(emission sound pressure level) dB(A) 80

(sound power level) dB(A) 91

(uncertainty for the given sound level) dB(A) 3 Vibration emission value a

= m/s² <2.5 Uncertainty K = m/s² 1.5 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. 125 mm (5") PALM GRIP SANDER DWE642319 ENGLISH 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.

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 undersigned is responsible for compilation of the technical file and makes this declaration on behalf of D EWALT. Horst Grossmann Vice President Engineering DEWALT, Richard-Klinger-Straße 11, D-65510, Idstein, Germany

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.

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.

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.20 ENGLISH metals. Do not operate the tool near flammable liquids, gases or dust. Sparks or hot particles from sanding or arcing motor brushes may ignite combustible materials.

WARNING: We recommend the use of

a residual current device with a residual current rating of 30mA or less. Sanding Paint

WARNING: Observe the applicable

regulations for sanding paint. Pay special attention to the following:

• Whenever possible, use a vacuum extractor for dust collection.

• Take special care when sanding paint which is possibly lead based: – Do not let children or pregnant women enter the work area. – All persons entering the work area should wear a mask specially designed for protection against lead paint dust and fumes. – Do not eat, drink or smoke in the work area.

• Dispose of dust particles and any other removal debris safely. 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. Markings on Tool The following pictograms are shown on the tool: Read instruction manual before use. DATE CODE POSITION (FIG. 1) The Date Code (h), which also includes the year of manufacture, is printed into the housing. Example: 2015 XX XX Year of Manufacture 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.

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 Specifi c Safety Rules for Sanders

WARNING: Always observe the safety

instructions and applicable regulations.

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.

• Make sure all materials to be sanded are well secured.

• Apply only a gentle pressure to the workpiece. Excessive pressure does not improve the sanding effect, but only results in an increased load on the machine and causes the abrasive to tear.

NOTICE: If you wrap the cord around the tool when you store it, leave a generous loop of cord such that the strain relief (g, Fig. 1) does not bend. This helps prevent premature cord failure. Proper Hand Position (Fig. 5)

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 either one hand on the sander body (j) or one hand on the main grip (p) as shown. Switching On and Off (Fig. 1) Set the sanding speed using the electronic speed control dial (b). To switch the tool on, set the on/off switch to position I. To switch the tool off, set the on/off switch to position O. Setting the Electronic Speed Control Dial (Fig. 1) The speed is infinitely variable from 8,000–12,000 min

using the electronic speed control dial (b). Turn the electronic speed control dial to the required level. The correct setting, however, is a matter of experience. Generally, harder materials require a higher setting. Dust Extraction (Fig. 3, 4)

WARNING: Since woodworking with a

sander produces dust, always install a dust bag designed in compliance with the applicable directives regarding dust emission.

WARNING: Do not use a dust bag or

vacuum extractor without proper spark protection when sanding metal. Your sander has two dust extraction methods: a built-in outlet (c) which allows either the supplied dust bag (d) or a shop vacuum system to be connected; and a dust skirt (n, Fig. 4). The built-in outlet utilizes the DEWALT airlock connection making it compatible with the DEWALT dust extractor and airlock accessory DWV9000.

TO ATTACH THE DUST BAG

1. While holding the sander, fit the dust bag collar

(e) to the outlet (c) as shown in Figure 3.

2. Turn the collar (e) clockwise to lock the dust

NOTE: Be sure to wear approved eye protection and approved dust mask when performing this procedure. For efficient dust extraction, empty the dust collector when it is about one third full.

1. While holding the sander, turn the collar (e)

anticlockwise to unlock the dust bag (d).

2. Remove dust bag from the sander and gently

shake or tap the dust bag to empty.

3. Reattach the dust bag back onto the outlet and

lock into place by turning the dust bag collar clockwise. You may notice that all the dust will not come free from the bag. This will not affect sanding performance but will reduce the sander’s dust collection efficiency. To restore your sander’s dust collection efficiency, depress the spring inside the dust bag when you are emptying it and tap it on the side of the waste bin or dust receptacle.23 ENGLISH Lubrication Your power tool requires no additional lubrication. Cleaning NOTE: After the tool is used in metal sanding applications without dust bag, clean the tool using low-pressure air.

WARNING: Blow dirt and dust out of

the main housing with dry air as often as dirt is seen collecting in and around the air vents. Wear approved eye protection and approved dust mask when performing this procedure.

WARNING: Never use solvents or

other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the 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. Optional Accessories

WARNING: Since accessories, other

than those offered by DEWALT, have not been tested with this product, use of such accessories with this tool could be hazardous. To reduce the risk of injury, only DEWALT, recommended accessories should be used with this product. Consult your dealer for further information on the appropriate accessories. Protecting the Environment Separate collection. This product must not be disposed of with normal household waste. Should you find one day that your DEWALT product needs replacement, or if it is of no further use to you, do not dispose of it with household waste. Make this product available for separate collection. Sanding Start with the coarsest grit size. As the tool produces small abrasion marks in all directions, it is not necessary to sand with the grain. Check your work at short intervals. Always switch off the tool when work is finished and before unplugging. MAINTENANCE Your DEWALT 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.

WARNING: To reduce the risk of

injury, turn unit off and disconnect machine from power source before installing and removing accessories, before adjusting or changing set-ups or when making repairs. Be sure the trigger switch is in the OFF position. An accidental start-up can cause injury. Replacing the Sanding Pad and the Speed Limiter Belt (Fig. 4) Your sander is equipped with a replaceable belt (m) which is located between the pad (f) and the sander body (j). It is designed to control the pad speed while the unit is off the work surface. The belt and the sanding pad (f) are designed to be consumable parts and will occasionally need to be replaced. The sanding pad needs replacement when signs of wear become evident. Replacement of the belt is necessary when the pad speed increases very dramatically when the unit is lifted from the work surface. These parts are available at extra cost from your local dealer or authorised D EWALT service centre.

1. Holding the platen firmly, remove the four

screws (o) from the bottom of the pad.

2. Remove the pad (f).

3. Replace worn or damaged belt (m) by wrapping

it around the shoulder screw (k) and bearing retainer (l) as shown in Figure4.

4. Reinstall pad (replace with new pad if

necessary). Replace the four screws (o). Be careful not to over-tighten screws.24 ENGLISH Separate collection of used products and packaging allows materials to be recycled and used again. Re-use of recycled materials helps prevent environmental pollution and reduces the demand for raw materials. Local regulations may provide for separate collection of electrical products from the household, at municipal waste sites or by the retailer when you purchase a new product.
