Shut down and disconnect Load Bank from
auxiliary power source before inspecting,
maintaining, or servicing.
MOVING PARTS can cause serious injury.
•
Keep clear of moving parts.
HOT SURFACES can cause severe burns.
•
Allow cooling period before servicing.
Maintenance to be performed only by qualified
