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 4°C (40°F) the use of SAE 30 will result in hard starting.
** Above 27°C (80°F) the use of 10W30 may cause increased oil consumption.
Check oil level more frequently.
Checking Oil Level
Figure

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 (
4, H
), remove oil cap/dipstick and wipe
dipstick with clean cloth. Replace dipstick. Remove and and check oil
level.
NOTICE
DO NOT screw in dipstick when checking oil level.
3. Verify oil is at full mark (
7, A
) on dipstick. Replace and tighten oil cap/
dipstick.
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 full mark on dipstick.
DO NOT overfill.
NOTICE
Overfilling with oil could cause the engine to not start, or hard
starting.
• DO NOT overfill.
• If over the full mark on dipstick, drain oil to reduce oil level to full mark on
dipstick.
4. Replace and tighten oil cap/dipstick.
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 (
4, J
). 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/dipstick.
6. Repeat steps 3 and 4 to add engine oil as described in
Adding Engine
Oil
.
7. Wipe up any spilled oil.

Your engine will not run properly and may be damaged if you run it with a dirty
air cleaner. Service more often if operating under dirty or dusty conditions.
To service the air cleaner, follow these steps:
1. Loosen screws (
A
) and remove air cleaner cover (
B
).
2. Carefully remove cartridge (
