How do you adjust the lift arm to travel further up when on auto works fine on manual but won't lift the bale quite far enough on auto to sit it on the table.

Haven't got one but I'm guessing there's a magnetic switch/ sensor to tell the box when it's at the top of its travel and it needs moving / adjusting.

Not 100% sure but I think it's a hydraulic pressure sensor, they can be adjusted but it probably needs replacing

Are you sure you're not trying to load it with the table on horizontal?

Switch it to manual and make sure the table is tipped forwards (with the manual table tip off button).
Switch back to 'Auto' and try again.

Once you get it into sequence, the table should always return to that 'leaning forward' position when in Auto.

Try adjusting the oil flow.it’s critical.if incorrect that’s a symptom

Try again with a few revs on, think it’s timed so if not enough oil it travel far enough

Yep have table leaning forward works fine on manual but on auto the lift arm does travel quite far enough.

Done all that doesn't change it the lift arm on auto doesn't travel far enough.

Could also check the spring in the lift ram…should ride above ground when down but bounce if you stand on it .if it breaks it may foul inside and stop full travel of ram as it’s in the cylinder.had a few break.not had one stop it lifting tbh but it could in theory.

 

[s~~t shoveller]

But oil flow is certainly critical.presume you’ve a proper free flow return

I'd go with oil flow then, which may be caused by not having enough revs on. (Ours won't cut and hold properly on tick over).

I agree with you but where as I can't find one or does it work off a relief valve as it will sit the bale on the roller of the table but doesn't quite travel far enough to sit it completely on the table , works fine on manual.

Does it lift at the same speed on manual as auto?
If not, I'd still be inclined to say oil flow.

Lifts at same speed

I’ve always thought it was a timed action.
I.E it lifts for 1.5 seconds so if it’s not pumped enough oil in that time it won’t lift high enough.
You should be able to change the duration in the control box setting but might need the access code to get in

I wondered that and if it's timed that would answer the problem so I will try the local agent for the code cheers

Have a play about with the box. There’s lots of settings you can change

It does seem a bizarre way to regulate the position of a lifting arm. Too many variables with tractor revs,oil thickness or temperature,wear in fittings etc. Why not just a position sensor?

Lots of wrappers have used that system for years. Tip function is often same

On my inline 991c, it's a pressure sensor, I would ring mchale and ask, they are helpful if you can understand the accent
