FOREWORD
This Operator’s Manual contains safety precautions and operating procedures for the Cub Cadet
Commercial line of trimmers. You must read and understand this Operator’s Manual and especially the
Safety Precautions for proper and safe operation.
Cub Cadet Commercial's philosophy is to continually improve all of its products. As a result, engineering
changes and improvements are made from time to time. If the operating characteristics or the appearance
of your trimmer differ from those described in this Operator’s Manual, please contact your Cub Cadet
Commercial dealer for information and assistance. Contact your Cub Cadet Commercial dealer if you do
not understand any of the instructions in this manual.
Although hazard control and accident prevention are partially dependent upon the design and
configuration of the trimmers, these factors are also dependent upon the awareness, concern, prudence
and proper training of the personnel involved in the operation, transport, maintenance and storage of the
trimmers.

SAFETY PRECAUTIONS
GENERAL:
1. It is important that you read, fully understand and
observe the following safety precautions and
warnings. Read the Operator's Manual and the
safety instructions periodically.
2. Do not lend or rent out your trimmer without the
Operator’s Manual. Be sure that anyone using
your trimmer understands the information
contained in this Operator’s Manual.
3. Careless or improper use of this trimmer may
cause serious or even fatal injury.
4. The use of the trimmer can be hazardous. If the
rotating cutting line or a blade comes in contact
with your body, it will cut you. When it comes in
contact with solid foreign objects such as rocks
or bits of metal, it may fling them directly or by
ricochet in the direction of bystanders or the
operator.
5. Cub Cadet Commercial does not recommend the
use of rigid blades when cutting in stony areas.
Thrown objects or damaged blades may result in
serious or fatal injury to the operator or bystanders.
PHYSICAL CONDITION: You must be in good
physical condition and mental health and not under
the influence of any substance (drugs, alcohol, etc.)
which might impair vision, dexterity or judgment. Do
not operate the trimmer when you are fatigued.
1. Be alert - if you get tired while operating your
trimmer, take a break. Fatigue may result in loss
of control. Working with the trimmer can be
strenuous. If you have any condition that might
be aggravated by strenuous work, check with
your doctor before operating the trimmer.
2. Prolonged use of the trimmer (or other machines) exposing the operator to vibrations may
produce whitefinger disease (Raynaud's
phenomenon) or carpal tunnel syndrome. These
conditions reduce the hand's ability to feel and
regulate temperature, produce numbness and
burning sensations and may cause nerve and
circulation damage and tissue necrosis.
Antivibration systems do not guarantee that you
will not sustain whitefinger disease or carpal
tunnel syndrome. Therefore, continual and
regular users should monitor closely the
condition of their hands and fingers. If any of the
above symptoms appear, seek medical advice
immediately.
PROTECTIVE CLOTHING: Trimmer operation can
cause serious injury to eyes, ears and body. The
deflector provided with your trimmer may not
protect the operator from all foreign objects (gravel,
glass, wire, etc.) thrown by the rotating cutting line
or blade. Thrown objects may also ricochet and
strike the operator.
1. Clothing must be sturdy and snug-fitting, but
allow complete freedom of movement. Avoid
loose-fitting jackets, scarfs, neckties, jewelry,
flared or cuffed pants, unconfined long hair or
anything that could become caught on branches,
brush or moving parts of the unit. Wear long
pants made of heavy material to protect your
legs. DO NOT WEAR SHORTS.
2. To reduce the risk of injury to your eyes, never
operate the trimmer unless wearing goggles or
properly fitted safety glasses with adequate top
and side protection complying with ANSI Z 87.1.
3. To reduce the risk of injury to your face Cub
Cadet Commercial recommends that you also
wear a face shield or face screen over your
goggles or safety glasses.
4. Trimmer noise may damage your hearing. Wear
sound barriers (ear plugs or ear mufflers) protect
your hearing. Continual and regular user should
have their hearing checked regularly.
5. Protect your hands with gloves when handling
the trimmer. Heavy-duty, nonslip gloves improve
your grip and protect your hands.
6. Good footing is most important in trimmer work.
Wear sturdy boots with nonslip soles. Steel-toed
safety boots are recommended.
