Schliesing 200 mx roller problems

[Ichip]

Hi all, i have a Schliesing 200mx.

 

When i feed the machine the no stress and rollers work fine and then without any reason the rollers will slow down as if there are not enough revs.

 

If i knock the throttle down and rev it up again it works again but will the rollers will intermittently slow down so i have to go through the throttle process again.

 

Can anybody shed any light on this please?

 

Could it be faulty wiring to the solenoid or possibly be the solenoid itself?

 

Thanks in advance.

solenoids are on or off unless its got a proportional set up i would think your issues are hydraulic stick a pressure gauge on it and see whats join on

Thanks for he quick reply. I have disconnected the earth from the solenoid and the rollers run fine but has no stress control could it still be hydraulic?

I managed to find out what was wrong. As the engine got 1450rpm this would cut the rollers.
