Voltage Regulator Adjustment; Generator Rotor Bearing; Major Repairs; How To Order Parts - Generac Power Systems GR-210 Operation And Maintenance Manual

WARNING! Do not adjust the engine governed
speed without proper equipment and know-
how. The governed speed was factory set and
should require no additional adjustment.
Excessively high speeds are dangerous and
increase the risk of personal injury or damage to
equipment and/or property. Correct AC frequen-
cy and voltage are supplied only at the correct
governed speed. Some connected electrical
devices are extremely sensitive to frequency and
voltage, and may be damaged by incorrect fre-
quency and/or voltage. Operation of the unit at
excessively low speeds imposes a heavy load on
the engine when sufficient engine power is not
available and may shorten engine life.
Generally, if AC frequency and voltage are both
correspondingly high or low, the engine governor
requires adjustment. If AC frequency is correct but
voltage is not, the voltage regulator requires
adjustment or some other problem exists.

VOLTAGE REGULATOR ADJUSTMENT

The generator's AC voltage regulator has been factory
set to allow an operator to select proper voltage via the
voltage adjust dial. If the voltage regulator on the gener-
ator needs adjusting, contact an authorized service
facility. Only qualified service technicians should adjust
voltage regulators.

GENERATOR ROTOR BEARING

The generator rotor is attached to the engine drive shaft
at one end. The opposite end of the rotor rides in a pre-
lubricated and sealed ball bearing that requires no
additional lubrication for the life of the bearing.

NOTE:

MAJOR REPAIRS

Proper and regular maintenance of the generator is
needed to make sure the generator has a long and trou-
ble-free life. Only a qualified, competent authorized
Generac service technician should perform all major
generator service, including installation and replace-
ment of factory approved repair parts. Only qualified,
competent diesel engine repair facilities should service
the engine, using only factory approved parts.
