Melting of resin material caused by high heat generated during cutting may cause the band saw blade to become bound to the material, possibly resulting in overload and burn-out of the motor. BLADE DESCRIPTION Type of band saw blade Bi-Metal Number of teeth per inch 24 18 14 10 14/18 Workpiece thickness 1/8" and under •• 1/8"- 1/4" • • 1/4" - 13/32" • 13/32" and over • 10/14 • Blade Speed Your DW328 portable band saw is equipped with variable speed for greater versatility. Turn the speed wheel (I) to select the desired speed (Fig. 1). Speed 1 is the slowest speed; Speed 6 is the fastest. Use speed settings 1-6 when connected to an AC power supply. When connected to a DC power supply the setting MUST be Speed 6. CAUTION: To avoid damage to the variable speed switch, always use Speed 6 (fastest) when using a DC power source. Always turn the saw off, set the speed wheel (I) to Speed 6, then turn the saw on. When cutting copper, brass, bronze, aluminum, cast iron, angle iron, and mild steel, use a higher speed. When cutting plastic pipe, tougher steels, chrome steel, tungsten steel, stainless steel, and other problem materials, use low speed. NOTE: When cutting plastic pipe, higher speeds may melt plastic. Removing and Installing Blades WARNING: Turn off and unplug the tool before making any adjustments or removing/installing attachments or accessories. CAUTION: Cut Hazard. Blade tension lever is under spring pressure. Maintain control of lever when releasing blade tension or blade may be released causing personal injury. TO REMOVE BLADE (FIG. 1, 2) 1. Rotate the blade tension lever (H) clockwise until it stops to release tension in blade. 2. Turn the saw over and place it on a workbench or table with the cord to the left. 3. Begin removing the blade at the blade guard (M) and continue around the pulleys (L). When removing the blade, tension may be released and the blade may spring free. SAW BLADES ARE SHARP. USE CARE IN HANDLING THEM. 4. Inspect the guide rollers (F1, F2) and remove any large chips which may be lodged in them. Lodged chips can prevent rotation of the guide rollers and cause flat spots on the guide rollers. 5. Rubber tires (K) are mounted on the pulleys (L). The rubber tires should be inspected for looseness or damage when changing the blade. Wipe any chips from the rubber tires on the pulleys. This will extend tire life and keep the blade from slipping. If any looseness or damage occurs, the tool should be brought to an authorized DEWALT service center for repair or replacement as soon as possible. Continued use of the tool with loose or damaged rubber tires will cause unstable travel of the band saw blade. TO INSTALL BLADE 1. Position the blade so that the teeth are on the bottom and angled toward the material guide/work stop, as shown in Figures 1 and 3. 2. Slip the blade into the guide rollers (F), as shown in Figure 4. 3. Holding the blade in the guide rollers, place it around both pulleys (L) and through the material guide/work stop (E), as shown in Figure 5. 4. Make sure that the blade is fully inserted into the guide rollers (F) and positioned squarely against the rubber tires (K). 5. Gently turn the saw over so that the pulleys rest on your work bench or table and rotate the blade tension lever (H) counterclockwise until it stops. Make sure the teeth face away from the bandsaw (Fig. 1, 3). 6. Turn the saw on and off a few times to ensure that the blade is seated properly. Blade Tracking WARNING: Turn off and unplug the tool before making any adjustments or removing/installing attachments or accessories. Your band saw is equipped with an adjustable blade tracking mechanism which assures proper blade tracking at all times. The back edge of a properly aligned blade will run lightly against one or both of the back up rollers in the blade guides. (The pressure between the edge of the blade and the roller will be very slight and will not damage either the blade or the roller.) TO ADJUST THE BLADE TRACKING 1. Use a 9/16" (20mm) wrench to loosen the adjustment locking nut (G), shown in Figure 1 by turning it one or two turns counterclockwise. 2. Use a screwdriver to turn the tracking screw 1/4 turn. Turning the screw clockwise will move the blade up toward the blade guide rollers. Turning the screw counterclockwise will move the blade down away from the rollers. 3. Adjust so that the back edge of the blade lightly touches the rollers then securely tighten the locking nut. (It will be necessary to plug the saw in and run it to observe the tracking.) 4. Observe blade tracking between runs and repeat Steps 1-4 as necessary to achieve proper blade tracking.
