Generator Preparation - Wen DF1100 Manual

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 (800) 232-1195 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 crankcase is 37.2 fl. oz (1.1 L).
ENGINE OIL RECOMMENDATIONS -
leum Institute (API) service classifications SJ, SL, or SM (synthetic oils may be used). Select the SAE
viscosity grade of oil that matches the expected operating temperature. For general use (above 40° F),
we recommend 30W engine oil.
°F -20 0
°C -30 -20
To add oil, follow these steps:
1. Place the generator on a level surface. Make sure the engine
is OFF before adding or checking oil.
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.
2. Unscrew the oil dipstick from the engine.
3. Using an oil funnel or appropriate dispenser, slowly add oil
into the oil fill (Fig. 2), 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 (Fig. 3).
4. Reinstall the oil dipstick and firmly tighten it. Wipe clean any
spilled oil.
