GENERATOR PREPARATION
The following section describes the necessary steps to prepare the generator for use. If you are unsure about how to
perform any of the steps please call 1-847-429-9263 (M-F 8-5 CST) for customer service. Failure to perform these
steps properly can damage the generator or shorten its life.
STEP 1 - ADD/CHECK 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’s crankcase is 20.3 fl. oz. (0.6 L).
CAUTION! Keep the generator level. Tilting the generator
to assist in filling will cause oil to flow into the wrong
areas of the engine and cause damage.
TO ADD OIL:
1. Place the generator on a level surface. Make sure the en-
gine is OFF before adding or checking oil.
2. Unscrew the oil dipstick (Fig. 3) from the engine.
3. Using an oil funnel or appropriate dispenser, slowly add
oil into the oil fill, being careful not to overfill the unit. Fill the
crankcase to the upper fill line so you can visually see the oil
coming halfway up the oil fill threads. See Fig. 4.
4. Reinstall the oil dipstick and firmly tighten it. Wipe clean
any spilled oil.
NOTE: Extend the lifespan of your generator by catching the
loose metal filaments that naturally build up inside the crank
case with the WEN Magnetic Dipstick (Model 55201) , avail-
able for purchase at wenproducts.com.
