SPARK ARRESTER WARNING TO RESIDENTS
Engine Throttle Control Lever
OF CALIFORNIA AND SEVERAL OTHER STATES
Handlebar
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, brush, hay, grain, or grass covered land; or land
covered by any flammable agricultural crop without an
engine spark arrester in continuous effective working
order.
Keyswitch (electric
start model)
Engine Recoil
Starter
Plastic Debris
Shield
Fuel Primer
The engine on the unit is an internal combustion engine
which burns gasoline, a hydrocarbon fuel, and must be
equipped with a spark arrester 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
unit to comply with this regulation is a misdemeanor
under California law (and other states) and may also be
a violation of other state and/or federal regulations,
laws, ordinances or codes. Contact your local fire mar-
shal or forest service for specific information about
which regulations apply in your area.

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.
5. Be sure the area is clear of other
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.
10. Do not operate the trimmer/mower
without proper guards, plates, or other
protective safety devices in place.
General Operation
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 equip-
ment before starting.
11. Refer to provided instructions for
proper operation and installation of
accessories. Only use factory-approved
accessories.
2. Do not put hands or
feet near or under rotating
parts. Keep clear of the
rotating trimmer head and
line at all times.
12. Stop trimmer head when crossing
gravel drives, walks, or roads. Wait for
trimmer lines to stop.
6. Do not operate the machine when
barefoot or wearing open sandals. Always
wear substantial footwear.
13. Stop engine and disconnect
spark plug wire from spark plug
whenever you leave the unit,
clean the unit, or replace
trimmer line. Remove key
on electric start model.
3. Only allow responsible adults, who
are familiar with the instructions, to oper-
ate the trimmer/mower. Never let children
or untrained adults operate this unit.
7. Wear appropriate clothing such as a
long-sleeved shirt or jacket and long
trousers or slacks. Do not wear shorts.
4. Inspect the area where the machine is
to be used. The machine can propel small
objects at high speed, causing personal
injury or property damage. Clear the area
of objects such as rocks, toys, wire,
8. Do not wear loose clothing—it could
catch in the equipment.
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 the trimmer head is securely attached
before operating the machine.
9. Do not mow in reverse unless abso-
lutely necessary. Always look down and

monoxide, a deadly gas that is odorless,
colorless and tasteless. Always run the
engine outdoors where there is adequate
ventilation.
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.
16. Do not operate the machine while
under the influence of alcohol or drugs, or
when tired or ill.
29. Slow down before turning.
30. Shut off engine when not trimming or
mowing.
17. Never operate this machine in wet
grass. Be sure of your footing; keep a firm
hold on the handlebar and walk; never run. 31. Use extra care when loading or

unloading machine into a trailer or truck.
18. Release the Trimmer Head Control
Bail before starting the engine.
32. Use this equipment for its intended
purpose only.
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.
2. Be alert and turn machine off if children
enter the area.
33. Always make sure the handlebars are
tight and comfortably positioned. They
should never be in an awkward position
for the operator.
3. Before and while moving backwards,
look behind and down for small children.
4. Never allow children to operate the
20. Always wear approved safety goggles
or safety glasses with side shields when
operating machine. The use of any pow-
ered machine can result in foreign objects
being thrown by high speed rotating parts
which can cause personal injury or prop-
erty damage. Stay away from glass and
other easily thrown or breakable objects.
machine.
Slope Operation
5. Use extra care near blind corners,
shrubs, trees or other objects that may
obscure vision.
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.
6. Never carry children, even with the
trimmer head stopped. Children may fall
off and be seriously injured or interfere
with safe machine operation.
21. Wear work gloves and sturdy footwear
when using this machine. Leather work
shoes or short boots are ideal—they pro-
tect ankles and shins from rocks, pebbles,
splinters, etc.
DO:
7. Do not allow children nearby if you are
working.
Mow across the face of slopes; never up
and down. Exercise extreme caution
when changing direction on slopes.
Avoid slopes greater than 15o.
Service
22. It is advisable to wear protective
headgear to prevent the possibility of
being hit by small flying particles, etc.
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:
Remove objects such as rocks, tree
limbs, etc.
23. Before each use, inspect the Throttle
Control Lever and its cable. Make sure the
cable is free and that the lever functions
properly.
Uneven terrain could overturn the
machine. Watch for holes, ruts, or
bumps. Tall grass can hide obstacles.
a) Use only an approved container.
b) Never remove gas cap or add fuel
when engine is running. Let engine
cool before refueling. Do not smoke.
Use slow speed.
24. Watch for traffic when near or when
crossing roadways.
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 grad-
ual.
c) Never refuel the machine indoors.
Fill the fuel tank outdoors and with
extreme care.
25. Never attempt to carry children or
other passengers on the machine. They
could fall off and be seriously injured, or
they could interfere with safe operation of
the machine.
d) Never store the machine or fuel
container inside where there is an
open flame, such as a water heater,
etc.
Avoid starting or stopping on a slope.
26. The machine is equipped with a plas-
tic 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 machine until this
situation is corrected.
e) Replace caps on fuel tank and fuel
container and clean up spilled fuel
before starting engine. Move
machine away from any gasoline
fumes before starting engine.
DO NOT:
f) Keep matches, smoking materials,
open flames, and sparks away from
the fuel tank and fuel container.
Do not mow near drop-offs, ditches, or
embankments. You could lose your
footing or balance.
27. Be aware of where the machine is dis-
charging materials and do not point the
discharge at anyone.

