I too am on my second Fischer Panda. I would not be so hard though.
I got 9 years out of the first one and except for corrosion
it would still be going strong.
They use different motors depending on the model genset. First one was a 6 KW with Kubota, second one 4.2 KW with Ferryman.
Weak points- external electrical box with capacitors and curcuit boards, don't let it get wet at ALL. It must be mounted in the proper orientation also or the toroids will tear loose.
This only applies to older units like my first one (vintage 1999), They used water cooling
for the engine
and generator section BUT the generator section was salt water
cooled and the engine
had a heat exchanger
All new units are cooled with antifreze throughout then going through a common heat exchanger
The good things about Pandas- they are small and light for the output and do not have to be de-rated when put into a sound enclosure.
The head gasket
problem? Every diesel
engine needs to have the head bolts re-torqued after the first 50 hrs and then periodicaly thereafter.
Get a Panda Tech to do the work!!!!
