General Safety Rules
Read all instructions. Failure to follow all instructions listed below may result in electric shock,
fi re and/or serious injury. The term "power tool" in all of the warnings listed below refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
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
fl ammable 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
anyadapter plugs with earthed (grounded) power tools. Unmodifi ed plugs and matching
outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, rang-
es 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. Use only 3-wire extension cords that
have 3-prong grounding-type plugs and 3-pole receptacles that accept the tool's plug.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor
use. If an extension cord is to be used outdoors, it must be marked with the suffi x W-A or
W following the cord type designation. Use of a cord suitable for outdoor use reduces the
risk of electric shock. When using an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. The following table shows the correct size to use
depending on cord length and nameplate ampere rating. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier the cord.
LENGTH OF CORD IN FEET 25 50
AWG SIZE OF CORD 18 18
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 infl uence of drugs, al-
cohol or medication. A moment of inattention while operating power tools may result in
serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate condi-
tions will reduce personal injuries.
c) Avoid accidental starting. Be sure the switch is in the off-position before plugging in.
Carrying power tools with your fi nger on the switch or plugging in power tools that have the
switch on invites accidents.
d) 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.
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 mov-
ing parts.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of these devices can reduce dust-
related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The cor-
rect 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 does not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source 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. Check for misalignment or binding of moving parts, breakage
of parts and any other condition that may affect the power tools operation. If dam-
aged, 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 instruc-
tions and in the manner intended for the particular type of power tool, taking into ac-
count 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.
5) Battery tool use and care
a) Ensure the switch is in the off position before inserting battery pack. Inserting
the battery pack into power tools that have the switch on invites accidents.
b) 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.
c) Use power tools only with specifically designated battery packs. Use of any
other battery packs may create a risk of injury and fire.
d) 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.
e) Under abusive conditions, liquid may be ejected from the battery. Avoid contact.
If contact accidentally occurs, flush with water. If liquid contacts eyes, seek
additional medical help. Liquid ejected from the battery may cause irritation or
burns.
6) Service
a) 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.
ADDITIONAL SPECIFIC SAFETY RULES
Safety Instructions for All Saws
•
a) Keep hands away from cutting area and the 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.
b) Do not reach underneath the workpiece. The guard cannot protect you from the blade
below the workpiece.
c) 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.
d) Never hold piece being cut in your hands or across your leg. 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.
e) Hold power tool by insulated gripping 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 shock the operator.
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 eccentrically, 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.
Kickback Safety Instructions
Causes and Operator Prevention of Kickback:
– Kickback is a sudden reaction to a pinched, bound 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 bound 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.
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:
i) 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.
j) 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
to eliminate the cause of blade binding.
k) When restarting a saw in the workpiece, centre the saw blade in the kerf and check
that saw teeth are not engaged into the material. If saw blade is binding, it may walk up
or kickback from the workpiece as the saw is restarted.
l) Support large panels to minimize 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.
m)Do not use dull or damaged blades. Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade binding and kickback.
n) 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.
o) Use extra caution when making a "plunge cut" into existing walls or other blind areas.
The protruding blade may cut objects that can cause kickback.
Lower Guard Safety Instructions
p) Check lower guard for proper closing before each use. Do not operate the saw if
lower guard does not move freely and close instantly. Never clamp or tie the lower
guard into the open position. If saw is accidentally dropped, 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.
q) 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.
r) Lower guard should be retracted manually only for special cuts such as "plunge cuts"
and "compound cuts." Raise lower guard by retracting handle and as soon as blade
enters the material, the lower guard must be released. For all other sawing, the lower
guard should operate automatically.
s) 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.
Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• lead from lead-based paint.
• crystalline silica from bricks and cement and other masonry products.
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to filter out microscopic particles.
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.
Use of this tool can generate and/or disburse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.
ALWAYS USE SAFETY GLASSES.(ANSI Z87.1) and (CAN/CSA Z94.3) Everyday eye-
glasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS
WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3)
• ANSI S12.6 (S3.19) hearing protection
• NIOSH/OSHA/MSHA respiratory protection

IMPORTANT SAFETY INSTRUCTIONS FOR BATTERY PACKS
The battery pack is not fully charged out of the carton. Before using the battery pack and charger, read
the safety instructions below. Then follow charging procedures outlined.
• Do not incinerate the battery pack even if it is severely damaged or is completely worn out
The battery pack can explode in a fire.
• A small leakage of liquid from the battery pack cells may occur under extreme usage or
temperature conditions. This does not indicate a failure. However, if the outer seal is broken and
this leakage gets on your skin:
a. Wash quickly with soap and water.
100 150
b. Neutralize with a mild acid such as lemon juice or vinegar.
