What do you need doing?

Hi Andy

 

The anti stress is playing up. It takes some time after start up for it to kick in at first I thought it could have been the battery or alternator but both have been checked out and both where fine. Im sure its the type that runs of the alternator not a speed sensor. Greenmech have explained what to check but im no good with electrics. Do you know anyone mate?

 

Thanks

Sorry, I don't know much about those without seeing it. Does the control box display chipper revs when the machine is running?

[jimthedog]

It has an led. It used to turn green when the engine is up to speed and the anti stress kicked in. Now it is red with a flash of green every 3 sec roughly. When the anti stress starts up it's sold green. I was thinking it might be engine speed related but I'm not sure what it should be or how to check it.

You shouldn't need a specific chipper mechanic to diagnose the engine not reaching max revs, anyone handy with engines should be able to play around with the throttle stops to see if lifting the revs solves your problem. Alternatively the no stress control can pick up the rotor speed from a sensor reading a toothed ring mounted on the flywheel driveshaft. If the sensor gap is too great the readings can be incorrect. More likely the drive belts are slipping then the rotor doesn't reach the required speed and the no stress doesn't work. If the speed feed comes from the alternator also check that the fan belt isn't slipping, allowing an under speed at the alternator. All of this can be checked by anyone with a bit of mechanical knowledge - let us know how you get on!

All belts are good and tight. I will play with the engine speed and if that work s. Just worried about over doing it.

have you checked the air and fuel filters?
