GENERAL POWER TOOL SAFETY WARNINGS
WARNING! Read all safety warnings, instructions, illustrations and
specications 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 ammable 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 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.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1610/CS1610-FC8
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 inuence 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
energising 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 jewellery. Keep your hair,
and clothing away from moving parts. Loose clothes, jewellery 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.
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.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1610/CS1610-FC 9
◾Disconnect the plug from the power source and/or remove the battery
pack, if detachable, 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 do not allow for safe handling
and control of the tool in unexpected situations.
Battery tool use and care
◾Recharge only with the charger specied 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.
◾Use power tools only with specically 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 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, ush with water. If liquid
contacts eyes, additionally seek medical help. Liquid ejected from the
battery may cause irritation or burns.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1610/CS1610-FC10
◾Do not use a battery pack or tool that is damaged or modied. Damaged
or modified batteries may exhibit unpredictable behaviour resulting in fire,
explosion or risk of injury.
◾Do not expose a battery pack or tool to re or excessive temperature.
Exposure to fire or temperature above 265 °F may cause explosion.
◾Follow all charging instructions and do not charge the battery pack or
tool outside the temperature range specied 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 qualied 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 manufacturer or authorized service providers
CHAIN SAW SAFETY WARNINGS
◾Keep all parts of the body away from the saw chain when the chain saw
is operating. Before you start the chain saw, make sure that the saw
chain is not contacting anything. A moment of inattention while operating
chain saws may cause entanglement of your clothing or body with the chain.
◾Always hold the chain saw with your right hand on the rear handle and
your left hand on the front handle. Holding the chain saw with a reversed
hand configuration increases the risk of personal injury and should never be done.
◾Hold the chain saw 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 chain saw "live" and could give
the operator an electric shock.
◾Wear eye protection. Further protective equipment for hearing, head,
hands, legs and feet is recommended. Adequate protective equipment will
reduce personal injury from flying debris or accidental contact with the saw chain.
◾Do not operate a chain saw in a tree, on a ladder, from a rooftop, or
any unstable support. Operation of a chain saw in this manner could result in
serious personal injury.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1610/CS1610-FC 11
◾Always keep proper footing and operate the chain saw only when
standing on xed, secure and level surface. Slippery or unstable surfaces
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 chain saw 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 chain saw by the front handle with the chain saw switched off
and away from your body. When transporting or storing the chain saw,
always t the guide bar cover. Proper handling of the chain saw will reduce
the likelihood of accidental contact with the moving saw chain.
◾Follow instructions for lubricating, chain tensioning and changing the
bar and chain. Improperly tensioned or lubricated chain may either break or
increase the chance for kickback.
◾Cut wood only. Do not use chain saw for purposes not intended. For
example: do not use chain saw for cutting metal, plastic, masonry or
non-wood building materials. Use of the chain saw for operations different
than intended could result in a hazardous situation.
◾Do not attempt to fell a tree until you have an understanding of the
risks and how to avoid them. Serious injury could occur to the operator or
bystanders while felling a tree.
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 chain saw user, you should take several steps to keep
your cutting jobs free from accident or injury.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1610/CS1610-FC12
◾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 rm grip, with thumbs and ngers encircling the chain saw
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 chain saw.
◾Do not overreach and do not cut above shoulder height. This helps prevent
unintended tip contact and enables better control of the chain saw in unexpected
situations.
◾Only use replacement bars and chains specied 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.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1610/CS1610-FC 13
KICKBACK SAFETY DEVICES ON THIS CHAIN SAW
Chain Brake
The chain saw comes equipped with a chain brake, which stops both the motor and
the motion of the chain when kickback occurs. The chain brake can be activated by the
forward motion of the chain kickback brake handle as the saw rotates backward during
kickback.
WARNING:Never modify or attempt to disable the chain brake.
Make sure that the chain brake is working properly before using the chain saw. The
chain kickback brake handle should move back and forth easily.
