General Safety Rules
SAVE THESE INSTRUCTIONS
WARNING! Read all instructions Failure to follow all instructions
listed below may result in electric shock, fire and/or serious injury.
The term “power tool” in all of the warnings listed below refers
to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1) Work area
a) Keep work area clean and well lit. Cluttered and dark areas
invite accidents.
b) Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust or
fumes.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock
b) Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
d) Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a power
tool while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while
operating power tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety
equipment such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate conditions will
reduce personal injuries.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool
for your application. The correct power tool will do the job
better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on
and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power source before making
any adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do
not allow persons unfamiliar with the power tool or these
instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other condition
that may affect the power tools operation. If damaged, have
the power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind and
are easier to control.
g) Use the power tool, accessories and tool bits etc., in
accordance with these instructions and in the manner
intended for the particular type of power tool, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations different from
intended could result in a hazardous situation.
5) Battery tool use and care
a) Ensure the switch is in the off position before inserting
battery pack. Inserting the battery pack into power tools that
have the switch on invites accidents.
b) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with another
battery pack.
c) Use power tools only with specifically designated battery
packs. Use of any other battery packs may create a risk of
injury and fire.
d) When battery pack is not in use, keep it away from other
metal objects like paper clips, keys, nails, screws, or
other metal objects that can make a connection from one
terminal to another. Shorting the battery terminals together
may cause burns or a fire.
e) Under abusive conditions, liquid may be ejected from the
battery; avoid contact. If contact accidentally occurs, flush
with water. If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may cause
irritation or burns.
5) Service
a) Have your power tool serviced by a qualified repair person
using only identical replacement parts. This will ensure that
the safety of the power tool is maintained.
c) Avoid accidental starting. Ensure the switch is in the
off-position before plugging in. Carrying power tools with
your finger on the switch or plugging in power tools that have
the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all
times. This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewellery or long hair can be caught in
moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of these devices can
reduce dust-related hazards.

Control Identification and Use

WARNING!
Do not smoke or allow smoking near fuel or the Trimmer.
Mix and pour fuel outdoors WHERE THERE ARE NO
SPARKS OR FLAMES.
The 2-cycle engine on your Trimmer requires that fuel and
2-cycle engine oil be pre-mixed before adding to the
trimmer’s fuel tank. To mix the fuel/ 2-cycle oil:
1. Throttle (Fig. 15)
The throttle lever (12) is located on the top crossbar on
the upper handle. Depressing the throttle lever will
increase the engine speed. At idle speed the clutch is
disengaged and the trimmer head will not turn. As engine
speed is increased, the automatic clutch will engage and
rotate the trimmer head. Upon release, the throttle lever
is spring loaded to return to idle speed.
2. Swivel to offset trimmer head (Fig. 16)
Your wheeled string trimmer mower is designed with the
ability to offset the trimming head from a centered
position to a right side position. This is accomplished by
depressing the swivel control lever (13) on the right
upper handle. By depressing the swivel control lever, the
head becomes unlocked and can be swiveled to two
positions to the right. Upon release of the swivel control
lever, a pin will lock the trimmer head into the desired
position. Swiveling the trimmer head allows for easy
mowing / trimming around obstacles such as posts or trees
and under fences.
3. Bevel trimming adjustment (Fig. 17)
The line will normally cut approximate 50mm high. When
it is desired that the line cut closer to the ground, a bevel
adjustment is available. Bevel handle (4) is located just in
front of the left wheel. This handle can be deflected
outward and rotated to two different positions. This will
position the trimmer head at an angle and allow the line
to cut closer to the ground. This is especially useful when
trimming next to raised sidewalks or building foundations.
4. Start / Stop switch (Fig. 18)
On/Off ignition switch (17) is located on the engine air
filter housing. The switch must be in the “On” position for
the engine to run. Moving the switch to the “Off” position
will stop the engine.
1. Your Trimmer performs best when the engine operates at
high speed and the tips of the line cut the vegetation. Do
not force the trimmer line into grass faster than the
Trimmer’s cutting speed permits.
2. The tips of the line can cause damage to trees, shrubs
and fences. To avoid damage in these conditions, you
may choose to run the engine at lower speeds and
should carefully monitor the location of the cutting line.
3. Because the cutting head can be pivoted to the right side,
plan to trim objects (fences, buildings, etc.) in a clockwise
manner.
4. When trimming next to wire type fencing, avoid
cutting-line contact with the fence. Contact will result in
rapid line wear. Likewise, contact with concrete and brick
surfaces will result in rapid line wear.
5. Do not allow the trimmer head metal bowl to ride on top
of concrete or asphalt surfaces. This will cause wear to
the metal bowl. The bowl was designed to ride on grass
surfaces.
6. It is recommended that the line be replaced when it is
worn to approximately ½ the original length. This will help
maintain a high tip speed and result in a clean cut. It is
strongly recommended that the engine cooling air screen
be wiped clean at every string change. This will prevent
engine overheating.
7. Choose your line diameter according to the following
criteria:
a. 2.4 / 2.7 mm diameter: Best overall choice for yard
use. This diameter results in a good quality of cut and
moderate wear rate.
b. 4.0 mm diameter: Ability to cut larger diameter stalks
and has the best wear rate.

Recommendations
1. Use fresh unleaded gasoline with an octane rating of 87
or higher. Do not use gasoline containing more than 10%
ethanol.
NOTICE:Use of gasoline containing more than 10%
ethanol can damage Trimmer. Use of non-ethanol
gasoline is best.
2. Always use 2-cycle oil that meets or exceeds JASO – FC
specifications and is intended for mixing at a fuel/oil ratio
of 50:1
3. Do not use automotive or 2-cycle marine outboard oil.
These will damage your Trimmer’s engine and void the
warranty.
4. Always mix the gasoline and 2-cycle oil in a container
approved for gasoline. Never mix fuel directly in the
trimmer’s fuel tank.
Before Starting Engine
Mixing Fuel / 2-Cycle Oil

WARNING!
Keep all parts of your body away from cutting area, the
rotating trimmer lines and hot surfaces.
NOTE: DO NOT depress the throttle lever until engine
starts and runs.
NOTE: When the weather gets cold, please allow the
ngine to warm up at idle for longer period of time, before
engaging to RUN/WARM START position.
10
For 4.0 mm Diameter Line: (Fig. 27-28)
1. Stop the engine and remove spark plug lead.
2. Cut two lengths of trimmer line to 420 mm.

Techniques / Applications:
Trimming Tip
To extend the life of the trimmer line, keep the trimmer line
moist. If not kept moist, the nylon line will become dry and
brittle. Keep extra trimmer line in a container of water. The
line will stay flexible and easy to change. A flexible line will
also last longer.
NOTICE
It is recommended that the engine air intake screen be
cleaned every time the trimmer line is replaced. Failure to
keep the air intake screen clean may result in overheating
and damage to engine.
WARNING!
Thoroughly inspect the area where the Trimmer is to be
used and remove all foreign objects. Your equipment can
throw small objects at high speed causing personal injury or
property damage.
Your Trimmer is most effective when using the tips of the
trimmer line for trimming grass and other vegetation. Do not
force the trimmer line into grass or vegetation faster than
Trimmer’s cutting speed permits. Forcing the Trimmer will
cause your Trimmer to be less effective, and may cause the
engine to overheat.
Air Filter:
Your Trimmer has been equipped with two air filters inside
the housing. Accumulated debris and dust in the air filter
will reduce engine performance, increase fuel consumption
and increases the risk of engine damage. Clean the air
filters every 5 hours of operation. It may be necessary to
clean the air filter more often in dry conditions due to a
large amount of airborn debris.
ROUTINE MAINTENANCE
WARNING!
Disconnect the spark plug before performing maintenance.
1. Allow engine to cool and empty the fuel tank before
storing or transporting in vehicle. Use up remaining fuel
in the carburetor by starting the engine and letting it run
until it stops.
2. When not in use, store Trimmer indoors in a dry location.
Store Trimmer in a locked area out of the reach of
children.
3. Store unit and fuel in area where fuel vapors cannot
reach sparks or open flames from water heaters, electric
motors or switches, furnaces, etc.
STORAGE
1. Stop the engine and disconnect the spark plug wire.
2. Allow the unit to cool.
3. Using a dry cloth or brush, remove debris from the
screen. The screen is located between the engine and
the fuel tank and is accessible on all sides.
4. The front flexible shield can be deflected for access to
the front screen.
WARNING!
The engine and exhaust system may be hot and can cause
skin burns. Allow engine to cool and use caution around hot
surfaces.
Spark Plug:
Inspect the spark plug after every 10-15 hours of use; adjust
spark plug gap and replace spark plug as necessary.
Replace spark plug every year to maintain engine
performance and easy starting.
To inspect or replace the spark plug:
1. Remove the insulated spark plug boot.
2. Use the spark plug wrench to remove the spark plug, by
turning counter-clockwise.
3. Clean and adjust the spark plug gap to 0.6 - 0.7 mm.
4. Replace any worn plug with a recommended replace-
ment (see PRODUCT SPECIFICATIONS) Clean and
adjust the spark plug gap to 0.6 - 0.7 mm.
Trimmer Head:
1. If the string retention parts become filled with debris, they
can be removed using a 5 mm hex wrench. When
reinstalling, only tighten to 5 N.m and assure the inner
part is free to move.
2. If it is necessary to remove the trimmer bowl and head
note that the large retaining nut has a left hand thread
(i.e. to remove the nut turn clockwise).
Engine Air Intake Screen:
NOTICE
It is critical that the engine air intake screen be cleaned of
debris to maintain acceptable engine temperatures. It is
recommended that the screen be cleaned every time the
trimmer string is replaced.

12
NOTICE
To prevent fuel gum deposits and corrosion in the
Trimmer’s carburetor and fuel system, it is highly
recommended to use a fuel additive / stabilizer formulated
for ethanol fuels. Follow the stabilizer manufacturer’s
instructions. Run the engine at least 5 minutes after adding
stabilizer.
4. When preparing the Trimmer for storage or when
Trimmer will not be used for 30 days or more:
a. Inspect and clean the Trimmer thoroughly.
b. Lightly oil all external metal surfaces.
c. Remove the spark plug, place a few drops of 2-cycle
engine oil into the cylinder. Pull the recoil starter
several times to distribute the oil. Replace the spark
plug.
