Merlo third service??

[Cmoran]

I’ve a new to me 2007 merlo everything works except the third function and the pick up hitch could anyone tell me where to start. I’ve attached two pictures of a switch and handle I’m not sure what they are for also. Thanks

On our 2015 32.6 the lever at the top of your second pic does the rear pick up hitch.

That seems to boom in and out on mine unless there’s a change over valve?

Take it there’s no switches on the joystick? Have you got a photo which shows more of the controls?

One roller should be boom in out, other third service. cables can come loose or damaged under the lever sometimes. You may have to start testing

Do you have a pick up hitch?
On my 2008 32.6 there is a T handle on the end of a wire cable sticking through the hole next to the knob on your second picture, which locks/unlocks the hitch. I’m pretty sure the knob next to it is a dump valve for the rear hydraulics, not that I’ve ever used it.

Pickup hitch should be the lever that just had a bit of thread on the end. For the 3rd srevice its the roller switch on the joystick next to boom in/out. Try the green switch in front of the joystick in different positions. One way could be constant pumping. Failing that the roller switches can go wrong. You can swap two plugs, underneath between cab and chassis, that swaps the two roller switches over. So if tje boom in/out still works on the other switch you know if the switch is working or not.

Thanks I’ll try that. The lever with the thread is working boom in and out which is the left roller on my joystick aswell. Maybe it has been swopped already?

The top poll has a constant 12 volts but no power anywhere else when using any switch

That's probably the hydraulic lockout solenoid, the ones you want are underneath the valve block with a different type of plug to that

My mistake, I’m just sat on mine now. The missing knob in the second picture is the temp control for the heater. The pick up hitch cable is further back.

I don’t have the other switch on mine (32.6), but presumably a locking switch for something.
Does yours have boom suspension? Is it the lock out for that (guessing the decals are accumulators)?

Perfect I’ll look again tomorrow thanks

The green switch with 3 positions is part of it. But looks as if someone has fitted a button beside it. With the lever that’s screwed in fir boom in/out suggests the machine has some issue electrically. I will pm my number I may be able to help guide through a few things to check

I think you need the manual