To test the operation of the chain brake,
perform the following steps (Fig. 1):
◾Place the chain saw on a flat bare
surface and make sure no objects
or obstructions that could come in
contact with the bar and chain are in
the immediate vicinity.
◾Disengage the chain brake by
pulling the chain kickback brake
handle towards the front handle.
◾Start the chain saw.
◾Push the chain kickback brake handle towards the front of the saw. A properly
functioning hand brake will stop the movement of the chain immediately. If the
chain brake is not working properly, do not use the chain saw until it has been
repaired by a qualified service technician.

WARNING:Conrm that the chain brake works properly before each use.
WARNING:If the chain brake is clogged with wood chips, the function
of the chain brake may deteriorate. Always keep the device clean.
Low Kickback Saw Chain
The rakers (depth gauges) ahead of
each cutter can minimize the force of
a kickback reaction by preventing the
cutters from digging in too deeply at the
kickback zone. Only use a replacement
chain that is equivalent to the original
chain or has been certified as a low
kickback chain per ANSI B175.1. A low
kickback tooth saw chain is a chain that
has met the kickback performance requirements of ANSI B175.1 (American National
Standard for Power Tools - Gasoline-Powered Chain Saws-Safety Requirements) when
tested on the representative sample of chain saws below 3.8 c.i.d. specified in ANSI
B175.1.
The bumper drive link (Fig. 2) also helps deliver low-kickback performance.
CAUTION: As saw chains are sharpened during their useful life, they lose some
of the low kickback qualities and extra caution should be used.
GUIDE BAR
This saw comes equipped with a guide bar that has a small radius nose. Small radius
noses generally have less potential for kickback. When replacing the guide bar, please
order the guide bar we recommend in this manual or the guide bar with the correct
specification with regarding to this product.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1610/CS1610-FC 15
ADDITIONAL WARNINGS
◾A chain saw is intended for
two-handed use (Fig. 3). Serious
injury to the operator, helpers, and/
or bystanders can result from one-
handed operation.
◾Make sure that the area in
which you are cutting is free
from obstructions. Do not let
the nose of the guide bar contact
a log, branch, fence, or any other
obstruction that could be hit while
you are operating the saw.
◾Always cut with the unit running
at full speed. Fully squeeze the
switch trigger and maintain cutting
speed.
◾With a basic understanding
of kickback, you can reduce
or eliminate the element of
surprise (Fig.4 – Fig. 6). Sudden
surprise contributes to accidents.
◾Keep proper footing and balance
at all times.
◾Avoid unintentional contact
with the stationary saw chain or
guide bar rails. These can be very
sharp. Always wear gloves and long
pants or chaps when handling the
chain saw, saw chain, or guide bar.
◾Never operate a chain saw
that is damaged or improperly
adjusted or that is not
completely and securely
assembled. Be sure that the saw
chain stops moving when the trigger
switch is released.

◾Inspect the work piece for nails, wire, or other foreign objects prior to
cutting. When bucking, secure the work piece prior to cutting. When
felling or pruning, identify and secure hazardous branches.
◾Aggressive or abusive cutting or misuse of the chain saw can cause
premature bar, chain, and/or sprocket wear, as well as a broken chain or
bar, leading to kickback, chain throw or the ejection of material.
◾Never use the guide bar as a lever. A bent guide bar can cause premature
bar, chain, and/ or sprocket wear, as well as a broken chain or bar, leading to
kickback, chain throw or the ejection of material.
Cut only one work piece at a
time.
◾Push and Pull – The reaction force
is always opposite to the direction
the chain is moving where wood
contact is made. Thus, the operator
must be ready to control the PULL
when cutting on the bottom edge of
the bar, and the PUSH when cutting
along the top edge. See Fig 7.
◾Plan the work, ensuring an
obstacle-free work area and, in
the case of felling, at least one
escape path from the falling
tree.
◾When felling, keep bystanders at
least two tree lengths away.
◾Do not incinerate the appliance
even if it is severely damaged.
The batteries can explode in a fire.