7. Wear an approved safety hard hat to reduce the
risk of injury to your head.
PROTECTING OTHERS:
1. Minors should never be allowed to use the
trimmer.
2
2. Spectators, children, fellow workers and animals
must be warned to stay back 50 feet (15m) while
the trimmer is in use. Stop the engine and cutting
head immediately if you are approached.
SAFETY PRECAUTIONS
fuel.
3. Fuel your trimmer outdoors or in a well-ventilated
area.
3. People working in the area near you should wear
the same protective equipment as the operator.
PREPARATION FOR THE USE OF THE
TRIMMER:
1. Never modify the trimmer in any way. Only
attachments supplied by Cub Cadet Commercial
or expressly approved by Cub Cadet Commercial for use with the specific Cub Cadet Commercial trimmer models are authorized. Although
certain unauthorized attachments are usable
with the Cub Cadet Commercial trimmer, their
use may, in fact, be extremely dangerous.
2. When transporting your trimmer in a vehicle,
properly secure it to prevent turnover, fuel
spillage and damage to the trimmer.
3. Always use the shoulder harness when using
rigid blades.
4. Adjust the shoulder harness and hand grips to
suit your size before starting work.
5. Always check your trimmer for proper condition
and operation before starting, particularly the
throttle trigger, throttle trigger interlock, stop
switch, cutting head or blade, deflector and
harness.
6. The throttle trigger must move freely and always
spring back to the idle position. The cutting head
must be properly tightened and in safe operating
condition. Inspect for loose parts (nuts, screws,
etc.).
HANDLING FUEL: The Cub Cadet Commercial
trimmer uses an oil-gasoline
mixture for fuel.
4. Select bare ground for fueling and move at least
10 feet (3 m) from the fueling spot before starting
the engine.
5. Gasoline vapor pressure may build up inside the
gas tank of a two cycle engine depending on the
fuel used, the weather conditions, and the
venting system of the tank. In order to reduce the
risk of personal injury from escaping gas vapor
and fumes, remove the fuel filler cap on your
trimmer carefully so as to allow any pressure
buildup in the tank to release slowly.
6. Never remove the fuel filler cap while the engine
is running.
7. Unit vibrations can cause an improperly
tightened fuel cap to loosen or come off
permitting fuel to spill. In order to reduce the risk
of fuel spillage and fire, tighten the fuel cap by
hand with as much force as possible.
8. Wipe off any spilled fuel before starting your
trimmer.
9. Check for fuel leakage while refueling and during
operation. If fuel or oil leakage is found, do not
start or run the engine until the leak is fixed and
spilled fuel has been wiped away.
10. If fuel spills on your clothing, change your
clothing immediately.
CARBON MONOXIDE HAZARDS:
1. If you operate the trimmer in an area that is
confined, or even partially enclosed, the air you
breathe could contain a dangerous amount of
exhaust gas. To keep exhaust gas from building
up, provide adequate ventilation.
1. Gasoline is an extremely flammable fuel. If
spilled and ignited by a spark or other ignition
source, it can cause fire, serious burn injury and
property damage. Use extreme caution when
handling gasoline or an oil-gasoline fuel mixture.
2. Do not smoke or bring any fire or flame near the
2. The exhaust gas contains carbon monoxide, a
poisonous, colorless and odorless gas. Breathing the exhaust gas can cause loss of consciousness and may lead to death.
3
SAFETY PRECAUTIONS
STARTING: Your trimmer is a one-person machine.
1. Start and operate your trimmer without assistance. When starting, place the trimmer on firm
ground or a solid surface in an open area.
Maintain good balance and secure footing.
2. To reduce the risk of injury from loss of control,
be absolutely sure that the cutting head or blade
is clear of you and all other obstructions and
objects, including the ground when starting,
because when the engine starts, the engine
speed will be fast enough for the clutch to
engage and turn the cutting head or blade.
3. When you pull the starter grip, do not wrap the
starter rope around your hand. Do not allow the
grip to snap back, but guide the starter rope to
rewind properly. Failure to follow this procedure
may result in injury to your hand or fingers and
may damage the starter mechanism.
