SPARK ARRESTER WARNING TO RESIDENTS OF CALIFORNIA AND SEVERAL OTHER STATES
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 en-
gine 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 continu-
ous 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.
IMPORTANT

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 for-
eign objects being thrown by high-
speed rotating parts which can cause
personal injury or property damage.
Stay away from glass and other easily
thrown or breakable objects.
1. Keep children out of the mowing
area and under the watchful care of a
responsible adult.
They should never be in an awkward
position for the operator.
2. Be alert and turn machine off if chil-
dren enter the area.
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.
3. Before and while moving back-
wards, look behind and down for small
children.
4. Never allow children to operate the
machine.
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.
5. Use extra care near blind corners,
shrubs, trees, or other objects that
may obscure vision.
DO:
Mow across the face of slopes; never
up and down. Exercise extreme cau-
tion when changing direction on
slopes. Avoid slopes greater than
15o.
6. Never carry children, even with the
trimmer head stopped. Children may
fall off and be seriously injured or in-
terfere with safe machine operation.
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 Throt-
tle Control Lever and cable. Make sure
the cable is free and the lever functions
properly.
Remove objects such as rocks, tree
limbs, etc.
7. Do not allow children nearby if you
are working.
Uneven terrain could overturn the
machine. Watch for holes, ruts, or
bumps. Tall grass can hide obstacles.
24. Watch for traffic when near or
when crossing roadways.
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:
Use slow speed.
25. Never attempt to carry children or
other passengers on the equipment.
They could fall off and be seriously in-
jured, or they could interfere with safe
operation of the equipment.
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.
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.
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 situa-
tion is corrected.
Avoid starting or stopping on a
slope.
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.
27. Be aware of where the machine is
discharging materials and do not point
the discharge at anyone.
DO NOT:
e) Replace caps on the fuel tank
and fuel container and clean up
spilled fuel before starting en-
gine. Move machine away from
any gasoline fumes before start-
ing the engine.
Do not mow near drop-offs, ditches,
or embankments. You could lose
footing or balance.
28. Never run the engine in an en-
closed 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.
Do not mow on very steep slopes.
Do not mow on wet grass. Slippery
footing can be hazardous.
f) Keep matches, smoking materi-
als, open flames, and sparks
away from the fuel tank and fuel
container.
Children
29. Slow down before turning.
30. Shut off engine when not trimming
or mowing.
Tragic accidents can occur if the opera-
tor is not alert to the presence of chil-
dren. Children are often attracted to the
machine and the mowing activity.
Never assume that children will remain
where you last saw them.
g) Leave 1/2" air space at the top of
the fuel tank to allow for fuel ex-
pansion.
31. Use extra care when loading or un-
loading 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.

and debris shield. Make sure they are
not bent, damaged, or loose.
16. Remember – the end of the sea-
son is a good time to inspect equip-
ment prior to storage.
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.
10. Only use eighteen-inch long .130"
or .155" diameter trimmer line. Never
use other lengths, diameters or material
as trimmer line.
17. To guard against engine overheat-
ing, always keep the engine debris
guard mounted and clean.
11. Trimmer line moves
at high speed and can
cut. Always stop the
engine and let all mov-
ing parts stop before
replacing the trimmer lines. Let the
engine cool.
18. For units equipped with electric
start:
4. Keep all nuts and bolts tight, espe-
cially 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.
a) Batteries produce explosive
gases. Keep sparks, flame,
cigarettes, etc., away. Ventilate
area when charging battery. Do
not charge battery in an airtight
space.
12. Do not change the engine gover-
nor setting or overspeed the engine.
The governor controls maximum safe
operating speed and protects the en-
gine and all moving parts from dam-
age caused by overspeed. Authorized
service shall be sought if a problem
exists.
b) Do not use a battery charger
other than the one provided with
the unit.
5. Never tamper with safety devices.

parts to cool completely before in-
specting, cleaning or repairing the unit.
7. After striking an object, stop the
engine and disconnect the spark plug
wire. Inspect the machine and repair, if
necessary, before restarting.
d) Properly dispose of a damaged
or worn out battery. Check with
local authorities for proper dis-
posal methods.
14. Maintain or replace safety and in-
structional decals. Refer to the Parts
List for replacement decal information.
8. Never make adjustments or repairs
while engine is running.
e) Do not short circuit the battery.
Severe burns and fire can
result.
9. Components subject to wear,
damage and deterioration could ex-
pose moving parts or allow objects to
be thrown. Frequently check compo-
nents and replace with factory recom-
mended parts, when necessary.
15. Use only original-equipment
replacement parts. Parts manufac-
tured by others could present safety
hazards and affect performance even
though they may fit on this machine.
Regularly inspect the trimmer head

