SAFETY INSTRUCTIONS FOR POWER TOOLS
When using power tools, always observe the safety regulations applicable in your country to reduce the risk of fire, electric
shock and personal injury. Read the following safety instructions before attempting to operate this product. Keep these
instructions in a safe place.
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
a. Keep work area clean and well lit. Cluttered and 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 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.

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 inatten-
tion 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.
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.
g. If devices are provided for the connection of dust extraction and collection facilities, ensure these are con-
nected 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 before making any adjustments, changing accessories, or stor-
ing 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 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 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.
Electrical Safety
The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the volt-
age on the rating plate. 240 V AC means your tool will operate on alternating current. As little as 10% lower voltage can
cause loss of power and can result in overheating. All DEWALT tools are factory tested; if this tool does not operate,
check the power supply. Your D
EWALT tool is double insulated, therefore no earth wire is required.
Young children and the infirm. This appliance is not intended for use by young children or infirm persons without
supervision. Young children should be supervised to ensure that they do not play with this appliance.
Replacement of the supply cord. If the supply cord is damaged, it must be replaced by the manufacturer or an
authorised DEWALT Service Centre in order to avoid a hazard.
Extension Cords
CAUTION: Use only extension cords that are approved by the country’s Electrical Authority. Before using extension
cords, inspect them for loose or exposed wires, damaged insulation and defective fittings. Replace the cord if necessary.
Additional Safety Instructions for Chop Saws
Always wear proper eye and respiratory protection.
Before using, inspect the cutting wheel for cracks or flaws. If such a crack or flaw is evident, discard the
wheel. The wheel should also be inspected whenever you think the tool may have been dropped. Flaws may
cause wheel breakage.
When starting the tool with a new or replacement wheel or if you are unsure of the condition of the wheel, hold
the tool in a well protected area and let it run for one minute. If the wheel has an undetected crack or flaw, it should
burst in less than one minute. Never start the tool with a person in line with the wheel. This includes the operator.
In operation, avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and inspect the wheel
for cracks or flaws.
Clean your chop saw periodically following the procedure in this manual.
Do not remove wheel guards or base.
ALWAYS USE THE VISE OR SPECIAL FIXTURE TO CLAMP WORK SECURELY. Other aids such as spring, bar, or C-
clamps may be appropriate for certain sizes and shapes of workpiece. Use care in selecting and placing these
clamps and make a dry run before making a cut.
Use only 355mm (14") type 1 wheels rated at 4100 rpm or higher.
Allow cut off parts to cool before handling.
Do not attempt to cut wood, plastic, masonry or non-ferrous metals with this tool.
NEVER CUT MAGNESIUM WITH THIS TOOL.
Use chop saw in a well-ventilated area.
Turn chop saw off before removing any pieces from the base.
DO NOT CUT ELECTRICALLY LIVE MATERIAL.
Do not use circular saw blades or any other toothed blades with this tool. Serious injury may result.
DO NOT OPERATE THIS TOOL NEAR FLAMMABLE LIQUIDS, GASES OR DUST. Sparks or hot chips from cutting or
arcing motor brushes may ignite combustible materials.
Do not use the side of the abrasive wheel as a deburring grinder. This will substantially weaken the wheel creating
an unsafe condition. The wheel may come apart
WARNING: 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 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.
CAUTION: Wear appropriate personal hearing protection during use. Under some conditions and duration of use,
noise from this product may contribute to hearing loss.
CAUTION: Spark deflector will get hot. Avoid touching or adjusting while hot. Keep cordset and materials away from
spark deflector.
