Subsequent Use of this Generator

For subsequent uses of this generator after the first use, certain steps still must be completed to prepare it for operation.

IMPORTANT: Be familiar with the procedures described in the previous section titled “Using the Generator for the First Time” of this manual. If not, review this section now.

Step 1 - Verify Oil Level

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

1.Verify that this generator is 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.Fully insert the dipstick without screwing the filler/dipstick 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. (See “Changing/Adding Oil” in the “Maintenance/Care” section of this manual).

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

Step 2 - Verify Gas Level

Before starting this generator, verify that there is sufficient gasoline in the fuel tank. The fuel gauge, located on the top of this generator, indicates the gas level currently in the fuel tank. If necessary, add fresh unleaded gasoline with an octane rating of 87 or higher according to “Step 2 - Add Gasoline” of the “Using this Generator for the First Time” section of this manual.

Model GEN1850 Fuel Tank Capacity (gals /L)	2.3/8.9
Model GEN1850 Fuel Type	Fresh, Unleaded Gasoline Octane Rating 87 or Higher

Gasoline and gasoline fumes are highly flammable and explosive. Handling fuel can result in serious injury or burns.

•Do not fill the fuel tank near a heat, sparks or an open flame. Keep gasoline away from appliance pilot lights, barbecues, electric appliances, power tools, etc.

•Always allow several minutes for the engine to cool before refueling.

•Do not overfill the fuel tank. Always check for fuel spills and immediately wipe them up. Spilled fuel is a fire hazard and causes environmental damage.

IMPORTANT:

•Use only fresh UNLEADED gasoline with an octane rating of 87 or higher.

•Never use old and/or contaminated gasoline.

•Never use a mixture of oil and gasoline.

•Avoid getting dirt and/or water in the fuel tank.

•Never store generator for extended time with gasoline in the fuel tank.

Step 3 - Ground the Generator

Failure to properly ground this generator can result in electrocution.

Ground this generator by tightening the grounding nut against a grounding wire. A generally acceptable grounding wire is a No. 12 AWG (American Wire Gauge) stranded copper wire. The other end of this grounding wire should be connected to a copper or brass grounding rod that is driven into the earth.

Grounding codes can vary by location. Contact a local electrician for information on grounding regulations for your area.
