BEFORE CONTINUING, VERIFY THAT ALL HOSE CLAMPS ARE TIGHT.
4. Fill the crankcase to the proper oil level. With the engine running and warm, loosen the mounting bracket
adjustment bolts and adjust the LM2000 so that the oil level in the sight gauge is aligned with the white “index
line” on the dial (Figure 5). Tighten the adjustment bolts securely.
Connecting the LM2000 to an Oil Supply Tank
1. Remove the plug from the oil inlet connection. Be sure the removable
screen, inside the connection, is clear of debris. Install the oil inlet con-
nection.
2. Connect a 1/2 inch I.D. (13 mm) or larger hose to the oil inlet fitting on
the LM2000 and to the shutoff valve on the oil supply tank. See Figure
5. Recommended minimum height above the LM2000 is 2 ft. (0.6m);
maximum 25 ft. (7.7m). The hose must maintain a downward slope
and not have low spots or droops. Maximum head pressure rating is
9.50 psi or 25 ft oil (head pressure).
3. Before filling the supply tank with oil, be sure the tank is clean and dry
and the shutoff valve is closed. Also, be sure all hoses and clamps are
tight. Fill the tank with CLEAN oil.
4. After oil supply tank is full, open the shutoff valve.
Next, make the proper electrical connections for the application. (See Snap-switch ratings and schematic
on page 1.)
Switch Test
To test the shutdown or alarm functions perform the following:
1. Unscrew the vent fittings.
2. Using a long narrow shank screw driver, gently insert until contact is felt with float arm. Gently push the float
arm down.
3. Verify proper switch operation
WARNING: Overfill condition can be caused
by excessive inlet pressure and/or improper
“vent to crankcase” installation.
NOTE:
Installations with closed vent systems can only be tested with the engine off.