OPERATION:
1. Work carefully.
2. To reduce the risk of injury from thrown objects
or blade contact, never operate the trimmer
without a properly mounted deflector.
3. Operate the trimmer under good visibility and
daylight conditions only.
4. Always hold the trimmer firmly with both hands.
Wrap your fingers tightly around the handles,
keeping the handles cradled between your
thumb and forefinger. Keep your hands in this
position, to have your trimmer under control at all
times.
5. Make sure your trimmer handles and grips are in
good condition and free of moisture, pitch, oil or
grease.
6. Never attempt to operate the trimmer with one
hand. You might lose control of the trimmer
resulting in serious or fatal injury.
7. To reduce the risk of bodily injury resulting from
loss of control and contact with the cutting head,
always attach and wear the shoulder harness on
those trimmers equipped with a straight shaft
and loop handle.
8. Before trimming, inspect the area for stones,
glass, pieces of metal, trash or other solid
objects. The cutting line could throw objects of
this kind.
9. This trimmer is to be used normally at ground
level with the cutting head or blade parallel to the
ground. Using the trimmer above ground level or
with the cutting head or blade perpendicular to
the ground may increase the risk of injury, since
the cutting line or blade is more fully exposed
and the trimmer may be more difficult to control.
Never use your trimmer as a hedge trimmer.
10. When using rigid blades, avoid cutting close to
fences, sides of buildings, tree trunks, stones or
other such objects that could cause the trimmer
to kick out or could cause damage to the blade.
Cub Cadet Commercial recommends use of the
nylon line heads or Polycut head for such jobs.
In addition, be alert to an increased possibility
of ricochets in such situations.
11. Do not use the starting throttle lock when you
are trimming as you do not have control of the
engine speed. For the proper use of the throttle
lock, see “Starting” in the Operation Section.
12. If the cutting tool or deflector becomes clogged
or stuck, always turn off the engine and make
sure the cutting tool has stopped, before
cleaning. Grass,weeds, etc. should be cleaned
off the cutting tool at regular intervals.
13. During cutting, check the tightness and the
condition of the cutting tool at regular intervals.
If the behavior of the tool changes, stop the
engine immediately, and check the bolt
securing the tool for tightness and the cutting
tool for cracks and damage.
14. Replace cracked, bent, warped, damaged or
dull cutting blades immediately. Such tools may
shatter at high speed and cause serious or fatal
injury.
15. A loose blade may cause the blade to crack,
vibrate, break or come off the trimmer, which
may result in serious or fatal injury. Make sure
that the blade is properly tightened. Use the
wrench supplied or one of sufficient length to
obtain the proper torque. If the blade loosens
after being properly tightened, stop work
4
immediately. The retaining bolt may be worn or
damaged and should be replaced. Never use
unauthorized parts to secure the blade. If the
blade continues to loosen, see your Cub Cadet
Commercial dealer. Never use a trimmer with a
loose blade.
16. To reduce the risk of personal injury from loss of
control, do not use an incorrect idle adjustment.
At correct idle speed, the head and line or
blade should not move. For instructions on
adjusting the idle speed, see “Carburetor
Adjustment” in the Maintenance Section.
17. Never touch a rotating cutting tool with your
hand or any part of your body. It continues to
rotate for a short period after the throttle trigger
is released.
18. Always turn off the engine and make sure the
cutting line has stopped before putting the
trimmer down.

WARNING
Reread the Safety Precautions relating
to “Handling Fuel” on Page 3.
The Cub Cadet Commercial trimmer uses an oilgasoline mixture as fuel. The engine is certified to
operate on unleaded gasoline.
Use regular name-brand unleaded gasoline with a
minimum octane number of 89. If the octane
number of the regular grade gasoline in your area
is lower use premium unleaded fuel. Fuel with a
lower octane number may result in preignition
(causing “pinging”) which is accompanied by an
increase in engine temperature. This, in turn,
increases the risk of piston seizure and damage to
the engine.
The chemical composition of the fuel is also
important. Some fuel additives not only
detrimentally affect elastomers (carburetor
diaphragms, oil seals, fuel lines etc.), but
magnesium castings as well. This could cause
running problems or even damage the engine. For
this reason it is essential that you use only namebrand fuels!
