MAINTENANCE
Attention
should
be
paid
to
the following
points with
a
view
to
obtaining
the
maximum mileage
from
the
road
wheels
and
tyres.
1.
Change
the
positions
of
the
tyres
on
the
car
at
regular
intervals.
2. Test
the
pressures
of
the
tyres
with
an
accurate
pressure
gauge.
Restore
any
air
lost.
In■ate
the
spare
wheel
to
the
rear
wheel
pressure.
It
is
not
suf■cient
to
make
a
visual
examination of
the
tyres
for
correct
in■ation.
3. Keep
the
treads free
of
grit,
■int,
stones,
or
other
foreign
matter,
and
repair
cuts
as
soon
as
they
are
found.
4. Clean
the
wheel
rims and keep
them
free
of
rust.
Repaint
them
when
necessary.
5.
Keep
the
brakes
and
clutch
correctly
adjusted
as
fierceness
or uneven
action
from
either of
these
units
has
a
detrimental
effect
on
tyre
wear.
6.
Suspect
misalignment
if
rapid
wear
of
the
front
tyres
is noticed
and
correct
the
fault
at
once.
See
Section
I
for
details
of
front
wheel
alignment.

7. Remove
oil
or
grease
with
petrol
sparingly
applied
and
wipe
off
immediately.
8.
Avoid
over-
and
under-in■ation,
kerbing,
and
other
causes
of
severe
impact.
9.
Repair
any
damage
immediately
it
is
discovered
and
remove
tyres
before
they
have
worn
too
far
for
remoulding.
Tyre
replacement
Radial-ply
tyres
should
only
be fitted
in
sets
of
four,
although
in
certain
circumstances
it
is
permissible
to
fit
a
pair
on
the
rear
wheels;
tyres
of different
construction
must
not
be
used
on
the
same
axle.
A
pair
must
never
be ■tted
to
the front
wheels
with
conventional
tyres
at
the
rear.
The
positional
changing
of
wheels
must
not
be
undertaken
if
radial-ply
tyres
have
been
to
fitted
the
rear
wheels
only.
Section
0.2
JACKING
UP
THE
CAR
A
jacking
tube
is
■tted
to
each side
of
the
car
under
the
■oor
panel
approximately
midway
along
the
body.
The
jack
will lift
one
side of
the
car
and
thus
enable
a
front
or
rear
wheel
to
be
changed.
Before
jacking
up
the
car
apply
the
hand
brake
and if
the
car
is
standing
on
an
incline
chock
the
wheels.
Place
the
jack
in
the
appropriate jacking
tube
so
that
the
top
of
the
jack
leans
slightly
outwards
to
allow
for
radial
movement
of
the
body
when
the
car
is
lifted.
Remove
the
hub
cover
and slacken
the
wheel
nuts
a
turn
or
two
before
commencing
to
lift
the
car.
Operate
the
jack
until the
road wheels
are
clear
of
the
ground.
After
changing
the
wheel
lower
the
car
and
remove
and
stow
the
jack.
Do
not
use
the
jack
as
a
support
for
the
car
when
carrying
out
servicing
operations underneath
the
car.
