General Safety Instructions

A ARNING! Read and understand all instructions. Failure to follow all instruc-

tions listed below, may result in electric shock, fire and/or serious _ersonal injury,

SAVE THESE INSTRUCTIONS

WORK AREA

* Keep your work area clean and weft fit. Cluttered benches and dark areas invite accidents. * Do not operate power tools in explosive atmospheres, such as in the presence of flam-

mable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

* Keep bystanders, children, and visitors away while operating apower tooL Distractions

can cause you to losecontrol.

ELECTRICAL SAFETY

* Grounded tools must be plugged into an outlet properly installed and grounded in

accordance with aft codes and ordinances. Never remove the grounding prong or

modify the plug in any way. Do not use any adaptor plugs. Check with a qualified elec- trician if you are in doubt as to whether the outlet is properly grounded, ff the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. Applicable only to Class I (grounded) tools.

* Double insulated tools are equipped with a polarized plug (one blade is wider than the

other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation _ elim- inates the need for the three wire grounded power cord and grounded power supply system.

Applicable only to Class II (double insulated) tools.

* Avoid body contact with grounded surfaces such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric shock if your body is grounded.

* Don't expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

, Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an

outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

* When operating a power tool outside, use an outdoor extension cord marked "W-A"

or "W." These cords are rated for outdoor use and reduce the risk of electric shock. When using an extension cord, be sure to use one heavy enough to carry the current your product

will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-

ber, the heavier the cord.

PERSONAL SAFETY

* Stay alert, watch what you are doing and use common sense when operating a power

tooL Do not use tool while tired or under the influence of drugs, alcohol, or medica- tion. A moment of inattention while operating power tools may result in serious personal injury

* Dress properly. Do not wear loose clothing orjewelry. Contain long hair. Keep your hair,

clothing, and gloves away from moving parts. Loose clothing, jewelry, or long hair can be caught in moving parts. Air vents often cover moving parts and should also be avoided.

* Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with

your finger on the switch or plugging in tools that have the switch on invites accidents.

* Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that

is left attached to a rotating part of the tool may result in personal injury.

* Do not overreach. Keep proper footing and balance at all times. Proper footing and bal-

ance enables better control of the tool in unexpected situations.

* Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,

hard hat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE

* Use clamps or other practical way to secure and support the workpiece to a stable

platform. Holding the work by hand or against your body is unstable and may lead to loss of

control.

* Do not force tooL Use the correct tool for your application. The correct tool will do the

job better and safer at the rate for which it is designed.

* Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with

the switch is dangerous and must be repaired.

* Disconnect the plug from the power source before making any adjustments, changing

accessories, or storing the tool Such preventative safety measures reduce the risk of

starting the tool accidentally.

* Store idle tools out of reach of children and other untrained persons. Tools are dan-

gerous in the hands of untrained users.

* Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools,

with sharp cutting edges are less likely to bind and are easier to control.

* Check for misalignment or binding of moving parts, breakage of parts, and any other

condition that may affect the tool's operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

* Use only accessories that are recommended by the manufacturer for your model

Accessories that may be suitable for one tool, may become hazardous when used on

another tool.

SERVICE

* Tool service must be performed only by qualified repair personnel Service or mainte-

nance performed by unqualified personnel could result in a risk of injury

* When servicing a tool, use only identical replacement parts. Follow instructions in the

Maintenance section of this manual Use of unauthorized parts or failure to follow mainte- nance instructions may create a risk of electric shock or injury.

Additional Specific Safety Instructions for Jig Saws

, Hold tool by insulated gripping surfaces when performing an operation where the cut-

ting 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.

* Allow the motor to come to a complete stop before withdrawing the blade from the kerr

(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. Duff 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 par-

ticles often accumulate on interior surfaces and could create an electric shock hazard.

* 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.

WARNING: Always wear eye protection while operating this power tool.

_ WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con- struction activities contains chemicals known to cause cancer, birth defects or other reproduc- tive 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 weft ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscop-

ic 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 hearing protection during use. Under some conditions and

duration of use, noise from this product may contribute to hearing loss. * The label on your tool may include the following symbols. The symbols and their definitions

Motor

Your DEWALT tool is powered by a DEWALT-built motor. Be sure your power supply agrees with the nameplate markings.

Volts 50/60 Hz or "AC only" means your tool must be operated only with alternating current and

never with direct current. Volts DC-60 Hz or AC/DC means your tool may be operated with either

alternating or direct current. Voltage decrease of more than 10% will cause loss of power and overheating. All DEWALT tools

are factory tested; if this tool does not operate, check the power supply.

OPERATION Trigger Switch (Fig. 1)

To start the jig saw, squeeze the trigger switch (A). To slow and stop the jig saw, release the trigger switch.

