Lock-Up Rockshafts and Openers

CAUTION: 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.

IMPORTANT: Hydraulic hoses between the lift cylinders and hydraulic lock-up valves should be inspected frequently for leakage, kinking, cuts, cracks, abrasion, blisters, corrosion, exposed wire braid or any other signs of wear or damage prior to working under a raised implement. Worn or damaged hose assemblies can fail during use and should be replaced immediately. Failure to do so may result in serious injury or death

Fully raise openers and close lock-up valve (A).
