CLEANING YOUR GENERATOR
Keep the generator clean to prevent improper operation or machine damage from dirt and debris. Inspect all ven-
tilation openings on the generator. These openings must be kept clean and unobstructed.
If the generator becomes dirty, use a damp cloth to wipe exterior surfaces. Use a soft bristle brush to loosen dirt
and oil and use a vacuum to pick up loose dirt. Use low pressure air (not to exceed 25 PSI) to blow away dirt.
WARNING! Never clean the generator when it is running! Never clean with a bucket of water or a hose.
Water can get inside the working parts of the generator and cause corrosion or a short circuit.
CHECKING/ADDING OIL
Check the oil level before each use and every 8 hours of operation (refer to page 23, Table 4). The oil capacity
of the generator engine is 17.0 fl. oz. (0.5 L). Add oil when the oil level is low. For the proper type and weight of
oil refer to page 14, Fig. 7. This is a critical step for proper engine starting. The generator is equipped with a with
low-oil shut down to protect it from running without oil.
To check the oil level and/or add oil refer to "Step 1 - Add/Check Oil" on page 14.
TIP: Your WEN generator is compatible with the WEN 55201 Magnetic Oil Dipstick (not included), available for
purchase at wenproducts.com. The dipstick's industrial-strength magnetic tip will collect metal shavings from
your generator's oil tank to help preserve the engine and extend your generator's lifespan.
DRAINING/CHANGING OIL
Change the oil according to the Recommended Maintenance Schedule (refer to page 23, Table 4). Change
the oil more often if operating under heavy load or high ambient temperatures. It is also necessary to drain the oil
from the crankcase if it has become contaminated with water or dirt. Changing the oil when the engine is warm
allows for complete drainage.
1. Place generator on a level, elevated platform. Prepare
an approved oil-storage container underneath the oil drain
bolt next to the oil dipstick to catch the oil as it drains. See
Fig. 15. NOTE: To avoid possible fuel spills from the car-
buretor bowl, drain the carburetor (refer to "Draining The
Carburetor" on page 25) before draining the oil.
2. Unscrew the oil drain bolt and allow oil to drain from the
engine completely.
3. Reinstall the oil drain bolt and tighten it securely. Wipe
clean any oil spillage.
4. To add new oil, refer to "Step 1 - Add/Check Oil" on page
14.
NOTE: Never dispose of used engine oil in the trash or down a drain. Please call a local recycling center or auto
garage to arrange proper oil disposal.