INTRODUCTION
Follow gasoline safety rules in this
Manual (see Section 1) and in the
separate Engine Owner’s Manual.
Read this Section thoroughly before
you start the engine. As with any piece
of outdoor power equipment, getting
the “feel” for how your machine oper-
ates and knowing the best techniques
for particular jobs are important to
overall good performance.
Failure to follow gasoline safety rules
and instructions can result in serious
personal injury and property damage.
In general, use higher height settings
to handle taller material and to cope
with tougher cutting conditions. For
less demanding situations, use any
trimming height desired. To adjust the
cutting height:
1. Lift and tilt plastic debris shield (E,
Figure 3-1) forward.
NOTE: All references to LEFT, RIGHT,
FRONT and REAR of the machine are
determined by standing in the opera-
tor’s position.
2. Clean fuel fill area and engine debris
guard each time before fuel is added.
3. Fill the fuel tank with gasoline ac-
cording to the directions in the sepa-
rate Engine Owner’s Manual. Follow all
instructions and safety rules carefully.

To Start the Trimmer Head
1. Stand in the operator’s position
directly behind the handlebars.
USING THE TRIMMER HEAD
CONTROL BAIL
Before starting the engine, it is essen-
tial to know how to use the Trimmer
Head Control Bail.
Adjust or repair the control bail
before using the trimmer/mower.
2. Slowly close the Trimmer Head
Control Bail (Figure 4-4) against the
handlebars to activate the trimmer
head. Use the Engine Throttle Lever to
adjust the turning speed of the trimmer
head.
Failure to follow this instruction could
result in personal injury or property
damage.
1. The Trimmer Head Control Bail (A,
Figure 4-3) is used to start and stop
trimmer head motion.
3. Once the trimmer head is revolving,
push the trimmer/mower along the
path to be cut.
OPERATING THE
TRIMMER/MOWER
Once you have read and understood
the sections in this Manual on Safety,
Assembly, Features and Controls, and
Operation, you are ready to start and
operate your trimmer/mower.
2. Leave the control bail in the disen-
gaged (released) position when start-
ing the engine to prevent the trimmer
head from turning when the engine
starts. See Figure 4-3.
To Stop the Trimmer Head
Let go of the Trimmer Head Control Bail.
It will return to its open position and
the trimmer head will stop turning.
3. When the engine is running, pull up
and hold the control bail against the
handlebar (Figure 4-4) to start rotation
of the trimmer head.
Checklist Before Starting
To Stop the Engine
1. Complete the Pre-Start Checklist in
this Section of the Manual. You must
wear safety glasses or goggles.
Put the Engine Throttle Control Lever in
the STOP position. (If time allows, first
move throttle lever to SLOW setting
before stopping engine.)
4. Let go of the control bail to stop the
trimmer head. The control bail should
spring forward to the disengaged posi-
tion. If it doesn’t, do not use the ma-
chine until the control bail has been
repaired.
2. Check that the line cutting height is
adjusted according to the instructions.

