How to Adjust the Generator
Voltage
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to squirt
or spray.
Electrocution/burn hazard. Contact
with electrically charged circuits
could result in death or serious
injury. Remove all rings, watches
and other jewelry.
Note: Be sure that the hydraulic oil level is within
the top 2 inches / 5 cm of the sight gauge.
Note: Perform this procedure with the machine on
a 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 the
engine should go to high rpm.
4 Connect an electrical tool, which does not draw
more than 15A, to the electrical outlet at the
platform controls and run the tool at full speed.
Part No. 72863
5 Connect the positive and negative leads from a
multimeter of sufficient capacity to the electrical
outlet at the generator.
Result: The reading on the multimeter should be
112 to 118V AC.
Result: If the reading on the multimeter is not
112 to 118V AC, proceed to step 6.
6 Turn the key switch to the off position.
7 Use a wrench to hold the generator flow
regulator valve (item AM) and remove the cap.

8 Adjust the internal hex socket. Turn it clockwise
to increase the AC voltage or counterclockwise
to decrease the AC voltage. Install the flow
regulator valve cap.
9 Repeat steps 2 through 5 to confirm the
generator AC voltage.
