1. Read, understand, and follow all instructions on the machine and in the manual(s). Be thoroughly familiar with the
controls and the proper use of the machine before starting.
2. Familiarise yourself with all of the safety
and operating decals on this equipment
and on any of its attachments or accessories.
3. Do not put hands or feet near or under
rotating parts.
4. Only allow responsible individuals, who
are familiar with the instructions, to operate the machine.
276798MA DRAFT COPY
5. Inspect the area where the machine is to
be used. Your equipment can propel
small objects at high speed causing personal injury or property damage. Stay
away from breakable objects, such as
windows, greenhouses, etc.
6. Keep the area of operation clear of all
persons, particularly small children, and
pets.
7. Wear appropriate clothing such as a
long−sleeved shirt or jacket. Also wear
long trousers. Do not wear shorts.
8. Do not wear loose clothing which could
get caught in this equipment.
9. Always wear safety goggles or safety
glasses with side shields when operating
the machine to protect your eyes from
foreign objects which can be thrown
from the unit.
10. Always wear work gloves and sturdy
footwear. Leather work shoes or short
boots work well for most people. These
will protect the operator’s ankles and
shins from small sticks, splinters, and
other debris, and improve traction.
11. It is advisable to wear protective headgear to prevent the possibility of being
struck by small flying particles, or being
struck by low hanging branches, twigs,
or other objects which may be unnoticed
by the operator.
12. Do not operate the machine without
proper guards or other safety protective
devices in place.
13. Use this equipment for its intended purpose only.
14. See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by
the manufacturer.
15. Operate only in daylight or good artificial
light.
16. Do not operate the machine while under
the influence of alcohol, drugs or other
medication which can cause drowsiness
or affect your ability to operate this machine safely.
17. Never operate machine in wet grass. Always be sure of your footing; keep a firm
hold on the handle and walk; never run.
4
18. Before each use, inspect the throttle
SAFETY RULES
control lever and cable. Make sure that
the cable is free and that the lever is not
damaged. Also check the cable linkage
running to the carburetor for kinks, loose
fittings, and obstructions. Verify that the
control bail is working properly.
19. Stop the rotating trimmer head when
crossing gravel drives, walks, or roads.
Wait for the cutting lines to stop rotating.
20. Watch for traffic when operating near, or
when crossing roads.
21. Stop the engine whenever you leave the
equipment, before cleaning repairing or
inspecting the unit, be sure the trimmer
head and all moving parts have stopped.
Let the engine cool, disconnect the
spark plug wire and move it away from
the spark plug.
22. If the equipment should start to vibrate
abnormally, stop the engine, disconnect
the spark plug wire and prevent it from
touching the spark plug. Check immediately for the cause. Vibration is generally
a warning of trouble.
23. After striking a foreign object, stop the
engine. Remove the wire from the spark
plug. Inspect the machine for damage. If
damaged, repair before starting and operating the machine.
24. Never leave the machine unattended
when the engine is running. Remove
the wire from the spark plug.
25. Regularly inspect the machine. Make
sure parts are not bent, damaged or
loose.
26. Never pick up or carry the machine while

27. Prolonged exposure to noise and vibration from petrol engine powered equipment should be avoided. Take
intermittant breaks and/or wear ear
protection from engine noise as well as
heavy work gloves to reduce vibration in
the hands.
II. Slope Operation
Slopes are a major factor related to slip and
fall accidents which can result in severe injury. All slopes require extra caution. If you feel
uneasy on a slope, do not trim it.
276798MA DRAFT COPY
Do trim across the face of slopes; never up
and down. Do not trim excessively steep
slopes (maximum 15 degrees) or areas
where the ground is very rough. Exercise extreme caution when changing direction on
slopes.
Do remove objects such as rocks, tree limbs,
etc.
Do watch for holes, ruts, or bumps. Tall grass
can hide obstacles.
Do not trim near drop−offs, ditches, or em-
bankments. The operator could lose footing
or balance.
Do not trim on wet grass. Reduced footing
could cause slipping.
III. Children
Tragic accidents can occur if the operator is
not alert to the presence of children. Children
are often attracted to the machine and the
trimming activity. Never assume that children
will remain where you last saw them.
1. Keep children out of the trimming area
and under the watchful care of a responsible adult.
2. Be alert and turn machine off if children
enter the area.
3. Before and while moving backwards,
look behind and down for small children.
4. Never allow children to operate the machine.
5. Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
IV. Service
1. Use extra care in handling petrol and
other fuels. They are flammable and vapors are explosive.
a. Use only an approved container.
b. Never remove gas cap or add fuel
with the engine running. Allow engine to cool before refueling. Do not
smoke.
c. Never refuel the machine indoors.
d. Never store the machine or fuel
container inside where there is an
open flame, such as a water heater.
e. If the fuel tank has to be drained,
this should be done outdoors. The
drained fuel should be stored in a
container specifically designed for
fuel storage or it should be dis-
5
posed of carefully.
2. Never run an engine indoors or inside a
SAFETY RULES
closed area.
3. Never make adjustments or repairs with
the engine running. Disconnect the
spark plug wire, and keep the wire away

TRIMMER TIPS
WARNING: Debris such as sticks,
gravel or stones, can be thrown
with sufficient force to cause personal injury or property damage.
S Set the throttle control in the FAST posi-
tion. If the weeds or grass are tall and
thick, operate the machine at a slower
walking speed.
S Frequently clean the underside of the ma-
chine to remove any grass build up.
S 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.
S If the trimmer lines become too short, it will
276798MA DRAFT COPY
take longer to complete the job. If the trimmer lines are worn to less than half their
original length, change to a new trimmer
line. “See How To Change The Trimmer
Line” in the Maintenance section.
S Do not trim on excessively steep slopes. If
a slope is difficult to stand on, do not trim.
Do not trim on slopes when the ground is
slippery or wet. Trim across the face of a
slope, not up and down.
SSTrimming may be done at slower engine
speeds especially when trimming around
flowers, shrubs, and small trees. Operating at slower speeds will also reduce engine noise and vibration at the upper
handle.

SERVICE AND ADJUSTMENT
WARNING: Before you inspect, clean or service the machine, stop the engine.
Make sure that all moving parts have stopped. Disconnect the wire from the
spark plug.
HOW TO REPLACE THE TRIMMER LINE
For the best performance, use a heavy
gauge 3.3mm (0.130” diameter) trimmer
line. Cut the length of the trimmer line to
52cm (21.5 inches). Do not allow the length
of the lines to vary more than one inch. This
is important to make sure the trimmer head
is balanced and does not vibrate.
HOW TO CHANGE TRIMMER LINES
When the trimmer line becomes worn to half the original length, replace the trimmer line as
follows:
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.
Line
Retainer
1. Stop the engine. Wait for
all moving parts to stop.
2. Remove worn trimmer
line from line retainer.
3. First, thread the ends of
the new trimmer line
through the outside
loops.
