PRECAUTIONS FOR ENGINE OILSNBGI0001S05Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner
as soon as possible.
Health Protection PrecautionsNBGI0001S0501IAvoid prolonged and repeated contact with oils, particularly
used engine oils.
IWear protective clothing, including impervious gloves where
practicable.
IDo not put oily rags in pockets.
IAvoid contaminating clothes, particularly underpants, with oil.
IHeavily soiled clothing and oil-impregnated footwear should
not be worn. Overalls must be cleaned regularly.
IFirst Aid treatment should be obtained immediately for open
cuts and wounds.
IUse barrier creams, applying them before each work period, to
help the removal of oil from the skin.
IWash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations containing
lanolin replace the natural skin oils which have been removed.
IDo not use gasoline, kerosine, diesel fuel, gas oil, thinners or
solvents for cleaning skin.
IIf skin disorders develop, obtain medical advice without delay.
IWhere practicable, degrease components prior to handling.
IWhere there is a risk of eye contact, eye protection should be
worn, for example, chemical goggles or face shields; in addi-
tion an eye wash facility should be provided.
Environmental Protection PrecautionsNBGI0001S0502Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating sys-
tem must meet the requirements of HM Inspectorate of Pollution for
small burners of less than 0.4 MW. If in doubt check with the
appropriate local authority and/or manufacturer of the approved
appliance.
Dispose of used oil and used oil filters through authorized waste
disposal contractors to licensed waste disposal sites, or to the
waste oil reclamation trade. If in doubt, contact the local authority
for advice on disposal facilities.
It is illegal to pour used oil on to the ground, down sewers or drains,
or into water courses.
The regulations concerning pollution vary between regions.
PRECAUTIONS FOR FUELNBGI0001S06Use unleaded gasoline with an octane rating of at least 87 AKI
(Anti-Knock Index) number (research octane number 91).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Using a fuel other than that specified could adversely affect
the emission control devices and systems, and could also
affect the warranty coverage validity.
PRECAUTIONS FOR AIR CONDITIONINGNBGI0001S07Use an approved refrigerant recovery unit any time the air condi-
tioning system must be discharged. Refer to HA-144, ªHFC-134a
(R-134a) Service Procedureº for specific instructions.
