General power tool Safety Warnings
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.
1. Work area safety
a. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b. 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.
c. Keep children and bystanders away
while operating a power tool. Distractions
can cause you to lose control.
2. electrical safety
a. power tool plugs must match the outlet.
never modify the plug in any way. Do not use
any adapter plugs with earthed (grounded)

iF MiStreateD:
a. Keep Battery pack dry.
b. DO nOt DO any OF tHe FOLLOWinG
tO tHe Battery pacK:
• Open,
• Drop,
• Short-circuit,
• puncture,
• incinerate, or
• expose to temperatures
greater than 140°F.
c. Charge Battery Pack only according
to its Charger’s instructions.
d. Inspect Battery Pack before every use;
do not use or charge if damaged.
8. Safety instructions for all operations
a. use the auxiliary handle(s). Loss of
control can cause personal injury.
b. Brace the tool properly before use. This
tool produces a high output torque and without
properly bracing the tool during operation, loss
of control may occur resulting in personal injury.
c. Hold the power tool by insulated
gripping surfaces, when performing an
operation where the cutting accessory or
fasteners may contact hidden wiring or
its own cord. Cutting accessory contacting
a “live” wire may make exposed metal
parts of the power tool “live” and could
give the operator an electric shock.
d. Let bit cool before touching, changing
or adjusting it. Bits heat up dramatically
while in use, and can burn you.
e. If the drill bit jams, release the
Trigger immediately; drill torque
can cause injury or break bit.
9. Safety instructions when using long drill bits
a. never operate at higher speed than the
maximum speed rating of the drill bit.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting
the workpiece, resulting in personal injury.
b. always start drilling at low speed and with
the bit tip in contact with the workpiece.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting
the workpiece, resulting in personal injury.
c. apply pressure only in direct line with the
bit and do not apply excessive pressure.
Bits can bend causing breakage or loss
of control, resulting in personal injury.
10. Vibration Safety
This tool vibrates during use.
Repeated or long‑term exposure to vibration may
cause temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration‑related injury:
a. Anyone using vibrating tools regularly or for
an extended period should first be examined
by a doctor and then have regular medical
check‑ups to ensure medical problems are not
being caused or worsened from use. Pregnant
women or people who have impaired blood
circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or
Raynaud’s Disease should not use this tool.
If you feel any symptoms related to
vibration (such as tingling, numbness,
and white or blue fingers), seek medical
advice as soon as possible.
b. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration‑related injury.
c. Wear suitable gloves to reduce the
vibration effects on the user.
d. Use tools with the lowest vibration
when there is a choice.
e. Include vibration‑free periods each day of work.
f. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
g. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.

2. electrical safety
a. 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.
b. 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.
c. Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
d. 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.
e. 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.
f. 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.
g. Hold the power tool by insulated gripping
surfaces, when performing an operation
where the fastener may contact hidden
wiring or its own cord. Fasteners contacting
a “live” wire may make exposed metal
parts of the power tool “live” and could
give the operator an electric shock.

surfaces, when performing an operation
where the cutting tool may contact
hidden wiring or its own cord. Contact
with a “live” wire will also make exposed
metal parts of the power tool “live” and
could give the operator an electric shock.
f. When ripping, always use a rip fence
or straight edge guide. This improves
the accuracy of cut and reduces
the chance of blade binding.
g. 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-center, causing loss of control.
h. never use damaged or incorrect blade
washers or bolt. The blade washers and
bolt were specially designed for your saw, for
optimum performance and safety of operation.
7. 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;
- 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 the operator.
8. 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.
a. 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.
9. 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.
a. When restarting a saw in the workpiece,
centre the saw blade in the kerf so that the
saw teeth are not engaged into the material.
If a saw blade binds, it may walk up or kickback
from the workpiece as the saw is restarted.

SAFEtyOpERAtiOnMAintEnAncE SEtUp
10. 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 cut and near the edge of the panel.
a. Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
b. Blade depth and bevel adjusting locking
levers must be tight and secure before
making the cut. If blade adjustment shifts while
cutting, it may cause binding and kickback.
c. Use extra caution when sawing into existing
walls or other blind areas. The protruding
blade may cut objects that can cause kickback.
11. Lower guard function
a. check the lower guard for proper closing
before each use. Do not operate the saw
if the 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
retracting handle and make sure it moves
freely and does not touch the blade or any
other part, in all angles and depths of cut.
b. 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 build-up of debris.
c. the lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts”. Raise the lower guard
by the retracting handle and as soon as the
blade enters the material, the lower guard
must be released. For all other sawing, the
lower guard should operate automatically.
d. Always observe that the lower guard
is covering the blade before placing
the 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.
12. Riving knife function
a. Use the appropriate saw blade for the riving
knife. For the riving knife to function, the body
of the blade must be thinner than the riving
knife and the cutting width of the blade must
be wider than the thickness of the riving knife.
b. Adjust the riving knife as described in
this instruction manual. Incorrect spacing,
positioning and alignment can make the riving
knife ineffective in preventing kickback.
c. Always use the riving knife except when
plunge cutting. The riving knife must be
replaced after plunge cutting. The riving
knife causes interference during plunge
cutting and can create kickback.
d. For the riving knife to work, it must
be engaged in the workpiece. The
riving knife is ineffective in preventing
kickback during short cuts.
e. Do not operate the saw if the riving
knife is bent. Even a light interference
can slow the closing rate of a guard.
13. Battery tool use and care
a. prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to battery pack, picking up or carrying the
power tool. Carrying the power tool with your
finger on the switch or energizing power tool
that have the switch on invites accidents.
b. Disconnect the battery pack from the
power tool before making any adjustments,
changing accessories, or storing power
tool. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
c. 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.
d. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
e. 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.
f. 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.
g. Do not use a battery pack or power tool that
is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
h. Do not expose a battery pack or power
tool to fire or excessive temperature.
Exposure to fire or temperature above
140°F may cause explosion.

