2. Use a special low clearance hydraulic jack, crane,
or another lift truck to raise the drive tire. Make
sure that the jack, crane, or other lift truck has the
correct capacity rating. The capacity must equal

electrical charge after the battery is disconnected.
To prevent electrical shock and personal injury,
discharge the capacitor before inspecting or
repairing any component. Wear safety glasses.
Make certain the battery has been disconnected.
