How to Change the Oil

Follow these steps to perform an oil change on your generator:

Before You Begin

Make sure the generator is turned off, has cooled down, and is placed on a level surface before starting.

Caution: Worn out or dirty oil can prevent proper cooling and may cause serious engine damage.

Step 1: Remove the Drain Plug

Using a 12 mm hex wrench, loosen and remove the oil drain plug.

The drain plug is located on the crankcase, underneath the oil filler/dipstick cap.

Step 2: Drain the Oil

Allow all of the old oil to drain completely from the generator into an approved oil disposal container.

Dispose of used oil properly according to local regulations. A local auto parts store may provide disposal guidance.

Step 3: Reinstall the Drain Plug

Once the oil has fully drained, reinstall the oil drain plug.

Tighten it securely using a 12 mm hex wrench.

Step 4: Refill with New Oil

Remove the oil filler/dipstick cap and add the correct type and amount of new oil for your generator model.

Fill carefully and avoid overfilling.

Step 5: Check the Oil Level

Use the dipstick to confirm the oil level is within the recommended range.

Add more oil if needed.

Step 6: Secure the Oil Cap and Inspect

Reinstall the oil filler/dipstick cap securely.

Start the generator briefly and check for any leaks around the drain plug.

Important Notes

• Change the oil at the intervals recommended in your owner’s manual.

• If the oil appears contaminated with water or dirt, drain it immediately.

• Always use the oil type recommended for your specific generator model.
