Special Service Tools EAS000FH
CAUTION:
●Every time the vehicle is lifted up, maintain the complete vehicle curb condition.
●Since the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up point on the rear side garage jack with a mission
jack or equivalent.
●Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the front side garage jack with a mission jack or
equivalent.
●Be careful not to smash or do not do anything that would affect piping parts.
Garage Jack and Safety Stand EAS000FI
WARNING:
●Park the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes,
tubes, etc. under the vehicle.
●Never get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.

WARNING:
●Situate vehicle on a flat and solid surface.
●Place chocks at front and back of rear wheels.
●For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:
●Always be careful to work safely, avoid forceful or uninstructed operations.
●Do not start working until exhaust system and engine coolant are cool enough.
●If items or work required are not covered by the engine main body section, refer to the applicable
sections.
●Always use the support point specified for lifting.
●Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.
●For supporting points for lifting and jacking point at rear axle, refer to GI-35, "Garage Jack and
Safety Stand" .
