Boom Stop Operation and Adjustment (6) 
The Boom Stop system stops the boom winch from hauling-in when the boom is vertical, preventing overloading of key 
machine components. Defeating the boom stop valve could result in serious equipment damage, personnel injury, or even 
death. Its operation must be check and verified daily. 
Safety message (6) is located on the left side of the crossmember support, at the front, on the boom stop valve access panel.

Tipover Hazard (7) 
The machine may tip and personal injury may occur if the maximum load capacities are exceeded. Load capacities 
assume that the machine is stationary on a level concrete surface with the counterweight extended. Lift capacities will 
decrease on slopes or soft ground. See Operation and Maintenance Manual "Lifting Capacities". 
Safety message (7) is located on the left hand console.