i. Follow all charging instructions and do
not charge the battery pack or power tool
outside of the temperature range specified
in the instructions. Charging improperly or at
temperatures outside of the specified range may
damage the battery and increase the risk of fire.
j. Have servicing performed by a qualified
repair person using only identical
replacement parts. This will ensure that
the safety of the product is maintained.
k. Do not modify or attempt to repair the power
tool or the battery pack except as indicated
in the instructions for use and care.
l. The battery Charger gets hot during
use. The Charger’s heat can build
up to unsafe levels and create a fire
hazard if it does not receive
adequate ventilation, due to an electrical fault, or
if it is used in a hot environment. Do not place
the Charger on a flammable surface. Do not
obstruct any vents on the Charger.
Especially avoid placing the charger on
carpets and rugs; they are not only
flammable, but they also obstruct vents
under the charger. Place the Charger on a
stable, solid, nonflammable surface (such as a
stable metal workbench or concrete floor) at
least 1 foot away from all flammable objects,
such as drapes or walls. Keep a fire
extinguisher and a smoke detector in the area.

Vibration Safety
This tool vibrates during use.
Repeated or long‑term exposure to vibration may
cause temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration‑related injury:
1. Anyone using vibrating tools regularly or for
an extended period should first be examined
by a doctor and then have regular medical
check‑ups to ensure medical problems are not
being caused or worsened from use. Pregnant
women or people who have impaired blood
circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or
Raynaud’s Disease should not use this tool.
If you feel any symptoms related to vibration (such
as tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration‑related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration‑free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.

Page 3For technical questions, please call 1-888-866-5797.Item 58379
SaFetyOperatiOnMaintenance Setup
2. electrical safety
a. 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.
b. 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.
c. Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
d. 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.
e. 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.
f. 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.
3. personal safety
a. 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

e. Do not overreach. Keep proper
footing and balance at all times. This
enables better control of the power
tool in unexpected situations.
f. 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.
g. 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.
h. 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.
i. Only use safety equipment that has been
approved by an appropriate standards agency.
Unapproved safety equipment may not provide
adequate protection. Eye protection must be
ANSI‑approved and breathing protection
must be NIOSH‑approved for the
specific hazards in the work area.
j. Do not lay the tool down until it has come to
a complete stop. Moving parts can grab the
surface and pull the tool out of your control.
k. When using a handheld power
tool, maintain a firm grip.
l. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.
m. This product is not a toy.

consult their physician(s) before use.
Electromagnetic fields in close proximity to
heart pacemaker could cause pacemaker
interference or pacemaker failure.
o. The warnings, precautions, and instructions
discussed in this instruction manual cannot
cover all possible conditions and situations
that may occur. It must be understood by the
operator that common sense and caution are
factors which cannot be built into this product,
but must be supplied by the operator.
4. power tool use and care
a. 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.
b. Do not use the power tool if the switch

tool that cannot be controlled with the switch
is dangerous and must be repaired.
Page 4 For technical questions, please call 1-888-866-5797. Item 58379
SaFety OperatiOn MaintenanceSetup
c. 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.
d. 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.
e. 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.
f. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g. 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.

accessory contacting a “live” wire may make
exposed metal parts of the power tool “ live”
and could give the operator an electric shock.
b. use clamps or another practical way to
secure and support the workpiece to a
stable platform. Holding the workpiece
by hand or against your body leaves it
unstable and may lead to loss of control.
7. Belt sander and drum sander safety warnings
a. Hold the power tool by insulated gripping
surfaces, because the sanding surface
may contact its own cord. Cutting a
“live” wire may make exposed metal
parts of the power tool “live” and could
give the operator an electric shock.
8. Battery tool use and care
a. prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to battery pack, picking up or carrying the
power tool. Carrying the power tool with your

d. use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
e. 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.
f. 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.
g. Do not use a battery pack or power tool that
is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
h. Do not expose a battery pack or power
tool to fire or excessive temperature.

IMpORTANT SAFETy INFORMATION
General power Tool Safety Warnings
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions 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 battery-operated (cordless) power tool.
Work Area Safety
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders
away while operating a power tool.
Distractions can cause you to lose control.

SAFETyOpERATIONMAINTENANcE SETUp
Electrical Safety
Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
personal Safety
1. 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.
2. 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.
3. prevent unintentional starting.
Ensure the Switch is in the off-position before
connecting to power source, 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.
4. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
5. 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.
6. 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.
7. Only use safety equipment that has been
approved by an appropriate standards agency.
Unapproved safety equipment may not provide
adequate protection. Eye protection must be
ANSI-approved and breathing protection
must be NIOSH-approved for the
specific hazards in the work area.
power Tool Use and care
1. 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.
2. 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.
3. Disconnect the battery pack 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.
4. 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.
5. Maintain power tools. 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.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7. 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.
Battery tool 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 fire when used with another battery pack.
2. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
Page 4 For technical questions, please call 1-888-866-5797. Item 63628
SAFETy OpERATION MAINTENANcESETUp
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 fire.
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.
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.
Flashlight Safety Warnings
1. Do not shine directly into eyes
of people or animals.
2. Not a toy; keep away from children.
