OF OF BALL JOINTS AND DUST COVERS
Ball joints are lubricated for their normal life during
manufacture and require no further lubrication. This
applies ONLY if rubber boot has not been dislodged
or damaged. Joints should be checked at specified
mileage intervals but more frequently if vehicle is used
under arduous conditions.
1.Check for wear in joints by moving ball joint up
and down vigorously. If free movement is
apparent fit a new joint assembly.

FAULT DIAGNOSIS STEERING LINKAGE INSPECT
NOTE: When inspecting steering linkages
and ball joints for wear the following items
must be checked.
Steering ball joints
1.Check ball joint rubber boots for security, signs
of cracking or deterioration.
2.Check ball joint assemblies for seizure i.e. no
movement on ball joint and associated
assemblies.
3.Check for excessive wear. This will be evident
as extreme movement on track rod and steering
linkages. Renew parts as necessary.
See
Repair, Track Rod and Linkage See Repair,
Drag Link and Drag Link Ends
Steering linkages
4.Check all linkages for wear, deterioration and
damage. Renew parts as necessary.

DESCRIPTION AND OPERATION AIRBAG STORAGE
Temporary storage
For temporary storage of the airbag module during
service, observe the following precautions:
Store the airbag module with the pad surface up.
Place the airbag module in designated storage area.
If no designated storage area is available, the module
may be stored in the boot of the vehicle from which it
was removed. Always lock the boot when module is
stored in it and inform workshop supervisor.
WARNING: If the airbag is improperly
stored face down, accidental deployment
could propel the unit with enough force to
cause serious injury.
Store the removed airbag module on a secure flat
surface away from heat, oil, grease, detergent or
water.
CAUTION: Improper handling or storage
can internally damage the airbag module,
making it inoperative. If you suspect the
airbag module has been damaged, install a new
unit.
Overnight storage
Airbag modules are classed as an explosive article
and as such they must be stored in a secure steel
cabinet which has been approved by the local
authority.

AIR CONDITIONING
1
ADJUSTMENT GENERAL PRECAUTIONS
The refrigerant used in the air conditioning system is
HFC (Hydrofluorocarbon) R134a.
WARNING: R134a is a hazardous liquid
and when handled incorrectly can cause
serious injury. Suitable protective clothing
must be worn when carrying out servicing
operations on the air conditioning system.
WARNING: R134a is odourless and
colourless. Do not handle or discharge in
an enclosed area, or in any area where the
vapour or liquid can come in contact with naked
flame or hot metal. R134a is not flammable but
can form a highly toxic gas.
WARNING: Do not smoke or weld in areas
where R134a is in use. Inhalation of
concentrations of the vapour can cause
dizziness, disorientation. uncoordination,
narcosis, nausea or vomiting.
WARNING: Do not allow fluids other than
R134a or compressor lubricant to enter the
air conditioning system. Spontaneous
combustion may occur.
WARNING: R134a splashed on any part of
the body will cause immediate freezing of
that area. Also refrigerant cylinders and
replenishment trolleys when discharging will
freeze skin to them if contact is made.
WARNING: The refrigerant used in an air
conditioning system must be reclaimed in
accordance with the recommendations
given with a Refrigerant Recovery Recycling
Recharging Station.
NOTE: Suitable protective clothing
comprises: Wrap around safety glasses or
helmet, heatproof gloves, rubber apron or
waterproof overalls and rubber boots.REMEDIAL ACTIONS
1.If liquid R134a strikes the eye, do not rub it.
Gently run large quantities of eyewash over the
eye to raise the temperature. If eyewash is not
available cool, clean water may be used. Cover
eye with clean pad and seek immediate medical
attention.
2.If liquid R134a is splashed on the skin run large
quantities of water over the area as soon as
possible to raise the temperature. Carry out the
same actions if skin comes into contact with
discharging cylinders. Wrap affected parts in
blankets or similar material and seek immediate
medical attention.
3.If suspected of being overcome by inhalation of
R134a vapour seek fresh air. If unconscious
remove to fresh air. Apply artificial respiration
and/or oxygen and seek immediate medical
attention.
NOTE: Due to its low evaporating
temperature of -30°C, R134a should be
handled with care.
WARNING: Do not allow a refrigerant
container to be heated by a direct flame or
to be placed near any heating appliance. A
refrigerant container must not be heated above
50°C.
WARNING: Do not leave a container of
refrigerant without its cap fitted. Do not
transport a container of refrigerant that is
unrestrained, especially in the boot of a car.
