CAUTION
Trimmer line will continue to rotate for several seconds after releasing the control lever. Use Caution.
WARNING
Debris such as sticks, gravel, and rocks can be thrown with
sufcient force to cause personal injury or property damage.
• Frequently clean debris and grass build up from the
recoil starter cover holes, under the deck in the trimming
head area, and around the mufer. Using the unit with
excessive debris can risk re. Always use extreme
caution when using the trimmer during dry conditions.
• If the trimmer lines become too short, it will take longer
to complete this job. If the trimmer lines are worn to less
than half their original length, change to a new trimmer
line. See “How to Replace the Trimmer Line” in the
Maintenance section.
• Do not trim on excessively steep slopes. See Slope
Guide. If a slope is difcult to stand on, do not trim it. Do
not trim on slopes when the ground is slippery or wet.
Trim across the face of a slope, not up and down.
• Trimmer head contact to concrete, asphalt and harder
surfaces may create premature wear.
• For best results and longer lasting line, soak the trimmer
line in a pail of water for 24 hours prior to use. A moist
line will be more exible than a dry, brittle line.
• Let the ends of the trimming line do the cutting. This is
easily done by moving slowly through very thick or heavy
weeds.

How to Replace the Trimmer Lines
When the trimmer line becomes worn to half the original
length, replace the trimmer line. For the best performance,
use a heavy gauge 0.155 in. [4 mm] trimmer line.
1. Stop the engine. Wait for all moving parts to stop.
Disconnect the wire from the spark plug.
2. Remove the worn trimmer line from line retainer.
3. Cut the length of the trimmer line to 21.5 in. [546 mm].
Use the length guide; located on the shield to make sure
the trimmer line is the correct length. (See Figure 11)
NOTE: Do not allow the length of the lines to vary more than
one inch. Make sure the trimmer head is balanced and does
not vibrate.
IMPORTANT: To extend the life of the trimmer line, keep the
trimmer line moist. If not kept moist, the nylon trimmer line
will become dry and brittle. Keep extra trimmer line in a can
of water. The line will then stay exible and easy to change.
A exible line will also last much longer.

How to Prepare for Storage
WARNING
Never store the trimmer indoors with fuel in the fuel tank.
Never store in an enclosed, poorly ventilated area where
fumes could reach an open ame, a spark or a pilot light as
on a furnace, water heater or clothes dryer. Allow engine to
cool before storing unit.
Do not remove gasoline while inside a building, near a re,
or while you smoke. Gasoline fumes can cause an
explosion or a re.
NOTE: A yearly checkup or tune-up at an authorized service
center will make sure that the trimmer will provide maximum
performance for the next season.
When the trimmer is put in storage for thirty days or more,
the following steps should be followed to make sure the
Trimmer is in good condition the next season. To prevent
fuel gum deposits and corrosion in the unit’s carburetor and
fuel system, it is highly recommended to use a fuel additive/
stabilizer formulated for ethanol fuels.. Follow the stabilizer
manufacturer’s instructions. Run the engine for at least 5
minutes after adding stabilizer.
1. Let the engine run until it is out of gasoline. Remove
carburetor screw from bowl and drain fuel. Tilt the unit
slightly to remove all fuel. Replace screw.
