GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings,
instructions, illustrations and specifications provided
with this power tool. Failure to follow all instructions
listed below may result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for future
reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
WORK AREA SAFETY
◾Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
◾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.
◾Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control.
PERSONAL SAFETY
◾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.
◾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.
◾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 tool. Carrying power tools with your finger on the
switch or energizing power tools that have the switch
on invites accidents.
◾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.
◾Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
◾Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair
can be caught in moving parts.
◾If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
devices can reduce dust-related hazards.
◾Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of second.
POWER TOOL USE AND CARE
◾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.
◾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.
◾Remove the battery pack, if detachable, from the
power tool and/or activate any battery disabling
device before clearing jammed material, making
any adjustments, changing accessories, cleaning, or
storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
◾Store idle power tools out of the reach of children and
do not allow persons unfamiliar with power tool or
these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
◾Maintain power tools and accessories. Check
for misalignment or building 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.
◾Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
◾Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to
be performed. Use of the power tool for operations
different from those intended could result in a
hazardous situation.
◾Keep handles and grasping surface dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
◾Keep cables away from the working area of the
tool. During operation cables may be hidden from view
and can be accidentally damaged by the tool.

56 VOLT LITHIUM-ION CORDLESS LINE TRIMMER — ST1400E-ST8
BATTERY TOOL USE AND CARE
◾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 use with
another battery pack.
◾Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
◾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 connections from one terminal to another.
Shorting the battery terminals together may cause
burns or a fire.
◾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.
◾Do not use a battery pack or tool that is damaged
or modified. Damaged or modified batteries may
exhibit unpredictable behavior resulting in fire,
explosion or risk of injury.
◾Do not expose a battery pack or tool to fire
or excessive temperature. Exposure to fire or
temperature above 100°C may cause explosion.
◾Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging
improperly or at temperatures outside the specified
range may damage the battery and increase the risk
of fire.
SERVICE
◾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.
◾Never service damaged battery packs. Service
of battery packs should only be performed by the

◾Blade thrust can be violent enough to cause the unit
and/or operator to be propelled in any direction, and
possibly lose control of the unit.
◾Blade thrust can occur without warning if the blade
snags, stalls or binds.
◾Blade thrust is more likely to occur in areas where it
is difficult to see the material being cut.
◾Do not attach any blade to a unit without proper
installation of all required parts. Failure to use the
proper parts can cause the blade to fly off and
seriously injure the operator and/or bystanders.
Discard blades that are bent, warped, cracked,
broken, or damaged in any way. Use a sharp blade.
A dull blade is more likely to snag and thrust
(only using with 3-teeth blade).
◾A coasting blade/line can cause injury while it
continues to spin after the motor is stopped or
trigger is released. Maintain proper control until
the blade/line has completely stopped rotating.
◾Use only with EGO’s battery packs and chargers.
