WARNING: To reduce the risk of injury, user must read instruction manual.
General Safety Rules
WARNING! Read all instructions. Failure to follow all instructions listed below
may result in electric shock, fire 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
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) 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 earth-
ed 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. Replace or repair damaged cords.
Make sure your extension cord is in good condition. 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. 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 gage. The smaller the gage
number, the heavier the cord.

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
drugs, alcohol 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
conditions will reduce personal injuries.

Not Recommended
c) Avoid accidental starting. Ensure the switch is in the off-position before plugging
in. Carrying power tools with your finger 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 jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in
moving parts. Air vents often cover moving parts and should also be avoided.
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
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 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 and/or 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.
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
instructions and in the manner intended for the particular type of power tool, 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.
5) 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
• Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring. Contact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
• 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 hands away from moving parts. Never place your hands near the cutting area.
• Keep hands away from cutting area. When sawing, never reach underneath or behind the
material being cut for any reason.
• Never hold work in your hand, lap or against parts of your body when sawing. The saw
my slip and the blade could contact the body causing injury.
• Use extra caution when cutting overhead and pay particular attention to overhead
wires which may be hidden from view. Anticipate the path of falling branches and debris
ahead of time.

WARNING: Always use eye protection. All users and bystanders must wear eye protection
that conforms to ANSI Z87.1.
CAUTION: When not in use, place tool on its side on a stable surface where it will not
cause a tripping or falling hazard. Some tools with large battery packs will stand upright on
the battery pack but may be easily knocked over.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• 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.
WARNING: 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.
• The label on your tool may include the following symbols. The symbols and their definitions
are as follows:

TRIGGER SWITCH
The variable speed trigger switch (A) will give you added versatility. The further the trigger is
depressed the higher the speed of the saw. To turn the tool OFF, release the trigger.
NOTE: This tool has no provision to lock the switch in the ON position, and should never be
locked ON by any other means.
CAUTION: Use of very slow speed is recommended only for beginning a cut. Prolonged use at
very slow speed may damage your saw.
VARIABLE SPEED SWITCH AND SELECTOR WHEEL
Both saws are equipped with a variable speed control (0 to 2600 SPM). As the trigger switch is
depressed, the speed of the saw blade increases.
The DW311 has a variable speed selector wheel (B) to control the speed of the tool. To select a
slow speed for operating your saw, rotate the wheel to a low number on the dial. To select a high-
er speed, rotate the wheel to a higher number.
The lower speeds are recommended for most metal cutting, while the higher speeds are
recommended for wood. A few practice cuts on scrap material at various speeds will aid you in
choosing the best speed for obtraining the desired results for your application.