c) The battery contains toxic materi-
als. Do not damage the battery
case. If the case is broken or dam-
aged, avoid contact with the battery
contents.
5. Never tamper with safety devices.
Check their proper operation regularly.
6. To reduce fire hazard, keep machine
free of grass, leaves or other debris build-
up. Clean up oil or fuel spills. Let
machine cool before storing.
d) Properly dispose of a damaged or
worn battery. Check with local
authorities for proper disposal.
13. Do not touch engine parts which may
be hot from operation. Allow parts to cool
completely before inspecting, 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 neces-
sary, before restarting.
e) Do not short circuit the battery.
14. Maintain or replace safety and instruc-
tional decals. Refer to the Parts List for
replacement decal information.
Severe burns and fire can result.
8. Never make adjustments or repairs
while engine is running.
15. Use only original-equipment replace-
ment parts. Parts manufactured by others
could present safety hazards and affect
performance even though they may fit on
this machine.
9. Components subject to wear, damage
and deterioration could expose moving
parts or allow objects to be thrown. Fre-
quently check components and replace
with factory recommended parts, when
necessary. Regularly inspect the trimmer
head and debris shield. Make sure they
are not bent, damaged or loose.
16. Remember—the end of the season is
a good time to inspect equipment prior to
storage.

STEP 2: INSTALL HANDLEBAR
ASSEMBLY STEPS
WARNING
1. Remove the plastic tie and tape that
secure the control bail (G, Figure 2-2) to
the handlebar (A).
To prevent personal injury or property
damage, do not start the engine until all
assembly steps are complete and you
have read and understand the safety and
operating instructions in this Manual.
STEP 1: UNPACKING UNIT
1. Remove any protective packaging (plas-
tic film and cardboard) from the handlebar
and the unit.
NOTE: Do not pinch or kink the cable that
is attached to the handlebar.
2. Carefully remove the handlebar (do not
pinch or kink the attached cable) before
removing the unit from the carton.
2. Carefully lift the handlebars (A, Figure
2-2) to the rear of the unit and align the
handlebar legs with the handlebar support
bracket (B).
INTRODUCTION
Carefully follow these assembly steps to
correctly prepare your machine for use. It
is recommended that you read this Sec-
tion in its entirety before beginning
assembly.
3. Check that you have received the fol-
lowing items:
3. Route the trimmer head control cable
(C, Figure 2-2) to the outside of the
handlebar.
• Trimmer/Mower Assembly (A, Figure

