Kohler Courage SV710-740 Service Manual page 56

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 low
oil warning light or signal.
NOTE: Make sure the oil level is checked before each
use, and is maintained up to the "FULL"
or "F" mark on the dipstick. This includes
engines equipped with Oil Sentry™.
The pressure switch on Oil Sentry™ equipped models
is mounted to the oil filter or oil cooler adapter. See
Figure 6-9.
To install the switch, follow these steps:
1. Apply pipe sealant with Teflon
59241 or equivalent) to the threads of the switch.
2. Install the switch into the tapped hole in the
adapter. See Figure 6-9.
3. Torque the switch to 4.5 N·m (40 in. lb.).
Compressed air, a pressure regulator, pressure gauge
and a continuity tester are required to test the switch.
1. Connect the continuity tester across the blade
terminal and the metal case of the switch. With
0 psi pressure applied to the switch, the tester
should indicate continuity (switch closed).
2. Gradually increase the pressure to the switch. As
pressure increases through the range of
3.0/5.0 psi, the tester should indicate a change to
no continuity (switch open). The switch should
remain open as the pressure is increased to 90 psi
maximum.
3. Gradually decrease the pressure through the
range of 3.0/5.0 psi. The tester should indicate a
change to continuity (switch closed) down to
0 psi.
4. Replace the switch if it does not operate as
specified.
