Merlo issues

[Eddynantcribba]

Has anyone had trouble with Merlo (30.7) not moving on occasion? Sometimes works perfect, but the next day won’t go at all, or just works for five minutes , then stops. Sometimes even just move one direction, but not the other. Eg: i tried several times Sunday, and it would not move at all. Monday, it worked perfectly for the hour or so that I used it. All other hydraulic system works, and when I put it in reversed the beeper works, so I assume it “thinks” its working.

My 26.6 spt did this last week.

I use mine with the over load switched off , so the red warning light should always be flashing.

However when I lost drive , I noticed it was know longer flashing , and changing the bulb got me going again.

I'm sure a 30.7 has a different over load system ,but it just goes to show how a trivial and seemingly unrelated fault can disable a machine.

What age is the machine? I’m presuming 1995-1999 ish. You need to check the drive ecu if it has sauer transmission for errors first. Black box with green, orange and red lights on. Usually just inside cab on the left up under dash panel or behind brake reservoir on the right.

Hi if you hit it and it works you are on borrowed time. They can be repaired usually rather than £1500 for a new one. I usually have a service exchange unit in stock

@Eddynantcribba Did you get the problem sorted?
My 32.6 had a big issue last summer with moving forward or backward when the Boom was at about 10-15 deg never got to the bottom of the problem but as Autumn came it seem to be OK but just recently its started happening again. Cant be anything to do with moisture as its as wet now as it was ever.

OK, I'll put some contact lub in the 28-pins connectors both sides and check if it's better. If not I'll get back to you.

Good Evening !

As I said last night, contact lubricant didn't resolve anything
A big hit must still be done on the case to make the 2 upper leds lit and the merlo drive

Could you send me a quotation for repairing this faulty ECU ?

Any contact in France ?

MERLO 28.7 EVT Year 1997

Thank you
Regards.
