The Kohler® Advantage
• High Quality Power
Kohler home generators provide advanced voltage and
frequency regulation along with ultra -low levels of
harmonic distortion for excellent generator power quality to
protect your valuable electronics.
• Extraordinary Reliability
Kohler is known for extraordinary reliability and
performance and backs that up with a premium 5-year or
2000 hour limited warranty.
• Powerful Performance
Exclusive Powerboost- technology provides excellent
starting power.

The bold new Kohler design is completely corrosion proof,
even in harsh seaside environments, and is impact -
resistant even at -34° C (-30' F).
• Fast Response
Kohler generators restore power to your home quickly and
reliably.
o Digital voltage regulation protects your sensitive
electronics from harmonic distortion and unstable power
quality...
• Kohler Command PRO Engine Features
o Kohler Command PROD OHV engine with hydraulic valve
lifters for reliable performance without routine valve
adjustment or lengthy break-in requirements.
o Powerful, reliable air-cooled performance.
o Simple field conversion between natural gas and LPG
fuels while maintaining emission certification.
• Designed for Easy Installation
o Polymer base eliminates the need for a concrete
mounting pad, reducing installation time and cost.
o Fuel and electrical connections through the enclosure wall
eliminate the need for stub -ups through the bottom.
o Load connection terminal block allows easy field wiring.
o Designed for outdoor installation only.
• Certifications
o Meets emission regulations for U.S. Environmental
Protection Agency (EPA) with both natural gas and LPG.
Note: CARB does not regulate emergency standby
generators with outputs less than 50 HP.
o UL 2200/cUL listed (60 Hz model).
o CSA certification available (60 Hz model).
o GOST certified (Russia).
o Accepted by the Massachusetts Board of Registration of
Plumbers and Gas Fitters
• Approved for stationary standby applications in locations
served by a reliable utility source.
• Warranty
o 5-year/2000 hour limited warranty for on -grid (standby)
applications in locations served by a reliable utility source.
