MAINTENANcE
Tilt the generator to the side and allow lubricant to drain
from the oil fill hole into an approved container.
NOTE: Drain the lubricant while the engine is still warm 
but not hot. Warm lubricant will drain quickly and more 
completely.
WARNINg:
Do not change engine lubricant while it is hot. Accidental 
contact with hot engine lubricant could result in serious 
burns.
Return the generator to an upright position and refill with
lubricant following the instructions in the
checking/
Adding Lubricant section previously in this manual. 
For amount of lubricant needed to refill, see 
Product
Specifications earlier in this manual or the accompanying 
engine manual, if applicable.
Replace and secure the oil cap/dipstick.
Reinstall the engine cover. Replace the screw and tighten
securely.
NOTE: Used lubricant should be disposed of at an approved 
disposal site. See your local retailer for more information.
SPARK PLUg REPLAcEMENT
See Figure 13.
The spark plug must be properly gapped and free of deposits 
in order to ensure proper engine operation. To check:
Remove the spark plug cover.
Remove the spark plug cap.
Clean any dirt from around base of spark plug.
Remove spark plug using spark plug wrench.
Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or 
chipped, spark plug should be replaced. For replacement 
spark plug, see 
Product Specifications earlier in this
manual or the accompanying engine manual, if applicable.
Measure plug gap. The correct gap is 0.024−0.028 in.
(0.60-0.70 mm). To widen gap, if necessary, carefully 
bend the ground (top) electrode. To lessen gap, gently 
tap ground electrode on a hard surface.
Seat spark plug in position; thread in by hand to prevent
cross-threading.
Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate 
amount. If reusing old spark plug, use 1/8 to 1/4 turn for 
proper washer compression. 
NOTE: An improperly tightened spark plug will become 
very hot and could damage the engine.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product. 
WARNINg:
When servicing, use only identical replacement parts. 
Use of any other parts could create a hazard or cause 
product damage.
WARNINg:
Always wear eye protection with side shields marked to 
comply with ANSI Z87.1. Failure to do so could result in 
objects being thrown into your eyes, resulting in possible 
serious injury.

is not exposed to dust, dirt, moisture, or corrosive vapors. 
Do not allow the cooling air slots in the generator to become 
clogged with foreign material such as leaves, etc.
Do not use a garden hose to clean the generator. Water 
entering the fuel system or other internal parts of the unit can 
cause problems that will decrease the life of the generator.
