Clean Air Intake/Cooling Areas
To ensure proper cooling, make sure the grass screen,
cooling fins, and other external surfaces of the engine
are kept clean at all times.
Every 50 hours of operation (more often under
extremely dusty, dirty conditions), remove the blower
housing and other cooling shrouds. Clean the cooling
fins and external surfaces as necessary. Make sure
the cooling shrouds are reinstalled.
NOTE: Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or
cooling shrouds removed, will cause engine
damage due to overheating.
Check Spark Plug
Every 100 hours of operation, remove the spark plug,
check its condition, and reset the gap or replace with a
new plug as necessary. Use a Champion® type RH10
(or equivalent) spark plug.
1. Before removing the spark plug, clean the area
around the base of the plug to keep dirt and
debris out of the engine.
2. Remove the plug and check its condition.
Replace the plug if worn or reuse is questionable.
NOTE: Do not clean the spark plug in a machine
using abrasive grit. Some grit could
remain in the spark plug and enter the
engine causing extensive wear and
damage.
3. Check the gap using a wire feeler gauge. Adjust
the gap to 0.025 in. (0.65 mm) by carefully
bending the ground electrode. See Figure 8.
4. Reinstall the spark plug into the cylinder head.
Torque the spark plug to 18-22 ft. lb.
(24-30 N·m).

Battery Charging
WARNING: Explosive Gas!
Batteries produce explosive hydrogen gas while being
charged. To prevent a fire or explosion, charge
batteries only in well ventilated areas. Keep sparks,
open flames, and other sources of ignition away from
the battery at all times. Keep batteries out of the reach
of children. Remove all jewelry when servicing
batteries.
Before disconnecting the negative (–) ground cable,
make sure all switches are OFF. If ON, a spark will
occur at the ground cable terminal which could cause
an explosion if hydrogen gas or gasoline vapors are
present.
Fuel Filter
Some engines are equipped with an in-line fuel filter.
Periodically inspect the filter and replace when dirty.
Use a genuine Kohler filter.
