OVERLOWERING INTERRUPT AND
OVERRIDE
WARNING
When lifting after using the override feature,
verify that chains, hoses, and cables are not ob-
structed in any way.
An overlowering interrupt feature is incorporated
on models 553 and 558. The overlowering interrupt
function prevents further lowering of attachment
when both end beams have been raised in relation
to outer booms. This prevents slacking of chains,
hoses, and wires over the mast. It also reduces shock
on attachment. The blue LED in operator’s cab will
illuminate when lowering interrupt is activated.
To override overlowering interrupt feature, turn
override key switch clockwise and push override
button while using lowering lever.
