checked in a Volvo workshop after
every 10 000 km (6 000 miles). Remember that the section of the road lit up by
the headlights can vary depending on the load in the vehicle.
Replacement of bulbs
To obtain maximum lighting effect and to forestall the chances of lights going
out, the headlights bulbs should be changed every year, suitably during the
autumn. Some of the bulbs have two functions, for example, the headlight
bulbs which have filaments for both mainbeam and dipped lights. The guide pins
on the sockets of these bulbs arc either of different thickness or they are stagger-
ed so that the bulbs can only be fitted in one definite position. Certain makes of
bulbs have a "Top" mark on the socket and this should face upwards.
Replacing the roof light bulb
When replacing the roof light bulb, the
l
amp shade is pulled straight out.
[[When fitting headlight bulbs do not touch the glass
with your fingers. The reason for this is that grease,
oil or any other impurities can be carbonized onto
the bulb and this may damage the deflector.
Replacing the headlight bulbs
Loosen the three screws retaining the rim
with a screwdriver.
Pull out the bottom part of the rim slightly
and then lift upwards so that the retainer
catch releases its grip. (Do not pull out the
headlight rim so far forwards that the catch
at the top becomes bent, otherwise water
can penetrate into and damage the reflector.)
It is not necessary to remove these screws
completely. The insert can be removed by
turning it in an anti-clockwise direction.
Remove the bulb holder contact and take off
the rubber sleeve. Remove the spring fixing
the lamp holder in the correct position.
The bulb and holder are changed complete-
l
y as one unit. When fitting the bulb holder
i
nto the insert, make sure that the small
spring retainer engages in the notch.
