ESCRIPTION

The X26 Ultra Narrow Work Platform is a self-propelled aerial work platform designed to provide mobility
with the platform elevated or lowered. The elevating function shall only be used when the platform is on a
firm, level surface. Travel with the platform elevated is limited to the low speed range. The machine is
intended to be self-propelled only when in relatively close proximity to the work area.
