If you do not understand any portion of this manual, contact Generac or the nearest Generac/Guardian Authorized Dealer for starting, operating and servicing procedures.

Throughout this publication, and on tags and decals affixed to the generator, DANGER, WARNING, CAUTION and NOTE blocks are used to alert you to special instruction about a particular operation that may be hazardous if performed incorrectly or care- lessly. Observe them carefully. Their definitions are as follows:

After this heading, read instructions that, if not strictly complied with, could result in damage to equipment and/or property.

NOTE:

These safety warnings cannot eliminate the hazards that they indicate. Common sense and strict compli- ance with the special instructions while performing the service are essential to preventing accidents.

Four commonly used safety symbols accompany the DANGER, WARNING and CAUTION blocks. The type of information each indicates is as follows:
