I have a blocked oil output on a Dynamac chainsaw- electric 19e type.
Would anyone know how the system works

Is the pump a thread on the spindle or what- any ideas on how to clear it.
Do you know if the oil co-agulates or goes solid when left in long ?

I haven't tried a thinner oil wash- is this likly to work- without the chain of course to clear only.

Or should I dump it- from up a tree :D

Or should I use it to drive me motorbike.

I guess the sound of silence means no guesses, or else nobody knows.
What what!- I am good with mechanics but didn't want to strip the equipment any further than at present.
I don't have an air pressure setup to try blowing out the blockage.

Cheers for any ideas.

Do I get out the handsaw ?- I use a bowsaw for most of my work- they're great.
So sorry to neglect you! :oops:
Chainsaw pumps are simple and reliable - its the oil passages to and from them thats an issue. I can't speak for Dynamac, but on petrol gear we run a mixture of petrol / paraffin (anything thats thin, really) through the oil tank and this sometimes gives us a break. The oil tank filter rarely blocks. If that doesn't work, its a stripdown to access the pump for a thorough clean. This is where the cheaper Stihl's got it wrong!
In the meantime, dip the cutter bar in a bowl of oil when you use it and it'll come to no harm.

Hi !
Now it's my turn- sorry for the late reply- had a busy time.
Mind you- spiced up a bit with a great carvery meal out :D
Thanks- that information gives me a good guide, really it's a good help.

I'd rather try flushing than stripping out any more, that would entail taking off a bearing on the electric drive motor I think.

Thanks John
A good post, regards
