The vibration emission level given in this information
sheet has been measured in accordance with a
standardised test given in EN 60745 and may be
used to compare one tool with another. It may be
used for a preliminary assessment of exposure.
WARNING: The declared vibration
emission level represents the main
applications of the tool. However if the
tool is used for different applications,
with different accessories or poorly
maintained, the vibration emission may
differ. This may significantly increase the
exposure level over the total working
period.
An estimation of the level of exposure to
vibration should also take into account
the times when the tool is switched off
or when it is running but not actually
doing the job. This may significantly
reduce the exposure level over the total
working period.
Identify additional safety measures to
protect the operator from the effects of
vibration such as: maintain the tool and
the accessories, keep the hands warm,
organisation of work patterns.

WARNING: To reduce the risk of injury,
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.
E NG L I S H
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.
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
e)
f)
g)
part of the power tool may result in personal
injury.
Do not overreach. Keep proper
footing and balance at all times. This
enables better control of the power tool in
unexpected situations.
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.
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.
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.
25
EN GLI S H
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 Safety Rules for Alligator
Saws
• Hold power tool by insulated gripping
surfaces, when performing an operation
where the cutting accessory 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.
Residual Risks
In spite of the application of the relevant safety
regulations and the implementation of safety
devices, certain residual risks cannot be avoided.
These are:
– Impairment of hearing.
– Risk of personal injury due flying particles.
– Risk of burns due to accessories becoming hot
during operation.
– Risk of personal injury due to prolonged use.

Sawing (fig. 1, 3, 4, 6)
NOTICE: Do not use the saw for cutting
curves or pockets. Make sure the bar
end protrudes from the workpiece.
For long, straight cuts first draw a line on the
workpiece and follow the line.
Make downward cuts only. Avoid cutting earth as
this will blunt the saw blades very quickly.
When using a saw horse always cut on the outside
of the saw horse arms.
1. Clamp the workpiece on one side only to
prevent the bar from jamming in the workpiece.
Should this happen, ease open the cut with
wedges to relieve the strain on the blade. Do
not try to wrench the saw free.
2. Hold your DEWALT power tool by the front
handle (d) and the rear grip handle (c) to guide
the saw properly.
