If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. • Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool. SERVICE • Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury. • When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury. Additional Specific Safety Rules • Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • lead from lead-based paints, • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemically-treated lumber (CCA). Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. • The label on your tool may include the following symbols.

The further the trigger is depressed the higher the speed of the saw. To turn the tool “OFF” release the trigger. CAUTION: Use of very slow speed is recommended only for beginning a cut. Prolonged use at very slow speed may damage your saw. Speed Range Selector Wheel DW309, (Fig. 2) A variable speed selector wheel has been provided to control the speed of the tool. To select a slow speed for operating your saw, rotate the wheel to a low number on the dial. To select a higher speed, rotate the wheel to a higher number. Adjustable Shoe (Fig. 3) CAUTION: TURN OFF AND UNPLUG SAW. The shoe will adjust to limit the depth of cut. Hold the saw with the underside facing up. Push the button on the hand grip and slide the shoe out to one of the three settings and release the button. Blade Clamp Release Lever (Fig. 4) CAUTION: TURN OFF AND UNPLUG SAW. To install blade into saw: 1. Open blade clamp release lever up. 2. Insert blade shank from the front. 3. Close blade clamp release lever down. To Remove blade from saw: 1. Open up blade clamp release lever. 2. Remove blade. Operation CAUTION: Always wear eye protection while operating this or any other power tool. Flush-To Cutting (Fig. 5) The compact design of the saw motor housing and spindle housing permits extremely close cutting to floors, corners and other difficult areas. CAUTION: When sawing into walls, floors or wherever “live” electrical wires may be encountered, DO NOT TOUCH ANY FRONT METAL PARTS OF THE TOOL! Hold the tool only by the plastic or rubber handle and housing to prevent electric shock if you saw into a “live” wire. Wood Cutting (Fig. 6) Before cutting any type of wood, be sure it is firmly anchored or clamped to prevent slipping. Place blade lightly against work to be cut, switch on saw motor and allow it to obtain maximum speed before applying pressure. Always hold saw firmly with both hands while cutting. Whenever possible, the saw shoe must be held firmly against the material being cut. This will prevent the saw from jumping or vibrating and minimize blade breakage. Metal Cutting (Fig. 7) This unit has different metal cutting capacities depending upon type of blade used and the metal to be cut. Use a finer blade for ferrous metals and a coarse blade for non-ferrous materials. In thin gauge sheet metals it is best to clamp wood to both sides of sheet. This will insure a clean cut without excess vibration or tearing of metal. Always remember not to force cutting blade as this reduces blade life and causes costly blade breakage. To prolong blade life, use other areas of the blade ...
