ADDING ENGINE OIL
All oil should meet minimum American Petroleum Institute (API)
Service Class SJ, SL or better. Do not use any aftermarket
additives.
Select the oil's viscosity grade according to the expected operating
temperature.
• Above 40° F, use SAE 30
• Below 40° F to 10° F, use 10W-30
• Below 10° F, use synthetic 5W-30

TO ADD ENGINE OIL TO THE CRANKCASE
1. Place the unit on a firm, level surface (not to exceed 15° in any
direction).
2. Remove the Left Side Service Cover.
3. Remove the oil fill cap located on the bottom of the engine
crankcase.
4. Add the recommended engine oil slowly, stopping frequently
to check the level. The full level is the base of the threads in
the filler neck. DO NOT OVERFILL!
5. Replace the oil fill cap and tighten.
6. Always check the oil level before starting the generator
engine.
DO NOT overfill the engine crankcase with
oil. High oil pressure may result, causing
premature engine wear and damage.

GENERATOR MAINTENANCE
Proper care will ensure maximum performance of your generator.
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.
Check the cleanliness of the generator frequently and clean when
dust, dirt, oil, moisture or other foreign substances are visible on
its exterior surface.
NOTE:
Never insert any object or tool through the air cooling slots,
even if the engine is not running.
NOTE:
DO NOT use a garden hose to clean the generator. Water
can enter the engine fuel system and cause problems. In
addition, if water enters the generator through cooling air
slots, some water will be retained in voids and crevices of the
rotor and stator winding insulation. Water and dirt buildup on
the generator internal windings will eventually decrease the
insulation resistance of these windings.
