Dewalt DW443 Instruction Manual - Page 4

English 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. Double Insulation Double insulated tools are constructed throughout with two separate layers of electrical insulation or one double thickness of insulation between you and the tool's electrical system. Tools built with this insulation system are not intended to be grounded. As a result, your tool is equipped with a two prong plug which permits you to use extension cords without concern for maintaining a ground connection. NOTE: Double insulation does not take the place of normal safety precautions when operating this tool. The insulation system is for added protection against injury resulting from a possible electrical insulation failure within the tool. CAUTION: When servicing all tools, USE IDENTICAL REPLACEMENT PARTS. Repair or replace damaged cords. Polarized Plug This product is supplied with a polarized plug (one blade is wider than the other). This plug will fit into a polarized outlet (receptacle) only one way. If the plug does not fit fully into your outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a proper polarized outlet. Do not modify or change this plug in any way. Extension Cords Make sure your extension cord is in good condition. 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 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 number, the heavier the cord. Minimum Gage for Cord Sets Volts Total Length of Cord in Feet 120V 0-25 26-50 51-100 101-150 240V 0-50 51-100 101-200 201-300 Ampere Rating More Not more AWG Than Than 0 -6 18 16 16 14 6 - 10 18 16 14 12 SAVE THESE INSTRUCTIONS FOR FUTURE USE Motor Be sure your power supply agrees with nameplate marking.120 AC means your tool may be operated only with alternating current and never with direct current. Voltage decrease of more than 10% will cause loss of power and overheating. All tools are factory tested; if this tool does not operate, check the power supply. Attaching Sanding Discs Your sander is designed to use 6" sanding discs with the 6 hole dust extraction pattern. Hook and Loop (DW442 and DW443) PSA - Pressure Sensitive Adhesive (DW441 and DW444) To attach paper to the sanding pad: 1. Turn off and unplug tool. 2. Turn the sander over so that the sanding pad is facing upward. 3. (DW441 and DW444 only) Clean dust from vinyl pad face. 4. Hold the pad with one hand to keep it from rotating. 5. With the other hand, align the holes and place the disc directly on top of the pad (see FIG. 1). 2
