TECHNICAL SPECIFICATIONS GENERAL POWER TOOL SAFETY WARNINGS
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.
ELECTRICAL SAFETY
• Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adaptor 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 Residual
Current Device (RCD) protected supply. Use of an RCD reduces the risk of electric
shock.
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.

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 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,
clothing and gloves 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.
• 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 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.
• 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 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 use a battery pack or tool that is damaged or modified. 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 fire or excessive temperature. Exposure
to fire or temperature above 130 °C (266°F) may cause explosion.
• Follow all charging instructions and do not charge the battery pack or

• When the blade is pinched or jammed tightly by the kerf closing down, the blade
stalls and the motor reaction drives the unit rapidly back toward the operator.
• If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of
the blade can dig into the top surface of the wood causing the blade to climb out of
the kerf and jump back toward operator.
Kickback is the result of saw misuse and/or incorrect operating procedures or conditions
and can be avoided by taking proper precautions as given below:
• Maintain a firm grip with both hands on the saw and position your arms to
resist kickback forces. Position your body to either side of the blade, but not in
line with the blade. Kickback could cause the saw to jump backwards, but kickback
forces can be controlled by the operator, if proper precautions are taken.
• When blade is binding, or when interrupting a cut for any reason, release the
trigger and hold the saw motionless in the material until the blade comes to a
complete stop. Never attempt to remove the saw from the work or pull the saw
backward while the blade is in motion or kickback may occur. Investigate and
take corrective actions to eliminate the cause of blade binding.
• When restarting a saw in the workpiece, centre the saw blade in the kerf and
check that saw teeth are not engaged in the material. If saw blade is binding, it
may walk up or kick back from the workpiece as the saw is restarted.
• Support large panels to minimise the risk of blade pinching and kickback. Large
panels tend to sag under their own weight. Supports must be placed under the
panel on both sides, near the line of the cut and near the edge of the panel.
• Do not use dull or damaged blade. Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade binding and kickback.
• Blade depth and bevel adjusting locking levers must be tight and secure before
making cut. If blade adjustment shifts while cutting, it may cause binding and
kickback.
• Use extra caution sawing into existing walls or other blind areas. The protruding
blade may cut objects that can cause kickback.
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 manufacturer or authorized service providers.
SAFETY INSTRUCTIONS FOR ALL SAWS
• Do not reach underneath the workpiece. The guard cannot protect you from the
blade below the workpiece.
• Adjust the cutting depth to the thickness of the workpiece. Less than a full
tooth of the blade teeth should be visible below the workpiece.
• Never hold the workpiece in your hands or across your leg while cutting.
Secure the workpiece to a stable platform. It is important to support the work
properly to minimize body exposure, blade binding, or loss of control.
• Hold power tool by insulated gripping surfaces when performing an operation
where the cutting tool may contact hidden wires. Contact with a “live” wire will
also make exposed metal parts of the power tool “live” and could give the operator
an electric shock.
• When ripping, always use a rip fence or straight edge guide. This improves the
accuracy of cut and reduces the chance of blade binding.
• Always use blades with correct size and shape (diamond versus round) of
arbor holes. Blades that do not match the mounting hardware of the saw will run
off-centre, causing loss of control.
• Never use damaged or incorrect blade washers or bolts. The blade washers and
bolts were specially designed for your saw, for optimum performance and safety of
operation.
FURTHER SAFETY INSTRUCTIONS FOR ALL SAWS
Kickback causes and related warnings
• Kickback is a sudden reaction to a pinched, jammed or misaligned saw blade,
causing an uncontrolled saw to lift up and out of the workpiece toward the
operator.
SAFETY INSTRUCTIONS SAFETY INSTRUCTIONS
WARNING!
Do not use abrasive wheels or blades.
WARNING!
Do not use water feed attachments.
CAUTION!
Do not attempt to cut stainless steel, rebar, hardened or
heat-treated steel, cast iron, masonry or unknown materials.
model no. 054-8355-0 | contact us 1-888-670-6682
DANGER!
Keep hands away from cutting area and blade. Keep your
second hand on auxiliary handle or motor housing. If both
hands are holding the saw, they cannot be cut by the blade.

