RESPONSIBILITIES (ANSI A92.6) before operating or performing maintenance on
any UpRight aerial work platform.
SAFETY RULES
NEVER operate the machine within ten feet of power lines.
THIS MACHINE IS NOT INSULATED.
NEVER operate the machine without first surveying the work area for surface hazards such as holes, drop-
offs, bumps and debris. NEVER operate the machine if all guardrails are not properly in place and secured with all fasteners properly
installed.
SECURE and lock gate after mounting platform. NEVER use ladders or scaffolding on the platform. NEVER attach overhanging loads or increase platform size. MAINTAIN tire pressure at 65 psi (unless foam filled). Check daily. LOOK up, down and around for overhead obstructions and electrical conductors. DISTRIBUTE all loads evenly on the platform. See the back cover for maximum platform load. NEVER use damaged equipment. (Contact UpRight for instructions. See toll-free phone number on back
cover.)
NEVER change operating or safety systems. INSPECT the machine thoroughly for cracked welds, loose hardware, hydraulic leaks, damaged control cable,
loose wire connections and wheel bolts.
NEVER climb down elevating assembly with the platform elevated. NEVER perform service on machine while platform is elevated without blocking elevating assembly. NEVER recharge battery near sparks or open flame; batteries that are being charged emit highly explosive
hydrogen gas.
AFTER USE secure the work platform against unauthorized use by turning key switch off and removing key. NEVER replace any component or part with anything other than original UpRight replacement parts without
the manufacturer's consent.
NEVER elevate or drive elevated on uneven slopes or soft ground or elevate the platform unless the platform is level.
