Technical Data

Noise values and vibration values (triax vector sum) according to EN62841-2-11:

The vibration and/or noise emission level given in this information sheet has been measured in accordance with a standardised test given in EN62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.

The declared vibration and/or noise emission level represents the main applications of the tool. However, if the tool is used for different applications, with different accessories or is poorly maintained, the vibration and/or noise emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration and/or noise 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 and/or noise such as: maintain the tool and the accessories, keep the hands warm (relevant for vibration), organisation of work patterns.

   2. Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorised service providers.

Safety Instructions for Reciprocating Saws

• Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. 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 workpiece by hand or against your body leaves it unstable and may lead to loss of control.

Additional Safety Instructions for Jig Saws

• Keep hands away from cutting area. Never reach underneath the workpiece for any reason. DO NOT insert fingers or thumb into the vicinity of the reciprocating blade and blade clamp. DO NOT stabilize the saw by gripping the shoe.
• Keep blades sharp. Dull or damaged blades may cause the saw to swerve or stall under pressure. Always use the appropriate type of saw blade for the workpiece material and type of cut.
• When cutting pipe or conduit, make sure that they are free from water, electrical wiring, etc.
• DO NOT touch the workpiece or the blade immediately after operating the tool. They can become very hot.
• Be aware of hidden hazards, before cutting into walls, floors or ceilings, check for the location of wiring and pipes.
• The blade will continue to move after releasing the switch. Always switch the tool off and wait for the saw blade to come to a complete standstill before putting the tool down.

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 accidents caused by the uncovered parts of the saw blade.
• Health hazards caused by breathing dust developed when sawing wood, especially oak, beech and MDF.

   2. For all angles between 0 ° and 45 °, lock with bevel lever only.

Cutting Action—Orbital or Straight (Fig. E)
This jig saw is equipped with four cutting actions, three orbital and one straight. Orbital action has a more aggressive 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 hardwoods should never be cut in orbital action. to adjust the cutting action, move the orbital action lever between the four cutting positions: 0, 1, 2, and 3. Position 0 is straight cutting. Positions 1, 2, and 3 are orbital cutting. The aggressiveness of the cut increase as the lever is adjusted from one to three, with three being the most aggressive cut.

Dust Blower (Fig. F)
The dust blower helps clear the cutting area of debris created from the blade.

Dust Extraction (Fig. A, G)

Dust can be hazardous to health. Always work with a dust extractor. Always observe the national regulations for work with dust emitting tools.
The dust extraction chute in combination with the dust extraction shroud helps extract dust from the workpiece surface, when connected to a suitable dust extraction system.
NOTE: The tool will not bevel if the dust extraction accessories are attached to the tool.

1. Place the dust extraction shroud onto the finger guard (Fig. A) until it clicks into place.
2. Slide the dust chute from the back of the tool until it snaps into the dust shroud. Be sure the adapter end is facing up.

The required setting depends on the thickness and kind of material.
NOTE: Use high speeds for sawing soft materials such as wood.

DCS335
The speed control dial can be used for advance setting of the required range of speed.

1. Turn the electronic control dial to the required level. The DCS335 will turn on at that speed when the on/off switch is moved to the ON position. The required setting depends on the thickness and kind of material.
   NOTE: Use high speeds for sawing soft materials such as wood.

OPERATION

Instructions for Use

Always observe the safety instructions and applicable regulations.

To reduce the risk of serious personal injury, turn tool off and disconnect battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

Always wear proper personal hearing protection. Under some conditions and duration of use, noise from this product may contribute to hearing loss.

• Make sure your workpiece is well secured. Remove nails, screws and other fasteners that may damage the blade.
• Check that there is sufficient space for the blade underneath the workpiece. DO NOT cut materials that are thicker than the maximum cutting depth.
• Use sharp saw blades only. Damaged or bent saw blades must be removed immediately.
• Never run your tool without a saw blade.
• For optimal results, move the tool smoothly and constantly over the workpiece. DO NOT exert lateral pressure on the saw blade. Keep the shoe flat on the workpiece. When sawing curves, circles or other round shapes, push the tool gently forward.
• Wait until the tool has come to a standstill before removing the saw blade from the workpiece. After sawing the blade may be very hot. DO NOT touch.

Proper Hand Position (Fig. K)

To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown.

To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction.

To start the DCS335 jig saw, move the on/off switch to the ON position. To turn the jig saw off, move the on/off switch to the OFF position.

Worklights
The worklights are located on either side of the blade. To turn on the worklight, depress the trigger (DCS334) or switch on the on/off switch (DCS335). Worklights will remain on 20 seconds after the tool is turned on, or as long as your cut lasts.
NOTE: The worklights are for lighting the immediate work surface and are not intended to be used as a flashlight.

Cutting

The jig saw should not be operated with the shoe removed or serious personal injury may result.

Pocket Cutting (Fig. L)
A pocket cut is an easy method of making an inside cut. The saw can be inserted directly into a panel or board without first drilling a lead or pilot hole. In pocket cutting, measure the surface to be cut and mark clearly with a pencil. Next tip the saw forward until the front end of the shoe sits firmly on the work surface and the blade clears the work through its full stroke. Switch the tool on and allow it to attain maximum speed. Grip the saw firmly and lower the back edge of tool slowly until the blade reaches its complete depth. Hold the shoe flat against the wood and begin cutting. DO NOT remove blade from cut while it is still moving. Blade must come to a complete stop.

Flush Cutting (Fig. M)
A flush cut is necessary when finishing off cuts up to a wall or an obstacle, such as back‑splash. One of the easiest ways to accomplish the flush cut is to use a flush cutting blade (DT2074). The flush cutting blade provides the reach necessary to cut 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 in the 0 or 1 orbital position. The flush cutting blade should not be used to start the cut because the flush cutting blade prevents the shoe from being supported by the work surface. Use wood cutting practices explained below.

Wood Cutting
Support 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 stall 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 tool; let the blade cut at its own speed. When the cut is complete, turn the jig saw off. Let blade come to a complete 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 will insure a clean cut without the risk of vibration or tearing of metal. Always remember to use a finer blade for ferrous metals (for those that have a high iron content); and use a coarser blade for non‑ferrous 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.

MAINTENANCE

Your power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.

To reduce the risk of serious personal injury, turn tool off and disconnect battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. The charger and battery pack are not serviceable.
