Storage
Never crawl under or allow children to play around or on a loader that is disconnected from
the tractor. The loader could fall crushing a person resulting in serious injury or death.
(SL-13)
Do not remove the attachment from the loader when the loader is disconnected from the
tractor. The attachment stabilizes the loader. If the attachment is removed, the loader will
fall and could result in serious injury.
(SL-26)
Only disconnect and store the loader on firm flat ground. Make sure the loader stands are
properly installed and rest on firm ground or support blocks. If the stands sink or fail, the
loader could fall causing serious injury.
