Clean Air Intake/Cooling Areas
To ensure proper cooling, make sure the fl ywheel
screen, cooling fi ns, and other external surfaces of the
engine are kept clean at all times.
Every 100 hours of operation (more oft en under
extremely dusty, dirty conditions), remove the blower
housing and other cooling shrouds. Clean the cooling
fi ns and external surfaces as necessary. Make sure the
cooling shrouds are reinstalled.
NOTE: Operating the engine with a blocked
fl ywheel screen, dirty or plugged cooling
fi ns, and/or cooling shrouds removed, will
cause engine damage due to overheating.
Ignition System
CH640 and CH730 engines are equipped with an
electronic CDI system. CH740 engines are equipped
with an electronic DSAI system. Other than
periodically checking/replacing the spark plugs, no
maintenance, timing, or adjustments are necessary or
possible with these systems.
NOTE: Engines with a DSAI system will have leads
located near the fuel regulator. Connect the
leads for NG and leave disconnected for
LPG.
In the event starting problems should occur which are
not corrected by replacing the spark plugs, see your
Kohler Engine Service Dealer for trouble analysis.
Check Spark Plugs
Every 100 hours of operation, remove the spark plugs,
check condition, and reset the gap or replace with
new plugs as necessary. Every 300 hours or annually
replace the spark plugs. Refer to the chart below for
replacement spark plugs. Equivalent alternate brand
plugs can also be used.
