energized by the generator. Make sure the connections are
correct and are tight.
8. Make sure all loads are turned off. Do not start the genera-
tor under load.
GENERATOR STARTING PROCEDURE
1. With the power take-off drive disengaged, start the engine
which will drive the generator. Run the engine long enough to
warm it up before proceeding, so that it will run smoothly and
achieve full power under generator load.
2. With engine idling, engage the power take-off drive.
3. Watch the voltmeter on the generator and slowly increase
engine speed until the output reaches approximately 260 volts
(in green portion of voltmeter scale). For 208 volt generators
the output should reach 215 to 220 volts.
4. With engine and generator running smoothly, switch on the
electrical load while watching the voltmeter.
NOTE: Equipment Damage
If the load includes motors turn them on one at a time, highest
starting current motor first, next highest second, etc.
Readjust engine throttle to keep generator output under load
at 240V or 208 depending on the generator (in green portion
of voltmeter scale). If engine is equipped with speed governor,
it may automatically readjust the throttle as the load changes
and keep the generator output at the proper level. However,
some governors are not sensitive enough to maintain proper
output under changing load, and in such cases the throttle will
have to be manually readjusted .
GENERATOR SHUTDOWN PROCEDURE
1. Switch off electrical load.
2. Reduce speed of engine driving generator to idle.
3. Disengage power take-off drive, and allow generator to
coast to a stop.
WARNING: Personal Injury
Never try to manually stop the generator. Always let it coast
until it stops.
5. Shut off the engine.
4. Disconnect drive shaft (tumbling bar)
power take-off end first, then generator end.

3. Make sure the drive shaft (tumbling bar) is assembled with
its universal joint knuckles “synchronized,” as illustrated in
Figure 7. If knuckles are not synchronized, the bar will chatter
when rotating, which will cause the generator output voltage to
flicker.
DANGER: Personal Injury
POWER TAKE-OFF MUST BE DISENGAGED AT THIS TIME.
4. Couple the tractor to the generator with the drive shaft
(tumbling bar). Couple the tumbling bar to the generator input
shaft first, then to the power take-off shaft. Check alignment,
tractor, power take-off shaft (tumbling bar), and generator input
shaft should form a straight (or nearly straight) line, with less
than 15° misalignment between the shafts. Misalignment will
cause generator output voltage to flicker.
CAUTION:
Make sure that all tumbling bar lock pins are engaged and
that all safety shields are in place before operating the PTO
generator.
5. Make sure no binding exists in generator or gear box. If
binding is found, locate the cause and correct it before
proceeding.
6. Make sure that the electrical loads to be driven by the
generator will not draw more current than the ratings of the
generator receptacle or cord set which will supply the current.
7. Check all electrical connections in the system to be
