Dispose of used oil and used oil ®lters 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 the pollution of the environment
will vary from country to country.
Precautions for Fuel
GASOLINE ENGINE:
Three way catalyst equipped models ... unleaded gasoline of at
least 91 octane (RON)
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Except for the above models ... unleaded or leaded gasoline of
above 88 octane (RON)
Use unleaded fuel if instructed on the fuel ®ller lid.
DIESEL ENGINE*:
Diesel fuel of above 45 cetane for TD42 engine and above 50 cet-
ane for RD28ET engine
* If two types of diesel fuel are available, use summer or winter
fuel properly according to the following temperature conditions.
+Above þ7ÉC (20ÉF) ... Summer type diesel fuel.
+Below þ7ÉC (20ÉF) ... Winter type diesel fuel.
CAUTION:
+Do not use home heating oil, gasoline, or other alternate
fuels in your diesel engine. The use of those can cause
engine damage.
+Do not use summer fuel at temperature below þ7ÉC (20ÉF).
The cold temperature will cause wax to form in the fuel. As
a result, it may prevent the engine from running smoothly.
+Do not add gasoline or other alternate fuels to diesel fuel.
Precautions for Air Conditioning
Use an approved refrigerant recovery unit any time the air condi-
tioning system must be discharged. Refer to HA section (``HFC-
134a (R-134a) Service Procedure'', ``SERVICE PROCEDURES'')
for speci®c instructions.
