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.
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.
WARNING! Read all safety warnings and all instructions Failure to follow
the warnings and instructions may result in electric shock, fire and/or serious
The term “power tool” in the warnings refers to your mains-operated (corded) power
tool or battery-operated (cordless) power tool.
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.
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
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.
– 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.
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.
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 Reciprocating 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.
• 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.
• Hold saw firmly with both hands for all cutting operations. During cutting
operations, the blade may suddenly bind in the work and may cause the saw to
kickback towards the operator.
• Keep hands away from moving parts. Never place your hands near the cutting
• 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.
• Do not operate this tool for long periods of time. Vibration caused by the
operating action of this tool may cause permanent injury to fingers, hands, and
arms. Use gloves to provide extra cushion, take frequent rest periods, and limit
daily time of use.
• Air vents often cover moving parts and should be avoided. Loose clothes,
jewellery or long hair can be caught in moving parts.
WARNING: We recommend the use of a residual current device with a residual
current rating of 30mA or less.
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.

Blade Installation and Removal (Fig. 2–4, 7)
WARNING: To reduce the risk of serious personal injury, turn tool off and
disconnect tool from power source before making any adjustments or removing/
installing attachments or accessories. An accidental start-up can cause injury.
Different blade lengths are available. Use the appropriate blade for the application. The
blade should be longer than 89 mm (3-1/2") and should extend past the shoe and the
thickness of the workpiece during the cut. Do not use jigsaw blades with this tool.
WARNING: Cut hazard. Blade breakage may occur if the blade does not extend past
the shoe and the workpiece during the cut (Fig. 2). Increased risk of personal injury, as
well as damage to the shoe and workpiece may result.

Cutting (Fig. 5–9)
FIG. 4
WARNING: Always use eye protection. All users and bystanders must wear eye
protection that conforms to ANSI Z87.1.
WARNING: Exercise extra caution when cutting towards operator. Always hold saw
firmly with both hands while cutting.
Before cutting any type of material, be sure it is firmly anchored or clamped to prevent
slipping. Place blade lightly against work to be cut, switch on saw motor and allow it
to obtain maximum speed before applying pressure. Whenever possible, the saw shoe
must be held firmly against the material being cut (Fig. 6). This will prevent the saw
from jumping or vibrating and minimize blade breakage. Any cuts which put pressure
on the blade such as angle or scroll cuts increase potential for vibration, kickback, and
blade breakage.
Proper Hand Position (Fig. 1, 5–9)
WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand
position as shown.
WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in
anticipation of a sudden reaction.
Proper hand position requires one hand on the main handle (B), with the other hand
on the hand grip (E).
Cutting with Blade in Horizontal
Position (Fig. 5)
FIG. 6
FIG. 5
Your DWE357-XE is equipped with a
horizontal blade clamp. Installing a blade
in the horizontal orientation allows cutting
close to floors, walls or ceilings where
limited clearance is available. Ensure that
the shoe is pressed against the framing to
avoid kickback.
WARNING: 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: Inspect work site for hidden gas pipes, water pipes or electrical wires
before making blind or plunge cuts. Failure to do so may result in explosion, property
damage, electric shock, and/or serious personal injury.
CAUTION: Cut hazard. To prevent loss of
control, never use tool without shoe.
The DWE357-XE comes with a fixed shoe
that is not adjustable.
The compact design of the saw motor housing and
spindle housing permits extremely close cutting to
floors, corners and other difficult areas.
NOTE: In areas where blade visibility is limited, use the edge of the saw shoe as a
guide. Lines for any given cut should be extended beyond edge of cut to be made.
FIG. 7
FIG. 9
Your saw has different metal
cutting capacities depending
upon type of blade used and
the metal to be cut. Use a
finer blade for ferrous metals
and a coarse blade for nonferrous materials. In thin
gauge sheet metals it is best
to clamp wood to both sides
of sheet. This will ensure a
clean cut without excess
vibration or tearing of metal.
Always remember not to
force cutting blade as this
reduces blade life and causes
costly blade breakage.
NOTE: It is generally recommended that when cutting metals you should spread a thin
film of oil or other lubricant along the line ahead of the saw cut for easier operation and
longer blade life.
The initial step in pocket cutting is to measure the
surface area to be cut and mark clearly with a pencil,
chalk or scriber. Use the appropriate blade for the
application. The blade should be longer than 89 mm
(3-1/2") and should extend past the shoe and the
thickness of the workpiece during the cut. Insert blade
in blade clamp.
FIG. 8
WARNING: To reduce the risk of serious personal injury, turn tool off and
disconnect tool from power source before making any adjustments or removing/
installing attachments or accessories. An accidental start-up can cause injury.
Next, tip the saw backward until the back edge of the shoe is resting on the work
surface and the blade clears the work surface (position 1, Fig. 8). Now switch motor
on, and allow saw to come up to speed. Grip saw firmly with both hands and begin a
slow, deliberate upward swing with the handle of the saw, keeping the bottom of the
shoe firmly in contact with the workpiece (position 2, Fig. 8). Blade will begin to feed
into material. Always be sure blade is completely through material before continuing
with pocket cut.
Your power tool requires no additional lubrication.
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once
a week. To minimize the risk of eye injury, always wear AS/NZS1337 approved eye
protection when performing this.
WARNING: Never use solvents or other harsh chemicals for cleaning the
non-metallic parts of the tool. These chemicals may weaken the plastic materials
used in these parts. Use a cloth dampened only with water and mild soap. Never let
any liquid get inside the tool; never immerse any part of the tool into a liquid.
To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment
(including brush inspection and replacement) should be performed by certified
service centers or other qualified service organizations, always using identical
replacement parts.
