ASSEMBLY AND ADJUSTMENTS  WARNING: To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start‑up can cause injury. MAXIMUM CUTTING DEPTH 90 1-3/4" (44 mm) 45 1-1/4" (31 mm) Changing Blades To Install the Blade (Fig. A, D)  WARNING: Remove battery before service, adjustment, installing or removing accessories. 1. Place inner clamp washer 19 on saw spindle 16 properly. 2. Retract the lower blade guard 7 and place blade 15 on saw spindle against the inner clamp washer 19 , making sure that the blade will rotate in the proper direction (the direction of the rotation arrow on the saw blade and the teeth must point in the same direction as the direction of rotation arrow on the lower blade guard). Do not assume that the printing on the blade will always be facing you when properly installed. When retracting the lower blade guard to install the blade, check the condition and operation of the lower blade guard to assure that it is working properly. Make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut. 3. Place outer clamp washer 18 on saw spindle with the large flat surface against the blade with beveled side facing out. 4. Thread blade clamping screw 8 into saw spindle by hand (screw has left-hand threads and must be turned counterclockwise to tighten). 5. Depress the blade lock button 20 while turning the saw spindle with the blade wrench 14 until the blade lock engages and the blade stops rotating. 6. Tighten the blade clamping screw firmly with the blade wrench. NOTE: Never engage the blade lock while saw is running, or engage in an effort to stop the tool. Never turn the saw on while the blade lock is engaged. Serious damage to your saw will result. To Replace the Blade (Fig. A, D)  WARNING: Remove battery before service, adjustment, installing or removing accessories. 1. To loosen the blade clamping screw 8 , depress the blade lock button 20 and turn the saw spindle with the blade wrench 14 until the blade lock engages and the blade stops rotating. With the blade lock engaged, turn the blade clamping screw clockwise with the blade wrench (screw has left-hand threads and must be turned clockwise to loosen). English 2. Remove the blade clamping screw 8 and outer clamp washer 18 only. Remove old blade. 3. Clean any sawdust that may have accumulated in the guard or clamp washer area and check the condition and operation of the lower blade guard as previously outlined. Do not lubricate this area. 4. Select the proper blade for the application (see Blades). Always use blades that are the correct size (diameter) with the proper size and shape center hole for mounting on the saw spindle. Always assure that the maximum recommended speed (rpm) on the saw blade meets or exceeds the speed (rpm) of the saw. 5. Follow steps 2 through 6 under To Install the Blade, making sure that the blade will rotate in the proper direction. Lower Blade Guard  WARNING: The lower blade guard is a safety feature which reduces the risk of serious personal injury. Never use the saw if the lower blade guard is missing, damaged, misassembled or not working properly. Do not rely on the lower blade guard to protect you under all circumstances. Your safety depends on following all warnings and precautions as well as proper operation of the saw. Check lower blade guard for proper closing before each use as outlined in Further Safety Instructions for All Saws. If the lower blade guard is missing or not working properly, have the saw serviced before using. To assure product safety and reliability, repair, maintenance and adjustment should be performed by an authorized service center or other qualified service organization, always using identical replacement parts. Checking the Lower Guard (Fig. A) 1. Turn tool off and disconnect from power supply. 2. Rotate the lower blade guard retracting lever 6 from the fully closed position to the fully open position. 3. Release the lever and observe the guard 7 return to the fully closed position. The tool should be serviced by a qualified service center if it: • fails to return to the fully closed position, • moves intermittently or slowly, or • contacts the blade or any part of the tool in all angles and depth of cut. 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.  WARNING: Do not cut metal, plastic, concrete, masonry or fiber cement materials with this saw. 11
