GENERAL MACHINE SAFETY
WARNINGS
WARNING:
Read all safety
warnings, instructions, illustrations and
specifications provided with this machine.
Failure to follow all instructions listed below
may result in electric shock, re and/or
serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE.
The term “machine” in the warnings refers
to your mains-operated (corded) machine
or battery-operated (cordless) machine.
WORK AREA SAFETY
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. Do not operate machines in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Machines
create sparks which may ignite the dust or
fumes.
3. Keep children and bystanders away
while operating a machine. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
1. Machine plugs must match the outlet.
Never modify the plug in any way. Do
not use any adapter plugs with earthed
(grounded) machines. Unmodied plugs
and matching outlets will reduce risk of
electric shock.
2. 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.
3. Do not expose machines to rain or wet
conditions. Water entering a machine will
increase the risk of electric shock.
4. Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging the
machine. Keep cord away from heat, oil,
sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric
shock.
5. When operating a machine outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
6. If operating a machine in a damp
location is unavoidable, use a ground fault
circuit interrupter (GFCI) protected supply.
Use of an GFCI reduces the risk of electric
shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing
and use common sense when operating
a machine. Do not use a machine while
you are tired or under the influence of
drugs, alcohol or medication. A moment of
inattention while operating machines may
result in serious personal injury.
2. Use personal protective equipment.
Always wear eye protection. Protective
equipment such as a dust mask, non-skid
safety shoes, hard hat or hearing protection
used for appropriate conditions will reduce
personal injuries.
3. Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and/or battery
pack, picking up or carrying the machine.
Carrying machines with your nger on the
switch or energizing machines that have the
switch on invites accidents.
4. Remove any adjusting key or wrench
before turning the machine on. A wrench or
a key left attached to a rotating part of the
machine may result in personal injury.
5. Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the machine in unexpected
situations.
Page 5
SAFETY INSTRUCTIONS
6. Dress properly. Do not wear loose
clothing or jewelry. Keep your hair and
clothing away from moving parts. Loose
clothes, jewelry or long hair can be caught
in moving parts.
7. If devices are provided for the
connection of dust extraction and
collection facilities, ensure these are
connected and properly used. Use of dust
collection can reduce dust-related hazards.
8. Do not let familiarity gained from
frequent use of machines allow you to
become complacent and ignore machine
safety principles. A careless action can
cause severe injury within a fraction of a
second.
MACHINE USE AND CARE
1. Do not force the machine. Use the
correct machine for your application. The
correct machine will do the job better and
safer at the rate for which it was designed.
2. Do not use the machine if the switch
does not turn it on and off. Any machine
that cannot be controlled with the switch is
dangerous and must be repaired.
3. Disconnect the plug from the power
source and/or remove the battery pack,
if detachable, from the machine before
making any adjustments, changing
accessories, or storing machines. Such
preventive safety measures reduce the risk
of starting the machine accidentally.
4. Store idle machines out of the reach
of children and do not allow persons
unfamiliar with the machine or these
instructions to operate the machine.
Machines are dangerous in the hands of
untrained users.
5. Maintain machines and accessories.
Check for misalignment or binding of
moving parts, breakage of parts and
any other condition that may affect the
machine’s operation. If damaged, have
the machine repaired before use. Many
accidents are caused by poorly maintained
machines.
6. Keep cutting machines sharp and clean.
Properly maintained cutting machines with
sharp cutting edges are less likely to bind
and are easier to control.
7. Use the machine, accessories and
machine bits etc. in accordance with
these instructions, taking into account
the working conditions and the work to
be performed. Use of the machine for
operations different from those intended
could result in a hazardous situation.
8. Keep handles and grasping surfaces
dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do
not allow for safe handling and control of the
machine in unexpected situations.
BATTERY MACHINE USE AND
CARE
1. 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 re when used with
another battery pack.
2. Use machines only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and
re.
3. When battery pack is not in use, keep
it away from other metal objects, like
paper clips, coins, keys, nails, screws or
other small metal objects, that can make
a connection from one terminal to another.
Shorting the battery terminals together may
cause burns or a re.
4. 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. Do not use a battery pack or machine
that is damaged or modified. Damaged or
modied batteries may exhibit unpredictable
behavior resulting in re, explosion or risk of
injury.
Page 6
SAFETY INSTRUCTIONS
6. Do not expose a battery pack or
machine to fire or excessive temperature.
Exposure to re or temperature above
265 °F (130 °C) may cause explosion.
7. Follow all charging instructions and do
not charge the battery pack or machine
outside the temperature range specified
in the instructions. Charging improperly or
at temperatures outside the specied range
may damage the battery and increase the
risk of re.
SERVICE
1. Have your machine serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the
safety of the machine is maintained.
2. Never service damaged battery
packs. Service of battery packs should
only be performed by the manufacturer or
authorized service providers.
STRING TRIMMER SAFETY
WARNINGS
1. Do not use the machine in bad weather
conditions, especially when there is a risk
of lightning. This decreases the risk of being
struck by lightning.
2. Thoroughly inspect the area for wildlife
where the machine is to be used. Wildlife
may be injured by the machine during
operation.
3. Thoroughly inspect the area where
the machine is to be used and remove all
stones, sticks, wires, bones, and other
foreign objects. Thrown objects can cause
personal injury.
4. Before using the machine, always
visually inspect to see that the cutter and
the cutter assembly are not damaged.
