Maintenance
Checking the Spark Plug
1. Inspect the spark plug
Note:
If you see light brown or gray on the
insulator, the engine is operating properly. A
black coating on the insulator usually means the
air cleaner is dirty.
Important:
Do Not clean the spark plug(s).
Always replace the spark plug(s) when it has:
a black coating, worn electrodes, an oily film,
or cracks.

Servicing a Kohler Engine
Servicing the Air Cleaner-Kohler
Engine
Service Interval: Every 50 hours—Clean the
air-cleaner paper element
(more often in dusty,
dirty conditions)(Kohler
engine).
Every 100 hours—Replace
the air-cleaner paper
element (more
often in dusty, dirty
conditions)(Kohler
engine).
Note:
Operating the engine with loose or damaged
air-cleaner components could allow unfiltered air into
the engine, causing premature wear and failure.
Removing the Elements:
1. Park machine on level ground, move the motion
control levers out to engage the parking brake,
disengage the blade control switch, stop engine,
and remove key. Wait for all moving parts to stop
before leaving the operator’s position.
2. Move the motion control levers out to engage
parking brake, stop the engine, remove the key,
and wait for all moving parts to stop before
leaving the operating position.
3. Clean around the air cleaner cover to prevent dirt
from getting into the engine and causing damage.
4. Rotate the latches outward.