line.
• The following are packaged separately:
(3) Plastic Cable Tie
4. Select the low or high height setting
holes in the handlebar legs and attach the
legs to the support bracket (B) using two
5/16-18 x 1-1/2 hex hd. screws (D) and
5/16-18 locknuts (E).
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.
(1) Hex Hd. Screw, 1/4-20 x 2
(1) Hex Locknut, 1/4-20
(2) Hex Hd. Screw, 5/16-18 x 1-1/2
(2) Hex Locknut, 5/16-18
IMPORTANT: Adjust the handlebars as
close as possible to waist level so that
your arms are at a comfortable height.
This position will result in less pressure on
the mower wear cup (located at bottom of
trimmer head), making the unit easier to
roll and reducing wear to the wear cup.
INSPECTION AFTER DELIVERY
Inspect your machine immediately upon
delivery. Be sure that neither the carton
nor the contents have been damaged.
(2) Ignition Key*
If you find or suspect any damage, contact
the carrier (trucking company) right away.

Failure to follow gasoline safety rules
and instructions can result in serious
personal injury and property damage.
To adjust the cutting height:
INTRODUCTION
1. The cutting line height can be changed
when the wear cup is in contact with the
ground. If necessary, you may tip the unit
back slightly for a better view (do not tip
unit all the way back or motor oil may flow
to the exhaust area and the engine may
smoke for several seconds when started).
Read this Section thoroughly before start-
ing the engine. As with any piece of out-
door power equipment, getting the “feel”
for how the machine operates and know-
ing the best techniques for particular jobs
are important to overall good performance.
1. Lift and tilt plastic debris shield (E,
Figure 3-1) forward.
2. Clean fuel fill area and engine (see
“Cleaning Debris” in engine manual) each
time before fuel is added.
3. Fill the fuel tank with gasoline accord-
ing to the directions in the engine manual.
Follow all instructions and safety rules
carefully.
2. Use a 1/2" wrench to loosen the two
bolts (not the nuts) located on opposite
sides of the trimmer head (A, Figure 4-1).
NOTE: References to LEFT, RIGHT, FRONT
and REAR of the unit are determined by
standing in the operator’s position.
3. The cutting heights are marked on the
side of the spindle head (Figure 4-2).
Move the top of the trimmer head to the
desired setting.
4. Securely replace the fuel tank cap and
the fuel container cap. Promptly wipe up
any fuel spills.
PRE-START CHECKLIST
1. Review Section 1: “Safety” and Section
3: “Features and Controls”.
5. Lift and tilt the debris shield back, then
push it down to secure it.
4. Tighten both trimmer head bolts
securely (to 75 in/lbs.) and evenly.
2. Check for loose or missing hardware.
Tighten or replace as needed.
3. Check that the engine oil level is up to
the “FULL” mark on the dipstick. (See
engine manual for instructions.)
ADJUST HANDLEBAR HEIGHT
A
CAUTION
4. Check the fuel level. (See engine
manual and this page for instructions.)
Before adjusting handlebar height, stop
engine and wait for all moving parts to
stop, disconnect spark plug wire and
prevent it from touching spark plug.
NOTE: Clean debris from around fuel cap,
oil dipstick and engine (see “Cleaning
Debris” in engine manual) before checking
oil level or adding gasoline.
A
Failure to comply could result in
personal injury or property damage.
Figure 4-1
5. Check the Trimmer Head Control Bail
and the Engine Throttle Control Lever for
freedom of movement.
To adjust handlebar height, refer to “Install
Handlebars” in Section 2.
6. Select the cutting height (see “Adjust
Line Cutting Height” in this Section).
Height
Guide
ADJUST LINE CUTTING HEIGHT
7. Check handlebar height position.
The cutting height of the trimmer line can
be adjusted between 1-1/2" to 4-1/2". We
recommend that you start at a higher set-
ting and make adjustments as needed.
8. Carefully check the area to be trimmed
and remove any debris.
9. Install the correct diameter trimmer
line (see “Use the Correct Diameter Trim-
mer Line” in this Section).
In general, use higher settings to handle
taller material and to cope with tougher
cutting conditions. Use any trimming
height for less demanding conditions.

