Lift Cylinder Lock-Out Valves
To prevent unintentional raising or lowering of the rotary disc pull-type, engage the lift cylinder lock-out valves before
servicing, repairing, or unplugging your machine. The lift cylinder lock-out valves are located on the lift cylinders at the back
of the rotary disc pull-type.

Engaging Locks
DANGER
To avoid bodily injury or death from unexpected start-up or fall of a raised machine, stop engine, remove key, and
engage lift cylinder lock-out valves before going under machine for any reason.
IMPORTANT:
Connect hoses so that moving the cylinder control lever backward raises the rotary disc pull-type, and moving the cylinder
control lever forward lowers the rotary disc pull-type. Refer to
