All easy DIY! In this video, I cover all the general maintenance of the Harbor Freight Predator 3500w generator + other variants and private labels listed bottom of this text. This gen has served our family very well! If you want your gen to last, keep up with it. As with any mechanical device, if you do not schedule in time for maintenance, the machine will schedule maintenance for you. Put it on your schedule.

This covers any generator running a honda or honda clone hemi motor such as..
- Echo Bear Cat IG3500
- Powerhorse LC3500i
- BE i3500L
- Loncin LC3500i
- Atlas Copco P3500i
- JET JIN3500E
- DR PRO 3500i
- And of course the much loved Predator 3500
(Probably 10 other private labels too..)
