+Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
+Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
+Replace inner and outer races of tapered roller bearings and
needle bearings as a set.
+Arrange the disassembled parts in accordance with their
assembled locations and sequence.
+Do not touch the terminals of electrical components which use
microcomputers (such as ECMs).
Static electricity may damage internal electronic components.
+After disconnecting vacuum or air hoses, attach a tag to indi-
cate the proper connection.
+Use only the ¯uids and lubricants speci®ed in this manual.
+Use approved bonding agent, sealants or their equivalents
when required.
+Use tools and recommended special tools where speci®ed for
safe and efficient service repairs.
+When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
+Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do
not carelessly disconnect the harness connectors which are
related to the ECCS system and TCM (Transmission Control
Module) system. The connectors should be disconnected only
when working according to the WORK FLOW of TROUBLE
DIAGNOSES in EC and AT sections.
Precautions for Multiport Fuel Injection System
or ECCS Engine
+Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM (Engine Control
Module):
Turn ignition switch to ``OFF'' position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
+
Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
+Be careful not to jar components such as ECM and mass air
¯ow sensor.SGI787
PRECAUTIONS

GI-3

Precautions for Three Way Catalyst
(If so equipped)
If a large amount of unburned fuel ¯ows into the catalyst, the cata-
lyst temperature will be excessively high. To prevent this, follow the
instructions below:
+Use unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
+When checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
+Do not run engine when the fuel tank level is low, otherwise the
engine may mis®re causing damage to the catalyst.
Do not place the vehicle on ¯ammable material. Keep ¯ammable
material off the exhaust pipe and the three way catalyst.
Precautions for Engine Oils
Prolonged 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 PRECAUTIONS
+Avoid prolonged and repeated contact with oils, particularly
used engine oils.
+Wear protective clothing, including impervious gloves where
practicable.
+Do not put oily rags in pockets.
+Avoid contaminating clothes, particularly underpants, with oil.
+Heavily soiled clothing and oil-impregnated footwear should not
be worn. Overalls must be cleaned regularly.
+First Aid treatment should be obtained immediately for open
cuts and wounds.
+Use barrier creams, applying them before each work period, to
help the removal of oil from the skin.
+Wash 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.
+Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or
solvents for cleaning skin.
+If skin disorders develop, obtain medical advice without delay.
+Where practicable, degrease components prior to handling.
+Where there is a risk of eye contact, eye protection should be
worn, for example, chemical goggles or face shields; in addition
an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Burning 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.
PRECAUTIONS
GI-4

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.

2-pole Lift
WARNING:
When lifting the vehicle, open the lift arms as wide as possible and ensure that the front and rear of
the vehicle are well balanced.
When setting the lift arm, do not allow the arm to contact the brake tubes and fuel lines.
Put the attachment in the slit of the lift pad to prevent the frame from
slipping.
Use suitable stands at the correct places as illustrated, to prevent
the vehicle from becoming unbalanced.
