NOTICE: A bucket mounted on the quick coupler has a longer overall teeth radius. Always check the operating range
of the machine with the Coupler bucket. Avoid abrupt operation in order to keep proper clearance between the bucket
and the cab or boom or other significant parts of the machine.
NOTICE: A bucket mounted on the quick coupler has a longer overall teeth radius. Therefore, the bucket cannot
be fully curled after the arm has been fully retracted, and the overall height of the machine in the transport position
is increased. The recommended operating practice is to remove the bucket from the coupler before any transport
operation in order not to increase the overall height of the machine.
