Engine Oil Change - Westinghouse WGen9500DFc User Manual

1. Remove the foam air filter and wash it by submerging
the element in a solution of household detergent soap
and warm water. Slowly squeeze the foam to thoroughly
clean.
DO NOT twist or tear the foam air filter element during
cleaning or drying. Only apply slow but firm squeezing
action.
2. Rinse the air filter element by submerging it in fresh
water and applying a slow squeezing action. Allow the
filter to dry thoroughly.
DO NOT pollute. Follow the guidelines of the EPA or other
governmental agencies for proper disposal of hazardous
materials. Consult local authorities or reclamation facility.
3. Dip the foam air filter in clean engine oil then squeeze
out all excess oil. The engine will smoke when started if
too much oil is left in the filter.
4. Install the foam air filter in the housing, then the coarse
air filter. Install the air cleaner cover and secure with the
cover clips.
ENGINE OIL LEVEL CHECK
Avoid skin contact with engine oil. Wear protective
clothing and equipment. Wash all exposed skin with
soap and water.
ALWAYS use the specified engine oil. Failure to use the
specified engine oil can cause accelerated wear and/or
shorten the life of the engine.
When using the generator under extreme, dirty, dusty
conditions or in extremely hot weather, change the oil
more frequently.
Ambient air temperature will affect engine oil performance.
Change the type of engine oil used based on weather
conditions.

MAINTENANCE
Check the engine oil level before each use or every 8
hours of operation.
1. Place the generator on a level surface and allow the
engine to cool for several minutes.
2. With a damp rag, clean around the oil dipstick.
3. Remove the oil dipstick and wipe the dipstick clean.
4. Wipe the dipstick clean, then insert it into the oil filler
neck without screwing it in. Remove the dipstick and
verify that the oil level is within safe operating range
between the low (L) and high (H) marks on the dipstick.
5. If low, add recommended engine oil incrementally and
recheck until the level is between the L and H marks on
the dipstick. DO NOT overfill. If over the full mark on
the dipstick, drain the oil to reduce the oil level to the
full mark.
6. Replace the oil dipstick and hand-tighten.
