INFORMATION ACCESSORIES AND CONVERSIONS
DO NOT FITunapproved accessories or conversions,
as they could affect the safety of the vehicle.
Land Rover will not accept liability for death, personal
injury, or damage to property which may occur as a
direct result of the fitting of non-approved conversions
to the vehicle.
WHEELS AND TYRES
WARNING: DO NOT replace the road
wheels with any type other than genuine
Land Rover wheels which are designed for
multi-purpose on and off road use and have very
important relationships with the proper operation
of the suspension system and vehicle handling.
Replacement tyres must be of the make and sizes
recommended for the vehicle, and all tyres must
be the same make, ply rating and tread pattern.
STEAM CLEANING
To prevent consequential rusting, any steam cleaning
within the engine bayMUSTbe followed by careful
re-waxing of the metallic components affected.
Particular attention must be given to the steering
column, engine water pipes, hose clips and ignition
coil clamp.
SPECIFICATION
The specification details and instructions set out in
this Manual apply only to a range of vehicles and not
to any one. For the specification of a particular vehicle
purchasers should consult their Dealer
The Manufacturer reserve the right to vary their
specifications with or without notice, and at such times
and in such manner as they think fit. Major as well as
minor changes may be involved in accordance with
the Manufacturer's policy of constant product
improvement.
Whilst every effort is made to ensure the accuracy of
the particulars contained in this Manual, neither the
Manufacturer or Dealer, by whom this Manual is
supplied, shall in any circumstances be held liable for
any inaccuracy or the consequences thereof.SPECIAL SERVICE TOOLS
The use of approved special service tools is
important. They are essential if service operations are
to be carried out efficiently, and safely. Where special
tools are specified,only these tools should be used
to avoid the possibility of personal injury or
damage to the components.Also the amount of time
which they save can be considerable.
Every special tool is designed with the close
co-operation of Land Rover, and no tool is put into
production which has not been tested and approved
by us. New tools are only introduced where an
operation cannot be satisfactorily carried out using
existing tools or standard equipment. The user is
therefore assured that the tool is necessary and that it
will perform accurately, efficiently and safely.
Special tools bulletins will be issued periodically giving
details of new tools as they are introduced.
All orders and enquiries from the United Kingdom
should be sent direct to V. L. Churchill. Overseas
orders should be placed with the local V. L. Churchill
distributor, where one exists. Countries where there is
no distributor may order direct from:
V. L. Churchill Limited,
PO Box 3,
Daventry, Northants,
England, NN11 4NF.
The tools recommended in this Workshop Manual are
listed in a multi-language illustrated catalogue,
obtainable from:
Messers. V. L. Churchill at the above address,
