Needle Difficulties

Prevent bodily injury or death. Never work on the machine while it is running. Driveline can continue turning after disengaging PTO. Stay clear of the machine until it has come to a complete stop. Shut off engine, remove key from ignition, set parking brake, and engage the flywheel brake before repair or servicing.

Only restart the machine once the cause is identified and resolved.
