PREPARING THE GENERATOR FOR USE 

 

Using this Generator for the First-Time 

 

STOP!        

 

The following section describes the required steps for preparing this generator for the first use. Failure to correctly perform these steps 
can damage this generator and/or shorten its life. If still unsure about how to perform any of these steps after reading this section, call  
1-866-460-9436 Monday - Friday, 8 AM - 4 PM Central Time for customer service. 

 
If this generator is being used for the first time, the following few steps are required to prepare it for operation: 
 

Step 1 - Add Oil 

 

This generator requires engine oil to function. Engine oil is a major factor affecting engine performance and service life.

 When new from 

the package, this generator contains no oil in the engine crankcase. The correct quantity of oil is equal to the oil capacity of the engine crankcase 
and is 38 fluid oz. Add the correct quantity of oil before operating this generator for the first time. When replenishing oil for subsequent use of this 

generator, always determine that this generator has the correct quantity of oil. 
 

ITEM # GEN7500TRI Oil Capacity 

38 ounces 

ITEM # GEN7500TRI Oil Type Recommended 

High Detergent Motor Oil, SAE10W-30 

 
To add oil: 
1. Confirm that this generator is on a level surface. 

2. Unscrew the oil filler/dipstick cap from the engine as illustrated in Figure 1. 

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, all-

temperature use. 

When the engine crankcase is full, the oil level should reach all the way up to the threads

 as illustrated in Figure 2. 

4. Replace the oil filler/dipstick cap.
