MAINTENANCE

AIR FILTER MAINTENANCE

Routine maintenance of the air filter helps maintain proper airflow 

to the carburetor. Occasionally check that the air filter is free of ex-

cessive dirt. The air filter should be checked every 50 hours of use. 

Refer to Recommended Maintenance Schedule in Table 4.

1. Remove the oil access panel. Unscrew the four Phillips-head 

screws and remove the side panel (Fig. 23 - 1).

2. Open the air filter cover (Fig. 24 - 1), and remove the foam air 

filter element from the casing. 

3. Check and clean the foam air filter element. Wash the filter ele-

ment in warm soapy water. Squeeze it thoroughly dry in a clean 

cloth. Saturate the element in clean engine oil and squeeze off ex-

cess oil in a clean absorbent cloth. A small amount of oil in the 

element is normal and necessary for the engine to work properly. 

If the element is damaged, replace it with a new one 

(part. no. 

56202i-163, available at wenproducts.com).

4. Reinstall the air filter element and close the air filter cover. Close 

the air filter cover. Replace the side cover and secure it with the 

screws. Reinstall the oil access panel.

CAUTION!

 Running the engine with a dirty, damaged, or missing air filter element will result in possible 

danger and cause the engine to wear out prematurely.

DRAINING THE CARBURETOR

Drain the carburetor after every use and before storing

the generator 

(refer to Table 4). 

Draining the

carburetor can help prevent build-up and blockages caused

by stagnant fuel inside of the carburetor.
1. Prepare an approved gasoline storage container.
2. Remove the oil access panel. Unscrew the four Phillips-head 

screws and remove the side panel (Fig. 23 - 1).
3. Open up the carburetor drain screw (Fig. 25) with a Phillips 

screwdriver and drain out any gasoline that has built up inside the 

carburetor. 
4. Once the fuel has drained, tighten the drain screw with the 

screwdriver. 

NOTE:

 Make sure to drain your carburetor before storing the gen-

erator for long periods of time.
5. Replace the side panel and secure it with the screws. Reinstall 

the oil access panel.