IMPORTANT:
Do not use any gasoline containing alcohol.
Serious engine or fuel system damage will occur.
Use only quality two-stroke, air-cooled engine oil
with the classification TC. The mix ratio is 25-30:1.
We recommend Cub Cadet Commercial brand 2Stroke Engine Oil since it is specially tested for use
in all Cub Cadet Commercial two-stroke engines.
The mix ratio is 50:1
IMPORTANT:
Do not use BIA or TCW (two-stroke water cooled)
mix oils!
Directions for Mixing: (See Chart for Amounts)
1. Put one-half of the gasoline in a safety approved
container.
2. Add the proper amount of two-stroke oil and mix
thoroughly.
3. Add the remainder of the gasoline and mix
thoroughly.
Take care when handling gasoline. Avoid direct
contact with the skin and avoid inhaling fuel vapor.
The gasoline container should be kept tightly
closed in order to prevent any moisture getting into
the mixture.
Only mix sufficient fuel for a few days work, not to
exceed 30 days of storage. Store in a safety
approved fuel container only.

Dispose of empty two-stroke oil containers at
authorized disposal locations only.
CAUTION
The engine used on this trimmer is of a 2-cycle
design. The internal moving parts of the engine,
f.e., crankshaft bearings, piston pin bearings and
piston to cylinder wall contact surfaces, require
oil mixed with the gasoline for lubrication. Failure
to add oil to the gasoline or failure to mix oil with
the gasoline at the appropriate ratio will cause
major engine damage which will void your
warranty. For your fuel premix, only use Cub
Cadet Commercial brand 50:1 2-cycle oil or a
quality oil designed for 2-cycle air cooled
engines.
12
FUELING INSTRUCTIONS
FUEL MIXTURE :
When using Cub Cadet Commercial 50:1 2-cycle
brand oil, or a quality oil designed for 2-cycle aircooled engines, oil ratio is 50 parts gasoline to 1
part oil or 50:1.
CAUTION
Never use a mixing ratio greater than 50:1
regardless of the oil package mixing instructions.
Ratios greater than 50:1,(for example, 60:1,
80:1, 100:1), reduce the amount of lubrication to
the internal moving parts of the engine and can
cause damage.
MIXING INSTRUCTIONS :
Always mix fuel and oil in a clean container
approved for gasoline. Mark the container to
identify it as fuel mix for the trimmer. Use regular
unleaded gasoline and fill the container with half
therequired amount of gasoline. Pour the correct
amount of oil into the container then add the
remaining amount of gasoline. Close the container
lightly and shake it momentarily to evenly mix the
oil and the gasoline before filling the fuel tank on
the trimmer.
When refilling the trimmer fuel tank, clean around
the fuel tank cap to prevent dirt and debris for
entering the tank during cap removal. Always shake
the premix fuel container momentarily before filling
the fuel tank.
Always use a spoul or funnel when fueling to
reduce fuel spillage. Only fill the tank to within 1/41/2 inch from the top of the tank. Avoid filling to the
top of the tank filler neck.
NOTE:
1. Never mix gasoline and oil directly in the
trimmer fuel tank.
2. Check for fuel leakage around the tank cap
and the fuel tank before the operation.
CAUTION
1. Do not use National Marine Manufacturer’s
Association (NMMA) or BIA certified oils. This
type of 2-cycle engine oil does not have the
proper additives for air-cooled, 2-cycle
engines and can cause engine damage.
2. Do not use automotive motor oil. This type of
oil does not have the proper additives for aircooled, 2-cycle engines and can cause
engine damage.

A. CARBURETOR ADJUSTMENT.
The carburetor is preset at the factory. This is the
optimum setting under the barometric pressure and
climatic conditions at the factory and is suitable for
most operating sites.
It ensures that your machine will run smoothly, be
fuel efficient, operate reliably and produce low
emissions.
If the engine runs unsatisfactorily at high altitudes
or at sea level, slight readjustment of the carburetor
may be necessary:
NOTE
Every unit is run at the factory and the carburetor is
set in compliance with EPA. In addition, the
carburetor is equipped with H and L needle
adjustment limiters that prevent settings outside
acceptable limits.
