• In the event of power loss, control system failure or other malfunction, boom lowering
functions may be accomplished manually.
• To manually operate boom retraction, and turntable rotation functions, use the hand pump,
and "motion selection" valve on the hydraulic pump unit that can be accessed inside the
pump compartment.
• Manual lowering of the boom and platform may also be performed by actuating the valve
plunger found on the base of each boom lift cylinder. Pushing in and holding the valve
"button" on the appropriate cylinder retracts that cylinder, thereby retracting that part of the
boom. The boom may need to be rotated to a clear area before lowering.
Prior to operation :
• Read, understand and obey all instructions and safety precautions in this manual and
attached to the aerial work platform.
• Read, understand and obey all Federal, State and local codes and regulations.
• Become familiar with the proper use of all controls and emergency systems.