Section 4: Operation 11
TO START THE TRIMMER HEAD
USE THE CORRECT
DIAMETER TRIMMER LINE
1. Stand in the operator’s position
directly behind the handlebars.
Before starting a project, look at the grass
or material you will be cutting.
2. Slowly close the Trimmer Head Control
Bail (Figure 4-3) against the handlebars to
activate the trimmer head. Use the Engine
Throttle Control Lever to adjust the speed
of the trimmer head.
For tougher conditions, use two (or four)
sections of the thicker gauge, .155" diame-
ter extra-heavy duty line. For less
demanding conditions, use two sections
of the thinner gauge, .130" diameter
heavy-duty line. The thicker line has the
heft to chop through tougher materials,
while the thinner line provides a more pre-
cise cut. To change trimmer lines, refer to
“Changing Trimmer Lines” in Section 5.
A
3. Once the trimmer head is revolving,
push the unit along the path to be cut.
Figure 4-3: Control bail.
OPERATING THE MACHINE
Once you have read and understood the
sections in this Manual on “Safety,”
“Assembly,” “Features and Controls,” and
“Operation,” you are ready to operate
your machine.
TO STOP THE TRIMMER HEAD
Let go of the Trimmer Head Control Bail.
The bail will return to its open position and
the trimmer head will stop turning.
NOTE: The thinner line is also recom-
mended for use near trees or ornamentals
to help prevent girdling (cutting the bark).
TO STOP THE ENGINE
Put the Engine Throttle Control Lever in
the STOP position. (If time allows, first
move the throttle lever to the SLOW set-
ting before stopping the engine.)
CHECKLIST BEFORE STARTING
USING THE TRIMMER
HEAD CONTROL BAIL
Before starting the engine, know how to
use the Trimmer Head Control Bail.
1. Complete the “Pre-Start Checklist” in
this Section. You must wear safety
glasses or goggles.
2. Check the trimmer line cutting height
(see “Adjust Line Cutting Height” in this
Section.
1. The Trimmer Head Control Bail (A,
Figure 4-3) is used to start and stop trim-
mer head rotation.
NOTE: If the unit 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
the vegetation.
2. When starting the engine, always have
the control bail in the disengaged (released)
position to prevent the trimmer head from
turning when the engine starts.
STARTING THE ENGINE
1. Move the unit to the work area.
2. Connect spark plug wire to spark plug.
3. Put on safety-approved eye protection.
3. When the engine is running, pull the
control bail up against the handlebar to
start rotation of the trimmer head.
4. Release (disengage) the Trimmer Head
Control Bail (A, Figure 4-3).
WARNING
THROWN OBJECT HAZARD!
4. Let go of the control bail to stop the
trimmer head. The control bail should
spring forward to the disengaged position.
If it doesn’t, do not use the machine until
the control bail has been repaired.
5. Put Engine Throttle Control Lever in
FAST (rabbit symbol) position.
• 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.
6. Push in fuel primer button as instructed
in Engine Owner’s Manual. NOTE: Do not
use primer to restart a warm engine after a
short shutdown.
• Always wear safety-approved eye
protection and suitable clothing and
footwear.
WARNING
7. Recoil Starting:
If the trimmer head control bail is not
operating properly, shut off the
engine, disconnect the spark plug wire
and move the wire away from the plug.
Pull recoil start rope slowly until resis-
tance is felt. Then pull rope out rapidly
to start engine. Let rope back in
slowly. NOTE: If engine fails to start
after three pulls, repeat step 6
• Keep children, pets and bystanders
50 feet away from machine while
operating.
Adjust or repair the control bail
before using the trimmer/mower.
• Be alert to hidden obstacles.
Electric Starting:
Failure to comply could result in
injury or property damage.
Failure to follow this instruction could
result in personal injury or property
damage.

