Injector FORD FIESTA 2007 Workshop Manual

100-00-1 3 General Information 100-00-1 3
DESCRIPTION AND OPERATION
Do not use damaged or defective tools or
equipment, particularly high-speed equipment such
i as grinding wheels. A damaged grinding wheel can
disintegrate without warning and cause serious
injury.
Wear suitable eye protection when using grinding,
chiseling or sand blasting equipment.
Wear a suitable breathing mask when using
abrasive blasting equipment, working with
asbestos-based materials or using spraying
equipment.
Make sure there is adequate ventilation to control
dusts, mists and fumes.
High Pressure Air, Lubrication and Oil
Test Equipment
See also Lubricants and Greases.
Always keep high-pressure equipment in good
condition, and regularly maintained, particularly at
joints and unions.
Never direct a high-pressure nozzle, for example
diesel injector, at the skin as the fluid may
, penetrate to the underlying tissue, and cause
serious injury.

See CFCs.
Legal Aspects
There are many laws and regulations relating to
health and safety in the use and disposal of
materials and equipment in a workshop.
For a safe working environment and to avoid
environmental pollution, workshops should be
familiar, in detail, with the many health and safety
laws and regulations within their country, published
by both national and local authorities.
Lubricants and Greases
Avoid all prolonged and repeated contact with
mineral oils. All lubricants and greases may be
irritating to the eyes and skin.

Transmission Fluids
Safety instructions
Certain Transmission and Power Steering fluids
supplied to Ford may contain additives which have
the potential to cause skin disease (dermatitis) to
exposed persons. The dermatitis may be irritant
or allergic in nature. Risks are higher where
prolonged or repeated skin contact with a fluid may
occur. These fluids are used for vehicle initial
fill
and service purposes. This sub-section is to:
Inform Service personnel who may come into
contact with these vehicle fluids (hazard
communication).
Summarise appropriate workplace control
measures and personal protective equipment
requirements.
Draw attention to the existence of Material
Safety Datasheets (MSDS's) for the fluids
(available from Ford Customer Service Division).
These MSDS's contain detailed information on
hazards and appropriate controls.
Control measures
Workplace risk assessments made under national
chemical control regulations should identify
operations involving the fluids as potentially
hazardous and specify workplace control and
worker awareness measures. In such
circumstances, the relevant Material Safety
Datasheet (see the details specified below) which
specifies hazards and control measures in detail
should be made available for guidance.
Avoid unprotected skin contact with the fluids, and
in particular, avoid prolonged or repeated skin
contact. Work practices should be organised so as
to minimise the potential for skin contact. This may
include the use of drip trays, absorbents, correct
fluid handling equipment (funnels etc), and
workplace housekeeping measures such as the
cleaning of contaminated surfaces.
Personnel engaged in operations where skin
contact could occur (such as fluid draining or filling)
should wear impervious gloves made from
nitrile
rubber, certified to a chemical protection standard,
e.g. Europe Standard EN374. This glove type is
widely available from reputable suppliers of gloves
for chemical protection [including the manufacturers
Ansell-Admont
(Solvex Range), North Safety
products (North
Nitrile Latex Gloves range), and
