WARNING: To reduce the risk of injury, user must read the instruction manual. 1 GENERAL POWER TOOL SAFETY WARNINGS 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. 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. 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. 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. 2 – 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.

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 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 area. • 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. • Young children and the infirm.

Pull blade clamp release lever (C) up (Fig. 3). 2. Insert blade shank from the front. 3. Push blade clamp release lever down. NOTE: The blade can be installed in four positions as shown in Figure 4. The blade can be installed upside-down to assist in flush-to cutting as shown in Figure 7. OPERATION 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. 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. TO REMOVE BLADE FROM SAW CAUTION: Burn hazard. Do not touch the the blade immediately after use. Contact with the blade may result in personal injury. 1. Open up blade clamp release lever. 2. Remove blade. 5 FIG. 3 C 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. Shoe 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. 6 FLUSH-TO CUTTING (FIG. 7) 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 METAL CUTTING (FIG. 9) 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. POCKET/PLUNGE CUTTING – WOOD ONLY (FIG. 8) 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 MAINTENANCE 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. Lubrication Your power tool requires no additional lubrication. 7 Cleaning 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.
