Changing Wheels

1. Set parking brake.
2. Move selector lever to

away by blocking wheels with
wheel chocks: When changing a
wheel on a hill, place chocks

opposite to the axle to be
worked on; on a level road,
place one chock in front of and
one behind of the wheel that is
diagonally opposite to the wheel
being changed.

the wheel bolts.
5. Clean jack supporting tube, if
necessary. (Jack tubes are be­
hind the front wheel housings
and in front of the rear wheel
housings.)
6. Insert jack arm fully into the
tube hole up to the stop. Posi­
tion the jack so that it will al­
ways be vertical as seen from

The jack is designed exclusi­
vely for jacking up the vehicle

used when working under the
vehicle.
