Procedure Numbering
The workshop manual procedures
are
numbered using
the
parts list numbers
as a key. The
first
two
digits
oi a
workshop manual procedure number
are
also
the
parts list number
(e.g.
1.5.01
Sump Removal relates
to PL 1.5 Oil
Pump
and
Sump). Thus when carrying
out a
procedure,
you can
quickly locate
the
relevant parts illustration
and
spare parts list.
To avoid excessive repetition, each procedure will
be
fully detailed once
in its
appropriate place
in the
manual.
In
any other location where this procedure
is
required,
it
will
be
referenced only
by its
title
and its
procedure number.
Special Tools
Where special service tools
are
required
to
perform
an
operation,
the
tool number
is
recorded
at the
point
of use
within
the
procedure.
An
index
and
illustrated list
is
provided
in
this section
for the
purpose
of
identifying special
tools.
References
References
to the
left, right, front
or
rear
of
the vehicle
or of
a component
are
always made as
if
sitting
in the
drivers
seat facing forward.
Any
such references
to
assemblies removed from
the
vehicle
are to the
normal orientation
of
the assembly when fitted
in the
vehicle.
Repairs
and
Replacements
Where replacement parts
are
required,
it is
essential that only genuine Aston Martin parts
are
used. Your attention
is drawn
to the
following points concerning repairs
and the
fitting
of
genuine Aston Martin parts
and
accessories:
• Safety features embodied
in the
vehicle
may be
impaired
if
other than genuine Aston Martin parts
are
fitted.
In certain territories, legislation prohibits
the
fitting
of
parts which
are not
produced
to the
manufacturers
specification.
• Adhere
to
torque wrench settings given
in
this manual.
• Locking devices, where specified, must
be
fitted.
If the
efficiency
of a
locking device
is
impaired during
removal,
it
must
be
renewed.
•
The
vehicle warranty
may be
invalidated
by the
fitting
of
other than genuine Aston Martin parts.
