OPERATION
TRIMMING TIPS
WARNING
Debris such as sticks, gravel, and rocks can be thrown
with sufficient force to cause personal injury or property
damage.
• Set the throttle control in the FAST position. The faster the
engine runs, the faster the trimmer head will rotate. If the
weeds or grass are tall and thick, operate the trimmer at a
slower walking speed.
• Frequently clean the trimmer to remove any grass build
up. See the Maintenance section for details.
• For best results and longer lasting line, use the ends of the
line to do the cutting. This is easily done by moving
slowly through very thick or heavy weeds.
• 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 difficult 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 to the height guide.

side loops. (See Figure 13)
5. Take the ends of the line, cross over the line retainer, and
thread the ends through the center hole. (See Figure 14)
6. Then, check to make sure that the ends of the line are
even. (See Figure 15)
7. Follow same steps for line on alternate side.
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 flexible and easy to change.
A flexible line will also last much longer.

MAINTENANCE
HOW TO REPLACE THE DRIVE BELT
WARNING
Before you remove the drive belt, disconnect the wire from
the spark plug.
To replace the drive belt, the trimmer head and shield must
be removed as follows.
1. Remove the two fasteners that hold the rear of the shield
to the trimmer housing. (See Figure 16)
2. Remove the four fasteners that hold the front of the shield
and trimmer head to the trimmer housing.
3. Remove the “V” Pulley from the idler bracket.
(See Figure 17)
4. Raise the front of the trimmer housing and remove the
drive belt. Do not bend the belt guides.
NOTE: Make sure you replace the drive belt only with a
replacement belt from the factory. The length of the belt is
45.67±0.1 in. [1160±2.5mm], the angle is 37°, and the section
is 3L.
5. To assemble the drive belt, reverse the above steps.
6. The torque specs are 9.6-14.8 foot-pounds [13-20 Nm] for
the shield fasteners, 27-33 foot-pounds [36.6-44.7 Nm] for
the drive pulley mounting bolt, and 18-25 foot-pounds
[24.4-34 Nm] for the trimmer head bolts.
7. Check the routing of the drive belt. Make sure the drive
belt is inside of all belt guides and that the belt is not
twisted. (See Figure 17)
IMPORTANT: Test the drive system. Start the engine and
move the throttle control to the FAST position. Engage and
disengage the trimmer head several times. When disen-
gaged, make sure the trimmer head completely stops when
resting on the ground. If the trimmer head continues to
rotate, take the trimmer to an authorized Service Center.

MAINTENANCE
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 flame, a spark or a pilot light
as on a furnace, water heater or clothes dryer. Allow
engine to cool before storing unit.
WARNING
Do not remove gasoline while inside a building, near a
fire, or while you smoke. Gasoline fumes can cause an
explosion or a fire.
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.
IMPORTANT: It is important to prevent gum deposits from
forming in fuel system parts such as the carburetor, fuel
filter, fuel hose, and tank during storage. Also, using alco-
hol-blended fuels (called gasohol, ethanol, or methanol) can
attract moisture, which leads to separation and formation of
acids during storage. Acidic gas can damage the fuel system
of an engine while in storage.
When the trimmer is put in storage for thirty days or more,
follow the steps below to make sure the trimmer is in good
condition the following season.
1. Let the engine run until it is out of gasoline.
2. Change the oil by following instructions under Engine
Maintenance.
Page 17
3. Remove the spark plug from the cylinder. Pour one
ounce of oil into the cylinder. Slowly pull the recoil-start
handle so that the oil will protect the cylinder. Install a
new spark plug in the cylinder. Pull recoil-start handle
slowly a few times to distribute oil.
4. Clean the dirt and debris from the cylinder cooling fins
and the engine housing.
5. Completely clean the trimmer. Remove all dirt, grease,
leaves, etc.
6. Check the trimmer for worn or damaged parts. Have
damaged parts replaced if necessary.
7. Tighten all loose hardware.
8. Apply lubrication as directed in Maintenance section.
9. Put the unit in a building that has good ventilation.
10. Cover the trimmer with a suitable protective cover that
does not retain moisture. Do not use plastic. Plastic can
not breathe which allows condensation to form and will
cause your unit to rust.
11. If desired, fold the handle down for storage. Refer to
the “Adjust the Handle” directions in the Assembly
section. When folding the handle for storage or
transportation, be sure to fold the handle as shown or you
may damage the control cables.
