Sprayinghydraulic oil can penetrate andburn skin. Loosen hydraulicconnections very slowly to allowthe oil pressure to dissipategradually. Do not allow oil to squirtor spray.Electrocution/burn hazard. Contactwith electrically charged circuitscould result in death or seriousinjury. Remove all rings, watchesand other jewelry.Note: Be sure that the hydraulic oil level is withinthe top 2 inches / 5 cm of the sight gauge.Note: Perform this procedure with the machine ona firm, level surface.1 Disconnect all electrical tools from the machine.2 Start the engine from the platform controls.3 Press the generator select switch.Result: The generator should activate and theengine should go to high rpm.4 Connect an electrical tool, which does not drawmore than 15A, to the electrical outlet at theplatform controls and run the tool at full speed.5 Connect the positive and negative leads from amultimeter of sufficient capacity to the electricaloutlet at the generator.Result: The reading on the multimeter should be112 to 118V AC.Result: If the reading on the multimeter is not112 to 118V AC, proceed to step 6.6 Turn the key switch to the off position.7 Use a wrench to hold the generator flowregulator valve (item AM) and remove the cap.a generator manifoldb flow regulator8 Adjust the internal hex socket. Turn it clockwiseto increase the AC voltage or counterclockwiseto decrease the AC voltage. Install the flowregulator valve cap.Component damage hazard.Failure to adjust the generator asinstructed may result in damage tothe generator or other electricalequipment. Do not adjust thegenerator to other than specified.9 Repeat steps 2 through 5 to confirm thegenerator AC voltage.ANAMALba