Section 4: Operation
Clean the Trimmer/Mower
On a Regular Basis
Clean under the mower deck frequently
to remove any grass buildup. Also
clean around the muffler and on top of
engine. See the cleaning instructions
in Section 5: Maintenance.
Vary the Throttle Setting
According to Conditions
The majority of trimming and mowing
jobs will yield the best results if the
Engine Throttle Control is set at the
fastest engine speed.
WARNING
THROWN OBJECT HAZARD
• Objects such as rocks, pebbles,
and small debris will be thrown
violently by the cutting head,
resulting in significant hazard to
eyes and exposed body parts.
Less demanding jobs that require very
precise cutting will yield better results
if the engine throttle is backed off
somewhat to reduce engine speed.
(For example, damage to trees and or-
namentals can be avoided by reducing
the engine speed; using the lighter
.130" diameter line; and by keeping a
safe distance away.)
Do Not Let the Trimmer
Lines Become Too Short
• Always wear safety-approved eye
protection and suitable clothing
and footwear.
Once the trimmer lines are worn to less
than 1/2 their original length, trimming
jobs begin to take far longer than they
should.
• Keep children, pets and bystanders
50 feet away from machine while
operating.
• Be alert to hidden obstacles.
As a general guideline, once the line
length becomes half of its original
length, it’s time to change to new lines.
Again, once you begin a particular job
and get a “feel” for the conditions, you
will be able to make adjustments for
the best possible results.
Failure to comply could result in
injury or property damage.
Use Extreme Caution on Slopes
When operating on sloping ground,
use extreme caution and common
sense to avoid possible injury or prop-
erty damage.
Keep the Mowed Side to Your
Right as You Move Ahead
ADDITIONAL OPERATING TIPS
AND TECHNIQUES
The trimmer/mower feeds cut materials
to the right side. Stay on the right side
of unmowed growth as you move
along.
Tips for Precision Cutting
Do not mow on excessively steep
For the most precise cutting possible,
be sure to select the appropriate line
cutting height and trimmer line size
(thickness) for the conditions at hand.
slopes! Avoid slopes if greater than
150 or wherever footing is unsure. If a
slope is difficult to stand on, it is prob-
ably too steep to trim or mow. In this
case, it may be wiser to establish a per-
manent ground cover on this area.
NOTE: If the trimmer is operated in
a stationary position with the wear
cup in contact with dry vegetation,
significant heat will result that may
deform the plastic spindle or scorch
vegetation.
When mowing, let the cutting head rest
lightly on the ground and do not lift up
on the handlebars. This allows the cut-
ting head to follow the ground contour
closely, resulting in the most even cut
possible. Also, be sure to ease into
heavy growth to prevent overwhelming
the machine.
Do not trim on slopes when the ground
is slippery. Trim across the face of a
slope, not up and down. Slow down
and exercise caution when changing
direction on slopes.
Use Correct Walking Speed
Trim When Wet or Dry
Use a walking speed that is suitable for
the conditions at hand. For example,
you’ll get better trimming and mowing
results at slower walking speeds if the
grass is tall or lush. Shorter grass or
less dense growth can be cut at faster
travel speeds.
Grass and most other materials are
most efficiently trimmed when dry.
But, the trimmer/mower will do a fine
job even with damp or wet materials.
When conditions are moist or damp, be
sure to clean debris off the machine
regularly to keep cutting efficiency
high. And watch your footing!

WARNING
Before inspecting, cleaning or servicing the machine, shut off engine, discon-
nect spark plug wire, and make sure that all moving parts have come to a com-
plete stop. Remove ignition key on electric start models.
The tension on the drive belt must be
correct for proper operation of the
trimmer head. If the tension is correct,
the trimmer head will rotate when the
Trimmer Head Control Bail is pulled
back against the handlebar (another in-
dication of correct tension is if the
engine stalls when the trimmer head
becomes bound up in very tough
material.)
Failure to follow these instructions can result in personal injury or property
damage.
NOTE: LEFT and RIGHT sides of unit are as viewed
from operator’s position behind the handlebars.
A worn or loose drive belt will slip on
its pulleys, causing the trimmer head
to move slowly, or not at all, when the
control bail is engaged (belt squealing
may also be noticeable).

TRIMMER/MOWER CLEANING
AND DEBRIS REMOVAL
WARNING
Never run engine without debris
guard properly installed. If debris
guard is not properly installed, grass
clippings may be drawn into engine,
causing heat buildup and, in some
cases, a fire.
Change the oil after every 25 hours of
operation and even sooner when
operating in extremely dirty or dusty
conditions.
Thorough and regular cleaning of de-
bris from around the engine and on the
machine is required for maximum
engine efficiency and good overall
performance. Inspect and clean the
following areas regularly, making sure
the engine is stopped, and cool, before
proceeding:
Air Cleaner Service
The engine air cleaner filters dirt and
dust out of the air before it enters the
carburetor. Operating the engine with a
dirty, clogged air filter can cause poor
performance and damage to the en-
gine. Never operate the engine without
the air cleaner installed. Inspect and
service the air cleaner after every 25
operating hours, more often if operat-
ing in very dusty or dirty conditions.
Refer to the Engine Owner’s Manual for
cleaning or replacement instructions.
Failure to comply can cause injury or
property damage.
• Brush and wipe off all engine sur-
faces, especially before checking oil
or adding fuel. Do not let oil or
grease accumulate. For access to the
front of the engine, the debris shield
can be lifted up and tilted forward.
LUBRICATION
Applying light oil or a silicone-based
lubricant to your machine allows parts
to work more smoothly and protects
them from the elements. The following
are general guidelines:
• Wipe the deck clean, particularly near
the engine muffler.
Silicone-base Spray Lubricant
(or light oil):
• Clean the underside of the deck.
Spark Plug Service
• Keep safety and operating decals
Inspect and clean or replace the spark
plug after every 100 operating hours or
annually. Refer to the Engine Owner’s
Manual for cleaning or replacement

