WARNING:
• Situate vehicle onaflat and solid surface.
• Place chocks atfront andback ofrear wheels.
• Donot remove engineuntilexhaust systemhascompletely
cooled off.
Otherwise, youmay burn yourself and/orfiremay break out
in fuel line.
• For safety during subsequent steps,thetension ofwires
should beslackened againsttheengine.
• Before disconnecting fuelhose, release fuelpressure from
fuel line.
Refer to"Releasing FuelPressure" inEC section.

• For engines notequipped withengine slingers, attach
proper slingers andbolts described inPARTS CATALOG.
CAUTION:
• When liftingengine, becareful nottostrike adjacent parts,
especially thefollowing: Accelerator wirecasing, brake
lines, andbrake master cylinder.
• Inhoisting theengine, alwaysuseengine slingers inasafe
manner.

SEF289HSGI233
SGI234 PRECAUTIONS
General Precautions (Cont'd)

• Before jacking upthe vehicle, applywheel chocks orother
tire blocks tothe wheels toprevent thevehicle frommov-
ing. After jacking upthe vehicle, supportthevehicle weight
with safety stands atthe points designated forproper lifting
before working onthe vehicle.
These operations shouldbedone onalevel surface.
• When removing aheavy component suchasthe engine or
transaxle/transmission, becareful nottolose your balance
and drop them. Also,donot allow themtostrike adjacent
parts, especially thebrake tubesandmaster cylinder.
• Before starting repairswhichdonot require batterypower:
Turn offignition switch.
Disconnect thenegative batteryterminal.
• Toprevent seriousburns:
Avoid contact withhotmetal parts.
Do not remove theradiator capwhen theengine ishot.
• Before servicing thevehicle:
Protect fenders, upholstery andcarpeting withappropriate
covers.
Take caution thatkeys, buckles orbuttons donot scratch
paint.
• Clean alldisassembled partsinthe designated liquidor
solvent priortoinspection orassembly.
• Replace oilseals, gaskets, packings, O-rings,locking
washers, cotterpins,self-locking nuts,etc.with newones.
• Replace innerandouter races oftapered rollerbearings
and needle bearings asaset.
• Arrange thedisassembled partsinaccordance withtheir
assembled locationsandsequence.
• Donot touch theterminals ofelectrical components which
use microcomputers (suchasECMs).
Static electricity maydamage internalelectronic compo-
nents.