Section 4: Operation
OPERATING TIPS & TECHNIQUES
Tips for Precision Cutting
Use Extreme Caution on Slopes
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.
When operating on sloping ground, use extreme caution and
common sense to avoid possible injury or property damage.
Do not mow on excessively steep slopes! Avoid slopes if
greater than 150 or wherever footing is unsure. If a slope is
difficult to stand on, it is probably too steep to trim or mow.
In this case, it may be wiser to establish a permanent ground
cover on this area.
When mowing, let the cutting head rest lightly on the ground,
without lifting up or pushing down on the handlebars. This tech-
nique allows the cutting 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.
Grass and most other materials are most efficiently trimmed when dry. But the unit 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!
Trim When Wet or Dry
Clean the Unit On
a Regular Basis
Do Not Let the Trimmer Lines
Become Too Short
Keep the Mowed Side On the
Right While Moving Forward
The trimmer/mower discharges cut
materials to the right side.
Clean under the mower deck frequently
to remove any debris buildup. Also
clean around the muffler and on top of
engine.
When the trimmer lines wear to less
than 1/2 their original length, trimming
jobs will take far longer than necessary.
As a general guideline, install new lines
when they wear to 1/2 their original
length.
For best results, stay on the right side of
unmowed growth as you move along.
See the cleaning instructions in Section
5: “Maintenance.”
Vary the Throttle Setting
According to Conditions
Use the Correct
Walking Speed
The majority of trimming and mowing jobs will yield the best results if the
throttle control is set at the fastest speed.
Use a travel speed that is suitable for the condi-
tions at hand.
Less demanding jobs (and projects that require very precise cutting) will yield
better results if the engine speed is somewhat reduced. For example, damage
to trees and ornamentals can be avoided by reducing the engine speed, using
the lighter .130" diameter line, and by keeping a safe distance away.
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.
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.

BELT PERFORMANCE
TROUBLESHOOTING
CLEANING THE ENGINE
Spindle Mounting Plate
Front Pulley
Before each use of the machine and at
each refueling, clean grass, chaff or accu-
mulated debris from the finger guard area
(A, Figure 5-10) on top of the engine, and
from the linkage, springs and controls on
the engine. Keep the area around and
behind the muffler free of any combustible
debris. See “Cleaning Debris” in the
Engine Owner’s Manual for complete
cleaning instructions. Do not use water to
clean engine parts as water could contam-
inate the fuel system. Use a brush or dry
cloth. Be sure engine is cool before clean-
ing around muffler area.
Poor belt performance (noise, overheating,
cracking, etc.), can be caused by several
conditions. Follow the steps below to cor-
rect belt performance problems. Also use
these checks after installing a new belt.
After shutting the engine off and discon-
necting the spark plug wire, remove the
rear belt cover on the underside of the
machine (refer to previous page). Release
the Trimmer Head Control Bail to remove
all belt tension.

