NOTICE TO USERS OF THIS MANUAL
This SERVICE MANUAL has been written and published by Generac to aid our dealers’ mechanics and company
service personnel when servicing the products described herein.
It Is assumed that these personnel are familiar with the servicing procedures for these products, or like or similar
products manufactured and marketed by Generac. That they have been trained in the recommended servicing
procedures for these products. Including the use of common hand tools and any special Generac tools or tools
from other suppliers.
Generac could not possibly know of and advise the service trade of all conceivable procedures by which a
service might be performed and of the possible hazards and/or results of each method. We have not undertaken
any such wide evaluation. Therefore, anyone who uses a procedure or tool not recommended by Generac must
first satisfy himself that neither his nor the products safety will be endangered by the service procedure selected.
All information. Illustrations and specifications in this manual are based on the latest product information
available at the time of publication.
When working on these products, remember that the electrical system and engine Ignition system are capable
of violent and damaging short circuits or severe electrical shocks. If you intend to perform work where electrical
terminals could be grounded or touched, the battery cables should be disconnected at the battery.
Any time the Intake or exhaust openings of the engine are exposed during service, they should be covered to
prevent accidental entry of foreign material. Entry of such materials will result In extensive damage when the
engine Is started.
During any maintenance procedure, replacement fasteners must have the same measurements and strength as
the fasteners that were removed. Metric bolts and nuts have numbers that indicate their strength. Customary bolts
use radial lines to indicate strength while most customary nuts do not have strength markings. Mismatched or
Incorrect fasteners can cause damage, malfunction and possible injury.

The use of replacement parts that are not In compliance with such Rules and Regulations could result In a fire or
explosion hazard. When servicing this equipment it is extremely important that all components be properly
Installed and tightened. If improperly Installed and tightened, sparks could ignite fuel vapors from fuel system
