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.
Electrical Safety
• 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 the risk of electric
shock.
• 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.
• Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
• 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.
• 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.
• If operating a power tool in a damp location is unavoidable, use a ground
fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces
the risk of electric shock.
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, ill, 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 dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate conditions will reduce
personal injuries.

DCS-2500T SAFETY
X7508220200 11

• Prevent unintentional starting. Ensure the switch is in the off-position
before connecting to power source and/or battery, 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
collection 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 a second.
Proper Clothing
Wear snug-fitting, durable clothing:
• Pants should have long legs, shirts should have long sleeves.
• DO NOT WEAR SHORTS.
• DO NOT WEAR TIES, SCARVES, JEWELRY, or clothing with loose or
hanging items that could become entangled in moving parts or
surrounding growth.
• Keep clothing buttoned or zipped, and keep shirt tails tucked in.
• Wear sturdy work shoes with nonskid rubber soles.
• DO NOT WEAR OPEN TOED SHOES.
• DO NOT OPERATE UNIT WITH BARE FEET.
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.

SAFETY DCS-2500T

• Disconnect the plug from the power source and/or the battery from the
power tool before making any adjustments, changing accessories, 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 the 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 binding
of moving parts, breakage of parts and any other condition that may affect
the power tool’s 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 surfaces dry, clean, and free from oil and
grease. Slippery handles and grasping surfaces to not allow for safe
handling and control of the tool in unexpected situations.
Battery Tool Use and Care
• Recharge only with ECHO eFORCE™ 56V battery series chargers. A
charger that is suitable for one type of battery may create a risk of fire
when used with another battery.
• Use only with ECHO eFORCE™ 56V battery series. Use of any other
battery may create a risk of injury and fire.
• When battery 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 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 open or destroy the battery. Electrolytes contained within the
battery are corrosive and may cause damage to eyes or skin if released.
It may be toxic if swallowed.

DCS-2500T SAFETY

Discard all toxic materials in a specified manner to prevent
contamination of the environment. Before discarding a
damaged or worn out Li-ion battery, contact your local waste
disposal agency, or the local Environmental Protection Agency
for information and specific instructions. Take the batteries to a
local recycling and/or disposal center, certified for lithium-ion
disposal.
If the battery cracks or breaks, with or without leaks, do not
recharge it and do not use. Discard it and replace with a new
battery. DO NOT TRY TO REPAIR IT! To prevent injury and risk
of fire, explosion, or electric shock, and to avoid damage to
the environment:
• Cover the terminals of the battery with heavy-duty adhesive tape.
• DO NOT try to remove or destroy any of the battery components.
• DO NOT try to open the battery.
• If a leak develops, the released electrolytes are corrosive and toxic. DO
NOT get the solution in the eyes or on skin, and do not swallow it.
• DO NOT put these batteries in your regular household trash.
• DO NOT incinerate.
• DO NOT put them where they will become part of any waste landfill or
municipal solid waste stream.
• Take them to a certified recycling or disposal center.
Chainsaw Safety Warnings
• Keep all parts of the body away from the saw chain when the chainsaw is
operating. Before you start the chainsaw, make sure the saw chain is not
contacting anything. A moment of inattention while operating chainsaws
may cause entanglement of your clothing or body with the saw chain.

DCS-2500T SAFETY
X7508220200 15
© 10/21 ECHO Incorporated
• Always hold the chainsaw with your right hand on the rear handle and
your left hand on the front handle. Holding the chainsaw with a reversed
hand configuration increases the risk of personal injury and should never
be done.
• Hold the power tool by insulated gripping surfaces only, because the saw
chain may contact hidden wiring or its own cord. Saw chains contacting a
"live" wire may make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
• Wear safety glasses and hearing protection. Further protective equipment
for head, hands, legs and feet is recommended. Adequate protective
clothing will reduce personal injury by flying debris or accidental contact
with the saw chain.
• Always keep proper footing and operate the chainsaw only when standing
on fixed, secure and level surface. Slippery or unstable surfaces such as
ladders may cause a loss of balance or control of the chain saw.
• When cutting a limb that is under tension be alert for spring back. When
the tension in the wood fibres is released the spring loaded limb may
strike the operator and/or throw the chainsaw out of control.
• Use extreme caution when cutting brush and saplings. The slender
material may catch the saw chain and be whipped toward you or pull you
off balance.
• Carry the chainsaw by the front handle with the chainsaw switched off
and away from your body. When transporting or storing the chainsaw
always fit the guide bar cover. Proper handling of the chainsaw will
reduce the likelihood of accidental contact with the moving saw chain.
• Follow instructions for lubricating, chain tensioning and changing
accessories. Improperly tensioned or lubricated chain may either break or
increase the chance for kickback.
• Keep handles dry, clean, and free from oil and grease. Greasy, oily
handles are slippery causing loss of control.
• Cut wood only. Do not use chainsaw for purposes not intended. For
example: do not use chainsaw for cutting plastic, masonry or non-wood
building materials. Use of the chainsaw for operations different than
intended could result in a hazardous situation.
Using improper replacement components or removing safety
devices may result in serious or fatal injury.

