Maintenance - Ryobi RY907000 Operator's Manual

 If level is low, add engine lubricant until the fluid level rises
to the upper portion of the dipstick.
 Replace and secure the oil cap/dipstick.
USING FUEL STABILIZER
Fuel gets old, oxidizes, and breaks down over time. Adding
a fuel stabilizer (not included) extends the usable life of fuel
and helps prevent deposits from forming that can clog the
fuel system. Follow fuel stabilizer manufacturer's directions
for correct ratio of stabilizer to fuel.
 Mix fuel stabilizer and gasoline prior to filling the tank
by using a gas can or other approved fuel container and
shaking gently to combine.
NOTE: To control the amount of fuel stabilizer being added
to the engine, always mix fuel stabilizer with gasoline
before fueling the tank rather than adding fuel stabilizer
directly into the generator's fuel tank.
 Replace and secure the fuel tank cap.
 Start and run the engine for at least 5 minutes to allow
stabilizer to treat the entire fuel system.
ETHANOL-BLENDED FUELS
NOTICE:
Do not use E15 or E85 fuel in this product. It is a viola-
tion of federal law and will damage the unit and void
your warranty. Only use unleaded gasoline containing
up to 10% ethanol.
CHECKING/ADDING FUEL
See Figure 11.
DANGER:
Risk of fire and serious burns: Never remove fuel cap
when unit is running. Shut off engine and allow the unit
to cool at least five minutes. Remove cap slowly.
WARNING:
Gasoline and its vapors are highly flammable and ex-
plosive. To prevent serious personal injury and property
damage, handle gasoline with care. Keep away from igni-
tion sources, handle outdoors only, do not smoke while
adding fuel, and wipe up spills immediately.
When adding gas to the generator, make sure the unit is sitting
on a flat, level surface. If the engine is hot, let the generator
cool for five minutes before adding gas. ALWAYS fill the fuel
tank outdoors with the machine turned off.
 Turn the fuel valve to the OFF (O) position.
 Remove the fuel cap slowly.
 Fill the fuel tank to 1 in. below the top of the fuel neck.
 Replace and secure the fuel cap.
OPERATION
WARNING:
Always shut off engine before fueling. Never remove
fuel cap or add fuel to a machine with a running or hot
engine. Make sure the unit is sitting on a flat, level sur-
face and only add fuel outdoors. If the engine is hot, let
the unit cool for at least five minutes before adding fuel.
After fueling, immediately replace fuel cap and tighten
securely. Move at least 30 ft. from refueling site before
starting engine. Do not smoke and stay away from open
flames and sparks! Failure to follow these instructions
could result in a fire and cause serious personal injury.
NOTE: Always use unleaded gasoline with a pump octane
rating of 86 or higher. Never use old, stale, or contaminated
gasoline, and do not use a lubricant/gas mixture. Do not
allow dirt or water into the fuel tank. Do not use E85 fuel.
DIGITAL DISPLAY
See Figure 12.
Press and release the mode button to cycle through the
following displays:
Voltage (V) displays the operating voltage of the generator.
Frequency (F) displays the frequency in hertz at which the
generator is running.
The Run/Maintenance Timer displays the amount of time
the generator has run since being started. This timer resets
each time the generator is shut off.
When a cumulative run time of 25 hours has been reached,
P25 will display on the meter as a reminder to change the
engine lubricant after the initial 25 hours of run time.
When a cumulative time of 50 hours is reached, P50 will
display on the meter to remind you to clean the air filter.
When a cumulative time of 100 hours is reached, P100 will
display on the meter to remind you to change/clean the fuel
filter, clean the air filter, and change the engine lubricant.
ELECTRIC START
This generator model is provided with both electric start and
recoil start capabilities. Avoid prolonged cranking, as it can
damage the engine.
The battery provided is a nominal 12 volt sealed rechargeable
lead-acid battery and can be operated in any position without
leakage. It complies with non-spillable battery regulations.
Its convenient size offers a 30% reduction over conventional
batteries.
NOTE: Brand new generators are shipped with the battery
connections disconnected. The positive and negative
terminals must be connected to the battery before the Electric
Start feature will work.
For initial battery connection, see Connecting/Disconnecting
Battery.
