WARNING:
+Position vehicle on a flat and solid surface.
+Place chocks at front and back of rear wheels.
+Do not remove engine until exhaust system has com-
pletely cooled off, otherwise, you may burn yourself
and/or fire may break out in fuel line.
+Before disconnecting fuel hose, release pressure.
Refer to EC-38, ªFuel Pressure Releaseº.
+Be sure to lift engine and transaxle in a safe manner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
+When lifting engine, be sure to clear surrounding parts.
Use special care near accelerator wire casing, brake lines
and brake master cylinder.
+When lifting the engine, always use engine slingers in a