18 16
c. If battery liquid gets into your eyes, flush them with clean water for a minimum of 10
minutes and seek immediate medical attention. (Medical note: The liquid is 25-35% solution
of potassium hydroxide.)
• Charge the battery packs only in Porter-Cable chargers.
• DO NOT splash or immerse in water or other liquids.
• Do not store or use the tool and battery pack in locations where the temperature may reach
or exceed 105°F (such as outside sheds or metal buildings in summer).
• Electrocution hazard. Never attempt to open the battery pack for any reason. If battery
pack case is cracked or damaged, do not insert into charger. Electric shock or electrocution may
result. Damaged battery packs should be returned to service center for recycling.
• Fire hazard. Do not store or carry battery so that metal objects can contact exposed
battery terminals. For example, do not place battery in aprons, pockets, tool boxes, product kit boxes,
drawers, etc., with loose nails, screws, keys, etc. Transporting batteries can possibly cause fires if the
battery terminals inadvertently come in contact with conductive materials such as keys, coins,
hand tools and the like. The US Department of Transportation Hazardous Material Regulations (HMR)
actually prohibit transporting batteries in commerce or on airplanes (i.e., packed in suitcases and carry-
on luggage) UNLESS they are properly protected from short circuits. So when transporting individual
batteries, make sure that the battery terminals are protected and well insulated from materials that could
contact them and cause a short circuit.
The RBRC™ Seal
The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on the nickel cad-
mium and nickel metal hydride batteries (or battery packs) indicate that the costs to
recycle these batteries (or battery packs) at the end of their useful life have already
been paid by DeWALT. In some areas, it is illegal to place spent nickel cadmium and
nickel metal hydride batteries in the trash or municipal solid waste stream and the
RBRC program provides an environmentally conscious alternative.
RBRC™ in cooperation with Porter-Cable and other battery users, has established programs in
the United States and Canada to facilitate the collection of spent nickel cadmium and nickel metal
hydride batteries. Help protect our environment and conserve natural resources by returning the
spent nickel cadmium and nickel metal hydride batteries to an authorized DeWALT service center or
to your local retailer for recycling. You may also contact your local recycling center for information
on where to drop off the
spent battery.
RBRC™ is a registered trademark of the Rechargeable Battery Recycling Corporation.
IMPORTANT SAFETY INSTRUCTIONS FOR BATTERY CHARGERS
SAVE THESE INSTRUCTIONS: This manual contains important safety instructions for battery chargers.
• Before using charger, read all instructions and cautionary markings on charger, battery pack, and prod-
uct using battery pack.
• Electrocution hazard. 120 volts are present at charging terminals. Do not probe with con-
ductive objects.
• Shock hazard. Do not allow any liquid to get inside charger.
• Burn hazard. To reduce the risk of injury, charge only P
rechargeable batteries. Other types of batteries may burst causing personal injury and damage.
• Under certain conditions, with the charger plugged in to the power supply, the exposed
charging contacts inside the charger can be shorted by foreign material. Foreign materials of a conductive
nature such as, but not limited to, steel wool, aluminum foil, or any buildup of metallic particles should
be kept away from charger cavities. Always unplug the charger from the power supply when there is no
battery pack in the cavity. Unplug charger before attempting to clean.
• DO NOT attempt to charge the battery pack with any chargers other than the ones listed in this
manual. The charger and battery pack are specifically designed to work together.
• These chargers are not intended for any uses other than charging P
teries. Any other uses may result in risk of fire, electric shock or electrocution.
• Do not allow charger to get wet.
• DO NOT ABUSE CORD. Never carry charger by cord or yank to disconnect from receptacle. Pull
by plug rather than cord when disconnecting charger. This will reduce risk of damage to electric plug and
cord. Have damaged or worn power cord and strain relief replaced immediately.
• Make sure that cord is located so that it will not be stepped on, tripped over, or otherwise sub-
jected to damage or stress.
• Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could
result in risk of fire, electric shock, or electrocution.
• An extension cord must have adequate wire size (AWG or American Wire Gauge) for safe-
ty. The smaller the gauge number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. When using more than one extension cord to
make up the total length, be sure each individual extension cord contains at least the mini-
mum wire size. If an extension cord is to be used outdoors it must be marked with the suffix
W-A or W following the cord type designation. For example – SJTW-A to indicate it is acceptable for
outdoor use.
• Do not place any object on top of charger or place the charger on a soft surface that might block
the ventilation slots and result in excessive internal heat. Place the charger in a position away from
any heat source.
• Do not operate charger with damaged cord or plug — have them replaced immediately.
• Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in
any way. Take it to an authorized service center.
• Do not disassemble charger; take it to an authorized service center when service or repair is
required. Incorrect reassembly may result in a risk of electric shock, electrocution or fire.
