Power loss with Thor Alpino 8.5 logsplitter

[Richard Men]

I have a quarter share in a Thor Alpino logsplitter which has been brilliant fro processing firewood for several years. Recently, it has been losing power and struggles to split an y knotty wood. I have topped up the hydraulic oil, cleaned the magnetic filter and we always make sure the splitter is used on the level. Can anyone please suggest what the fault may be?

Are you sufficiently greasing the rail?

 Scrape the clag off and apply fresh.

 Can't hurt.

Has it ever had the oil changed? Might be an idea to drain it out and see what colour it is, manual probably says it should have been changed by now anyway.

not same splitter but had some issues with mine that made it slow

 

hydraulic filter was horrible so lots of slower,  a ram seal weeping, annoyingly had to get a bigger tank as original tank wasnt matched well to pump volume,, hydraulics place checked flow rate and was 19 litres a min at pump and way too small a tank so oil got hot and that kills performance 

 

now got a 60 litre tank and doesnt matter how long i run it, how hard logs are never tops 25 celcious in summer in full sun and never drops performance

 

but an oil/filter change will tell you a lot as a good start

What is in/on the magnetic filter will normally tell a tale.

To be honest, I just wiped it with a rag and didn't look at what was on it! All I remember is that it wasn't too caked.