1. Check the air filter and clean it if necessary.
2. Check the spark arresting screen (if fitted) and
clean it if necessary.
H
I
3. Mount the cutting tool.
a. Nylon line trimmer head:
Trim lines to the correct length. (The lines must
extend as far as the line limiting blade on the
deflector.
4. Start the engine and adjust the idling speed
correctly with the idle speed adjusting screw
(Ref. I). The cutting tool must not rotate.
5. Warm up the engine.
18
L
6. Adjusting the idle speed:
It is usually necessary to change the setting of
the idle speed adjusting screw (Ref. I) after every
correction to the low speed adjusting screw (Ref.
L).
7. Proper idling speed:
ST23,26............. 2,800-3,000 rpm
ST35.................. 2,500-2,700 rpm
8. The engine stops while idling:
Turn the idle speed adjusting screw (Ref. I)
clockwise until the engine runs smoothly, but the
cutting tool must not rotate.
9. The cutting tool rotates when the engine is
idling:
Turn the idle speed adjusting screw (Ref. I)
counterclockwise until the cutting tool stops
rotating then return the screw about another half
turn from that position.
10. Erratic idling behavior, poor acceleration:
The idle setting is too lean. Turn the low speed
adjusting screw (Ref. L) counterclockwise until
the engine runs and accelerates smoothly.
11. Adjusting high speed:
Adjust the low adjustment screw (Ref. L) for the
smooth engine idling. Then increase the engine
speed and adjust the high speed adjustment
screw (Ref. H) for stable engine rotation. The
engine acceleration should be smooth with
proper adjustment.
(High Engine Speed..........10,000-11,000 rpm)

B. THE THROTTLE WIRE ADJUSTMENT
C. CHECKING THE SPARK PLUG.
0.5mm-0.6mm
A
0.020”-0.024”
The wrong fuel mix (too much engine oil in the
gasoline), a dirty air filter or unfavorable running
conditions (mostly at low throttle) affect the
condition of the spark plug. These factors cause
deposits to form on the insulator nose which may
result in faulty operation.
1
2
1. Maintain a wire end-play of about 1/16 inch (12mm) with the adjuster and fix it with the
tightening bolt (Ref.2).
WARNING
To reduce the risk of injury from loss of control,
maintain the wire end-play at about 1/16 inch
(1-2mm). If the wire end-play is not maintained,
engine speed may be enough for the clutch to
engage and turn the cutting tool.
1. If the engine doesn't seem to have any power, is
difficult to start or runs poorly at idling speed, first
check the spark plug.
2. Remove the spark plug and see "3. If the Engine
Doesn't Start" on page 14.
3. Clean the dirty spark plug.
4. Check the electrode gap.
It should be 0.20in.(0.5mm) - 0.024in.(0.6mm)
Re-gap if necessary.
5. Use only a suppressed spark plug of the
approved type:
NGK BPMR7A
Correct the problems which caused the fouling of
the spark plug:
Incorrect carburetor setting, too much oil in the
fuel mix, dirty air filter, unfavorable running
conditions, e.g. operating at partial load.
20
MAINTENANCE
D. CLEANING THE AIR FILTER.
Dirty air filters reduce engine power, increase fuel consumption and make starting more difficult.
If there is a noticeable loss of engine power:
ST23, 26

1. Turn the choke lever (Ref. 1) to “CLOSE”.
Loosen the screw (Ref. 2) and remove the air
filter cover (Ref. 3).
2. Remove the foam element (Ref 4) and felt
element (Ref.5).
3. Wash the air filter in warm, soapy water and dry.
4. Always replace a damaged foam element.
5. Fit the foam element in the filter housing.

IMPORTANT
To maintain proper engine operating
temperatures, cooling air must pass freely
through the cylinder fin area. This flow of air
carries combustion heat away from the engine.
Air out flow
3
Air out flow
6. Fit the filter cover and engage it in position.
7. Tighten the screw firmly.
E. COOLING SYSTEM MAlNTENANCE.
The cooling system relies on cooling air entering
the engine through the bottom engine grille located
between the fuel tank and starter. The
cooling fan pushes this air through the cylinder fin
area and out the rear grille openings in the engine
cover.
Air intake
Overheating and engine seizure can occur when:
1. Air intakes are blocked, preventing cooling air
from reaching the cylinder.
21
MAINTENANCE
2. Dust and grass build up on the outside of the
cylinder. This buildup insulates the engine and
prevents the heat from leaving.
2. Place the piston at top dead center. Clean any
deposits from the muffler and the cylinder
exhaust port with a nonmetallic scraper.
Removal of cooling passage blockages or cleaning
of cylinder fins is considered “Normal
Maintenance”. Any resultant failure attributed to
lack of maintenance is not warranted.
F. CLEANING THE CYLINDER FINS.
(Check Periodically)
1. Remove any dust and dirt from between the fins.
2. If greater access is needed to thoroughly clean
the fins, remove the engine cover as illustrated.
Cylinder fins
G. CLEANING THE EXHAUST PORT.
This procedure requires specialized engine service
techniques and the proper tools. Contact the
authorized Cub Cadet Commercial dealer where
you bought your trimmer or your nearest Cub Cadet
Commercial Service Center.
IMPORTANT
Do not use a metal tool to scrape carbon from
the exhaust port. Be careful not to scratch the
cylinder or piston when cleaning the cylinder
exhaust port.
3. Inspect the gasket, and replace it if necessary.
4. Install the muffler.
5. Fit the gasket and cover.
H. CLEANING THE CLUTCH AND
CLUTCH DRUM.

DO NOT overfill the housing.
3. Tighten the filler plug firmly.
K. LUBRICATING THE DRIVE SHAFT.
Shaft
2. Before storing your machine for a long period,
drain and clean the fuel tank and run the engine
until the carburetor is dry.
3. The fuel tank and the container in which the fuel
mix is stored should be cleaned from time to
time.
J. LUBRICATING THE GEAR HEAD.

U. S. EPA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The U.S. Environmental Protection Agency (EPA), Cub Cadet Corporation and the engine manufacturer for this
equipment, Ishikawajima Shibaura Machinery Co., Ltd. (ISM), are pleased to explain the federal emission control
systems warranty on your engine.
In the U. S. (exclude the state of California), new 1997 and later model year engines must be designed, built, and
equipped, at the time of sale, to meet the EPA regulations for small nonroad engines. The engine must be free from
defects in materials and workmanship during the period of warranty coverage (see PERIOD OF WARRANTY
COVERAGE below). ISM must warrant the emission control system on your engine for that period provided there has
been no abuse, neglect or improper maintenance of your engine.
Your emission control system may include parts such as the carburetor and the ignition system (see EMISSION
CONTROL WARRANTY PARTS LIST below).
Where a warrantable condition exists, Cub Cadet Corporation will repair your engine at no cost to you, including
diagnosis, parts, and labor, on behalf of ISM. While ISM is ultimately responsible for this warranty, Cub Cadet
Corporation has agreed to carry out ISM’s warranty repair responsibilities, and Cub Cadet Corporation should be your
primary contact for emission-related warranty service.
PERIOD OF WARRANTY COVERAGE
1997 and later utility and small nonroad engines are warranted for two years. If any emission-related part on your
engine is defective, the part will be repaired or replaced by Cub Cadet Commercial on behalf of ISM.
OWNER’S RESPONSIBILITIES
(a) As the engine owner, you are responsible for the performance of the required maintenance listed in your Operator’s
Manual. Cub Cadet Commercial and ISM recommend that you retain the original purchase documentation and all
receipts covering maintenance on your engine, but Cub Cadet Commercial and ISM cannot deny warranty solely
for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
(b) As the engine owner, you should be aware, however, that Cub Cadet Commercial and ISM may deny you warranty
coverage if your engine or a part has failed due to abuse, neglect, improper maintenance or unapproved
modifications.
(c) You are responsible for presenting your engine to an authorized Cub Cadet Corporation servicing facility as soon
as a problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30
days.
If you have any questions regarding your warranty rights and responsibilities, call Cub Cadet Corporation at 330-273-
