checked for compatibility to the supply voltage prior to
final electrical connection. Consult local and national
electrical codes regarding supply wiring requirements.

occur during shipment and it is very important that all
fasteners are secure, This is very important on the
bearings and propellers. Manually rotate the propeller
by hand to make sure it turns freely and does not
