Engine Maintenance
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. Engines on most
outdoor power equipment operate well with 5W30 Synthetic
oil. For equipment operated in hot temperatures, Vanguard®
15W50 Synthetic oil provides the best protection.
* 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.
Checking/Adding Engine Oil
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. Loosen the three maintenance cover screws and
remove the side maintenance cover.
3. Clean area around oil fill, remove dipsitck and wipe
with clean cloth. Replace dipstick. Remove and check
oil level.
4. Verify oil is at full mark (top hole) on dipstick.
5. If needed, using oil funnel, slowly pour oil into oil fill
opening to full mark (top hole) 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 (top hole) on dipstick, drain oil to
reduce oil level to full mark on dipstick.
6. Replace and tighten dipstick.
7. Replace the side maintenance cover and hand tighten
the three maintenance cover screws.
NOTICE Do not attempt to crank or start engine before
it has been properly serviced with recommended oil. This
could result in an engine failure.
CAUTION Avoid prolonged or repeated skin contact
with used motor oil. Used motor oil has been shown
to cause skin cancer in certain laboratory animals.
Thoroughly wash exposed areas with soap and water.
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.
Change oil while engine is still warm from running, as follows:
1. Make sure unit is on a level surface.
2. Remove oil drain plug and drain oil completely into a
suitable container.
3. Reinstall oil drain plug and tighten securely.
4. Loosen the three maintenance cover screws and
remove the side maintenance cover.
5. Clean area around oil fill, remove dipsitck and wipe
with clean cloth.
6. Slowly pour recommended oil (about 36 oz. (1.0 l))
into oil fill opening. Pause to permit oil to settle. Fill to
