OIL AND FUEL INFORMATION
12
WARNING: Gasoline is extremely
flammable. Ignited Vapors may explode.
Always stop the engine and allow it to cool
before filling the fuel tank. Do not smoke
while filling the tank. Keep sparks and open
flames at a distance from the area.
WARNING: Remove fuel cap slowly to avoid
injury from fuel spray. Never operate the unit
without the fuel cap securely in place.
WARNING: Add fuel in a clean, well
ventilated area outdoors. Wipe up any spilled
fuel immediately. Avoid creating a source of
ignition for spilt fuel. Do not start the engine
until fuel vapors dissipate.
NOTE: Dispose of the old fuel/oil mix in accordance to
Federal, State, and Local regulations.
OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons
for the unit not running properly. Be sure to use fresh,
clean unleaded fuel. Follow the instructions carefully for
the proper fuel/oil mixture.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxy-
genates such as ethanol, methanol or MTBE (ether).
Alcohol-blended fuel absorbs water. As little as 1%
water in the fuel can make fuel and oil separate. It forms
acids when stored. When using alcohol-blended fuel,
use fresh fuel (less than 60 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is
unavoidable, follow recommended precautions.
•Always use fresh fuel mix per your operator's manual.
•Use the fuel additive STA-BIL®or an equivalent.
•Always agitate the fuel mix before fueling the unit.
•Drain the tank and run the engine dry before storing
the unit.
Using Fuel Additives
The use of fuel additive, such as STA-BIL®Gas
Stabilizer or an equivalent, will inhibit corrosion and mini-
mize the formation of gum deposits. Using a fuel addi-
tive can keep fuel from forming harmful deposits in the
carburetor for up to six (6) months. Add 0.8 oz. (23 ml.)
of fuel additive per gallon of fuel according to the
instructions on the container. NEVER add fuel additives
directly to the unit's fuel tank.
CAUTION: For proper engine operation and
maximum reliability, pay strict attention to the
oil and fuel mixing instructions on the 2-cycle
oil container. Using improperly mixed fuel can
severely damage the engine.
Thoroughly mix the proper ratio of 2-cycle engine oil
with unleaded gasoline in a separate fuel can. Use a 32:1
fuel/oil ratio. Do not mix them directly in the engine fuel
tank. See the table below for specific gas and oil mixing
ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed
with one 4 oz. (120 ml.) bottle of RYOBI 2 CYCLE
OIL makes a 32:1 fuel/oil ratio.

might be disturbed. Comply with time listed in local
ordinance. Usual recommendations are 9:00 am to
5:00 pm, Monday through Saturday.
•To reduce noise levels, limit the number of pieces of
equipment used at any one time.
•To reduce noise levels, operate power blowers at the
lowest possible speed to do the job.
•Check your equipment before operation, especially
the muffler, air intakes, and air filters.
•Use rakes and brooms to loosen debris before
blowing.
•In dusty conditions, slightly dampen surfaces or use
a mister attachment when water is available.
•Conserve water by using power blowers instead of
hoses for many lawn and garden applications,
including areas such as gutters, screens, patios,
grills, porches, and gardens.
•Watch out for children, pets, open windows, or
freshly washed cars, and blow debris away.
•After using blowers and other equipment, CLEAN
UP! Dispose of debris in trash receptacles.

CARBURETOR SETTING
The idle speed adjuster of the engine is adjustable
though the Air filter/muffler cover (Fig 26).
NOTE: Careless adjustments can seriously damage your
unit. An authorized service dealer should make
carburetor adjustments.
Check Fuel Mixture
Old and/or improperly mixed fuel is usually the reason
for the unit not running properly. Drain and refill the tank
with fresh, properly mixed fuel prior to making any
adjustments. Refer to Oil and Fuel Information, Pg. 12.
Clean Air Filter
The condition of the air filter is important to the
operation of the unit. A dirty air filter will restrict air flow
and change the air/fuel mixture. This is often mistaken
for an out of adjustment carburetor. Check the condition
of the air filter before adjusting the idle speed adjuster.
Refer to Air Filter Maintenance Pg. 17.
Adjust Idle Speed Adjuster
WARNING: This unit will need to be running
during idle speed adjustment. Wear
protective clothing and observe all safety
instructions to prevent serious personal
injury.
Also, Do not set unit on any surface except a
clean, hard area while starting or performing
any adjustments. Debris such as gravel,
sand, dust, grass, etc. could be picked up
by the air intake and thrown out by the
discharge opening, damaging unit, property,
or causing serious injury to bystanders or
operator.
If after checking the fuel mixture and cleaning the air
filter the engine still will not idle, adjust the idle speed
adjuster as follows.
1. Start the engine and let it run at a high idle for a
minute to warm up.
2. Set the blower/vacuum mode change-over lever to
the up position (Blower Mode). See Operating as a
Blower, Pg. 15.
NOTE: Setting the lever to the blower mode prevents
the vacuum bag from filling up while starting or
running the unit.
3. Move the throttle control and let the engine idle. If
the engine stops, insert a small phillips or flat blade
screwdriver into the hole in the air filter/muffler cover
(Fig. 26). Turn the idle speed adjuster in, clockwise,
1/8 of a turn at a time (as needed) until the engine
idles smoothly.
4. If the unit appears to be idling too fast, turn the idle
speed adjuster counterclockwise 1/8 of a turn at a
time (as needed), to reduce idle speed.
Checking the fuel mixture, cleaning the air filter, and
adjusting the idle speed screw should solve most engine
problems.
If not and:
•The engine will not idle,
•The engine hesitates or stalls on acceleration,
•There is a loss of engine power,
have the carburetor adjusted by an authorized service
dealer.

Fig. 26
REPLACING THE SPARK PLUG
Use a Champion RDJ7Y spark plug (or equivalent). The
correct air gap is 0.020 in. (0.5 mm.). Remove the plug
after every 50 hours of operation to check its condition.
1. Stop the engine and allow it to cool. Grasp the plug
wire firmly and pull the cap from the spark plug.
2. Clean dirt from around the spark plug. Remove the
spark plug from the cylinder head by turning a 5/8 in.
socket counterclockwise.
Note: Replace cracked, fouled or dirty spark plug.
3. Set the air gap at 0.020 in. (0.5 mm.) using a feeler
gauge (Fig. 27).
0.020 in.