WARNING
the engine. Never operate the engine with-
out the air cleaner installed. Inspect and
service the air cleaner after every 25 oper-
ating hours, more often if operating in
very dusty or dirty conditions. Refer to
the Engine Owner’s Manual for cleaning or
replacement instructions.
• Never perform maintenance when
engine is running or spark plug wire is
connected, except when instructed to
do so.
Regular cleaning of debris from around the
engine and on the machine is required for
maximum engine efficiency and good over-
all performance. Inspect and clean the fol-
lowing areas regularly, making sure the
engine is stopped – and cool – before pro-
ceeding:
• Never store mower with fuel in fuel
tank inside a building where fumes can
reach an open flame or spark, or where
ignition sources are present such as
hot water and space heaters, furnaces,
clothes dryers, stoves, electric motors,
etc. Make sure engine is cool before
storing.
Spark Plug – 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 replace-
ment instructions.
• Brush and wipe off all engine surfaces,
especially before checking oil or adding
fuel. Do not let oil or grease accumu-
late. For access to the front of the
engine, the debris shield can be lifted up
and tilted forward.
Spark Arrester Screen – 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.
• Drain gasoline outdoors into an
approved container.Do not smoke and
keep fuel away from open flame.
• Wipe the deck clean, particularly near
the engine muffler.
Failure to follow these instructions will
result in serious personal injury or prop-
erty damage.
• Clean the underside of the deck.
Engine Cleaning – The engine must be
kept clean to assure smooth operation and
to prevent damage from overheating.
Refer to the Engine Owner’s Manual for
specific cleaning instructions.
• Keep safety and operating decals clean
and legible.
• Keep all control levers clean so they
work properly.
• Store machine on a level surface.
• Thoroughly inspect the machine for any
loose, broken or missing parts. Repair
or replace parts as necessary.
Carburetor/Governor Control
COMPACT STORAGE
Adjustments – The carburetor was
adjusted at the factory for best operating
speed. Refer to the Engine Owner’s Manual
for any adjustment information.
For compact storage, remove the two
screws and locknuts securing the handle-
bar 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.
• Protect the engine and perform the rec-
ommended engine maintenance by fol-
lowing the engine storage instructions
found in the Engine Owner’s Manual. Be
sure to protect the fuel lines, carburetor
and fuel tank from gum deposits by
removing fuel or by treating fuel with a
fuel stabilizer (follow the engine manu-
facturer’s recommendations).
The governor controls the maximum safe
operating speed and protects the engine
and other moving parts from damage
caused by overspeeding. Do not tamper
with the governor settings. Seek autho-
rized service if you think an adjustment is
required.
GENERAL ENGINE MAINTENANCE
Perform the following engine maintenance
for your engine according to the engine
maintenance schedule and instructions in
the separate Engine Owner’s Manual:
• Clean any dirt, grass or chaff from the air
cooling system intake area and other
parts of the engine.
Throttle Control Adjustment – If the
engine does not shut off when the throttle
lever is moved to the stop position, or if
the engine does not respond to various
throttle settings, refer to the Engine
Owner’s Manual for service information.
Engine Oil Service – Check the engine oil
level before starting the engine and after
each 5 hours of continuous operation.
Running the engine when it is low on oil
will quickly ruin the engine.
• For the electric start model, remove the
key from the keyswitch and store it in a
safe place. Charge the battery for 24
hours both before and after storage.
• Disconnect spark plug wire from spark
plug. Prevent wire from touching spark
plug by placing wire away from spark
plug.
Change the oil after every 25 hours of
operation and more often when operating
in extremely dirty or dusty conditions.
OFF-SEASON STORAGE
When storing the machine for extended
periods, follow these procedures to
ensure that the unit will be in good condi-
tion for future use.
Air Cleaner Service – The air cleaner fil-
ters dirt and dust out of the air before it
enters the carburetor. Operating the
engine with a dirty, clogged air filter can

CHANGING TRIMMER LINES
WARNING
each side of the line holder, creating an
overall 22" wide cutting swath. The two
lines can be offset to increase the cutting
swatch up to 25" wide. DO NOT offset the
lines 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 differ-
ent 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 pro-
pelled at high speeds.
Replace the trimmer lines when they
wear to the point that trimming and
mowing projects take too long and
requires too much maneuvering of the
machine. A good rule of thumb is to
change the lines when they reach half of
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.
5. Repeat steps 2 through 4 to replace
the second trimmer line.
Use the extra-heavy duty gauge (.155"
diameter) line when cutting thick, tough
growth. The thinner gauge (.130" diame-
ter) line is for use in less demanding con-
ditions, and is also recommended for use
near trees or ornamental plantings to
help prevent girdling (cutting of bark).
Figure 5-11: Use this
single line, easy-loop pat-
tern for all but the more
difficult cutting conditions.
To Change Trimmer Lines:
1. Stop engine, allow all moving parts to
stop and then disconnect the spark plug
wire and move it away from the spark
plug. 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 5-12: If lines tend to
loosen (especially in more
difficult cutting conditions),
add a single reverse loop
and then readjust line so
that ends are even. This
pattern results in a slightly
narrower cutting swath.
NOTE: The two line holders on the trim-
mer head are permanently secured by a
screw and nut. Do not attempt to remove
the line holders as it is not necessary to
remove them in order to change the trim-
mer 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 better view. How-
ever, 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 5-13: For more diffi-
cult cutting conditions, use
two of the thicker (.155"
diameter) lines in each line
holder. Follow the pattern
shown in Figure 5-11.
3. Three different line installation pat-
terns are available, as shown in Figures
5-11, 5-12 and 5-13.
4. Simply fee the line through the loops
of the line holder as shown. An equal
