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 and level. 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.
For CH260/CH270 engines, oil level
should be at middle of indicator on
dipstick.
For all other models, oil level should be
at top of indicator on dipstick.
or
b. Remove oil fi ll plug.
For CH260/CH270 engines, oil level
should be to middle of fi ller neck threads.
For all other models, oil level should be
up to point of overfl owing fi ller neck.
3. If oil is low, add oil to specifi ed level on
dipstick or fi ller neck threads for engine being
serviced. See step 2.
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 to specifi ed level
on dipstick or fi ller neck threads for engine
being serviced. See Check Oil Level.
5. Reinstall oil fi ll cap/dipstick and tighten
securely.
6. Dispose of used oil in accordance with local

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 specifi 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 (CH245,
CH255, CH270, CH395, CH440)
NOTE: Engines with this reduction system
must be operated at 2400 RPM or
higher under load, when full gear box
engagement occurs. Operating engine
under heavy loads below 2400 RPM,
could result in clutch/gear box failure
from disc slippage/overheating and
insuffi cient engine cooling, not covered
under normal warranty.
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.
