GENERATOR PREPARATION
Using the Generator for the First Time
The following section describes steps necessary to prepare the generator for use. If after
reading this section, you are unsure about how to perform any of the steps please call (888)
315-3080 M-F 8-5 CST for customer service. Failure to perform these steps properly can
damage the generator or shorten its life.
Step 1 - Fill Oil
The generator is shipped without oil. User must add the proper amount of oil before operating the
generator for the first time. The oil capacity of the engine crankcase is 37 fluid oz.
Select good quality detergent oil bearing the American Petroleum Institute (API) service
classifications SJ, SL, or SM. (Synthetic oils may be used.) Use the SAE viscosity grade
of oil from the following chart that matches the starting temperature anticipated before
the next oil changes.
Figure 7- Engine oil recommendations
To fill oil to the crankcase, follow these steps:
1. Make sure the generator is on a level surface. Tilting the generator to assist in filling will
cause oil to flow into engine areas and will cause damage. Keep generator level!
2. Remove the oil filler/dipstick cap from the engine as shown in figure 8.
3. Using a funnel, add the appropriate type and amount of oil into the crankcase. The
crankcase is full when the oil level has reached the second thread from the lip of the
opening (see figure 9).
4. Check for oil leaks. Reinstall oil filler cap before starting engine.