Damaged parts increase the risk of injury.
5. Follow instructions for changing
accessories. Improperly tightened blade
securing nuts or bolts may either damage
the blade or result in it becoming detached.
6. Wear eye, ear, head and hand
protection. Adequate protective equipment
will reduce personal injury by ying debris
or accidental contact with the cutting line or
blade.
7. While operating the machine, always
wear non-slip and protective footwear. Do
not operate the machine when barefoot
or wearing open sandals. This reduces the
chance of injury to the feet from contact with
the moving lines.
8. While operating the machine, always
wear long trousers. Exposed skin increases
the likelihood of injury from thrown objects.
9. Keep bystanders away while operating
the machine. Thrown debris can result in
serious personal injury.
10. Always use two hands when operating
the machine. Holding the machine with both
hands will avoid loss of control.
11. Hold the machine by the insulated
gripping surfaces only, because the cutting
line or blade may contact hidden wiring.
Cutting line or blades contacting a “live”
wire may make exposed metal parts of the
machine “live” and could give the operator
an electric shock.
12. Always keep proper footing and operate
the machine only when standing on the
ground. Slippery or unstable surfaces may
cause a loss of balance or control of the
machine.
13. Do not operate the machine on
excessively steep slopes. This reduces the
risk of loss of control, slipping and falling
which may result in personal injury.
14. When working on slopes, always be
sure of your footing, always work across
the face of slopes, never up or down and
exercise extreme caution when changing
direction. This reduces the risk of loss of
control, slipping and falling which may result
in personal injury.
15. Keep all parts of the body away from
the line when the machine is operating.
Before you start the machine, make sure
line is not contacting anything. A moment
of inattention while operating the machine
may result in injury to yourself or others.
Page 7
16. Do not operate the machine above
waist height. This helps prevent unintended
line contact and enables better control of
the machine in unexpected situations.
17. When cutting brush or saplings that
are under tension, be alert for spring
back. When the tension in the wood bers
is released, the brush or sapling may strike
the operator and/or throw the machine out
of control.
18. Use extreme caution when cutting
brush and saplings. The slender material
may catch the line and be whipped toward
you or pull you off balance.
19. Maintain control of the machine and
do not touch lines and other hazardous
moving parts while they are still in motion.
This reduces the risk of injury from moving
parts.
20. Carry the machine with the machine
switched off and away from your body.
Proper handling of the machine will reduce
the likelihood of accidental contact with a
moving line.
21. Only use replacement lines and cutting
heads specified by the manufacturer.
Incorrect replacement parts may increase
the risk of breakage and injury.
22. When clearing jammed material or
servicing the machine, make sure the
switch is off and the battery pack is
removed. Unexpected starting of the
machine while clearing jammed material
or servicing may result in serious personal
injury.
23. If you strike a foreign object with the
trimmer or it becomes entangled, stop the
machine immediately, check for damage
and have any damage repaired before
further operation is attempted. Do not
operate with a broken guard or spool.
24. If machine starts to vibrate abnormally,
stop the motor and check immediately for
the cause. Vibration is generally a warning
of trouble. A loose head may vibrate, crack,
break or come off the trimmer, which may
result in serious or fatal injury. Make sure
that the cutting attachment is properly xed

Check for blockage of the trimmer head
To prevent blockage, keep the trimmer head
clean. Remove grass clippings, leaves, dirt
and any other accumulated debris before
and after each use.
When blockage happens, stop the string
trimmer and remove the battery. Then re-
move any grass that may have wrapped it-
self around the motor shaft or trimmer head.
TIPS FOR BEST TRIMMING
RESULTS (FIG. 12)
FIG. 12
Direction of
Rotation
Best Cutting
Area
Dangerous
Cutting Area
The correct angle for the cutting
attachment is parallel to the ground.
Do not force the trimmer. Allow the very
tip of the line to do the cutting (especially
along walls). Cutting with more than the
tip will reduce cutting efciency and may
overload the motor.
The cutting height is determined by the
distance of the cutting line from the lawn
surface.
Grass over 8 in. should be cut by working
progressively from top to the bottom in small
increments to avoid premature line wear or
motor drag.
Slowly move the trimmer into and out of
the area being cut, maintaining the cutting
head position at the desired cutting height.
This movement can be either a forward-
backward motion or a side-to-side motion.
Cutting shorter lengths produces best results.
Trim only when grass and weeds are dry.
Wire and picket fences can cause extra
string wear or breakage. Stone and brick
walls, curbs, and wood may wear strings
rapidly.
Avoid trees and shrubs. Tree bark, wood
moldings, siding, and fence posts can easily
be damaged by the strings.
ADJUSTING THE CUTTING LINE
LENGTH (FIG. 13)
FIG. 13
The trimmer head allows the operator to re-
lease more cutting line without stopping the
motor. As line becomes frayed or worn, ad-
ditional line can be released by lightly tap-
ping the trimmer head on the ground while
operating the trimmer.
For best results, tap the trimmer head on bare
ground or hard soil. If line release is attempt-
ed in tall grass, the motor may overheat.
WARNING:
Always keep the
trimming line fully extended. Line release
becomes more difficult as the cutting line
becomes shorter. Do not remove or alter
the line cutting blade assembly. Excessive
line length will cause the motor to overheat
and may result in serious personal injury.
