Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF, SG,
SH, SJ or higher. DO NOT use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W30 may cause increased oil
consumption. Check oil level more frequently.
NOTICE
Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with
“SJ/CF ENERGY CONSERVING” or higher, is an
acceptable oil at all temperatures. Use of synthetic
oil does not alter required oil change intervals.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 8 hours of operation. Keep oil level maintained.
1. Make sure generator is on a level surface.
2. Clean area around oil fill and remove oil fill cap.
3. Verify oil is at the point of overflowing at oil fill opening.
4. Replace and tighten oil fill cap.
Adding Engine Oil
1. Make sure generator is on a level surface.
2. Check oil level as described in
Checking Oil Level
.
3. If needed, slowly pour oil into oil fill opening to the
point of overflowing at oil fill.
4. Replace and tighten oil fill cap.
Changing Engine Oil
If you are using your generator under extremely dirty or
dusty conditions, or in extremely hot weather, change the oil
more often.
KEEP OUT OF REACH OF CHILDREN. DON’T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.
Change the oil while the engine is still warm from running,
as follows:
1. Make sure unit is on a level surface.
2. Disconnect the spark plug wire from the spark plug and
place the wire where it cannot contact spark plug.
3. Clean area around oil drain plug (
A
). The oil drain plug
is located at base of engine, opposite carburetor.
4. Remove oil drain plug and drain oil completely into a
suitable container.
5. Reinstall oil drain plug and tighten securely. Remove oil
fill cap.
6. Slowly pour oil (about 20 oz.) into oil fill opening (
