OIL AND FUEL INFORMATION
12
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 instruc-
tions carefully for the proper fuel/oil mixture.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates 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 additives, such as STA-BIL®Gas
Stabilizer or an equivalent, will inhibit corrosion and
minimize the formation of gum deposits. Using a fuel
additive 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.
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.

release more line, lightly tap the cutting attachment on
the ground (Fig. 18) while operating the trimmer at high
speed.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult as cutting
line becomes shorter.
Fig. 18
Each time the head is bumped, about 1 in (25.4 mm.) of
trimming line is released. A blade in the cutting attachment shield will cut the line to the proper length if excess
line is released. For best results, tap the Bump Head™
on bare ground or hard soil. If line release is attempted
in tall grass, the engine may stall. Always keep the
trimming line fully extended. Line release becomes more
difficult as the cutting line becomes shorter.
NOTE: Do not rest the Bump Head™ on the ground.
CAUTION: Do not remove or alter the line
cutting blade assembly. Excessive line length
will make the clutch overheat. This may lead
to serious personal injury or damage to the
unit.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds
• Forcing the line into objects such as walls or fence
posts
TIPS FOR BEST TRIMMING RESULTS
• Keep the cutting attachment parallel to the ground.
• Do not force the cutting attachment. Allow the tip of
the line to do the cutting, especially along walls.
Cutting with more than the tip will reduce cutting efficiency and may overload the engine.
• Cut grass over 8 in. (200 mm.) by working from top
to bottom in small increments to avoid premature
line wear or engine drag.
• Cut from left to right whenever possible. Cutting to
the right improves the unit's cutting efficiency.
Clippings are thrown away from the operator.
• Slowly move the trimmer into and out of the cutting
area at the desired height. Move either in a forwardbackward or side-to-side motion. Cutting shorter
lengths produces the best results.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon;
• Following the previous trimming
techniques
• What vegitation is being cut
• Where it’s being cut
For example, the line will wear faster when trimming
against a foundation wall as opposed to trimming
around a tree.
WARNING: The cutting attachment shield
must be installed when operating either the
cutting attachment or flail head.
OPERATING INSTRUCTIONS
15
NOTE: Some maintenance procedures may require
special tools or skills. If you are unsure about
these procedures take your unit to an authorized
service dealer.
MAINTENANCE SCHEDULE
These required maintenance procedures should be
performed at the frequency stated in the table. They
should also be included as part of any seasonal tune-up.
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences, etc.
Rotate the whole unit so that the cutting attachment is at
a 30° angle to the ground (Fig. 19).
Before operating the unit with the Flail Head stand in the
operating position (Figs. 20). Refer to Holding the
Trimmer, Pg. 14.
WARNING: To avoid serious personal injury
and damage to the unit, do not use the flail
head assembly for decorative trimming or
cutting brush.
Flail Head Operating Tips:
To establish a rhythmic cutting procedure:
• Plant feet firmly, comfortably apart.
• Bring the engine to full throttle before entering the
material to be cut. The blade has maximum cutting
power at full throttle and is less likely to bind, stall, or
cause blade thrust, which can result in serious personal injury to the operator or others.

OPERATING THE FLAIL HEAD
Your unit can be equipped with a Flail Head that is better
suited for use on thick grass and weeds (Fig. 20).
MAINTENANCE REQUIRED
Fill fuel tank with correct oil and fuel mixture.
Clean and re-oil air filter.
Check spark plug condition and gap.

CARBURETOR ADJUSTMENT
The idle speed of the engine is adjustable though the Air
filter/muffler cover (Fig 33).
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 screw. Refer to
Air Filter Maintenance Pg. 18.
5. Squeeze the filter to spread and remove excess oil
(Fig. 32).
Adjust Idle Speed Screw
WARNING: The cutting attachment may be
spinning during idle speed adjustment. Wear
protective clothing and observe all safety
instructions to prevent serious personal
injury.
If after checking the fuel mixture and cleaning the air filter the engine still will not idle, adjust the idle speed
screw as follows.
1. Start the engine and let it run at a high idle for a
minute to warm up.
2. Release the throttle trigger 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. 33). Turn the idle speed screw in, clockwise, 1/8
of a turn at a time (as needed) until the engine idles
smoothly.
NOTE: The cutting attachment should not rotate when
the engine idles.
3. If the cutting attachment rotates when the engine
idles, turn the idle speed screw 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.
WARNING: When the unit is turned off make
sure the cutting attachment has stopped
before the unit is set down to prevent serious
personal injury.
