PORTABLE STARTING UNIT
There are many types of portable starting units
available for starting engines. Follow the manufac-
turer's instructions when involved in any engine
starting procedure.
HOISTING RECOMMENDATIONS
FLOOR JACK
When properly positioned, a floor jack can be used
to lift a Jeeptvehicle. Support the vehicle in the
raised position with jack stands at the front and rear
ends as applicable (Fig. 7).
CAUTION: Do not attempt to lift a JeepTvehicle
with a floor jack positioned under:
²an axle tube,
²a body side sill,
²a steering linkage component,
²a drive shaft,
²the engine or transmission oil pan,
²the fuel tank, or
²a front suspension arm.
Use the correct sub-frame rail or frame rail
lifting locations only (Fig. 7).
HOIST
A Jeeptvehicle can be lifted with a swiveling-arm
type hoist; with a wheel-lift, twin-post hoist; or with
a ramp-type, drive-on hoist.
When a swiveling-arm, frame-contact type
hoist is used, ensure that the lifting pads are po-
sitioned at the correct sub frame rail (Fig. 7).
TOWING RECOMMENDATIONS
TOWING EQUIPMENT
A vehicle equipped with SAE approved sling-type
towing equipment can be used to tow all Jeeptvehi-
cles (Fig. 8). When it is necessary to rear-tow a vehi-
cle, use the wheel-lift towing method with a tow
dolly located under the front wheels. A vehicle with
flat-bed towing equipment can also be used to trans-
port a disabled vehicle.
A wooden crossbeam with spacer blocks could pos-
sibly be required for proper connection when using
the sling-type, front-end towing method (Fig. 9).
SAFETY PRECAUTIONS
The following safety precautions must be consid-
ered when preparing for and during a vehicle towing
operation:
