Adjust HIGH IDLE:

The Engine is Preset at factory. Contact Perkins @ 1-888-737-5364 or www.perkins.com

Adjust LOW IDLE:

First make sure there is no load on the machine. Set the IDLE switch to AUTO and wait for the engine to change to low idle speed.

Use the 7/16” wrench to loosen the solenoid idle rod locking nut. See Figures F.13 & F.14 Turn the rod to change the amount of throw in the lever arm, until the tach reads between 1375 and 1425 RPM. Retighten the locking nut. Make sure the lever arm does not contact low speed adjustment stop. Back stop out if necessary.