Cuttireg ActiOn - Orbital or StraLqht (Fig. 5)

htkCAUTION: Check that tire tool is fret lecked ON before corrnect#rg it to a power supply, If tire

tti_Iger swit{;h is locked ON wheo the too! is cennc<:ted to the power supply, it will start #nmedi- a_l_ Damage to your tool or personal irrjury nray result:

This jig saw is equipped with four cutting actions three orbital and or_e straight. Orbital action has a more agglessive blade motion and is designed for cutting in soft materials like wood or plastic. Orbital action provides a faster cut, but with a less smooth cut across the material In orbital action, the blade moves forward during the cutting stroke in addition to the up and down

motion. NOTE: Metal or hardwoc_Js should never be cut in orbital action.

To adjust the cutting action, move the cutting action [ever (G) between the four cutting pesi-

tk)ns: 0, 1, 2, and 3, Position 0 is straight cuttin9_ Positions !, 2, and 3 are orbital cutting, T'he

aggressiveness of the cut increase as the lever is adiusted from one to three, with three being

the most aggressive cut.

Dusft Blower fFig. 6)

The dust blowel helps clear the cutting area oI debris created from the blade, NOTE: When cutting metal, turn the dust blower off so cutting fluids are not blown away from

the blade.

To turn the dust blower on, slide the dust blower control (H) all the way to the top. To turn the dust blower off, slide the dust blower control all the way to the bottom

Ren_ovable No-Mar Shoe Cover (Fig. 7)

_f're no-mar shoe cover (I) should be used when cutting surlaces that scratch easily, such as laminate, veneer, or paint.

To attach no-mar shoo cover, place the front of the aluminum shoe (F) into the front of the no- mar shoe cover (I) and lower the jig saw. The no-mar shoe will click securely onto the rear of

aluminum shoe. To remove no-mar shoe cover_ grasp the no-mar shoe cover from the bottom: holding onto the

two rear tabs (M) remove the no-mar shoe cover.

AretJ-Splinter Iresert (Fig= 8)

NOTE: Do not use the anti-splinter insert with the flush cuttirlg btade. The arrti-splinter insert (J) should be used when trying to minimize tear-out, especially when cut-

ting veneel, laminate, or finished surfacee, such as paint. The anti-splinter insert should be

installed into the no-mar shoe cover (I) If the nomar cover is not used, install antFsplinter insert into shoe (F).

A WARNING: The j_g saw should not be operated with the shoe removed or serious personal

injt#y may result.

POCKET CUTTING (FIG, 10} A pocket cut is an easy method of making an inside cut. The saw can be inserted directly into a pane! or _ard without first drilling a lead or pilot hole, In pocket cutting, measure the sudace to be cut and mark clearly with a pencil Nexl tip the saw forward until the front end oH the shoe sits firmly on the work surface arrd the blade clears the work through its full stroke. Sw_ch the t(×_f on and aIIow it to altain rnaximurr} speed. Grip the saw firmly and lower the back _dge of tool slowly until the blade roaches its complete depth. Hold the shoe flat against the weod and begin cutting. Do

not remove blade from cut whila it is still moving. Blade must come to a complete stop. FLUSH CUTTING (FIG, 9)

A flush cut is necessary when finishing off cuts up to a wall or an ob.stacle, such as back-splash One of the easiest ways to accomplish the flush cut is to u_ a flush cutting blade (DT2074). The

flush cutting blade provides the reach necessary to cuff right up to the front edge of the jig saw

shoe. Remove the anti-splinter insert and return the shoe to the 0 ° positive stop position before installing and using the flush cutting blade. For the best cut quality the flush cutting blade should be used [n the 0 or I orbital position, The flush cutting blade should net be used to start the cut because the f_ush cutting blade prevents the shoe flom being supported by the work surface. Use wood cutting practices explained below.

WOOD CUTTING Sup_x>rt the workpiece adequately at all times. Use the higher speed setting for cutting wood

Do not attempt to turn the tool on when blade is against material to be cut, This could stal! the motor. Place the front of shoe on the material to be cut and hold the jig saw shoe firmly against

the wood while cutting. Don't force the too!: let the blade cut at its own speed. When the cut is complete, turn the jig saw off, Let blade come to a comp}ete stop and then lay the saw aside before loosening the work.

METAL CUTTING In cutting thin gauge sheet metals, it is best to clamp wood to the bottom of sheet metal; this wit!

insure a clean cut without the risk of vibration or tearing of metal. Always r÷member to use a finer blade for ferrous metals (k)r those that have a high iron content); and use a coarser blade for non-

ferreus metals (those that do not have an iron content), Use a high speed setting for cutting soft

metals (aluminum, copper, brass, mild steel, galvanized, pipe, conduit sheet metal, etc.). Use lower speed to cut plastics, tile, laminate, hard metals, and cast iron_

C_ean_reg

CAUTION: Never use solvents or othe_ harsh chemicals fer cleaning the non-metallk: 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. Do not use gasoline, turpentine, lacquer or paint thinner dry cleaning fluids or similar products.

Never let any liquid get inside the tool; never immerse any part oH the too{ into a liquid
