The definitions below describe the level of severity for each signal word. Please read the manual and pay attention to these symbols. DANGER: Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
English 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.
c) The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart. d) The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled. e) Threaded mounting of accessories must match the grinder spindle thread.
English Prolonged exposure to high intensity noise may cause hearing loss. h) Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation. i) Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring.
b) d) e) d) Wheels must be used only for recommended applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter. e) Always use undamaged wheel flanges that are of correct size and shape for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel flanges.
English d) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece. e) Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.

operation, flashing the red light with two fast blinks followed by a pause. This indicates the power source is out of limits. Charge Indicators Important Charging Notes 1. Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65 ˚F and 75 ˚F (18 ˚ – 24 ˚C). DO NOT charge the battery pack in an air temperature below +40 ˚F (+4.5 ˚C), or above +105 ˚F (+40.5 ˚C). This is important and will prevent serious damage to the battery pack. 2.
English charging procedure. You may also charge a partially used pack whenever you desire with no adverse effect on the battery pack. 6. Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug the charger before attempting to clean. 7.
The side handle (E) can be fitted to either side of the gear case in the threaded holes. Before using the tool, check that the handle is tightened securely. To improve user comfort, the gear case will rotate 90° for cutting operations. Rotating the Gear Case WARNING: To reduce the risk of serious personal injury, turn tool off and remove the battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. 1.

English 1. Open the guard latch (K), and align the FIG. 4 lugs (L) on the guard with the slots on L the gear case (M). This will align the lugs on the guard with the slots on the gear case cover. 2. Push the guard down until the guard lugs engage and rotate freely in the M groove on the gear case hub. K 3. With the guard latch open, rotate the guard (I) into the desired working position. The guard body should be positioned between the spindle and the operator to provide maximum operator protection. I 4.
until the battery pack is firmly seated in the tool and ensure that it does not disengage. To remove the battery pack from the tool, press the release button (O) and firmly pull the battery pack out of the tool handle. Insert it into the charger as described in the charger section of this manual. Switch FUEL GAUGE BATTERY PACKS (FIG. 7) Some DEWALT battery packs include a fuel gauge which consists of three green LED lights that indicate the level of charge remaining in the battery pack.
English MOUNTING NON-HUBBED WHEELS (FIG. 2, 9–10) WARNING: To reduce the risk of serious personal injury, turn tool off and remove the battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. Depressed center Type 27 and Type 42 grinding wheels must be used with included flanges. See pages 14 and 15 of this manual for more information. 1.

FIG. 10B Wheels 1/8" (3.17 mm) and thinner threaded locking flange threaded locking flange backing flange backing flange cut-off work. In all edge grinding/cutting operations, the open side of the guard must be positioned away from the operator. Edge grinding/ cutting with a Type 27 wheel must be limited to shallow cutting and notching—less than 1/2" (13 mm) in depth when the wheel is new. Reduce the depth of cutting/notching equal to the reduction of the wheel radius as it wears down.
English SURFACE FINISHING WITH SANDING FLAP DISCS (FIG. 13) 1. Allow the tool to reach full speed before touching the tool to the work surface. 2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. Sanding rate is greatest when the tool operates at high speed. 3. Maintain a 5° to 10° angle between the FIG. 13 tool and work surface. 4. Continuously move the tool in a 5˚–10˚ forward and back motion to avoid creating gouges in the work surface. 5.
Precautions To Take When Sanding Paint 1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the contaminated dust. The greatest danger of lead poisoning is to children and pregnant women. 2. Since it is difficult to identify whether or not a paint contains lead without a chemical analysis, we recommend the following precautions when sanding any paint: CLEANING AND DISPOSAL 1.
English Undetectable damage could occur to the accessory, causing wires to fragment from accessory wheel or cup. 5. Continuously move the tool in a forward and back motion to avoid creating gouges in the work surface. Allowing the tool to rest on the work surface without moving, or moving the tool in a circular motion causes burning and swirling marks on the work surface. 6. Remove the tool from the work surface before turning the tool off. Allow the tool to stop rotating before setting it down.
23 English CAUTION: Matching diameter backing flange and threaded locking flange (included with tool) must be used for Type 1 and Type 41 cutting wheels. 1. Place the unthreaded backing flange on spindle with the raised section (pilot) facing up. The raised section (pilot) on the backing flange will be against the wheel when the wheel is installed. 2. Place the wheel on the backing flange, centering the wheel on the raised section (pilot). 3.