10 11
Lower guard function
• Check the lower guard for proper closing before each use. Do not operate saw
if lower guard does not move freely and close instantly. Never clamp or tie the
lower guard into the open position. If the saw is accidentally dropped, the lower
guard may be bent. Raise the lower guard with the lower guard lever and make sure
it moves freely and does not touch the blade or any other part, in all angles and
depths of cut.
• Check the operation of the lower guard spring. If the guard and the spring are
not operating properly, they must be serviced before use. Lower guard may
operate sluggishly due to damaged parts, gummy deposits, or a buildup of debris.
• The lower guard may be retracted manually only for special cuts such as
“plunge cuts” and “compound cuts”. Raise the lower guard by lower guard
lever, and as soon as blade enters the material the lower guard must be
released. For all other sawing, the lower guard should operate automatically.
• Always observe that the lower guard is covering the blade before placing saw
down on bench or floor. An unprotected, coasting blade will cause the saw to
walk backwards, cutting whatever is in its path. Be aware of the time it takes for the
blade to stop after switch is released.
ADDITIONAL SPECIFIC SAFETY INSTRUCTIONS FOR CIRCULAR SAWS
• Use clamps or another practical way to secure and support the workpiece to a
stable platform. Holding the work by hand or against your body leaves it unstable
and may lead to loss of control.
• Keep your body positioned to either side of the blade, but not in line with
the saw blade. Kickback could cause the saw to jump backwards (see Causes and
Operator Prevention of Kickback and Kickback).
• Air vents often cover moving parts and should be avoided. Loose clothes,
jewellery or long hair can be caught in moving parts.
• Avoid cutting nails. Inspect for and remove all nails from lumber before cutting.
• Avoid prolonged contact with dust from power sanding, sawing, grinding,
drilling, and other construction activities.
• Wear protective clothing and wash exposed areas with soap and water.
Allowing dust to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.
SAFETY RULES FOR BATTERY PACK AND CHARGER
• If the battery pack casing is cracked or damaged, do not insert into charger. There is
a danger of electric shock or electrocution.
• Don’t allow any liquid to get inside charger. Electric shock may result. To facilitate
cooling of the battery pack after use, avoid placing the charger or battery pack in a
warm environment such as in a metal shed, or a trailer that is not insulated.
• This charger is not intended for any uses other than charging rechargeable batteries.
Any other use may result in risk of fire, electric shock or electrocution.
• Do not place any object on top of the charger or place the charger on a soft surface.
This may result in excessive internal heat. Do not place the charger near any heat
source.
• To reduce the potential risk of damage to the electric plug and cord, pull by the plug
rather than the cord when disconnecting the charger from the power supply.
• Make sure the cord is located so it will not be stepped on, tripped over, or otherwise
subjected to damage or stress.

ADDITIONAL INFORMATION ON BATTERY AND CHARGER
• The battery pack is not fully charged out of the carton. First read the safety
instructions and then follow the charging notes and procedures.
• The longest life and best performance can be obtained if the battery pack is
charged when the air temperature is 15–25°C (59–77°F). Do not charge the battery
pack where the air temperature is below 0°C (32°F) or above 45°C (113°F). This is
important and will prevent damage to the battery pack.
• Do not incinerate the battery pack even if it is seriously damaged or is completely
worn out. The battery can explode in a fire.
• Never attempt to open the battery pack for any reason. If the plastic housing of the
battery pack breaks or cracks, immediately discontinue use and do not recharge.
• The length of service from your battery will depend on the type of work you
are doing. The battery has been designed to provide maximum trouble-free life.
However, like all batteries, it will eventually wear out.
• To obtain the longest possible battery life, we suggest the following:
- Store and charge your battery in a cool area. Temperatures above or below
normal room temperature will shorten battery life.
- Never store the battery in a discharged condition. Recharge it immediately after
it has been discharged.
• All batteries gradually lose their charge. The higher the temperature, the quicker
they lose their charge. If you store your tool for long periods of time without use,
recharge the battery every month or two. This practice will prolong battery life.
