Eco arborist 15 23/26 rpm?

[billpierce]

Cant find what the running rpm should be? Manual says speed is 2300rpm . When throttle is right down it makes about 1250rpm, throttle linkage appears to be fine and has full articulation both on the lever and on throttle on engine.

 

The run button on the ECU does nothing, I know on some greenmech this will increase rpm, but don't know if this should work or is just there as it's a standard controller across models.

 

Either way it chips fine and I would say you notice it chipping slowly compared to say a tw150 etc. Just checking its revving out correctly. It's the isuzu 3Lb1 3 pot non turbo

Hi Bill 

From memory they ran at 2400-2450 rpm , which is actually flywheel rpm.

I cant see from your pictures if the arm is actually touching the set screw at full throttle ?

If it is then I would be checking the air cleaner and fuel filter..

Filters are a few months old and clean. Yes throttle is down on the adjust screw. Honestly it chips well and works fine. The idle rpm is about 550. Could it be the rpm sensor is goosed?

Bill , do the revs on the display remain fairly constant at any given throttle position ?

If so I would say the sensor is ok.

The sensor gap should be 1.0 to 1.5mm .

Bill , does it have an EHB ignition box fitted ?

That's the black ignition box with the ignition switch built into the box and idle , set and run buttons ?

It sounds like it might need re-programming.

That's a simple job over the phone and we can send you the setting info should you need to do it again in the future..

Give us a call on 01789400044..

All sorted, rang the workshop, went through the ECU reset. Even got the no stress working!

Many thanks, great service!
