position, and remove key from switch.

Never Let Anyone Ride on Attachment
Never let anyone ride on any work attachment, such as the
bucket, crusher, grapple, or clamshell (grab bucket). There is a
danger of the person falling and suffering serious injury.
IMPORTANT
When hydraulic system maintenance or service work must
be performed, be aware that accumulators in system store
fluid under pressure after system has been shut down. To
release hydraulic pressure in accumulators, operate control
with engine "OFF" until accumulator pressure is completely
dissipated.
