erators carefully follow the recommended safety practices at all times. Failure to do so could result in personal injury or property damage.
Of course, if you should ever have any problems or
questions, please contact your local authorized service
dealer or call the Factory.
We want to be sure that you are completely satisfied

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.

Section
Safety
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.
SPARK ARRESTER WARNING TO RESIDENTS OF CALIFORNIA AND SEVERAL OTHER STATES
I. General Operation
IMPORTANT
Safe Operation Practices for Walk-Behind Mowers
This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe the
following safety instructions could result in serious injury or death.
1. Read, understand, and follow all
instructions on the machine and in the
manuals. Be thoroughly familiar with
the controls and the proper use of the
equipment before starting.
2. Do not put
hands or feet near or
under rotating parts.
Keep clear of the rotating trimmer head
and line at all times.
3. Only allow responsible adults,
who are familiar with the instructions,
to operate the trimmer/mower. Never
let children or untrained adults operate this equipment.
4. Inspect the area where the trimmer/mower is to be used. The equipment can propel small objects at high
speed, causing personal injury or
property damage. Clear the area of objects such as rocks, toys, wire, bones,
sticks, etc., which could be picked up
and thrown by the trimmer line.
5. Be sure the area is clear of other
people (particularly small children and
pets) before mowing. Stop trimmer/
mower if anyone enters the area.
Keep bystanders at least 50 feet from
the area of operation.
6. Do not operate the trimmer/
mower 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
accessories.
12. Stop trimmer head when crossing
gravel drives, walks, or roads. Wait for
trimmer lines to stop.
13. Stop engine and disconnect spark plug wire from
spark plug whenever you
leave the unit, clean
the equipment, or
replace trimmer line.
Remove the key on electric start
models.
14. Wait until the trimmer head comes
to a complete stop, shut the engine off,
and disconnect the spark plug wire before installing or removing trimmer
line. Be sure trimmer head is securely
attached before operating equipment.
15. Mow only during daylight hours or
when good artificial light is available.
16. Do not operate the trimmer/
mower while under the influence of alcohol or drugs, or when tired or ill.
17. Never operate this equipment in
wet grass. Be sure of your footing; keep
a firm hold on the handlebar and walk;
never run.
18. Release trimmer head control bail
before starting engine.
19. If the unit starts to vibrate abnormally, stop the engine and disconnect
the spark plug wire. Check immediately for the cause. Vibration is generally a warning of trouble.

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 (if so
equipped). 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 mower 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 trimmer/
mower 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.
II. 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.
III. Children
Tragic accidents can occur if the operator is not alert to the presence of
children. Children are often attracted
to the trimmer/ mower and the mowing activity. Never assume that children will remain where you last saw
them.
MA
IS
•
•
•
1. Keep children out of the mowing
area and under the watchful care
of a responsible adult.
2. Be alert and turn trimmer/moweroff
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
mower.
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.
IV. 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 con-
tainer.
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 ma-
terials, 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 separate Parts Catalog for replacement
decal information.
15. For units equipped with electric
start:
a) Batteries produce explosive
gases. Keep sparks, flame,
2. Never run the engine inside a
closed area.
3. Never clean, 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 trimmer/mower 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
cigarettes, etc., away. Ventilate the area when charging
the battery. Do not charge the
battery in an airtight space.
b) Do not use a battery charger
other than the one provided to
you.
c) The battery contains toxic ma-
terials. Do not damage the
battery case. If the case is broken or damaged, avoid contact
with the battery contents.
d) Properly dispose of a dam-
aged or worn out battery.
Check with local authorities
for proper disposal methods.
e) Do not short circuit the bat-
tery. Severe burns and fire can
result.
16. Use only original-equipment re-
placement parts. Parts manufactured
by others could present safety hazards
and affect performance even though
they may fit on this trimmer/mower.
17. Remember– the end of the season
is a good time to inspect equipment
prior to storage.
18. To guard against engine overheat-
ing, always have the engine debris filter
mounted and clean.
Safety Decals
Make certain that all safety decals on this equipment
are kept clean and in good condition. The decals are

