3. Before removing the oil filter, clean the surrounding
area to keep dirt and debris out of the engine.
Remove the old filter and wipe/clean the surface
where the filter mounts.
4. Reinstall the drain plug. Make sure it is tightened
to 13.6 N·m (10 ft. lb.).
5. Place a new oil filter in a shallow pan with the open
end up. Pour new oil, of the proper type, in through
the threaded center hole. Stop pouring when the oil
reaches the bottom of the threads. Allow a minute
or two for the oil to be absorbed by the filter
material.
6. Put a drop of oil on your fingertip and wipe it on the
rubber gasket.
7. Install the new oil filter to the filter adapter. Turn the
oil filter clockwise until the rubber gasket contacts
the surface, then tighten the filter an additional
2/3-1 turn.
8. Remove the oil fill cap from the valve cover. Fill the
crankcase with new oil, of the proper type, to the
"F" mark on the dipstick. Refer to "Oil Type" and
"Check Oil Level" on pages 6.1 and 6.2. Always
check the level with the dipstick before adding
more oil. Push dipstick in completely.
9. Reinstall the oil fill cap and tighten securely by
turning to the right.
NOTE: To prevent extensive engine wear or
damage, always maintain the proper oil
level in the crankcase. Never operate the
engine with the oil level below the ''L''
mark or above the ''F'' mark on the
dipstick.
Angle of Operation
This engine will operate continuously at angles up to
20°. Check oil level to assure crankcase oil level is at
the ''F'' mark on the dipstick.
Refer to the operating instructions of the equipment this
engine powers. Because of equipment design or
application, there may be more stringent restrictions
regarding the angle of operation.
NOTE: Do not operate this engine continuously at
angles exceeding 20° in any direction. Engine
damage could result from insufficient
lubrication.

Oil Sentry
Some engines are equipped with an optional Oil
Sentry ™
decreases below an acceptable level, the Oil Sentry
will either shut off the engine or activate a warning
signal, depending on the application.
Operation
The pressure switch is designed to break contact as
the oil pressure increases, and make contact as the oil
pressure decreases. At oil pressure above
approximately 3.0/5.0 psig, the switch contacts open.
Below this pressure, the switch contacts close.
On stationary or unattended applications (pumps,
generators, etc.), the pressure switch can be used to
ground the ignition module to stop the engine.
On vehicular applications (lawn tractors, mowers, etc.)
the pressure switch can only be used to activate a
warning light or signal.
NOTE: Make sure the oil level is checked BEFORE
Installation
