WARNING
The engine exhaust from this product contains
chemicals known to the state of California to
cause cancer, birth defects, or other reproductive harm.
Safety Alert Symbol
This is a safety alert symbol. It is used in this
manual and on the unit to alert you to potential
hazards. When you see this symbol, read and
obey the message that follows it. Failure to
obey safety messages could result in personal injury or
property damage.
1
Under California law, and under the laws of several other states, you are not permitted to operate an
internal combustion engine using hydrocarbon fuels on any forest covered, brush covered, or grass
covered land, or on land covered with grain, hay, or other flammable agricultural crop, without an engine spark arrestor in continuous effective working order.
The engine on your power equipment, like most outdoor power equipment, is an internal combustion engine that burns
gasoline, a hydrocarbon fuel. Therefore, your power equipment must be equipped with a spark arrestor muffler in continuous effective working order. The spark arrester must be attached to the engine exhaust system in such a manner that flames
or heat from the system will not ignite flammable material. Failure of the owner/operator of the equipment to comply with
this regulation is a misdemeanor under California law, and may also be a violation of other state and/or federal regulations,
laws, ordinances, or codes. Contact your local fire marshal or forest service for specific information about what regulations
apply in your area.

people (particularly small children and
pets) before mowing. Stop machine if
anyone enters the area. Keep bystanders at least 50 feet from the area
of operation.
6. Do not operate the machine when
barefoot or wearing open sandals.
Always wear substantial footwear.
7. Wear appropriate clothing such as
a long-sleeved shirt or jacket. Also
wear long trousers or slacks. Do not
wear shorts.
8. Do not wear loose clothing– it
could catch in the equipment.
9. Do not mow in reverse unless
absolutely necessary. Always look
down and behind before and while
moving backwards.
10. Do not operate the trimmer/mower
without proper guards, plates, or other
protective safety devices in place.
11. Refer to provided instructions for
proper operation and installation of accessories. Only use factory-approved

Section 1: Safety
20. Always wear approved safety gog-
gles or safety glasses with side shields
when operating equipment. The use of
any powered machine can result in foreign objects being thrown by highspeed rotating parts which can cause
personal injury or property damage.
Stay away from glass and other easily
thrown or breakable objects.
21. Wear work gloves and sturdy
footwear when using this equipment.
Leather work shoes or short boots are
ideal. They protect ankles and shins
from rocks, pebbles, splinters, etc.
22. It is advisable to wear protective
headgear to prevent the possibility of
being hit by small flying particles, etc.
23. Before each use, inspect the Throttle Control Lever and cable. Make sure
the cable is free and the lever functions
properly.
24. Watch for traffic when near or
when crossing roadways.
25. Never attempt to carry children or
other passengers on the equipment.
They could fall off and be seriously injured, or they could interfere with safe
operation of the equipment.
26. The machine is equipped with a
plastic debris shield in front of the
engine and a rubber debris flap under
the frame. They must be in place and
working properly. Never remove or
cause the debris shield or debris flap to
cease working. If either of these parts
is missing or not working properly, do
not use the equipment until this situation is corrected.
27. Be aware of where the machine is
discharging materials and do not point
the discharge at anyone.
28. Never run the engine in an enclosed area. Engine exhaust contains
carbon monoxide, a deadly gas that is
odorless, colorless and tasteless.
Always run the engine outdoors where
there is adequate ventilation.
29. Slow down before turning.
30. Shut off engine when not trimming
or mowing.
31. Use extra care when loading or unloading machine into a trailer or truck.
32. Use this equipment for its intended
purpose only.
33. Always make sure the handlebars
are tight and comfortably positioned.
They should never be in an awkward
position for the operator.
Slope Operation
Slopes are a major factor related to
loss of control and tip-over accidents
which can result in severe injury or
death. All slopes require extra caution.
If you can not back up the slope or you
feel uneasy on a slope, do not mow it.
DO:
Mow across the face of slopes; never
up and down. Exercise extreme caution when changing direction on
slopes. Avoid slopes greater than
15o.
Remove objects such as rocks, tree
limbs, etc.
Uneven terrain could overturn the
machine. Watch for holes, ruts, or
bumps. Tall grass can hide obstacles.
Use slow speed.
Use extra care with grass catchers or
other attachments. These can
change the stability of the machine.
Keep all movement on the slopes
slow and gradual.
Avoid starting or stopping on a
slope.
DO NOT:
Do not mow near drop-offs, ditches,
or embankments. You could lose
footing or balance.
Do not mow on very steep slopes.
Do not mow on wet grass. Slippery
footing can be hazardous.
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 mowing activity.
Never assume that children will remain
where you last saw them.
1. Keep children out of the mowing
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 near blind corners,
shrubs, trees, or other objects that
may obscure vision.
6. Never carry children, even with the
trimmer head stopped. Children may
fall off and be seriously injured or interfere with safe machine operation.
7. Do not allow children nearby if you
are working.
Service
1. Use extra care in handling gasoline
and other fuels. They are flammable
and their vapors are explosive. To
help prevent a fire or explosion:
a) Use only an approved container.
b) Never remove gas cap or add
fuel when the engine is running.
Let engine cool before refueling.
Do not smoke.
c) Never refuel the machine in-
doors. Fill the fuel tank outdoors
and with extreme care.
d) Never store the machine or fuel
container inside where there is
an open flame, such as a water
heater, etc.
e) Replace caps on the fuel tank
and fuel container and clean up
spilled fuel before starting engine. Move machine away from
any gasoline fumes before starting the engine.
f) Keep matches, smoking materi-
als, open flames, and sparks
away from the fuel tank and fuel
container.
g) Leave 1/2" air space at the top of
the fuel tank to allow for fuel expansion.

