PREPARING THE UNIT

UNPACKING

CAUTION: EQUIPMENT DAMAGE

When you unpack your new generator, be sure to remove 
all of the information sheets and manual from the carton.

1. As you receive your unit, it is critical to check it for any 
  damage. If any damage is noted, it is always easiest to 
  refuse the shipment and let WINCO take care of the 
  freight claim. If you sign for the unit, the transfer of the 
  ownership requires that you file the freight claim

2. Before proceeding with the preparations of your new 
  generator for operation, take a couple of minutes to 
  ensure the unit you have received is the correct model 
  and review the specification pages in this manual to 
  ensure that this unit meets your job requirements.
