MAINTENANCE

WARNING:
When servicing, use only identical Ryobi
replacement parts. Use of any other parts may
create a hazard or cause product damage.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts should
be replaced at an authorised service centre.
GENERAL MAINTENANCE
Keep the generator in a clean and dry environment where it
is not exposed to dust, dirt, moisture, or corrosive vapours.
Do not allow the cooling air slots in the generator to become
clogged with foreign material such as leaves, snow, 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
n
loosen and remove dirt and debris.
Clean air vents with low pressure air that does not
n
exceed 25 psi.
Wipe the exterior surfaces of the generator with a
n
damp cloth.
CHECKING/CLEANING AIR FILTER
See Figure 9.
For proper performance and long life, keep air filters clean.
Lift the latches located at the top and bottom of the
n
air filter cover. Remove the cover and set aside.
Remove the filter elements.
n
If the filter elements are dirty, clean with warm, soapy
n
water. Rinse and let dry.
Apply a light coat of engine oil to the elements, then
n
squeeze it out.
Replace the elements in the air filter unit.
n
Replace the air filter cover and close latches to
n
secure.
NOTE: Do not run the generator without the air filter.
Rapid engine wear will result.
CHANGING ENGINE OIL
See Figure 10.
Remove the oil cap/dipstick.
n
Place a container underneath the oil drainage plug to
n
collect used oil as it drains.
Unscrew the oil drainage plug and remove.
n
Allow oil to drain completely.
n
Reinstall the oil drainage plug and tighten securely.
n
Refill with oil following the instructions in the
n
Checking/Adding Oil section.
Reinstall the oil cap/dipstick.
n
NOTE: Used oil should be disposed of at an approved
disposal site. See your local oil retailer for more
English
information.
CLEANING FUEL SEDIMENT CUP
See Figure 11.
The sediment cup prevents dirt and water that may have
gotten into the fuel tank from entering the carburetor. If the
engine has not been run for a long time, the sediment cup
should be cleaned before use.
Turn the fuel valve to the OFF position.
n
Remove the sediment cup using a 10 mm wrench
n
(not provided).
Remove the O-ring and filter.
n
Clean each of the parts in carburetor cleaner or any
n
comparable cleaning product.
Reinstall the filter, O-ring, and sediment cup. Tighten
n
with wrench to secure.
Return the fuel valve to ON position and check for
n
leaks.
SPARK PLUG MAINTENANCE
See Figure 12.
The spark plug must be properly gapped and free of deposits
in order to ensure proper engine operation. To check:
Remove the spark plug cap.
n
Clean any dirt from around base of spark plug.
n
Remove spark plug using wrench provided.
n
Inspect spark plug for damage, and clean with a wire
n
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced.
NOTE: If replacing, use the following recommended
spark plugs or equivalent: Champion RN11YC or
NGK BPR6ES.
Seat spark plug in position; thread in by hand to
n
prevent cross-threading.
Tighten with wrench to compress washer. If spark
n
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.
CLEANING THE EXHAUST PORT AND MUFFLER
Depending on the type of fuel used, the type and amount of
oil used, and/or your operating conditions, the exhaust port
and muffler may become blocked with carbon deposits. If
you notice a power loss with your petrol-powered tool, you
may need to remove these deposits to restore performance.
We highly recommend that only qualified service technicians
perform this service.