• Throttle control cable
• Control bail cable
• Nuts, bolts and other hardware
• Keep all operating control levers
debris-free so they work properly.
NOTE: The spindle head is perma-
nently lubricated at the factory. There
is no need for additional lubrication.
CLEANING THE ENGINE
DEBRIS GUARD
Spark Arrester Screen Service
If the engine is equipped with a spark
arrester screen, remove and clean it
according to the time intervals and
instructions in the Engine Owner’s
Manual.
It is extremely important to keep the
engine debris guard (A, Figure 5-7)
free of dirt and debris so the engine
can run as efficiently and as cool as
possible.
COMPACT STORAGE
For compact storage of the unit, re-
move the two screws and locknuts se-
curing the handlebar and carefully (to
avoid kinking the cables) rotate the
handlebar so that the upper portion
rests on the engine and the handlebar
legs face to the rear of the unit.
Engine Cleaning
Brush the debris guard clean before
using the unit each time and whenever
you see a build-up of dirt and debris.
The engine must be kept clean to as-
sure smooth operation and to prevent
damage from overheating. Refer to the
Engine Owner’s Manual for specific
cleaning instructions.
NOTE: The separate engine air cleaner
must also be serviced according to the
instructions in the Engine Owner’s
Manual.

WARNING
Failure to follow these instructions can result in serious personal injury or property damage.
4. Simply feed the line through the
CHANGING TRIMMER LINES
WARNING
loops of the line holder as shown. An
equal amount of line should project out
from each side of the line holder, creat-
ing an overall 22" wide cutting swath.
You may offset both trimmer lines
somewhat to increase the cutting
swath up to 25" wide. However, DO
NOT offset the line so that the overall
cutting swath is greater than 25". See
Warning statement at right.
The trimmer lines will wear with use
and eventually require replacement.
Also, you may wish to switch between
the thinner and thicker gauge lines to
handle different mowing conditions.
Offsetting the trimmer lines causes
the lines to rotate faster than when
they project an equal length on each
side. This increases the chance of
loose materials being dislodged and
propelled at high speeds.
Replace the trimmer lines when they
wear to the point that trimming and
mowing projects take too long and
require too much maneuvering of the
machine. A good rule of thumb is to
change the lines when they reach half
their original length.
Failure of the operator to wear safety
goggles and appropriate clothing and
to keep bystanders away can result in
severe personal injury or property
damage.
IMPORTANT: Whether replacing one
or both lines, they must both be .130"
or .155" in diameter.
Use the extra-heavy duty gauge (.155"
diameter) line when cutting thick,
tough growth. The thinner gauge
(.130" diameter) line is for use in less
demanding conditions, and is also rec-
ommended for use near trees or orna-
mentals to help prevent girdling (cut-
ting of bark).
5. Repeat steps 2 through 4 to replace
the second trimmer line.
Figure 5-10: Use this sin-
gle line, easy-loop pattern
for all but the more difficult
cutting conditions.
To Change Trimmer Lines:
1. Stop engine, allow all parts to stop
moving and then disconnect the spark
plug wire. Remove the ignition key on
electric start models. DO NOT tip the
machine. DO NOT touch the metal
wear cup on the bottom of the spindle
head. This surface may be hot.
Reverse Loop
Figure 5-11: If the lines
should loosen while trim-
ming (especially in more
difficult conditions), add a
simple reverse loop. Note
that this pattern will result
in a slightly narrower over-
all cutting swath.
NOTE: The two line holders on the
trimmer head are permanently secured
by a screw and a nut. Do not attempt
to remove the line holders as it is not
necessary to remove them in order to
change the trimmer lines.
2. The trimmer lines can be changed
when the trimmer head is in contact
with the ground. If necessary, you
may tip the unit back slightly for a bet-
ter view. However, do not tip the unit
all the way back or motor oil may flow
to the exhaust area and the engine may
smoke for several seconds when
started.
Figure 5-12: For more diffi-
cult cutting conditions, use
two of the thicker gauge
(.155" diameter) lines in
each line holder. Follow
the installation pattern
shown in Figure 5-10.
3. Three different line installation pat-
terns are available, as shown in Figures
5-10, 5-11 and 5-12.
