the engine is running, or immediately aer it is turned
off. Never operate the engine with heat shields or guards
removed.
Engine Speed

to increase the maximum engine speed.

engine warranty. The maximum allowable
high idle speed for these engines is 3675 RPM,
no load.
Refer to the operating instructions of the equipment
this engine powers. Because of equipment design or
application, there may be more stringent restrictions
regarding the angle of operation.
NOTE: Do not operate this engine continuously
at angles exceeding 25° in any direction.
Engine damage could result from insufficient
lubrication.
Cooling
NOTE: If debris builds up on the grass screen or other
cooling areas, stop the engine immediately
and clean. Operating the engine with blocked
or dirty air intake and cooling areas can cause
extensive damage due to overheating. See
Clean Air Intake/Cooling Area.
Check Oil Level
The importance of checking and maintaining
the proper oil level in the crankcase cannot be
overemphasized. Check oil BEFORE EACH USE as
follows:
1
Perform these maintenance procedures more frequently under extremely dusty, dirty conditions.
2
Have a Kohler Engine Service Dealer perform these services.
1. Make sure the engine is stopped, level, and is cool
so the oil has had time to drain into the sump.
2. Clean the area around and the underside of the
oil fill cap/dipstick before removing it. This will
help keep dirt, debris, and other foreign maer
out of the engine.
