Normal maintenance, replacement or repair of emission con-
trol devices and systems may be performed by any qualified
repair establishment or individual with original or equivalent
parts. Warranty and recall repairs must be performed by an
authorized service center; please contact customer service
for assistance.
WARNING:
Before inspecting, cleaning or servicing the machine, shut
off engine, wait for all moving parts to stop, and disconnect
spark plug wire and move it away from spark plug. Allow
30 minutes of cool down time before performing any
maintenance. Failure to follow these instructions can result
in serious personal injury or property damage.
WARNING:
When servicing, use only recommended or equivalent
replacement parts. Use of any other parts could create
a hazard or cause product damage.
WARNING:
DO NOT tamper with, adjust, or modify the carbon mon-
oxide (CO) sensor module on your generator. Failure to
follow these instructions can cause the monitor to mal-
function which can result in death or serious personal
injury.
NOTICE:
Periodically inspect the entire product for damaged,
missing, or loose parts such as screws, nuts, bolts,
caps, etc. Tighten securely all fasteners and caps and
do not operate this product until all missing or damaged
parts are replaced. Please contact customer service or
a qualifed service center for assistance.
GENERAL MAINTENANCE
Keep the generator in a clean and dry environment where it
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.
To clean the unit:
Use a soft bristle brush and/or vacuum cleaner to loosen
and remove dirt and debris.
Clean air vents with low pressure air that does not exceed
25 psi.
Wipe the exterior surfaces of the generator with a damp
cloth.
CHECKING/CLEANING AIR FILTER
See Figures 12.
For proper performance and long life, keep air filter clean.
Rotate knob counterclockwise to release. Remove cover
and set aside.
Remove the filter element.
If the filter element is dirty, clean with warm, soapy water.
Rinse and let dry.
Apply a light coat of engine lubricant to the element, then
squeeze it out.
Replace the element in the air filter unit.
Replace the air filter cover and rotate knob clockwise to
secure.
NOTE:
Make sure the filter is seated properly inside the
generator. Installing the filter incorrectly will allow dirt to
enter the engine, causing rapid engine wear.
CHANGING ENGINE LUBRICANT
See Figure 13.
For best performance, engine lubricant should be changed
after every 100 hours or 6 months of operation.
Remove the oil fill cap/dipstick.
Unscrew the oil drain plug and remove.
Allow lubricant to drain completely 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.
Reinstall the oil drain plug and tighten securely.
Refill with lubricant following the instructions in the
Checking/Adding Lubricant
section. 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.
NOTE:
Used lubricant should be disposed of at an approved
disposal site. See your local retailer for more information.
