WARNING: Hot Parts!
Engine components can get extremely hot from
operation. To prevent severe burns, do not touch these
areas while the engine is running–or immediately after it
is turned off. Never operate the engine with heat shields
or guards removed.
Maintenance, repair, or replacement of the emission control devices and systems, which are being done
at the customers expense, may be performed by any non-road engine repair establishment or individual.
Warranty repairs must be performed by an authorized Kohler service outlet.
WARNING: Accidental Starts!
Disabling engine. Accidental starting can cause severe injury or death. Before working on the engine or
equipment, disable the engine as follows: 1) Disconnect the spark plug lead(s). 2) Disconnect negative (-) battery
cable from battery.

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. Make sure the engine is stopped, level, and is cool
so the oil has had time to drain into the sump.
2. To keep dirt, debris, etc., out of the engine, clean
the area around the dipstick before removing it.
