operating range indicator on dipstick.
Ensure engine is cool. Clean oil fill/dipstick areas of any
debris.
1. Remove dipstick; wipe oil off.
2. Reinsert dipstick into tube; press completely down.
3. Remove dipstick; check oil level. Level should be at
top of indicator on dipstick.
4. If oil is low on indicator, add oil up to top of indicator
mark.
5. Reinstall and secure dipstick.
CHANGE OIL AND FILTER
Change oil while engine is warm.
1. Clean area around oil fill cap/dipstick and drain plug.
Remove drain plug and oil fill cap/dipstick. Allow oil
to drain completely.
2. Clean area around oil filter; remove filter; wipe off
mounting surface. Reinstall drain plug and torque to
21.4 N·m (16 ft. lb.).
3. Place new filter in shallow pan with open end up. Fill
with new oil until oil reaches bottom of threads. Allow
2 minutes for oil to be absorbed by filter material.
4. Apply a thin film of clean oil to rubber gasket on new
filter.
5. Refer to instructions on oil filter for proper
installation.
6. Fill crankcase with new oil. Level should be at top of
indicator on dipstick.

OIL SENTRY
This switch is designed to prevent engine from starting
in a low oil or no oil condition. Oil Sentry
down a running engine before damage occurs. In some
applications this switch may activate a warning signal.
Read your equipment manuals for more information.
Oil Sentry pressure switch is installed in closure plate
™
pressure port. On engines not equipped with Oil Sentry
installation hole is sealed with a 1/8-27 N.P.T.F. pipe
plug.
Installation
1. Apply pipe sealant with Teflon
Thread Sealant or equivalent) to threads of switch.
2. Install switch into tapped hole in closure plate.
3. Torque switch to 10.7 N·m (95 in. lb.).
Testing
Compressed air, a pressure regulator, pressure gauge,
and a continuity tester are required to test switch.
1. Connect continuity tester across blade terminal and
metal case of switch. With 0 psi pressure applied to
switch, tester should indicate continuity (switch
closed).
2. Gradually increase pressure to switch. As pressure
increases through range of 7-11 psi tester should
indicate a change to no continuity (switch open).
Switch should remain open as pressure is increased
to 90 psi maximum.
3. Gradually decrease pressure through range of 7-11
psi. Tester should indicate a change to continuity
(switch closed) down to 0 psi.
4. Replace switch if it does not operate as specified.