Section 1: Safety
and debris shield. Make sure they are
not bent, damaged, or loose.
10. Only use eighteen-inch long .130"
or .155" diameter trimmer line. Never
use other lengths, diameters or material
as trimmer line.
11. Trimmer line moves
at high speed and can
cut. Always stop the
engine and let all moving parts stop before
replacing the trimmer lines. Let the
engine cool.
12. Do not change the engine governor setting or overspeed the engine.
The governor controls maximum safe
operating speed and protects the engine and all moving parts from damage caused by overspeed. Authorized
service shall be sought if a problem
exists.
13. Do not touch engine parts which
may be hot from operation. Allow
parts to cool completely before inspecting, cleaning or repairing the unit.
14. Maintain or replace safety and instructional decals. Refer to the Parts
List for replacement decal information.
15. Use only original-equipment
replacement parts. Parts manufactured by others could present safety
hazards and affect performance even
though they may fit on this machine.
2. Never run the engine inside a
closed area.
3. Never clean, or make adjustments
or repairs with the engine running.
Disconnect the spark plug wire and
keep the wire away from the plug to
prevent accidental starting. Remove
key on electric start models.
4. Keep all nuts and bolts tight, especially the trimmer head attachment
bolts, and keep equipment in good
condition. Check mounting hardware
on trimmer head every time you
change trimmer line and prior to each
use.
5. Never tamper with safety devices.
Check their proper operation regularly.
6. To reduce fire hazard, keep mower
free of grass, leaves or other debris
build-up. Clean up oil or fuel spills. Let
machine cool before storing.
7. After striking an object, stop the
engine and disconnect the spark plug
wire. Inspect the machine and repair, if
necessary, before restarting.
8. Never make adjustments or repairs
while engine is running.
9. Components subject to wear,
damage and deterioration could expose moving parts or allow objects to
be thrown. Frequently check components and replace with factory recommended parts, when necessary.
Regularly inspect the trimmer head
16. Remember – the end of the sea-
son is a good time to inspect equipment prior to storage.
17. To guard against engine overheating, always keep the engine debris
guard mounted and clean.
18. For units equipped with electric
start:
a) Batteries produce explosive
gases. Keep sparks, flame,
cigarettes, etc., away. Ventilate
area when charging battery. Do
not charge battery in an airtight
space.
b) Do not use a battery charger
other than the one provided with
the unit.
c) The battery contains toxic mate-
rials. Do not damage the battery
case. If the case is broken or
damaged, avoid contact with the
battery contents.
