general recommendations
Regular maintenance will improve the performance and extend the life of the generator.
See any authorized dealer for service.
The generator's warranty does not cover items that have been subjected to operator
abuse or negligence. To receive full value from the warranty, the operator must
maintain the generator as instructed in this manual.
NOTICE Improper treatment of generator could damage it and shorten its life.
• NEVER operate generator without protective housing or covers to assure proper
cooling.
Some adjustments will need to be made periodically to properly maintain your
generator.
All service and adjustments should be made at least once each season. Follow the
requirements in the Maintenance Schedule chart above.
NOTICE Once a year you should clean or replace the spark plug and replace the air
filter. A new spark plug and clean air filter assure proper fuel-air mixture and help your
engine run better and last longer.

generator Maintenance

Generator maintenance consists of keeping the unit clean and dry. Operate and store
the unit in a clean dry environment where it will not be exposed to excessive dust, dirt,
moisture, or any corrosive vapors. Cooling air slots in the generator must not become
clogged with snow, leaves, or any other foreign material.
NOTICE DO NOT use water or other liquids to clean generator. Liquids can enter
engine fuel system, causing poor performance and/or failure to occur. In addition, if
liquid enters generator through cooling air slots, some of the liquid will be retained in
voids and cracks of the rotor and stator winding insulation. Liquid and dirt buildup on
the generator internal windings will eventually decrease the insulation resistance of
these windings.
cleaning
Daily or before use, look around and underneath the generator for signs of oil or fuel leaks.
Clean accumulated debris from inside and outside the generator. Inspect cooling air slots
and openings on generator. These openings must be kept clean and unobstructed.
Engine parts should be kept clean to reduce the risk of overheating and ignition of
accumulated debris:
• Use a damp cloth to wipe exterior surfaces clean.
NOTICE Improper treatment of generator could damage it and shorten its life.
• DO NOT expose generator to excessive moisture, dust, dirt, or corrosive vapors.
• DO NOT insert any objects through cooling slots.
• Use a soft bristle brush to loosen caked on dirt or oil.
• Use a vacuum cleaner to pick up loose dirt and debris.

cleaning Fuel strainer
The fuel strainer helps prevent debris from entering the fuel system.
clean the fuel strainer as follows:
1. Make sure generator is on a level surface.
2. Remove the fuel cap (a) and fuel strainer (B).
3. Wash fuel strainer in liquid detergent and water.
4. Wipe fuel strainer clean with a clean, dry cloth.
5. Carefully reinstall the fuel strainer and fuel cap.

engine Maintenance

warning Unintentional sparking could cause fire or electric shock resulting
in death or serious injury.
wHen adJusting or Making rePairs to your generator
• Disconnect the spark plug wire from the spark plug and place the wire where it
cannot contact spark plug.
wHen testing For engine sPark
• Use approved spark plug tester.
• DO NOT check for spark with spark plug removed.
oil
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.
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. Loosen the side maintenance cover screws and remove the side maintenance
cover.
3. Clean area around oil fill and remove oil fill cap.
4. Verify oil is at the point of overflowing at oil fill opening.
5. Replace and tighten oil fill cap.
6. Reinstall the side maintenance cover and hand tighten the cover screws.

adding engine oil
1. Make sure generator is on a level surface.
2. Repeat steps 2 through 4 to 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.
5. Reinstall the side maintenance cover and hand tighten the cover screws.
