SAFETY INSTRUCTIONS FOR POWER TOOLS
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 residual
current device (RCD) protected supply. Use of an RCD 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 inattention
while operating power tools may result in serious personal injury.
b) 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.
c) 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.
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 connected and properly used. Use of dust
collection can reduce dust-related hazards.
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.
WARNING: To reduce the risk of injury, user must read the instruction manual.
GENERAL POWER TOOL SAFETY WARNINGS
WARNING! 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 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) 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.

• Young children and the infirm. This appliance is not intended for use by young
children or infirm persons without supervision.
– This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
– Children should be supervised to ensure that they do not play with the appliance.
• Replacement of the supply cord. If the supply cord or plug is damaged, it must
be replaced by the manufacturer or an authorised DEWALT Service Centre in
order to avoid a hazard.
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 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.
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.
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 Specific Safety Rules for Jig Saws
• Hold power tools 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 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.
• Allow the motor to come to a complete stop before withdrawing the blade
from the kerf (the slot created by cutting). A moving blade may impact the
workpiece causing a broken blade, workpiece damage or loss of control and
possible personal injury.
• Keep handles dry, clean, free from oil and grease. This will enable better
control of the tool.
• Keep blades sharp. Dull blades may cause the saw to swerve or stall under
pressure.
• Clean out your tool often, especially after heavy use. Dust and grit containing
metal particles often accumulate on interior surfaces and could create an electric
shock hazard.
Electrical Safety
The electric motor has been designed for one voltage range only. Always check that
the power supply corresponds to the voltage on the rating plate. 220–240 V AC
means your tool will operate on alternating current. Operation at a voltage outside this
range 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 DEWALT
tool is double insulated, therefore no earth wire is required.

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 AS/NZS1716 approved
respiratory protection appropriate for the dust exposure. Direct particles away from
face and body.
