OIL AND FUEL INFORMATION
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 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 the fresh fuel mix explained in your operator's manual
• 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 bottle of 2-cycle oil that came with your unit contains a fuel additive which will help inhibit corrosion and
minimize the formation of gum deposits. It is recommended that you use our 2-cycle oil with this unit.
If unavailable, use a good 2-cycle oil designed for
air-cooled engines along with a fuel additive, such as
STA-BIL®Gas Stabilizer or an equivalent. 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.
Thoroughly mix the proper ratio of 2-cycle engine oil
with unleaded gasoline in a separate fuel can. Use a
40:1 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 3.2 oz. (95 ml.) bottle of
2-cycle oil makes a 40:1 fuel/oil ratio.
UNLEADED GAS 2 CYCLE OIL
1 GALLON US
(3.8 LITERS)
3.2 FL. OZ.
(95 ml)
1 LITER 25 ml
+
MIXING RATIO - 40:1
Add fuel in a clean,
well ventilated outdoor area. Wipe up any spilled fuel immediately. Avoid creating a source of ignition for
spilt fuel. Do not start the engine until fuel
vapors dissipate.
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:
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.
CAUTION:
NOTE: If your engine is damaged from insufficient lubrica-
tion, it voids the manufacturer’s warranty. Straight
gasoline in the unit also voids the warranty.

STARTING A COLD ENGINE
NOTE: To minimize the load on the engine during starting
and warm-up, trim any excess trimming line.
Leave about 5 inches (13 cm) of line from the
cutting attachment (Fig. 5).
1. Mix gas with oil. Fill fuel tank with fuel/oil mixture.
See Oil and Fuel Mixing Instructions.
2. Move the ignition switch to the Run position (Fig. 6).
3. Move choke lever to Position 1 (Fig. 7).
4. Prime the carburetor by fully pressing and releasing
the primer bulb 10 times (Fig. 8).
5. Grip the handle firmly and press the safety trigger
and press/squeeze the throttle trigger to the Full
Throttle position (Fig. 6).
6. Pull the starter rope out a short way until you feel
resistance (approximately 4”). Then continue with a
smooth rapid pull (for a strong spark). Pull the rope
briskly in this manner 4 times (Fig. 9).
7. Move the choke lever to Position 2.
8. With the throttle trigger still in the Full Throttle
position, pull the starter rope 4 more times.
9. When the engine starts, leave the choke lever in
Position 2 for about 10 seconds, so the unit can
warm up.
10. Move the choke lever to Position 3. The trimmer is
ready for use.
If engine fails to start, repeat everything from Step 2 on.
NOTE: Always pull the starter rope straight out. If you pull it
at an angle, the rope will rub against the eyelet. This
friction may cause the rope to fray a wear more
quickly . Always hold the starter handle when the
rope retracts. Never allow the rope to snap back
from an extended position. This could damage the
starter assembly or cause the rope to snag.
NOTE: Idling Information: in some cases due to
operating conditions (extreme altitude,
temperature, etc.), your unit may need a slight
adjustment to its idle speed. If your unit does not
idle after restarting two times, refer to Adjusting
the Idle Speed.
STARTING A WARM ENGINE
1. Move the ignition switch to the Run position (Fig. 6).
2. Move choke lever to Position 1 (Fig. 7).
3. Grip the handle firmly and press/hold the safety
trigger. Then press the throttle trigger to the Full
Throttle position (Fig. 6).
4. Pull the starter rope briskly until the engine starts. Do
NOT pull it more than 6 TIMES. Keep the throttle
trigger at the Full Throttle position until the engine
runs smoothly.
NOTE: If the engine doesn’t start, place the choke in
Position 3 and pull the starter rope 5 times. If the
engine doesn’t then start, the engine is probably
flooded. Wait 5 minutes and then repeat the
procedure with the choke in Position 3 and the
throttle trigger in Full Throttle.

OPERATING INSTRUCTIONS
Fig. 10
Fig. 11
DO NOT use steel
wire or plasticcoated steel wire of any kind with your
stringhead. Serious operator injury can result.
WARNING:
Periodically remove
wrapped weeds to
prevent overheating the drive shaft. W eed
wrap occurs when strands of weeds become
entangled around the shaft beneath the
debris shield (Fig. 11). This condition prevents
the shaft from cooling properly. Remove weed
wrap with a screwdriver or a similar device.
CAUTION:
ADJUSTING TRIMMING LINE LENGTH
To release fresh line, run engine at full throttle and
“bump” stringhead against lawn. Line will automatically
release. The blade in debris shield will trim excess line
(Fig. 10).
TRIMMING PROCEDURES
NOTE: Even with care, trimming around foundations,
brick or stone walls, curves, etc., will result in
above normal string wear.
Trimming / Mowing
Swing trimmer with a sickle-like motion from side to
side. Do not tilt the stringhead during the procedure.
Test area to be trimmed for proper cutting height. Keep
stringhead at same level for even depth of cut (Fig. 12).
Closer Trimming
Position trimmer straight ahead with a slight tilt so
bottom of stringhead is above ground level and string
contact occurs at proper cutting point. Always cut away
from operator. Do not pull trimmer in toward operator.
Fence / Foundation Trimming
Approach trimming around chain link fences, picket
fences, rock walls and foundations slowly to cut close
without whipping string against the barrier. If the string
comes in contact with rock, brick walls, or foundations,
it will break or fray. If string snags fencing, it will snap off.
Trimming Around Trees
Trim around tree trunks with a slow approach so string
does not contact bark. Walk around the tree trimming
from left to right. Approach grass or weeds with the tip
of the string and tilt stringhead slightly forward.
Fig. 12
Scalping
Scalping refers to removal of all vegetation down to the
ground. To do this, tilt the stringhead to about a 30
degree angle to the left. By adjusting the handle you will
have better control during this operation. Do not attempt
this procedure if there is any chance flying debris could
injure operator, other people or cause damage to
property.
DO NOT sweep
with trimmer.
Sweeping refers to tilting stringhead to
sweep away debris from walkways, etc.
Your trimmer is a powerful tool and small
stones or other such debris may be hurled
50 feet (15 m) or more, causing injury or
damage to nearby property such as
automobiles, homes and windows.
WARNING:
Use extreme
caution when
scalping. Keep a distance of 100 feet (30 m)
between operator, other people and
animals during these operations.
