English Paddle Switch (Fig. A) CAUTION: Hold the neck and the body of the tool firmly to maintain control of the tool at start up and during use and until the wheel or accessory stops rotating. Make sure the accessory has come to a complete stop before laying the tool down. CAUTION: Before connecting the tool to a power source depress and release the paddle switch 7 once without depressing the lock-on button 9 (DWE4997VS Only) to ensure that the switch is off. Depress and release the paddle switch as described above after any interruption in power supply to the tool, such as the activation of a ground fault interrupter, throwing of a circuit breaker, accidental unplugging, or power failure. NOTE: To reduce unexpected tool movement, do not switch the tool on or off while under load conditions. Allow the grinder to run up to full speed before touching the work surface. Lift the tool from the surface before turning the tool off. Allow the tool to stop rotating before putting it down. 1. To turn the tool on, push the lock-off lever 8 toward the back of the tool, then depress the paddle switch 7 . The tool will run while the switch is depressed. 2. Turn the tool off by releasing the paddle switch. Lock-On Button (Fig. A) DWE4997VS Only The lock-on button 9 offers increased comfort in extended use applications. To lock the tool on,depress the lock-on button while the tool is running. The tool will continue to run after the switch is released. To unlock and turn off the tool, depress and release the switch. NOTE: A grinder should never be locked ON by any other means. LED Worklight (Fig. A) CAUTION: Do not stare into worklight. Serious eye injury could result. The worklight 13 located around the collet is activated as soon as the tool is powered. The worklight will stay illuminated as long as the tool is powered. NOTE: The worklight is for lighting the immediate work surface and is not intended to be used as a flashlight. Spindle Lock (Fig. A) The spindle lock button 2 is provided to prevent the spindle from rotating when installing or removing accessories. Operate the spindle lock only when the tool is turned off, unplugged from the power supply, and has come to a complete stop. NOTICE: To reduce the risk of damage to the tool, do not engage the spindle lock while the tool is operating. Damage to the tool will result and attached accessory may spin off possibly resulting in injury. To engage the lock, depress the spindle lock button and rotate the spindle by hand until you are unable to rotate the spindle further. Precautions to Take When Working on a Painted Workpiece (Fig. D) 1. Sanding or wire brushing 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: Personal Safety 1. No children or pregnant women should enter the work area where the paint sanding or wire brushing is being done until all clean up is completed. 2. A dust mask or respirator should be worn by all persons entering the work area. The filter should be replaced daily or whenever the wearer has difficulty breathing. NOTE: Only those dust masks suitable for working with lead paint dust and fumes should be used. Ordinary painting masks do not offer this protection. See your local hardware dealer for the proper N.I.O.S.H. approved mask. 3. NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingesting contaminated paint particles. Workers should wash and clean up BEFORE eating, drinking or smoking. Articles of food, drink, or smoking should not be left in the work area where dust would settle on them. Environmental Safety 1. Paint should be removed in such a manner as to minimize the amount of dust generated. 2. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils thickness. 3. Sanding should be done in a manner to reduce tracking of paint dust outside the work area. Cleaning and Disposal 1. All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the duration of the sanding project. Vacuum filter bags should be changed frequently. 2. Plastic drop cloths should be gathered up and disposed of along with any dust chips or other removal debris. They should be placed in sealed refuse receptacles and disposed of through regular trash pick-up procedures. During clean up, children and pregnant women should be kept away from the immediate work area. 3. All toys, washable furniture and utensils used by children should be washed thoroughly before being used again. 8
