1.4 Generator Set Specifications
See Figure 1-2 for generator set specifications. Consult
the generator set nameplate for specific generator set
ratings.
1.5 Engine
The 8.5/11RMY generator sets are equipped with
four-cycle, twin cylinder, air-cooled Kohler engines.
Some of the engine features include:
D One-side serviceability of air cleaner, carburetor, oil
fill, dipstick, and oil drain.
D Efficient overhead valve design and full pressure
lubrication for maximum power, torque, and reliability
under all operating conditions.
D Electronic governor to ensure AC power output is
maintained at desired frequency.
D Overspeed shutdown to prevent governed frequency
from exceeding 70 Hz.
D Low oil pressure cutout to prevent failure.
D Dependable, maintenance free electronic ignition.
D Parts subject to the most wear and tear made from
precision formulated cast iron.
D Hydraulic valve adjusters to eliminate the need for
valve adjustments.
D Multi-fuel models with field-convertible fuel systems
that allow fuel changeover from natural gas to LP
vapor (and vice-versa) while maintaining CARB
certification. (This applies only to models with
specification numbers starting with the letters GM.)
See Figure 1-3 for engine specifications.

RATINGS: Standby ratings are continuous for the duration of any power outage. No overload capacity is specified at this rating. All single-phase units are rated at 1.0 power factor. DERA-
TION: Maximum altitude before generator deration, ft. (m): 1000 (305). Altitude deration factor, % per 1000 ft. (305 m): 3.0. Maximum intake air temperature before generator deration, _F
(_C): 60 (16). Temperature deration factor, % per 10_F(5.5_C): 2.0. Standard reference conditions are 25_C(77_F) and 100 kPa (29.5 in. Hg) total barometric pressure per ISO 85-28-1.
GENERAL GUIDELINES FOR DERATING: Maximum altitude before generator deration, ft. (m): 1000 (305). Altitude deration factor, % per 1000 ft. (305 m): 3.0. Maximum intake air
temperature before generator deration, _F(_C): 60 (16). Temperature deration factor, % per 10_F(5.5_C): 2.0.DERATING: ALTITUDE: Derate 4% per 305 m (1000 ft.) elevation above 153 m
(500 ft.). TEMPERATURE: Derate 1% per 5.5_C(10_F) temperature increase above 25_C(77_F). Derate applies to actual conditions at the carburetor inlet. Availability is subject to change
without notice. Kohler Co. reserves the right to change the design or specifications without notice and without any obligation or liability whatsoever. Contact your local Kohler Co. generator
