Maintenance
Section 4
4.1 — Maintenance
NOTE: Proper maintenance is necessary for safe operation and is crucial to the life of the generator. Genuine
Generac parts MUST be used to ensure warranty coverage
NOTE: Since most maintenance alerts occur at the same time (two or four year intervals), only one will appear
at any one time. Clearing one will cause the next active alert to be displayed.
4.2 — Maintenance Kits
To maintain the warranty, genuine Generac replacement parts MUST be used, including Generac oil kits (which include
both an oil filter and an air filter). Generac oil kits can be obtained through an Authorized Dealer or purchased on-line.
To purchase on-line, access the maintenance kits page through www.generac.com. Follow the prompts to enter deliv-
ery information and complete the purchase.
All Generac oil kits meet minimum American Petroleum Institute (API) Service Class SJ, SL, or better. Use no special
additives. Select the appropriate viscosity oil grade according to the expected operating temperature. Synthetic oil also
can be used in the appropriate weight as standard.
4.3 — Service Maintenance Schedule
NOTE: Use only Genuine Generac parts to ensure warranty coverage.
*
All generator service must be performed by a qualified service person only.
It is important to perform all maintenance at the interval specified in the Service Maintenance Schedule. This ensures
safe and proper operation, as well as compliance with applicable emissions standards. Critical emissions maintenance
must be performed for the Emissions Warranty to remain valid. Service and repairs may be performed by any qualified
service technician or repair shop.
The LCD screen prompts the user when it is time to perform the Schedule A or Schedule B maintenance tasks.
When performing Schedule B maintenance, first perform all tasks listed under Schedule A maintenance.
Observe the maintenance tasks and intervals shown in Table 4-1.
IMPORTANT NOTE: The secondary 12V DC fan continues to operate for up to one hour after the generator is
shut down. Proper cooling must occur before removing battery connections for maintenance or other ser-
vice activity.
+
If utility is present, the secondary 12V DC fan continues to operate for up to one hour after the gen-
erator is shut down (even if the 7.5 amp ATO fuse is removed). To avoid hand injury, always exercise
caution when working near the AVR fan housing.
