Oil Recommendations
We recommend use of Kohler oils for best
performance. Other high-quality detergent
oils (including synthetic) of API (American
Petroleum Institute) service class SJ or higher
are acceptable. Select viscosity based on air
temperature at time of operation as shown in
table below.

Check Oil Level
NOTE:
To prevent extensive engine wear or
damage, never run engine with oil level below
or above operating range indicator on dipstick.
Ensure engine is cool. Clean oil
fi
ll/dipstick
areas of any debris.
1. Remove dipstick; wipe oil off.
2. Reinsert dipstick into tube; rest on oil
fi
ll
neck; turn counterclockwise until cap drops
down to lowest point of thread leads; do not
thread cap onto tube.
a. Remove dipstick; check oil level. Level
should be at top of indicator on dipstick.
or
b.
Remove
oil
fi
ll plug. Level should be up
to point of over
fl
owing
fi
ller neck.
3. If oil is low, add oil up to point of over
fl
owing
fi
ller neck.
4. Reinstall dipstick or oil
fi
ll plug and tighten
securely.
Change Oil
Change oil while engine is warm.
1. Clean area around oil
fi
ll cap/dipstick and
drain plug.
2. Remove drain plug and oil
fi
ll cap/dipstick.
Drain oil completely.
3. Reinstall drain plug. Torque to 13 ft. lb.
(17.6 N·m).
4. Fill crankcase with new oil, up to point of
over
fl
owing
fi
ller neck.
5. Reinstall oil
fi
ll cap/dipstick and tighten

Oil Sentry
™
(if equipped)
This switch is designed to prevent engine
from starting in a low oil or no oil condition. Oil
Sentry
™
may not shut down a running engine
before damage occurs. In some applications
this switch may activate a warning signal. Read
your equipment manuals for more information.
Reduction Systems (if equipped)
Some engines are equipped with a gear
reduction system. Follow maintenance and oil
change information speci
fi
ed in this section and
maintenance schedule.
2:1 Reduction System (CH270)
This reduction system is lubricated by engine
crankcase oil. No special maintenance or
service is necessary. Check and maintain
engine oil level as outlined in Check Oil Level.
2:1 with Clutch Reduction System (CH270,
CH395, CH440)
This reduction system uses a clutch assembly
and chain and sprocket drive system,
independent of, and separated from main
crankcase lubrication. Check and maintain oil
level using dipstick in gear box case. Change
reduction system oil at interval in maintenance
schedule. Use 20W-40 or 20W-50 oil in this
gear box case. Oil capacity of this gear box is
0.5 L (0.52 U.S. qt.).
1. Drain old oil out through oil drain plug of gear
box cover, tip engine as required. Reinstall
drain plug and tighten securely.
2. Engine must be level. Add new 20W-40 or
20W-50 oil through oil dipstick hole on top of
gear box case until oil level is up to bottom of
the mark on the oil dipstick in gear box case.
Reinstall dipstick securely into gear box
cover.
6:1 Reduction System (CH270)
This reduction system uses an internal pinion
and ring gear system, independent of, and
separated from main crankcase lubrication.
Check and maintain oil level using oil level/
drain plug hole in gear box case. Change
reduction system oil at interval in maintenance
schedule. Oil capacity of this gear box is 0.12 L
(0.13 U.S. qt.).
1. Drain old oil out through oil level/drain plug,
tip engine as required.
2. Engine must be level. Add new oil through oil
fi
ll plug hole on top until oil level is up to
bottom of oil level/drain plug hole. Reinstall
both plugs and tighten securely.
6:1 Reduction System (CH395, CH440)
This reduction system is lubricated by engine
crankcase oil. No special maintenance or
service is necessary. Check and maintain
engine oil level as outlined in Check Oil Level.
