Hydraulic failure can allow openers to fall rapidly, causing injury or death. To avoid hazard, always lock openers in raised position before adjusting, lubricating, or servicing machine.

Inspect the hydraulic hoses frequently for wear or damage between the lift cylinders and hydraulic lock-up valves. Contact your John Deere dealer or qualified service provider for replacement hoses.