SAFETY DCS-2500T
16 X7508220200
© 10/21 ECHO Incorporated
Unit includes safety devices that reduce the likelihood of
kickback:
◆Chain brake - brake actuated by kickback energy, not
manual activation.
◆Reduced-kickback guide bar - reduced nose radius guide
bar.
◆Low-kickback saw chain - saw chain that meets ANSI
kickback performance requirements when configured with
the bar/chain recommendations in this manual.
◆Front hand guard - a structural barrier between the front
handle of a chain saw and the guide bar.
Causes and Operator Prevention of Kickback
Kickback may occur when the nose or tip of the guide bar touches an
object, or when the wood closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden reverse reaction, kicking
the guide bar up and back towards the operator. Pinching the saw chain
along the top of the guide bar may push the guide bar rapidly back towards
the operator. Either of these reactions may cause you to lose control of the
saw which could result in serious personal injury. Do not rely exclusively
upon the safety devices built into your saw. As a chainsaw user, you
should take several steps to keep your cutting jobs free from accident or
injury. Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper precautions
as given below:
• Maintain a firm grip, with thumbs and fingers encircling the chainsaw
handles, with both hands on the saw and position your body and arm to
allow you to resist kickback forces. Kickback forces can be controlled by
the operator, if proper precautions are taken. Do not let go of the
chainsaw.
• Do not overreach and do not cut above shoulder height. This helps
prevent unintended tip contact and enables better control of the chainsaw
in unexpected situations.
• Only use replacement bars and chains specified by the manufacturer.
Incorrect replacement bars and chains may cause chain breakage and/or
kickback.
• Follow the manufacturer’s sharpening and maintenance instructions for
the saw chain. Decreasing the depth gauge height can lead to increased
kickback.

DCS-2500T SAFETY
X7508220200 17

Kickback Safety Precautions
Kickback safety precaution for chainsaw users: kickback may occur
when the nose or tip of the guide bar touches an object or when the
wood closes in and pinches the saw chain in the cut.
• In some cases, tip contact may
cause a lightning-fast reverse
reaction, kicking the guide bar up
and back toward the operator
(this is called a rotational
kickback). Pinching the saw chain
along the top of the guide bar may
push the guide bar rapidly back
toward the operator (this is called
a linear kickback).
• Either or these reactions may
cause you to lose control of the
saw and come in contact with the
moving chain, which could result
in serious personal injury. As a
chainsaw user, you should take
several steps to keep your cutting
jobs free from accident or injury.
• With a basic understanding of
kickback, you can reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents. Understand that rotational kickback is
preventable by keeping an unshielded bar nose from touching an object
or the ground.
• Do not operate a chainsaw with one hand! Serious injury to the operator,
helpers or bystanders may result from one-handed operation. For proper
control, always use two hands when operating a chainsaw, one of which
operates the trigger. Otherwise, this can result in the chain saw "skating"
or skidding, which can result in personal injury due to loss of control.
• Keep a good firm grip on the saw
which both hands, with the right
hand on the rear handle and the
left hand on the front handle,
when the unit is running. Use a
firm grip with thumbs and fingers
encircling the chainsaw handles.
A firm grip will help you reduce
kickback and maintain control of
the saw. Two hands must be used
to control the saw at all times.

SAFETY DCS-2500T
18 X7508220200
© 10/21 ECHO Incorporated
• Make sure that the area in which you are cutting is free from obstructions.
Do not let the bar nose contact a log, branch, or any other obstruction
which could be hit while you are operating the saw.
• Cutting at high speeds may reduce the likelihood of kickback. But cutting
at part-throttle or low speeds may be preferable to control the chainsaw in
tight situations and may also reduce the likelihood of kickback.

Vibration and Cold
It is believed that a condition called Raynaud's Phenomenon which affects
the fingers of certain individuals may be brought about by exposure to
vibration and cold. Exposure to vibration and cold may cause tingling and
burning, followed by loss of color and numbness in the fingers.
The following precautions are strongly recommended because the
minimum exposure which might trigger the ailment is unknown.
• Keep your body warm, especially the head and neck, feet and ankles,
and hands and wrists.
• Maintain good blood circulation by performing vigorous arm exercises
during frequent work breaks.
• Limit the number of hours of operation. Try to fill each day with jobs where
operating the chain saw or other hand-held power equipment is not
required.