Section
Assembly
Introduction
Carefully follow these assembly steps
to correctly prepare your machine for
use. It is recommended that you read
this section in its entirety before beginning assembly.
NOTE: If an assembly step applies only
to certain models, those models are
noted at the beginning of that step.
Otherwise, a step applies to all models.
Inspection After Delivery
Inspect your machine immediately after
it has been delivered. Make sure that
neither the carton nor the contents
have been damaged.
If you find or suspect any damage,
contact the carrier (trucking company)
right away. Inform them of the specific
damage and that you wish to file a
claim. To protect your rights, be sure
to put this in writing to the carrier
within 15 days after your machine arrives. Please let us know if you need
assistance with this matter.
IMPORTANT: Motor oil must be
added to the engine before starting.
The correct procedure for adding
motor oil is explained in this Section.
STEP 1: Unpack, Check Contents
Remove and discard all protective
packaging material (plastic film and
cardboard) from the handlebars and
the machine. Be sure to remove the
handlebars from the insert and carefully (do not crimp the attached cable)
put them aside before removing the
unit from the bottom of the packaging.
Then compare the parts inside the
shipping carton with the following list
(items with an asterisk [*] are packaged separately within the carton).
All Models:
• Trimmer/Mower Assembly
(A, Fig. 2-1 )
• Extra Trimmer Line - 6 pieces of
green, heavy-duty .130" diameter and
6 pieces of red, extra-heavy-duty
.155" diameter (B, Fig. 2-1).
• Safety goggles* (not shown)
• One plastic cable tie * (not shown)
• Two Hex Hd. Screws *, 5/16-18 x 2
(not shown)
• Two Locknuts *, 5/16-18 (not shown)
Electric Start Model Only:
• Battery (on unit, C, Figure 2-1).
• *Two ignition keys
• *One battery recharger
STEP 2: Install Handlebars
NOTE: Do not pinch any cables while
unfolding and securing the handlebars.
IMPORTANT: Adjust the handlebars
as close as possible to waist level so
arms are at a comfortable height.
This lessens pressure on the mower
wear cup, making the unit easier to
roll and reducing wear on the wear cup.
A. Cut the plastic tie and remove the
tape that secures the control bail (G,
Fig. 2-2) to the handlebar (A).
B. Using care not to pinch the attached
cable, lift the handlebars (A, Fig. 2-2)
to rear of the unit and align the handlebar ends with the handlebar support (B).
C. Route the cable (C, Fig. 2-2) to the
outside of the handlebars.
D. Select either the low or high height
setting holes (most people prefer the
low setting) in the handlebar legs and
attach the handlebars with the two
screws (D) and locknuts (E) from the
hardware bag. Use two 1/2" wrenches.
E. Use the cable tie (F, Fig. 2-2) from
the hardware bag to secure cable (C) to
handlebar at the location shown.
WARNING
To prevent personal injury or
property damage, do not attempt to start the engine until
all assembly steps are complete and you have read and
understand all of the safety and
the operating instructions in
this Manual.
Tools/Supplies Needed:
• One Utility Knife or Scissors
• Two 1/2" wrenches
• SAE 30 weight motor oil
• Unleaded gasoline

Section 2:Assembly
STEP 3: Add Motor Oil
A. The unit’s engine was shipped
without motor oil which MUST BE
ADDED before the engine is started.
B. See the Engine Owner’s Manual you
received for filling instructions and for
the correct oil specifications for your
engine. Engine must be level when
checking oil level. In ambient temperatures above 400 F, use a high-quality
SAE 30 weight detergent oil classified
for Service SF, SG or SH. Use no special additives. Do not mix oil with fuel.
C. Lift or slide plastic debris shield (P,
Figure 2-3) up and tilt it forward to access engine dipstick/oil fill hole (R).
D. Add oil according to the instructions in the Engine Owner’s Manual.
E. Lift and tilt the plastic debris shield
back and push it down to secure it.
STEP 4: Connect Battery
Wires and Charge Battery
(electric start model only)
A. Connect wire lead (T, Fig. 2-4) from
the battery (S) to the connector (U) on
the main wire harness. Align connectors so wire colors are in line. Press
both plastic connectors together
securely.
B. To charge the battery, the battery
charger shipped to you must first be
connected to the wire harness at location “V” (Fig. 2- 5). Then plug the
charger box (W, Fig. 2-5) into a
grounded 120V wall outlet.
C. Initially charge battery for 24 hours
before using electric starter. After
charging, unplug the charger from the
wall outlet first, then disconnect the
wire harness (V, Fig. 2-5). (Prior to
and after removing machine from winter storage, also charge battery for 24
hours.)
STEP 5: Check Trimmer
Head Hardware
Check the tightness of the hardware
securing the trimmer head at two locations (X, Figure 2-6) and the hardware
that secures the line clamps at two locations (Y). You may rotate the trimmer head by hand to make access to
the hardware easier. Tighten the hardware securely.
NOTE: The small round hole on the top
of the deck near the front of the machine is a service entryway. Its use is
explained in “Section 5: Maintenance.”
IMPORTANT: The trimmer head hardware is designed to be permanently
installed and is not removable. Do
not attempt to replace it with non-factory specified hardware.
