DESCRIPTION
Scheduled  maintenance  is  a  necessity  for  all  standby  generators.  The  Air 
Cooled  Scheduled  Maintenance  kits  offer  all  the  hardware  necessary  to 
perform a complete maintenance on Generac air-cooled generators.  Oil  will 
need  to  be  purchased  separately  based  upon  the  recommendations  listed.  
Maintenance is recommended at every 200 hours or 2 years.  If running in a 
dusty environment, more frequent maintenance may be required. Maintenance 
intervals may differ per model. Refer to the generator owner's manual for more 
information.
