INSULATED.

NEVER use ladders, planks or other devices to increase the height of the platform.
NEVER attach overhanging loads to the platform or increase the platform size.
NEVER elevate the platform if it contains more than one person or more than the rated load (see specifica-

tions on back page).

LOOK up, down and around for overhead obstructions and electrical conductors.
NEVER change operating or safety systems.
NEVER use outriggers from one model on another model.
