Oil Pressure Switch

The optional low oil pressure switch is located on the sump or oil filter adapter (A, Figure 25).

The switch should open at approximately 4-5 PSI (.27-.34 bar) for Model Series 28N700, 28P700, 287700, 310700, 312700, 313700, 330700.

Model Series 28N777 Type 1194-E1 opens at approximately 9-13 PSI (.62 -.90 bar).

Oil Gard Systems

Horizontal Model Series 110000, 120000, 150000, 200000, 210000

The Oil Gard System consists of:

•Oil Sensor (A, Figure 26 and Figure 27) (located inside crankcase)

•Module (B)

•Three-terminal stop switch (C)

•Connecting wires

If the oil level is low, the Oil Gard sensor will close. The engine cannot be restarted until sufficient oil is added. If equipped with a lighted rocker switch, the light will flash when the starter is actuated, indicating insufficient oil in the crankcase.
