ENGLISH Trigger Switch (fig. 1) WARNING: This tool has no provision to lock the trigger switch in the ON position and should never be locked ON by any other means. Release the trigger switch lock-off button (a) by pressing the button as shown. Pull the trigger switch (b) to turn the motor on. Releasing the trigger switch turns the motor off. Depth of Cut Adjustment (fig. 1, 3) 1. Loosen the depth adjustment lever (d). 2. Move the shoe (e) to obtain the correct depth of cut. 3. Tighten the depth adjustment lever (d). 4. For optimal results, allow the saw blade to protrude from the workpiece by about 3 mm (see inset in figure 3). Bevel Adjustment (fig. 4) The bevel angle can be adjusted between 0° and 50°. 1. Loosen the bevel adjustment knob (j). 2. Set the bevel angle by tilting the saw shoe (e) until the mark indicates the desired angle on the scale. 3. Tighten the bevel adjustment knob (j). Shoe Adjustment for 90° Cuts (fig. 1, 5) 1. Adjust the saw to 0° bevel. 2. Retract the blade guard using the lever (f) and place the saw on the blade side. 3. Loosen the bevel adjustment knob (j). 4. Place a square against the blade and shoe to adjust the 90° setting. 5. Turn the calibration screw (q) so that the shoe will stop at the proper angle. 6. Confirm the accuracy of the setting by checking the squareness of an actual cut on a scrap piece of material. Rip Guide Installation and Usage (fig. 6) Ripping is the process of cutting wider boards into narrow strips, cutting the grain lengthways. Hand guiding is more difficult for this type of sawing and the use of the rip guide is recommended. WARNING: For your own safety, read the instruction manual before using any accessory. Failure to heed these warnings may result in personal injury and serious damage to the saw and accessory. When servicing this tool, only use identical replacements. ASSEMBLY 1. Loosen the rip guide knob (o). 2. Insert the rip guide (p) as shown in figure 6. 3. Tighten the rip guide knob (o) securely. Use the supplied rip guide only with the DCS391 circular saw. Use of this rip guide with other saws may increase the risk of kickback and injury. Before making a cut, ensure the rip fence is securely fastened to the tool. After installing the rip guide on the saw or after moving the guide to change the rip width setting, check the operation of the lower guard before starting the saw and making a cut to make sure that the rip guide does not affect proper guard operation. Replacing the Saw Blade (fig. 7) 1. Engage the blade lock button (k) and unscrew the blade clamping screw (h) by turning clockwise using the hex key supplied with the tool. 2. Retract the lower blade guard (g) using the lever (f) and replace the blade. Reinstall the washers (r, s) in the correct position. 3. Check the direction of rotation of the blade. 4. Thread on the blade clamping screw (h) by hand to hold the washer in position. Turn anticlockwise. 5. Press the blade lock button (k) while turning the spindle until the blade stops rotating. 6. Tighten the blade clamping screw firmly using the hex key. Blades WARNING: To minimize the risk of eye injury, always use eye protection. Carbide is a hard but brittle material. Foreign objects in the workpiece such as wire or nails can cause tips to crack or break. Only operate saw when proper saw blade guard is in place. Mount blade securely in proper rotation before using, and always use a clean, sharp blade. 43
