the chassis tie-down lugs.
Fully lower platform and shut off all power before leaving machine.
Remove all rings, watches, and jewelry when operating machine. Do not wear loose
fitting clothing or long hair unrestrained which may become caught or entangled in

thermal movement can include the length of time the machine will remain
stationary, hydraulic oil temperature, ambient air temperature, and platform
position.
