Cold Weather Starting Hints

  1. Use proper oil for temperature expected.
  2. Disengage all possible external loads.
  3. Use fresh winter grade fuel. Winter grade fuel has higher volatility to improve starting.
  4. Make sure battery has a full charge.

Stopping

  1. If possible, remove load by disengaging all PTO driven attachments.
  2. Position throttle control between half and full throttle; stop engine.
  3. Do not allow engine/application to be left unattended with key ON (RUN position) for long periods. If left in such a condition, operator must turn key completely OFF before attempting a restart to reset system.

Angle of Operation

Refer to operating instructions of equipment this engine powers. Do not operate this engine exceeding maximum angle of operation; see specification table. Engine damage could result from insufficient lubrication.

Engine Speed

NOTE: Do not tamper with governor setting to increase maximum engine speed. Overspeed is hazardous and will void warranty.

High Altitude Operation

If this engine is operated at an altitude of 4000 ft. (1219 meters) or above, a high altitude carburetor kit is required. To obtain high altitude carburetor kit information or to find a Kohler authorized dealer, visit KohlerEngines.com or call 1-800-544-2444 (U.S. and Canada).
This engine should be operated in its original configuration below 4000 ft. (1219 meters).
Operating this engine with the wrong engine configuration at a given altitude may increase its emissions, decrease fuel efficiency and performance, and result in damage to the engine.
