Checking the Oil Level

It is important to check the oil level in the engine crankcase before each use to ensure that there is a sufficient quantity.

To check the oil level:

1.Verify that this generator is shut down and on a level surface.

2.Unscrew the oil filler/dipstick cap from the engine.

3.With a dry cloth, wipe the oil off of the dipstick that is located on the inside of the cap.

4.Insert the dipstick as if replacing the cap and then remove again. There should be oil on the dipstick. If there is no oil on the dipstick, or oil is visible only at the very end of the dipstick, add oil until the engine crankcase is filled.

5.Confirm that the oil filler/dipstick cap is properly in place when finished verifying the oil level.

Changing/Adding Oil

The oil level in this generator should be checked before each use. (See Figure 9.) When the oil level is low, add oil until the level is sufficient to operate this generator.

The oil capacity for this Model GEN154 2000 Surge Watts / 1500 Running Watts Portable Generator engine is 13.5 fluid oz. (0.40 L).

To drain the oil from this generator:

It is necessary to drain the oil from the crankcase only if it has become contaminated with water and/or dirt.

1.Place a bucket underneath this generator to catch oil as it drains.

2.Unscrew the oil drain plug located on the crankcase underneath the oil filler/dipstick cap.

3.Allow all the oil to drain from this generator.

4.Replace the oil drain plug and tighten.

NOTE: Never dispose of used motor oil in the trash, down a drain or on the ground. Put oil in a sealed container and contact your local recycling center or auto garage to arrange oil disposal.

To add oil to the engine crankcase:

1.Confirm that this generator is on a level surface.

2.Unscrew the oil filler/dipstick cap from the engine as illustrated in Figure 8 below.

3.Using a funnel, add high detergent motor oil to fill the engine crankcase to the correct quantity. SAE10W-30 oil is recommended for general use. When the engine crankcase is full, the oil level should reach the lower lip of the oil filling opening as shown in Figure 8.
